Diagnosis Criteria for Adults

Impairment in social communication and social interaction: Adults must demonstrate difficulties in understanding and using non-verbal communication, and difficulties in developing and maintaining relationships.
Restricted, repetitive patterns of behavior, interests, or activities: Adults must demonstrate restricted and repetitive patterns of behavior, interests, and activities, such as intense interests in specific topics, and insistence on sameness in routine activities.
Significant impairment: Adults must demonstrate significant impairment in one or more areas of life, such as difficulty in finding or keeping employment, or difficulty in establishing and maintaining relationships.
Diagnostic Evaluation
A diagnosis of ASD in adults is made through a comprehensive evaluation process. The evaluation involves a thorough medical history, physical exam, and psychological tests. The evaluation may also include an assessment of communication skills, language ability, learning abilities, and adaptive functioning.
Treatment for ASD in Adults
Once a diagnosis of ASD is made in an adult, treatment may include therapy, medications, and lifestyle changes. Therapy may include cognitive-behavioral therapy, speech therapy, occupational therapy, and social skills training. Medications may include antidepressants, antipsychotics, and mood stabilizers. Lifestyle changes may include increased physical activity, improved sleep hygiene, and healthy eating habits.
In conclusion, it is possible to be diagnosed with autism at age 30 or beyond. A comprehensive diagnostic evaluation is necessary to accurately diagnose ASD in adults. Once a diagnosis is made, treatment options may include therapy, medications, and lifestyle modifications.
