[Cognitive functions in severe psychotic disorders]. / Kognitiiviset toiminnot vaikeissa psykoottisissa häiriöissä.

ABSTRACT

Cognitive functions in schizophrenia exhibit a widely mixed nature. A specific neuropsychological core disturbance typical of schizophrenia still remains to be defined. Disturbances of cognitive function that do not qualitatively differ from those associated with schizophrenia are observed also in other severe psychotic disorders. Cognitive disturbances may even be more significant than other symptoms of disease for the patient's overall condition and coping with daily life. Neuropsychological examination is an essential part of assessment of the total care and rehabilitation of a patient with psychosis.
