Twitches are small muscle spasms that may be normal, or may indicate tics or other seizure type disorders. Occasional twitches are normal and not a disorder. Twitches also need to be distinguished from tremor or shakiness, which has both normal and disease causes. One particular type of twitching that is normal is sudden twitches right at the onset of sleep. When twitching is abnormal, it may indicate a Tic Disorder (e.g. Tourette Syndrome), fasciculations, or other type of Convulsive Disorder.
