dysexecutive syndrome
A constellation of cognitive and behavioral symptoms resulting from executive function deficits.
Full Definition
Dysexecutive syndrome encompasses a range of cognitive, emotional, and behavioral symptoms that occur following damage to the prefrontal cortex and its connections. Characteristic features include impaired planning and organization, poor impulse control, difficulty with abstract thinking, reduced cognitive flexibility, and problems with self-monitoring and regulation. This syndrome significantly impacts daily functioning and is commonly observed following traumatic brain injury, stroke, or neurodegenerative diseases affecting frontal-subcortical circuits.
