Pathological laughter and crying

Inappropriate involuntary laughing and crying due to a nervous system disorder.


Pseudobulbar affect is characterized by an involuntary and uncontrollable reaction of laughter or crying that's disproportionate to an event.


The crying or laughing may start as a response to a situation, such as a sad movie, but the feelings are more intense and last longer than expected. They are difficult or impossible to stop.


Antidepressants and talk therapy can help.
