PBA is also known by these other terms: involuntary emotional expression disorder (IEED), emotional liability, emotional incontinence, and pathological laughing and crying. It is associated with neurologic disorders that may include, but are not limited to MS, amyotrophic lateral sclerosis, dementias (including Alzheimer's disease), Parkinson's disease, stroke, and traumatic brain injury. It is estimated that about 10 percent of people with MS suffer from PBA, but because the condition is easily overlooked or misdiagnosed, the number of cases may be much higher.
