Schizophrenia is one of the most misunderstood mental disorders that psychologist must treat in the field today.  In this paper, we have extensively studied the environmental, genetic, and biological influences of the disorder.  We have looked at how they affect the development of schizophrenia, and what treatments are currently available for patients suffering from this terrifying disease.  While there is no cure for schizophrenia, researchers continue to study the disease because the symptoms of this mental illness require lifetime care and medicine.  Through the study of Shonda, who is diagnosed with paranoid schizophrenia and suffering a psychotic episode, we explore a comprehensive view of this devastating illness.

Introduction
Among all of the mental disorders that affect our society, schizophrenia is one of the hardest to deal with as stated by the University of Texas Harris County Psychiatric Center at Houston (1997).  This is attributed to the vast array of symptoms both positive and negative, such as delusions, hallucinations, alogia, and affective flattening to name a few.  This disorder according to Barlow and Durand (2007) is divided into five subtypes, paranoid, catatonic, residual, disorganized, and undifferentiated, which further complicates this disease.  In this paper, we intend to shed some light on this disorder, discuss genetic, environmental and biological influences on the disorder, treatments, and relate this research and study to a specific case of paranoid schizophrenia.
What Exactly is Schizophrenia?
According to the University of Texas Harris County Psychiatric Center at Houston (1997), of all of the mental disorders it is possible to have, schizophrenia is one of the most convoluted and misconstrued of them all.  The symptoms that define this disease are horrifying and frightening to the patients, their families, and even to society as a whole. Patients suffer from audible and visual hallucinations according to Barlow and Durand (2007), along with delusions, and catatonia.  They also suffer from negative symptoms such as alogia, negative flattening, and avolition.  These symptoms are the most prevalent in the disorder regardless of the type of schizophrenia that you have, as there are five different subtypes associated with schizophrenia, paranoid, catatonic, undifferentiated, residual, and disorganized (Johns Hopkins Medicine, n.d.).
Each of these subtypes present differently, contributing to the general public misconception of this complex disease (Barlow and Durand, 2007). While the delusions and hallucinations are the main symptoms across the subtypes, and considered positive symptoms, the complete set of symptoms, is much larger and include negative symptoms as well, such as avolition, alogia, anhedonia, and affective flattening.  This disorder also manifests disorganized symptoms including disorganized speech, and catatonic immobility.  While it has happened that, the disease has manifested earlier and later in life, the disease usually presents in young adults in their twenties and early thirties, according to Barlow and Durand (2007).
Cola, Findling, Lee, Meltzer, Rabinowitz, Ranjan, and Thompson (1997), note that there are several factors, which change the degree of the disorder in relation to the age of onset.  They find that the earlier the onset, the greater level of dysfunction the disorder produces in the patient, along with inferior response to treatments, and the greater chance of having to be hospitalized more than once during the patient’s lifetime. Although mental disorders have been around for “thousands of years” as stated by Johns Hopkins Medicine (n.d.), Emil Kraeplin was the first person to separate mental conditions into different classifications, calling what is now known as schizophrenia, dementia praecox.  In 1911 the term schizophrenia, was adopted by Eugen Bleuler, and both he and Kraeplin had subdivided the disease into the five different subtypes by this time.  The current classification system for mental disorders according to Johns Hopkins Medicine (n.d.) is the Diagnostic and Statistical Manual for Mental Disorders –Fourth Edition (DSM-IV-TR).
schizotheclown.glogster.com
The DSM-IV-TR classifies schizophrenia as an unrelenting, chronic disease, which affects the patient’s thinking process, emotions, and even behavior, holds BehaveNet (2011).  In order for a patient to receive a classification of schizophrenia, certain diagnostic criteria must be met, from a range of criterion listed in the DSM-IV divided into six categories.  These categories, described as characteristic, social/occupational dysfunction, persistent duration, the ruling out of schizoaffective and mood disorders, the exclusion of substance or medical related psychosis, and finally whether there is any presence of pervasive developmental disorder all have different durations to meet the criteria.  After one year of persistent symptoms, the disorder can be further classified as episodic with interepisode residual symptoms, with or without prominent negative symptoms, episodic without interepisode residual symptoms, continuous, and other unspecified pattern symptoms as well.  There is also a classification for single episodes with partial or full remission notes BehaveNet (2011). 
