Pervasive Developmental Disorder (Not Otherwise Specified)


Recent studies state that the number of people with all forms of autism cannot be precisely fixed, but it appears to be around 1 in 100 people. We do not know how many of these have Pervasive Developmental Disorder - Not Otherwise Specified.

PDD - NOS is present from birth, although the symptoms may not be immediately obvious. It is four times more common in boys than in girls.
