abulia
Pronunciation: ah-BOO-lee-ah
Marked reduction in spontaneous speech, movement, and initiative, often seen in frontal lobe lesions.
Full Definition
Abulia represents a neuropsychiatric syndrome characterized by profound apathy, lack of initiative, and reduced spontaneous behavior. It differs from depression in that patients retain emotional responsiveness when stimulated. The condition commonly results from damage to the frontal cortex, anterior cingulate, or basal ganglia circuits. In clinical documentation, abulia should be distinguished from simple fatigue or depression, as it has specific anatomical correlates and treatment implications.
Usage
Usage note: Distinguish from akinetic mutism, which involves more severe motor and verbal reduction.
