Pseudobulbar affect (PBA) is a form of emotional liability that causes sudden, inappropriate, uncontrollable laughing or crying which does not usually reflect the person's mood. It is sometimes referred to as involuntary emotional expression, emotional incontinence, or uncontrollable laughing and crying. PBA is a neurological disorder that is often mistaken for depression.
Causes[edit | edit source]
Pseudobulbar affect is typically caused by neurological diseases or injuries including multiple sclerosis, stroke, amyotrophic lateral sclerosis (ALS), traumatic brain injury (a head injury causing loss of consciousness), or Parkinson's disease. The emotional outbursts caused by PBA may last up to several minutes, and are different from how the person would normally have responded, and may occur in response to even mild or neutral stimuli. Crying is more common than laughing, and laughing may turn into crying.
