Autism Symptoms

Most parents of autistic children suspect that something is wrong by the time the child is 18 months old and seek help by the time the child is age 2. Children with autism typically have difficulties in:

• Pretend play
• Social interactions
• Verbal and nonverbal communication

Some children with autism appear normal before age 1 or 2 and then suddenly "regress" and lose language or social skills they had previously gained. This is called the regressive type of autism.

People with autism may:

• Be overly sensitive in sight, hearing, touch, smell, or taste (for example, they may refuse to wear "itchy" clothes and become distressed if they are forced to wear the clothes)
• Have unusual distress when routines are changed
• Perform repeated body movements
• Show unusual attachments to objects

The symptoms may vary from moderate to severe.

Communication problems may include:

• Cannot start or maintain a social conversation
• Communicates with gestures instead of words
• Develops language slowly or not at all
• Does not adjust gaze to look at objects that others are looking at
• Does not refer to self correctly (for example, says "you want water" when the child means "I want water")
• Does not point to direct others' attention to objects (occurs in the first 14 months of life)
• Repeats words or memorized passages, such as commercials

Social interaction:

• Does not make friends
• Does not play interactive games

• Has heightened or low senses of sight, hearing, touch, smell, or taste
• May find normal noises painful and hold hands over ears
