Is visual/spatial impairment absolute criteria for Asperger's?

Question

Please give me reference material.

Answer 1

No, it shouldn't be. This is a link to the criteria in the DSM, which is used by psychologists and psychiatrists to diagnose Aspergers.

The essential features of Asperger's Disorder are:

Criterion A. Severe and sustained impairment in social interaction

Criterion B. The development of restricted, repetitive patterns of
behaviour, interests, and activities

Criterion C. The disturbance must cause clinically significant impairment in social, occupational, or other important areas of
functioning.

Criterion D. In contrast to Autistic Disorder, there are no clinically
significant delays in language (eg: single words are used
by age 2 years, communicative phrases are used by age 3
years).

Criterion E. There are no clinically significant delays in cognitive
development or in the development of age-appropriate
self-help skills, adaptive behaviour (other than in social
interaction), and curiosity about the environment in
childhood.

Criterion F. The diagnosis is not given if the criteria are met
for any other specific Pervasive Developmental Disorder or
for Schizophrenia.
