“For me as an actor, crying or laughing is a matter of choice. But I don’t have PBA. And if you’re someone who does, you may not have that control.”– Danny Glover
Uncontrollable crying or laughing can be caused
by a neurologic condition, PBA.
PBA may affect people with underlying conditions such as:
  • Stroke
  • Traumatic Brain Injury (TBI)
  • Alzheimer's disease or
    other dementias
  • Multiple Sclerosis (MS)
  • Lou Gehrig's Disease
    (ALS)
  • Parkinson's Disease
