Sometimes the loss of skills is persistently progressive (especially if there is an underlying progressive neurological condition), but more often, the decline over some months and then a slight improvement. The prognosis is usually abysmal, and it leaves most individuals with severe intellectual disability. There is uncertainty about the extent to which this condition differs from autism. Sometimes, th
