Definition of Autistic behavior:

Autistic behavior describes behavioral patterns similar to those seen in autism.

Considerations:

Autistic behavior includes:

• Abnormal socialization (lack of need for interacting with others)
• Abnormal speech patterns
• Absent or poorly-developed verbal and nonverbal communication skills (inability to clearly express thoughts and needs)
• Social withdrawal
• Inability to make friends
• Repetitive body movements
• Ritualistic behavior
• Lack of eye contact

Several infections and nervous system (neurological) diseases can produce symptoms like those of autism.

Common Causes:

• Deafness
• Infantile autism
• Mental retardation
• Metabolic degenerative CNS (central nervous system) disorders
• Schizophrenia
