Emotional Lability

Emotional lability is described as a sudden change in response to events or phrases that others might find only mildly arousing. It causes sudden and unpredictable episodes of crying, laughing or other emotional displays.

Epilepsy

Epilepsy occurs as a result of abnormal electrical activity originating from neurons in the brain. Brain cells communicate by sending electrical signals in an orderly pattern. In epilepsy, these electrical signals become abnormal, giving rise to an "electrical storm" that produces seizures. Epilepsy is a relatively common condition in the U.S. and about 2.5 million people have epilepsy. In fact, about 9 percent of Americans will have at least one seizure during their lives.
