Symptom #9: Tics and Tremors
A tic is a repetitive and nonrhythmic movement or vocalization. Tics are usually visible to observers. Some examples of tics include repetitive throat clearing and eye blinking. Tics should be distinguished from other movement disorders such as dystonia, myoclonus, and chorea.
A tremor is an involuntary muscle contraction and relaxation that is rhythmic. There is often twitching or oscillations of the affected body part. It is the most common of all involuntary movements and can affect the eyes, arms, hands, head, legs, and face. Tics and tremors can affect muscles that are supplied by nerves that are injured through trauma or disease.
