The results suggest that the development of psychotic symptoms is preceded by a decline in IQ and memory. This may reflect a general and a more specific disease process respectively.

No abstract

Cannabis use, use of other illicit substances and upsetting life events may all lead to psychotic symptoms in vulnerable young people.

The lack of associations with psychotic symptoms and genetic liability to schizophrenia suggests that soft signs and physical anomalies are nonspecific markers of developmental deviance that are not mediated by the gene(s) for schizophrenia.

Aims and MethodWe undertook a postal questionnaire survey of all consultant psychiatrists working in Scotland to examine whether psychiatrists themselves may contribute to the misunderstandings surrounding schizophrenia by avoiding discussion of the diagnosis with their patients.ResultsTwo-hundred and forty-six (76%) responded. Ninety-five per cent thought the consultant psychiatrist was the most appropriate person to tell a patient their diagnosis of schizophrenia, although only 59% reported doing so in the first established episode of schizophrenia, rising to 89% for recurrent schizophrenia. Fifteen per cent would not use the term ‘schizophrenia’ and a variety of confusing terminology was reported. Over 95% reported telling patients they had mood disorders or anxiety, under 50% that they had dementia or personality disorders.Clinical ImplicationGreater openness by psychiatrists about the diagnosis of schizophrenia may be an essential first step in reducing stigma.
