Tourette syndrome (TS) is a common, genetic disorder whose primary manifestations are the presence of motor tics. There are, however, many associated features such as obsessive-compulsive behaviors, short attention span, hyperactivity, learning disabilities, dyslexia, short temper, discipline problems, stuttering, multiple phobias, anxiety attacks, depression, wide mood swings, inappropriate sexual behaviors, and problems with normal socialization.
