The aim of the present study was to investigate the potential predictive value of early self‐experienced neuropsychological deficits for the subsequent development of schizophrenia. A total of 96 patients with DSM‐III‐R diagnoses of personality disorders (formerly called ‘neurotic disorders’) who had been examined for the presence of such subjective experiences of deficits with standardized instruments were re‐examined for the possible development of schizophrenic symptoms. After an average follow‐up period of about 8 years, more than 50% of the patients had developed schizophrenia according to DSM‐III‐R criteria. In 77% of cases the outcome ‘schizophrenia vs. no schizophrenia’ was correctly predicted by the earlier presence or absence of self‐experienced disturbances of thought, speech, memory, perception and action. These findings suggest that certain self‐experienced neuropsychological deficits are able to indicate susceptibility to psychosis.
