Tourette’s Syndrome – Risk Factors, Complications, and Treatment.


Tourette’s syndrome is a nervous system problem with tics like vocalization (vocal tic) and repetitive movements of muscles (motor tic). In particular, a person may frequently blink their eyes, babble offensive words, blurts out unusual sounds. Tics generally appears in kids between 2 – 15 years old, mostly in males than in females. The tics can get milder and fade away when kids step into adulthood. Parents can help their children to cope up with the conditions until they reach adulthood.

There are two types of tics associated with the Tourette’s syndrome.

  1. Vocal tics. Involuntary sniffing or humming and repeated throat clearing
  2. Motor tics. Unfortunate uncontrollable movements such as disgusted facial expression, shoulder shrugging, head jerking, and extreme eye blinking.

Again those two tics can be classified as follows:

  • Simple vocal tics are throat clearing and grunting.
  • Complex vocal tics: Unconditional use of offensive words, calling out, and imitating other people words.
  • Simple motor tics: Usually simple motor tics involve a single group of muscle which does eye blinking and grimacing.
  • Complex motor tics: This type involves more than one group of muscles which do series of movements like head banging, touching their own body part or another repeatedly. In rare cases, a person with Tourette’s syndrome may hurt themselves.

  • In a patient with Tourette’s syndrome, a temporary problem in basal ganglia cells disrupts the process of decision making.
  • The conditions of Tourette syndrome are hereditary and the mutation of a gene named SLITRK1 affects the normal brain development then it triggers the symptoms of Tourette’s syndrome.
  • Childhood infection – Streptococcal infection during childhood may be linked to the Tourette’s syndrome. This is referred to as Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal (PANDAS) infections. During the course of infection, antibodies produced by the immune system may interact with brain tissue and it affects the brain functions.
