Pseudobulbar affect

Pseudobulbar affect (PBA), also called emotional incontinence, is a neurological disorder involving brief, intense, uncontrollable episodes of crying or laughing. Episodes can be triggered by trivial or neutral stimuli and may not match a person's emotional state. PBA results from another neurological disorder or brain injury and differs from mood disorders because it disrupts momentary emotional expression rather than causing persistent disturbance.
