Pathogenetic and therapeutic perspectives on neurocognitive models in psychiatry: A synthesis of behavioral, brain imaging, and biological studies

Abstract

Neurocognitive assessments are useful to determine the locus of insult as well as functional capacities of patients on treatment. In psychiatry, neurocognitive assessment is useful in the identification of brain lesions, evaluation of cognitive deterioration over time, and advancement of theories regarding the neuroanatomical localization of symptoms. Neurocognitive models provide a bridging link between brain pathology and phenomenology. They provide a useful framework to understand the pathogenesis of psychiatric disorders, bringing together isolated findings in behavioral, neuroimaging, and other neurobiological studies. This review will discuss neurocognitive model of three disorders – schizophrenia, bipolar disorder, and obsessive compulsive disorder – by incorporating findings from neurocognitive, neuroimaging, and other biological studies.

“…1 and 2) [43][44][45]47]. An important number of evidences showed neurophysiological and neuropsychological disturbances in schizophrenia [73][74][75]. However, visual perception disturbances are recognized in recent studies as a valid way to study information processing deficits in schizophrenia [49,76,77].…”

Psychiatrists need a Freud-chip in their psyche to be well-rounded

“…Hence, while a synthesis of the behavioral, biological, and brain imaging, which is being attempted by many investigators all over the world,[13] is certainly a brave venture, it is not likely to yield satisfactory results. Bridging brain pathology and phenomenology is a great dream but indeed quite a distant one.…”