BehaveNet (2011) goes on to say that while normally there needs to be two or more of the symptoms classified to receive a diagnosis of schizophrenia, but that if the characteristic symptoms are delusions or hallucinations, it is possible to give a diagnosis under certain conditions.  These conditions state that extreme or fantastic delusions, more than one voice communicating together, or even a single hallucination continuously talking about the patient’s behavior or even their thoughts would warrant the diagnosis of this disorder.  Finally, BehaveNet (2011) spans the original diagnosis to six months of behavior pointing to the disease, with a person having to exhibit two or more characteristic symptoms for a month, and six months of periodic social/occupation dysfunction or signs of disruption attributed to the disorder (BehaveNet, 2011).  This information is the result of numerous studies done concerning schizophrenia, including twin studies, family studies, adoptee studies, offspring of twin studies, and linkage studies (Barlow and Durand, 2007).These studies confirm that, it is not simply one gene that causes schizophrenia, but rather a combination of multiple genes that actually cause one to be more susceptible to both schizophrenia and other psychotic disorders as stated by Barlow and Durand (2007). During an experiment that proves, that there is a definite correlation to the severity to which the parents were affected by the disease, and the chances that their offspring would follow suit and develop schizophrenia done by Frank Kallmann.  One other fact learned during this study is that the subtype of schizophrenia that one receives genetically is not correlated to the type that your family member is suffering from.  From the studies on twins, research has concluded that it has to be both genetic and environmental factors that contribute to the presentation of the disorder.
During studies of the offspring of twins, it was discovered that it is possible to be a carrier of the disorder, and able to pass it down genetically without ever having shown signs of the disorder, notes Barlow and Durand (2007).  Genetic linkage association studies have shown that the easiest way to study disorders of this type are through marker genes, and receptors.  In schizophrenics, this means the study of the dopamine process in the brains of patients.  Now, we should look at the research and what the DSM-IV-TR says, and compare it to our original case study about Shonda Wilson. 
We can see from the facts detailed in Figure 1, that Shonda has been diagnosed with continuous paranoid schizophrenia, and has had the diagnosis of schizophrenia for many years.  According to BehaveNet (2011) and the DSM-IV-TR, she does seem to fit the criteria for this disorder.  Shonda has had audible hallucinations and alogia throughout the entire time she has had the diagnosis.  The fact that the hallucinations are constantly present is what qualifies her for the diagnosis of continuous paranoid schizophrenia.

However, even with the addition of a new antipsychotic medicine (Haldol), her condition seems to be worsening.  Now, along with the hallucinations, which are getting more insistent and frightening, and the alogia, Shonda is also delusional and unable to function at work.  She believes that the FBI and CIA are monitoring her and have put cameras in her house and workplace, and her hallucinations have turned harsh, critical, and insistent. When considering the research, Cola, Findling, Lee, Meltzer, Rabinowitz, Ranjan, and Thompson (1997), have stated that the earlier the onset of the disorder, the less positive results that are found by treatment, and that seems to be the case here.
Although Shonda has not had much contact with her family, and not much is known about her history, we can see that there is some mental disorder in the family, as there was emotional distance by both, mother and father, alcoholism, and violence, along with an aunt who was hospitalized.  Not enough is known about this aspect of her past to make justifiable considerations to diagnosis and research in this case, however we can speculate that it is possible that the violence and abuse that the mother may have endured during the pregnancy as a suspected cause.  It is important to explore the biological, genetic, and environmental aspects of this disorder anyway.
Biological and Genetic Aspects of Schizophrenia
Yale University School of Medicine, Psychiatry (2005), holds that the main neurotransmitter involved in schizophrenia is dopamine, however there are actually three neurotransmitters involved according to the National Institute of Mental Health (NIMH) (2004).  The dopamine neurotransmitter was the first one related to schizophrenia, but glutamate has been related to this disorder for some time now.  The glutamate receptor GR3, which regulates the amount of glutamate present in the synaptic clefts, relates to possible negative impacts on cognitive functions.  Recently, NIMH (2007) has also associated GABA with schizophrenia, and it is because of the reduction of enzymes such as the gene GAD1, which aids in the production of the neurotransmitter GABA that affects schizophrenics’ development of the disorder.
