Tourette's Syndrome is frequently misdiagnosed and undiagnosed because it's symptoms can vary greatly and may also be associated with other conditions such as attention deficit hyperactivity disorder, obsessive-compulsive disorder, learning disabilities, anxiety, mood disorder or sleeping disorders. Current studies estimate the prevalence of chronic tics to be 1 in 100 people. Males face a four fold greater risk than females and the condition is often hereditary. Simple ‘phonic' tics can include chronic smiffing, grunting, throat clearing, clicking and screaming whereas complex phonic tics may include stuttering, repetition of words and saying socially unacceptable words. Simple motor tics can present as eye blinking, nose wrinkling, jaw thrusting, shoulder shrugging, neck jerking and complex motor tics can include jumping, touching, twirling when walking, retracing steps, imitating other's movements or making obscene gestures for no reason. When sufferers attempt to suppress their symptoms, they often become more frequent and intense. An experimental treatment involves deep brain stimulation through electrode placement in portion of brain that controls movement. Some tics can be treated through medications such as Tenex, Haldol and Klonopin or injection of botox into the affected muscle which can prevent the tic for several months.
