Delayed autism is an autism spectrum disorder (ASD) diagnosis that is given to individuals who do not show signs of autism until the age of two or later. This is in contrast to early autism or infantile autism, which is usually diagnosed before the age of two. Delayed autism is also known as regressive autism or late-onset autism. It typically affects individuals who are verbal and socially advanced, but then begin to experience regression in their development.
Symptoms of Delayed Autism
The symptoms of delayed autism vary depending on the individual but generally include:
• Difficulty with social interactions – Individuals may have difficulty with understanding social cues, responding to others, and engaging in conversations.
• Repetitive behaviors – Repetitive behaviors such as hand-flapping, rocking, and lining up objects are common.
• Sensory sensitivities – Some individuals may be overly sensitive to certain sights, sounds, smells, and textures.
• Difficulty with communication – Individuals may have difficulty understanding and expressing themselves verbally, as well as being able to understand what others are saying.
• Unusual behaviors – Unusual behaviors such as spinning, toe-walking, and echolalia (repeating words or phrases) may be present.
Diagnosing Delayed Autism
The diagnosis of delayed autism is based on a comprehensive evaluation by a medical professional. This evaluation typically includes a physical and neurological exam, developmental and medical history, and an assessment of the individual’s behavior.
Treatment of Delayed Autism
The treatment of delayed autism is individualized and depends on the needs of the individual. Generally, treatment may include:
• Behavioral interventions – Behavioral interventions such as Applied Behavior Analysis (ABA) can help individuals learn new skills and decrease challenging behaviors.
• Occupational therapy – Occupational therapy can help individuals with sensory sensitivities, fine motor skills, and daily living skills.
• Speech-language therapy – Speech-language therapy can help individuals with language and communication skills.
• Medication – Medication may be prescribed to address anxiety, depression, and other mental health concerns.
Delayed autism can be a difficult diagnosis for families to accept, but with the right support and intervention, individuals can live fulfilling and meaningful lives.
