Tic disorder and Tourette’s Syndrome are considered to be caused by imbalance of the TMJ, leading to subluxation of the upper cervical vertebrae as well as abnormality of the brain-nervous system.
Imbalance of the TMJ induces distortion of the Sphenoid bone, which in turn causes errors in the brain-nerve system including abnormality in the circulation of the cerebrospinal fluid. This then triggers abnormality in neurotransmitters, which will generate an interference signal that eventually gives rise to tics and/or Tourette’s Syndrome*.
*Tourette’s Syndrome is diagnosed when both motor and phonic tics are present for more than one year.
