A neurological or psychiatric symptom manifested by sudden and uncontrollable episodes of crying, laughing, or other emotional reactions that are disproportionate or unrelated to the person’s actual experiences. Such episodes usually occur involuntarily and may be triggered by minimal or no emotional stimuli. Emotional incontinence often develops as a result of damage or disruption to the parts of the brain responsible for regulating emotions, such as after stroke, traumatic brain injury, multiple sclerosis, amyotrophic lateral sclerosis (ALS), and other neurodegenerative diseases.
