pseudobulbar affect
Pronunciation: SOO-doe-BUL-bar
Neurological condition causing involuntary, inappropriate emotional outbursts disconnected from actual feelings.
Full Definition
A neurological condition characterized by sudden, frequent, and uncontrollable episodes of laughing or crying that are disproportionate to or disconnected from the patient's actual emotional state. Also known as emotional incontinence or pathological laughing and crying, pseudobulbar affect results from damage to neural pathways that control emotional expression, commonly occurring in conditions such as traumatic brain injury, stroke, multiple sclerosis, and neurodegenerative diseases. The emotional displays are involuntary and often distressing to patients, who retain awareness that their expressions don't match their feelings. This condition significantly impacts quality of life and social functioning.
Usage
Usage note: Distinguish from mood disorders; patients with PBA have intact emotional awareness despite involuntary expression.
