It also shows that it is due to inappropriate sensory stimulations; and likewise that Autism and other mind disorders are due to inappropriate stimulations.  The author has developed a new theory on brain and mind development based on development via sensory stimulations and thus inappropriate sensory stimulations are capable of causing abnormal mind and brain developments.
