Discovery of genetic cause and drug therapy for ADHD, autism and 22q that will allow patients to control their symptoms for these three diseases is described. The discovery is by Hakon Hakonarson, MD, Ph.D. who, in 2015, found the genetic cause for the three diseases. He then conducted a clinical trial to prove that the drug NFC-1 could regulate and modulate the genetic mutation that caused the diseases. This is an example of precision medicine being applied to treat the ADHD, autism and 22q patients. The Neighborhood Drug Company (three couples who are neighbors and friends) was instrumental in the success of the company and the development of the therapy for the three diseases.
