We aimed to use Tongue Acupuncture (TAC) to assess for any change in brain function.

Autism or Autistic Spectrum Disorder is a neurodevelopmental disorder affecting language, communication, social interaction and behavior. Autism is a heterogeneous disorder makes the assessment of treatment difficult. Only few measures have been used in a standardized way to document the outcome of different modalities of treatment in autism. Most claims of treatment effect in autism have been quite anecdotal. In Traditional Chinese acupuncture, nearly 400 acupoints on the body surface are interrelated to various functions. Acupuncture had been practiced in China for over 2 millennia. The surface acupoints are linked through 14 meridians to various organs or viscera of the human body. The approach in TCM, in sharp contrast to western medical concept, is a holistic approach with a more philosophical background of balancing the Yin-and-Yang. The main objective of TCM is to improve health of body and mind. The pathophysiological basis of TCM aimed to improve energy or body-flow \[de-qui in Chinese\]. Even a normal human subject will respond to acupuncture due to the flow of energy. The effect of acupuncture was hypothesized and proven in animal and human studies to be due to direct neural stimulation, changes in neurotransmitters such as endorphin, immunological markers and endocrinological signals. Thus, acupuncture is Thus, acupuncture is effective in chronic disorders, especially in neurological disorders. We had demonstrated clinical efficacy of acupuncturing the surface or base of the tongue in specific acupoints in improving various functional modalities in patients with chronic neurological disorders such as cerebral palsy, stroke and drooling problems. In our experience, TCM approach for autism is more holistic. Autism is postulated as part of the spectrum of lower intelligence. Thus, the approach to autism is considered as lower intelligence due to Heart-meridian and Kidney-meridian yin-yang imbalance resulting in communication problem and Liver-meridian yin-yang imbalance leading to behavioral problems. We attempted to use a different approach in looking at autism and to assess the efficacy of an innovative method in TCM in improving the functional status of these children. Specific acupoints in the tongue corresponding to various organs and meridians were used for autism. The organ and meridian concept in TCM model has been assumed as a fundamental basis to improve the behavior, cognition and communicative ability in children with autism. The objective is to study the efficacy of a short course of TAC in improving the overall functional status of autism.
