A neurological movement disorder affecting about 1% of the population. Incorrect signals from the brain cause muscles to contract and spasm involuntarily.
A rare neurological disorder often trigged by the seasonal flu shot. Dystonia has gotten recent attention in the media due to the 26 year old woman who is unable to walk forwards without stumbling and making jerking movements. She is unable to walk normal unless she is running...talk about a one in a million chance!
