Sik-Kee Au TCM Brain Theory™ explains why a healthy brain is essential in restoring the body’s systems to normal from disorders and illnesses such as ADHD and ASD
According to the Sik-Kee Au TCM Brain Theory™, the blockage or reduced blood flow and damage of the interconnecting central nervous system, endocrine system and blood circulatory system disrupt the production of hormones and the transmission of neurotransmitters, such as melatonin, dopamine and norepinephrine, leading to a defective encoding and decoding of functions and resulting in deficient or abnormal social behaviors that are the hallmarks of ADHD and ASD
