Reading skills are likely to be well developed, but they often have great difficulty making inferences based upon reading. Weaknesses are most obvious in tactile perception, psychomotor coordination, visual-spatial organization, and situations that involve interpretation of social cues. One of the most difficult tasks in diagnosing Asperger's Disorder is to differentiate between this disorder and other conditions, specifically Attention Deficit Disorder and Anxiety Disorders. Intervention usually consists of different psychological strategies or medication. Both types of intervention deal with decreasing the symptoms that appear.
Medications are available to treat a variety of behaviors that are exhibited.
Psychiatric consultation is critical in making such a decision. The diagnosis of both Autistic Disorder and Asperger's Disorder is a complex task that is even more difficult when the child is severely visually impaired. Although the cause of PDD is not clearly established, PDD is often associated with congenital infections and structural abnormalities of the central nervous system. Both of these conditions are also often seen as causes of visual impairment. The diagnosis of any form of PDD is challenging.
