The schizophrenia syndrome is clinically characterized by abnormal constructions of meaning during comprehension (delusions), perception (hallucinations), action (disorganized and non-goal-directed behavior) and language production (thought disorder).

متن کاملDisturbances in the spontaneous attribution of social meaning in schizophrenia.
BACKGROUND Schizophrenia patients show disturbances on a range of tasks that assess mentalizing or 'Theory of Mind' (ToM).

METHOD To address these limitations, 55 clinically stable...

Cerebral metabolic hypofrontality in schizophrenia is a controversial research finding. In this article we discuss some of the issues that fuel this controversy, and we speculate on the neural mechanisms that may be responsible for the finding. Most regional cerebral blood flow (rCBF) studies using radioactive xenon have found hypofrontality; the results of positron emission tomography (PET) st...

Although less consistent, there is considerable evidence of more neurological signs in schiz...
