Cognitive deficits constitute a core symptom in schizophrenia, are difficult to treat, and have special relevance regarding prognosis and functional outcome. The search for pharmacological strategies for improving cognition in schizophrenic patients has been hindered by the lack of a consensus regarding instruments for cognitive assessment. The 'Measurement and Treatment Research to Improve Cognition in Schizophrenia' (MATRICS) initiative of the U.S. National Institute of Mental Health (NIMH) set the development of a consensus cognitive battery as one of its objectives. In a first phase, the seven cognitive domains which have been shown to be impaired in schizophrenia and that were to be assessed were identified: Speed of processing, Attention/Vigilance, Working memory, Verbal learning, Visual learning, Reasoning and problem solving, and Social cognition. In a second phase, the MATRICS Consensus Cognitive Battery (MCCB) was developed. This is a cognitive assessment battery composed of ten instruments, which assess the seven domains in a little over one hour. The MCCB has been standardized in U.S. population, and the Spanish standardization has been recently published.

A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.
Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.
A direct form of psychotherapy based on the interpretation of situations (cognitive structure of experiences) that determine how an individual feels and behaves. It is based on the premise that cognition, the process of acquiring knowledge and forming beliefs, is a primary determinant of mood and behavior. The therapy uses behavioral and verbal techniques to identify and correct negative thinking that is at the root of the aberrant behavior.
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.
