An autism spectrum disorder (ASD) can be challenging enough to deal with on its own, but often there are complications that add to the complexity of treatment programs, including conditions that a person may have in addition to an ASD.

Some of the disorders and other problems that tend to accompany ASDs include:

Sensory Problems

Someone with an ASD can be very sensitive to sensory input. It can be severe enough that common sensations can be discomforting or painful. Alternatively, they may not respond to extremes in heat, cold, or pain.


Seizures are a very common side effect of ASDs, and often begin in young autistic children or autistic teenagers.

Tuberous Sclerosis

This rare disorder causes benign tumors to grow in the organs, including the brain. The link between tuberous sclerosis and ASD is unclear. However, studies have shown that ASD rates are much higher among children with tuberous sclerosis than those without tuberous sclerosis.

Mental Retardation

Autistic children often have at least some level of mental impairment. This can include Fragile X syndrome, which is a problem with the X chromosome, and is a very common cause of mental retardation, particularly among males.

Other Complications

Other problems someone coping with an ASD can face include aggression, odd sleeping and eating habits, and problems with digestion.
