Our diagnosis was hypomelanosis of Ito (HI); a rare type of neurocuteneous syndrome. Routine investigations were normal, CT scan of the brain showed mild cortical atrophy, EEG was normal. The parents were counseled about the recent level of intellectual functioning, asked to allow the child for learning self-help skills, and referred to a child development center, child psychologist, and speech therapist.