Barlow and Durand (2007) tie the distinction of genetics to schizophrenia by making this statement, “we can safely make one generalization: Genes are responsible for making some individuals vulnerable to schizophrenia”.  There have been numerous findings in relation to genetics and schizophrenia such as the one by Frank Kallmann.   It is a quantitative trait locus, which offers us the best explanation into the variances of the disease.  This includes why we have gradations of severity, and that the studies show the correlation between the number of family members with the disease and the chances of developing it increasing with the addition of each new family member diagnosed (Barlow and Durand, 2007).  Along with the genetic studies, there have been proven abnormalities in the brain structure of schizophrenics.
The Journal of Psychiatry and Neuroscience (2002) maintains that schizophrenia as a disease of the brain, and that it has always been classified in this way.  Now that researchers have the MRI, and Computed Topography (CT), it is much easier to see these abnormalities.  What they see is that patients have lateral ventricles that appear larger than normal while cortical grey matter and hippocampal masses appear to be smaller than normal. Barlow and Durand (2007, p490 par3-4) report that the disease is at least caused in part by “excessive stimulation of striatal dopamine D2 receptors” and by the “deficiency in the stimulation of prefrontal D1, receptors”.  You will find them in the basil ganglia and the prefrontal cortex.  Scientists also have gone into another newer area that has been researched, which takes modifications in the prefrontal cortex action that regulates glutamate communication into consideration.  This modified interaction between the dopamine receptors happens in conjunction with the N-methyl-d-aspartate (NMDA) receptors in the brain, and was discovered by studying effects of certain drugs on the brain (Barlow and Durand, 2007).
Barlow and Durand (2007) states that the frontal lobes seem to maintain less activity in people diagnosed with schizophrenia than those in other people.  Particularly this hypofrontality is found in the dorsolateral prefrontal cortex in these patients, and presents earlier than other cognitive dysfunctions in relation to schizophrenia and other symptoms and signs.   There is also new research as of August 2011, showing a definite link to 40 mutations in different genes in cases of sporadic (non-hereditary) schizophrenia holds Priedt (2011).  This study also notes that most of these are protein altering, and that Columbia University Medical Center staff who did this research think that the finding of the “de novo mutations” has changed the face of schizophrenia study drastically (Priedt, 2011).
What the patient experiences, because of the biological abnormalities is a diminished ability to react to emotional and social situations, and have experiences in which they may see or hear things that are in reality not there (Barlow and Durand, 2007).  They may also take direction from these hallucinations, and have beliefs that are unlikely, or even impossible.  This applies to Shonda as well; as we remember that she believes that, the CIA and FBI are spying on her and hearing voices continually. She is also experiencing alogia.  Because schizophrenia affects everyone differently, the patient could also have a combination of lack of speech, lack of emotional expression, inability to move, and or a lack of motivation, along with difficulty processing and retrieving information (Barlow and Durand, 2007).

There is no known cure for schizophrenia, however according to Barlow and Durand (2007); there are treatments to minimize the frightening symptoms of the disorder.  Usually this is done by administering antipsychotic medications, and psychosocial treatments along with developing social, physical, and cognitive skills to help patients cope.  This is designed to minimize relapses, reduce hospitalization, help to regulate their medicine, and help them develop skills they may be personally lacking.  The antipsychotic drugs available to treat schizophrenia fall into four classes, Phenothiazines (Chloropromazine/Thorazine, or Fluphenazine/Proloxin for example), Butyrophenones (Haldol), Others (Loxapine/Loxitane for example), and Second Generation Agents (Ariprazole/Abilify, Clozapine/Clozaril, or Quetiapine/Seroquel for examples of these) (Barlow ad Durand, 2007).  While these medicines work to reduce and regulate the dopamine system and our neurotransmitters, and are effective in that respect, they often produce side effects that are equally annoying such as drowsiness, rapid heartbeat, dizziness, sensitivity to the sun, and lowered libido (NIMH, 2004).  The Surgeon General (1999) also states that patients with this disorder suffer severe symptoms that affect our most basic human functions such as “language, thought, perception, affect, and sense of self”.  
Psychosocial therapy models include several treatments designed to improve the quality of life that the patients have notes Barlow and Durand (2007).  The behavior therapy model is used to teach family members of schizophrenics’ tools to deal with the family member that has the disorder.   Patients go through a model called the token economy model that teaches appropriate actions and behavior by rewarding them when they act appropriately through a token system.  Another example of psychosocial therapy models is the independent living program that helps patients recapture some independence by helping them gain skills they are lacking to function in society and gain a higher quality of life (Barlow and Durand, 2007)
Environmental Aspects Influencing Schizophrenia
Although there are biological and genetic factors, there are also some environmental factors, which associate with triggers beginning the onset of this disorder according to Leask (2004).  He goes on to say, that there have been various studies, which explore the environmental influences on the development of schizophrenia, also taking the particular subtypes associated with the disease into consideration.  They study such environmental factors like the season a person is born, the geographical location they live in, immigration status, and even substance abuse along with their actual birthplace, which is often referred to as urbanisation.  The studies refer to these as external environmental influences.

