As a child, Dr. Michael Wigler was fascinated by the personality of a friend's brother, "a very bright kid" who "never looked you in the face, constantly was throwing his arms up ... as though he had made some great discovery, and knew everything about baseball statistics." The eccentric boy, who Wigler later realized had Asperger's syndrome
, grew up to be a successful DJ. Wigler, meanwhile, grew up to be one of the world's foremost experts on the genetic basis of autism-spectrum disorders. He explains his trailblazing research, which he's gathered into a "unified theory of autism
," in his Big Think interview
As Wigler and his research team have discovered, the causes of autism are more complex than genetic inheritance on the one hand or spontaneous genetic mutation on the other. Instead, their studies suggest that both
factors can be at play, with some families affected by the first and others by the second. At the same time, Wigler says he has encountered zero evidence that vaccines or other environmental factors can trigger autism
in infants, though he sympathizes deeply with parents who seek external causes when babies they assumed were healthy seem to "regress" into cognitive dysfunction.
Fortunately, the work coming out of Dr. Wigler's lab holds hope for autism sufferers, promising both earlier diagnosis and improved treatment. He estimates that the "culprit genes" behind autism will take an additional two to four years to identify, after which testing for new potential treatments can begin immediately. Wigler, whose autism work emerged from his research into genetic causes of cancer, also identifies some revolutionary cancer solutions on the horizon
—including a simple screening test that may soon become a routine part of doctor's appointments.
