Full Definition
Pseudobulbar affect (PBA) is a neurological condition resulting from brain injury or neurological disease that causes involuntary, sudden, and frequent episodes of crying or laughing. These episodes are often disproportionate to or inconsistent with the patient's actual emotional state. PBA commonly occurs in patients with traumatic brain injury, stroke, multiple sclerosis, ALS, and dementia. The condition significantly impacts quality of life and can be mistaken for depression or other mood disorders.
Usage