Another type of study that has been researched is the environment that the patient experienced while in the womb, because we are in the early stages of neural and physical development during this time (Leask, 2004).  He also discusses that the nuclear environment is a cyclic factor because environment influences genetic reactions and then genetic reactions influence behavior, which in turn affects environmental reactions.  
According to Leask (2004), studies have shown that people born in the winter and spring in the north hemisphere, and those born in the spring in the south hemisphere of the earth are at risk, an extra 5% - 8% for presenting with schizophrenia later in life.  Geographically, it is proven that developing countries have a higher presence of schizophrenia by a considerable amount.  This, he goes on to say is based on the first-rank symptoms as defined by the IC-9, and the Present State Examination (PSE).  The World Health Organization (WHO), conducted this study involving ten countries, “Colombia, Czechoslovakia, Denmark, England, India, Ireland, Japan, Nigeria, the USA and the (then) USSR” reports Leask (2004), involving both rural and urban areas coming up with this conclusion.
Ten different studies involving urbanisation resulted in the conclusion that at least one third of all cases of schizophrenia is attributed to this factor, notes Krabbendam and van Os (2005).  If you look at the science, it can be said that he reason for this is the overcrowded, poor conditions that people live in urbanized areas, has undesirable consequences on developing neurological functions of young minds.  The statistics prove that this disorder develops in urban conditions in excess of two to one over rural area development of schizophrenia.  Krabbendam and van Os (2005) also pointed out that the ten studies prove that there is a direct correlation between having genetic predisposition to schizophrenia and urbanisation.

Leask (2004) discusses immigrant status as an environmental influence, particularly Norwegian, Danish and African Caribbean immigrants are effected, but states that because of the immigrant status it is hard to conduct and maintain studies and data because they can be undocumented or migrant in nature.  He also mentions that due to differences in cultural norms, this disorder may not be diagnosed as often.  Another environmental factor that should be noted is substance abuse, however inconclusive the results are, because patients diagnosed with schizophrenia have considerably higher rates of abuse than other people do. Leask (2004) brings up at least one more environmental factor, prenatal influences.
The prenatal theory about schizophrenia is founded on the reflection that patients with this disorder are different from other people in the way they process thoughts, behaviors, brains structure, and their pathological histories holds Leask (2004).  A few of the influences that affect the neurological development of children are prenatal stress, prenatal famine, prenatal influenza, and obstetric complications while the child is in utero.  Other influences of this nature notes Leask (2004), include low birth weight, pre-eclampsia, and Rhesus incompatibility.  This makes sense, when one considers the importance of our earliest neurological development.  A final environmental factor that can influence this disease is viral infection, which can alter brain performance (Barlow and Durand, 2007).
There are also psychosocial factors that are considered environmental, for example, stress, high expressed emotion, and reactions within families that contain schizophrenia according to Barlow and Durand (2007).  When people genetically predisposed to schizophrenia experience a major loss such as death, loss of a job, or combat situations, this can act as a trigger, beginning the onset of the disorder.  It is often also found that families of schizophrenia patients will criticize them, treat them with hostility, or even over involve themselves with the person.  When this happens, researchers call it high expressed emotion and it can often cause or contribute to the patient’s relapse.  Even though there are many studies and conclusions, there is one environmental cause, which does seem to overshadow the rest as concluded by Leask (2004).
This is the urbanization theory, which as stated earlier accounts for a least one third of all schizophrenia patients as stated by Leask (2004).  This is the theory that holds that it is your geographic location and or birthplace that affects your chances of developing schizophrenia.  While prenatal influences and stress/loss do have plenty of merit, the statistics do not lie.  We do have to consider however, that all of the research really points to the fact that the nuclear environment, involving gene-environment reactions really is at the heart of this research. 
What this research concludes is that the environment influences genetic factors, as much as the environment is influenced by choices derived from genetic factors.  In schizophrenia, it seems that genetic predispositions can trigger environmental reactions.  The studies also conclude that one’s genetic propensities also can affect their behavior, which then has a direct effect on the environment that a person chooses (Leask, 2004).  This environmental effect has direct influence and interacts with the patient’s biological systems (Barlow and Durand, 2007).
