Attention in patients with chronic schizophrenia:
Deficit in inhibitory control and positive symptoms
ABSTRACT – Background and Objectives: Attention is a central mechanism controlling
information processing, activating and inhibiting processes, and forming a complex sys-
tem including diferent networks in specific areas of the brain1. To correctly assess the role
of attention in schizophrenia it is necessary to discriminate its different attentional com-
ponents, which may by selectively altered. Attention span, focused attention, selective at-
tention, sustained attention and inhibitory response, were assessed in patients with chron-
ic schizophrenia and healthy matched controls.
