IEED or Pseudobulbar Affect is typically related to mood swings. It really has nothing to do with speech patterns or word recall. People who are experiencing IEED often may go from hysterically crying one moment to laughing hysterically the next. They also may have abnormal reactions to things, i.e. bursting out laughing in the midst of a funeral. This is more typically seen in patients who have suffered strokes in certain areas of the brain as well as some patients with MS, ALS, Alzheimer's and Traumatic Brain Injuries.