Barlow and Durand (2007), conclude that there are only three neurotransmitter abnormalities in patients with schizophrenia, however NIMH (2007) states that there are four at work in schizophrenics’ brains.  The first three identified by Barlow and Durand (2007), are that the striatal dopamine D2 receptors, which are part of the basil ganglia, disrupt the functional movements such as walking, balance, and movement.  This is also responsible for deficiencies in the prefrontal D1 receptors.  Along with the dopamine receptors in the prefrontal cortex, there has been research into the modification of the receptors that regulate glutamate communication.
 This communication deals directly with N-methyl-d-aspartate (NMDA) (Barlow and Durand, 2007).  The fourth neurotransmitter involved, GABA, is affected by the reduction of enzymes such as the gene GAD1 that aid in the production of GABA (NIHM, 2007).  It is these interactions which cause the biggest changes in neurotransmitters and changes in the frontal lobes have also been noted which function to maintain less activity in people diagnosed with schizophrenia.  According to Barlow and Durand (2007), these cognitive dysfunctions begin to appear in patients before other symptoms and signs of the disease.
Again, we go back to our original case study, Shonda Wilson.  When considering the environmental influences on this case.  What we see is that she is a classic candidate for prenatal environmental influence on the disorder due to the abuse that her mother probably suffered during her pregnancy with Shonda.  At her age of onset, which was a mere 20 years of age, she can also be classified as an early age onset schizophrenic, since the disease does not usually affect women until their late twenties or early thirties.   Environmentally speaking, Shonda’s case really does fit into the nuclear environment theory.  We can see the probability that she was originally affected by abuse and stress emitted by her mother during the prenatal stages.  However, because of the situation with her parents being emotionally distant, and her father being an abusive alcoholic, we must also conclude that her environment also affects her throughout her entire life until the diagnosis and her moving away. 
What is the Best Treatment Approach for Schizophrenia and Shonda?
When considering how to treat this disorder, all options have been considered by researchers.  The conclusion has been reached, based on the research conducted on treatment options, that ECT, electroconvulsive therapy will help to end episodes of severe psychosis and mania, according to the Mayo Clinic (2010), but it has been redacted to limited use because of social factors and the lack of evidence that prolonged effects result from treatment.  It is obvious that the most effective means of treating schizophrenics has to be combined treatments.  This includes several elements of psychosocial models, behavior and cognitive models, all with included pharmacological options.  The complexity of this disease combined with the fact that there is no cure, only symptom treatments, denotes that there is no single treatment option that is effective alone.  The particular course of treatment needs to be tailored to the patient and their specific symptoms in order to reach the most effective method for treatment, which is based on the degree and frequency of the symptoms.
In the case study of Shonda Wilson, a paranoid schizophrenic should be receiving case management, cognitive therapies, and family treatments, however, in her specific case, she has no family so that may be excluded.  These therapies should be in conjunction with pharmacological treatments.  Since Shonda has been on antipsychotic medicines for the better part of twelve years already, and has recently been prescribed haloperidol (Haldol), she should have her medicine adjusted, since she had shown some improvements previously with Haldol it is recommended to stay with this medicinal approach.  For the immediate future, Shonda should be immediately hospitalized for stabilization.  While she remains hospitalized, careful adjustments of her medicine should be explored, as she will be monitored in this setting.  She already has a case management program, however while she is hospitalized she needs to be introduced to cognitive therapies, to aid in the reduction of the hallucinations and delusions, along with an independent treatment to serve in the place of the family therapy.  When she is stabilized, and released, this course of treatment should continue for a minimum of one year and longer if needed.
Conclusion
When considering the best model for understanding and treating schizophrenia, we will look at the psychodynamic model, the behavioral model, the humanistic model, and the cognitive model.  In relation to the psychodynamic model, Cooper, Michaels, and Perry (2006) convey that this will help the practitioner understand the nature of the delusions, meaning that it manifests because of fears they may be having about control, losing control, and being dependant and vulnerable.  This is important because an in depth understanding of the nature of the patient’s specific problems can help the therapist tailor the treatment to best suit client fears, problems, and needs.  The cognitive model looks at this differently according to McFarr (2010), with his model following the premise that they way a person views themselves, the world around them, and what they believe the future holds will influence their behavior.

