Labile Affect

Labile Affect, also known as Pseudobulbar affect (PBA) or Emotional Incontinence, is a disorder where the patient has excessive displays of emotion, or expresses emotions that are not congruent with the situation. For example, uncontrollable crying over trivial things like accidentally knocking over a glass of water, or laughing hysterically over sad news like hearing about a devastating calamity. This condition results from an underlying neurological disorder, or from brain injury.
