PSYC33H3 Chapter 5a: Neurohabilitation of Executive Functions
Document Summary
Executive functions: integrative processes that guide goal-directed and purposeful behavior in everyday life: executive dysfunction predict poorer rehabilitation outcomes and lower level of functional independence following brain injury. And more rapid decline in health status in older adulthood. Few empirical validated interventions exist to treat: lack of training target, insensitive measures, and generalizations to real life are barriers. Evidence of critical role of frontal lobes and frontal-subcortical circuits in executive functioning: monitoring and manipulating diverse cognitive processes. Executive control functioning characterized as emergent property of interactions among large-scale cortical brain networks. Some neurological disorders preferentially damage frontal lobe structures or. Np test insensitive to executive function deficits, clinical presentation of axonal pathway subserving frontally mediated networks patients with these disorders almost always includes evidence of executive. Executive dysfunction associated with range of deficits = dysexecutive function deficits syndrome. Inability to initiate, stop, and modify behavior in response to changing stimuli.
