There are various treatment options for ASD that are proven to be effective. Interventions may be used independently or combined with other treatment methods. There's no singular treatment that's best to use. Often, a multimodal approach is used and tailored to the multifaceted needs of the client. Research and clinical experience has shown that when applying treatment, it can be harmful if not approached with individualization, care, and affirmation.
Neurodivergent-affirming care
Whichever treatment modality you apply, it's of utmost importance to provide it through the lens of neurodivergent-affirming care. There has been some pushback from the ASD community against efforts to train autistic people to conform to neurotypical norms — and against some aspects of applied behavior analysis. This can lead to emotional distress and “masking” themselves to fit in. In contrast, neurodivergent-affirming care embodies honoring individual needs and strengths, supporting autonomy and self-determination, honoring diverse communication and sensory profiles, challenging ableism and neuronormativity, and empowering individuals to thrive authentically. Treatment should always emphasize inclusion, respect, and validation of neurodivergent identities.
Applied behavior analysis (ABA)
Applied behavior analysis (ABA) is a cornerstone treatment that is widely applied to treat ASD. It focuses on the client’s behaviors, learning processes, and environment. The therapy attempts to positively reinforce new, helpful behaviors. Skills are taught, such as communication and social skills. Challenging behaviors are understood in context, and therapists use positive reinforcement to support the development and use of alternative, adaptive skills. ABA is proven to be most effective when applied from a very early age (between the ages of 2 and 6). There are play-based versions of ABA, such as the Early Start Denver Model (ESDM) and Pivotal Response Treatment (PRT). Other commonly used aspects of ABA are Discrete Trial Training (DTT) and Naturalistic Developmental Behavioral Interventions (NDBI). Skills can continue to be taught at older ages. There's no upper age limit to ABA, but the best results usually come from earlier treatment. ABA is based on individualized treatment plans and is data-driven through progress monitoring and ongoing plan adjustments.
Speech and language therapy
These treatment approaches are focused on improving the verbal, nonverbal, and social communication skills of the client. The goal is to help clients express themselves and interact with others more effectively. Visual cues, modeling, prompting, play-based social communication, oral-motor skills, sentence structure, speech rhythm, and enhanced vocabulary can all be part of this type of therapy. Sign language or voice-output device training may be taught to autistic clients who are non-verbal or minimally verbal. Similar to ABA, effects are best from early ages (18 months to 6 years) but can be beneficial at any age.
Occupational therapy
Occupational therapy (OT) helps clients develop skills that are necessary for daily life. These are things that help clients with home life, school life, or work life. It may include aspects of physical or sensory integration therapy. OT emphasizes daily living and fine motor skills development. All ages benefit from OT, but the earlier the better.
Sensory integration therapy
Sensory integration therapy, often part of occupational therapy, helps improve the responses to sensory stimuli. It helps individuals who are over- or under-reactive to sensory input, which can impact their motor skills, social interactions, attention, and daily functioning. This intervention is primarily used for children aged 3 to 12. It's often play-based therapy that focuses on sensory motor activities.
Cognitive behavioral therapy (CBT)
CBT is used to deal with the emotional challenges (such as anxiety and depression) that can occur for autistic clients. Clients develop insight through identifying the connection between thoughts, feelings, and behaviors. They can improve their mood and emotion regulation by shifting unhelpful thought patterns or participating in helpful behavioral strategies. This can help clients reframe how they think about and respond to various situations. CBT can be beneficial for all ages.
Educational interventions
These treatment approaches are applied in a school setting. They are tailored to the unique strengths, needs, and profile of the child with ASD. The goal is to help enhance learning of academic subjects, independence, and social skills. This occurs through applying positive reinforcement, visual cues, instruction, environmental adaptation, sensory support, and collaboration with other support team members. This approach starts as early as toddler age and can extend into early adulthood for clients remaining in educational settings.
