These might include things as simple as turning up the TV to drown out the voices they were hearing! A. The reason for this is because the approach does not consider other factors such as genes. Very important to note genetics are only partly responsible, otherwise identical twins would have 100% concordance rates. Weak evidence for family based explanations, there is no evidence that supports the importance of double bind theory. Metaanalysis by Crossley Et Al (2010) suggested that Atypical antipsychotics are no more effective, but do have less side effects. This helps improve the quality of life for schizophrenia sufferers. Family therapy is based on the premise that nurture (upbringing) is a significant factor in schizophrenia.

They believed that schizophrenia was a result of social pressures from life. DSM) should arrive at the same diagnosis for the same individual. For example, an excess of dopamine receptors in Brocas area might be responsible for poverty of speech and auditory hallucinations.

First, cognitive deficits which are impairments in thought processes such as perception, memory and attention. These may be risk factors for the development and maintenance of schizophrenia.
