Movement disorder linked to common medications
An estimated 250,000 to 400,000 people in the United States suffer from Tardive Dyskinesia, a serious and disabling involuntary movement disorder. The condition was first linked to use of anti-psychotic medications but most recently has been linked to a common heartburn, GERD (gastroesophageal reflux disease) and gastroparesis medication known as Reglan (metoclopramide). How the medications cause Tardive Dyskinesia is debatable, but studies show that long-term use of medications leave users at higher risk of developing the condition.
