Injuries: Degenerative diseases or head injuries are another reason for this condition. However, some experts believe that perinatal pathology results in savantism.

Hormones: It is understood that testosterone, male hormone accelerates brain growth with this syndrome in infants. It inhibits the oxytocin hormone production that successfully adapts in society. Moreover, it is assumed that the mutating neurons are also responsible for this syndrome.



However, the actual causes of this syndrome are still unclear and remain under assumptions. Experts believe that males are more prone to this syndrome as the neurophysiologists of America explains that the superiority of dozen genes of the chromosome X in males plays a vital role in a birth of an infant with this condition.