This model, holds McFarr (2010), has been shown to be effective with helping patients remember to take their medicines which has long been a struggle.  Research also seems to point in the direction that this model has also been effective in other problems as well, including symptom management.  It has been definitively shown that patients who receive cognitive therapy have less frequent and extreme delusions and hallucinations.  With the cognitive model, the therapist can assist the patient in identifying faulty thinking patterns and interpretations, helping them to see reality (McFarr, 2010).
 It seems that the behavior model is also helpful in treating schizophrenia, but only when paired with cognitive therapy as well according to Bradshaw (2000).  If you are trying to understand or explain this disorder, however, this model suggests that every behavioral abnormality is to be explained by the social learning or learned behavior theory, holds Barlow and Durand (2007).  This cannot apply to schizophrenia because there are too many genetic and biological abnormalities in schizophrenics to attribute it to a real explanation.  We however, cannot discount, that there are many behavioral model therapies, which does help in the treatment of this disease.  Operant conditioning used in the form of the token economy for example would be one of them (Barlow and Durand, 2007).
The humanistic model suggests that self-actualization is the answer, and that we should realize the individuality of everyone, suggests Barlow and Durand (2007).  This model is actually more effective on people who do not have mental illness.  This does apply loosely to schizophrenia in the fact that the disorder presents, and changes in everyone individually regardless of their genetic and environmental history, which inherently affects both genetic and environmental factors. In deciding, what the bet model is for explaining and treating schizophrenia this author would have to go with the cognitive model if forced to choose just one.
This is because according to Barlow and Durand (2007), the cognitive model seems to help on many levels with this complicated disease.  The first way that this model is more effective is in aiding the patient to remember to take their medicines, as this was noted to be a problem for them.  The second way that this model is useful in understanding and treating these patients is the effectiveness that it helps to reduce the symptoms which is a huge problem in the way of patients leading productive lives.  The final way that this model is effective with the treatment and understanding the disease is because it can aid the therapist in retraining the patient to identify their faulty thinking patterns and correct them (McFarr, 2010).  It does need to be noted that all research indicates that this disorder is best treated using multiple treatment approaches including cognitive, behavioral and pharmacological treatments in conjunction with each other.
There have been new treatments explored recently involving possible pharmacological changes in the way therapists treat this disorder.  In a study conducted by NIH, scientists have found a rare gene mutation in roughly one third of schizophrenic patients.  They found that these patients “multiple copies of a gene on Chromosome 7, according to Asher (2011), specifically in the gene receptor VIPR2, which is the vasoactive intestinal peptide (VIP).  Other new treatments involve new medicines.
PsychCentral (2009) discusses a new drug that was approved by the Food and Drug Administration (FDA), called Saphris (asenapine), which is a new atypical antipsychotic associated with schizophrenia treatment.  It has proven to be effective when tested against a placebo, and has been on the market since 2009.  The adverse reactions to this pill, in schizophrenics, are that it makes them restless and unable to sit still.  Another treatment option according to Science Daily (2010), is working with serotonin, as it has a different signal pathway than traditional hallucinogens. 
This neurotransmitter affects our “perception, cognition, sleep, appetite, pain, and mood” notes Science Daily (2010).  The hypothesis is that the hallucinations in schizophrenia may actually arise due to elevated levels of serotonin.  Further study is needed in this matter; however, what is needed is a way to conserve the effects of the serotonin while at the same time, avoiding the harmful effects that come with excessive metabolites (Science Daily, 2010).  While there seem to be new treatments and research on this disorder, we must remember that there is no cure for this disease, and currently the only help manage the symptoms.
Unfortunately, for our case study subject Shonda Wilson, her future only seems to hold better symptom management and functionality in her life, as there is no current cure for this disorder according to our research.  In the immediate future, based on this research and study, Shonda should be immediately hospitalized for stabilization.  During this stabilization process, she should be monitored closely, while the doctors adjust her dosage of Haldol.  She should continue her case management program; however, she needs to be introduced to cognitive therapies, to aid in the reduction of the hallucinations and delusions, along with an independent treatment to serve in the place of the family therapy.  When she is stabilized, and released, this course of treatment should continue for a minimum of one year and longer if needed.  The real prognosis of this disorder is that Shonda will have to be on medicines for the rest of her life, along with psychosocial treatment, but with the introduction of these new treatments, it is possible for her to have more stability and symptom management.
