Paranoid Schizophrenia ✔✔Involves delusions but the patient stays emotionally responsive. They can show more argumentative behaviour and are much more alert. Undifferentiated Schizophrenia ✔✔Includes patients that clearly don't belong within any other type of schizophrenia category. They display symptoms but do not fit in with other types. Residual Schizophrenia ✔✔People who have had an episode of schizophrenia in the last 6 months and show some symptoms but these are not as strong. Co-Morbidity ✔✔The presence of one or more additional disorders that occur simultaneously with schizophrenia. This could suggest that schizophrenia is not a separate disorder. Culture Bias ✔✔The tendency to over-diagnose members of other cultures and claiming them to be suffering from schizophrenia. Gender Bias ✔✔The tendency for diagnostic criteria to be applied differently to males and females so there are differences in the classification of the disorder. Symptom Overlap ✔✔The perception that symptoms of schizophrenia are symptoms of other mental disorders. Biological Explanations ✔✔These focus on the possible effects that genetics, dopamine and neural correlates have on schizophrenia. Genetic Explanation ✔✔Transmission of abnormality by hereditary means. Dopamine Hypothesis ✔✔The development of schizophrenia is related to abnormal levels of the hormone and neurotransmitter dopamine. Neural Correlates ✔✔The idea that the development of schizophrenia is related to structural and functional brain abnormalities. fMRI helps to provide a comparison of the brains of schizophrenics and non-sufferers. Psychological Explanations for Schizophrenia ✔✔These include family dysfunction, cognitive explanations and dysfunctional thought processing. Family Dysfunction ✔✔The idea that dysfunctional family relationships are related to the development of schizophrenia. Stress and contradictory situations can influence schizophrenia. Cognitive Explanations ✔✔The idea that the development of schizophrenia is due to maladaptive thought processes which involve a complex interaction of different factors. They may experience positive or negative symptoms. Dysfunctional Thought Processing ✔✔The idea that the development of schizophrenia is related to abnormal ways of thinking. Some schizophrenics may believe that there ability to use metacognition are the voices of others in their heads. Drug Therapies ✔✔Treatment using chemical tablets and other means for abnormality. Antipsychotic Drugs ✔✔These were introduced in 1952 and helped to dampen the symptoms of schizophrenia so that an individual can function normally. Typical Antipsychotics ✔✔These were the original first-generation drugs that were created in the 1950s. Atypical Antipsychotics ✔✔Second-generation drugs produced after typical antipsychotics to treat schizophrenia. They have less side effects and are more effective. Cognitive Behavioural Therapy ✔✔A psychological treatment used for schizophrenia by modifying thought patterns to alter behavioural and emotional states. Family Therapy ✔✔A form of therapy based upon the psychological explanation of family dysfunction. It attempts to alter the communication systems within families. It involves the whole family and not just the schizophrenic to work. Token Economies ✔✔A method of behaviour modification that reinforces target behaviours by awarding tokens that can be exchanged for material goods. They are used particularly for negative symptoms. Interactionist Approach ✔✔The idea that schizophrenia develops as a result of psychological, biological and social factors. Diathesis-Stress Model ✔✔The idea that individuals have varying genetic potentials combined with environmental factors. The idea was proposed by interactionists. Interactionists Treatments ✔✔Although these can be expensive and take time, combining treatments are more effective in curing schizophrenia. Antipsychotic drugs are usually given before to reduce symptoms then psychological treatments are carried out. [Show More]
