Abstract
Summary: The neurological deficits in sensory and motor function in schizophrenia have been described using a confusing variety of terms, reflecting their uncertain relevance and significance to psychosis. In this article we explore the nature of neurological abnormalities in psychosis, describe their assessment and suggest their potential relevance for clinician and patient. We propose that the assessment of neurological abnormalities and extrapyramidal side-effects should figure in the assessment of any patient with psychosis, particularly at illness onset. Furthermore, we suggest that neurological abnormalities can inform prognostic predictions and help to identify patients with more complex future care needs.
