Not exactly: Tics can involve muscles in the head, face, arms, legs or any muscle group in the body. Facial tics are the most common. The cause of tics is unknown, but brain damage as from traumatic brain injury rarely cause tics. The cause is usually genetic, but there is evidence that tics may also arise as a consequence of certain infections such as strep.
