pseudobulbar affect
Pronunciation: SUE-doe-BUL-bar
Neurological condition characterized by sudden, uncontrollable episodes of laughing or crying that are disproportionate to or independent of the patient's actual emotional state.
Full Definition
Pseudobulbar affect (PBA) is a neurological disorder resulting from damage to brain pathways that control emotional expression, commonly seen in stroke, traumatic brain injury, and neurodegenerative diseases. Unlike depression or mania, the emotional outbursts do not reflect the patient's true feelings and often cause significant distress. The condition involves dysfunction of the corticobulbar and corticospinal pathways that normally regulate emotional motor responses. Documentation requires careful distinction from psychiatric mood disorders.
Usage
Usage note: Always lowercase except when abbreviated as PBA. Not hyphenated.
