  • Positive symptoms include delusions, hallucinations and disorganized behaviours.
  • Negative symptoms include lessened emotional expressions, lack of motivation and limited emotions.
  • The types of schizophrenia are based on symptomology at the time of diagnosis or that were more frequently observed. Positive symptoms dominate in the paranoid type and is the most common of all sub types. The disorganized type is more socially disrupting, with greater emotional and behavioural disturbances. An undifferentiated schizophrenia diagnosis indicated that there are no specific symptoms indicated.
  • Thereis a large amount of research, including drug trials, which support the dopamine theory.Those diagnosed have been found to have a higher concentrations of Dopamine. Genetics are thought to play a large part in the prevalence of schizophrenia, 47 percent chance of an identical twin of a sibling diagnosed with schizophrenia. developing the disorder. Non-identicaltwins have a 12 percent likelihood, which is the same chance as achild with one parent who has schizophrenia. The brain structure of those diagnosed with schizophrenia are also markedly different to those without the disorder, with scans of the brain showing a much smaller brain volume of those with schizophrenia.
  • Psychological views have arisen primarily from cognitive and psychodynamic perspectives. It has been previously thought that a child with overprotective, un-nurturing and inconsistent parents are more likely to develop schizophrenia.The psychological theory has mostly been unproven, with more of evidence pointing to biological factors. The cognitive theory asserts that hallucinations are misinterpreted, leading to delusions, causing withdrawal from the social environment. There is little evidence to support these theories.
  • Bbrain research has shown that the social and emotional environment during their development has a enduring impact on brain development, which includes cells and genes.
  • Marijuana, amphetamines, alcohol all contribute to the development of schizophrenia. It is also more likely that those with schizophrenia abuse alcohol and drugs as a coping mechanism.
  • It has been found that between one thirds and two thirds of people with schizophrenia currently live with their families.Carers are directly impacted emotionally and financially when the person they are caring for is hospitalized or relapse for long periods of time. Families experience frustration whilst ensuring that medication is taken. They are required to cope with inappropriate behaviours and the need to frequently supervise. This leads to fatigue and anxiety, which becomes a burden in itself.
  • It is believed that the treatment of schizophrenia shouldinclude a range of facilitations which are symptom specific and include the social and learning needs of the individual and their families.
