Biological Treatments for Autism Spectrum Disorder: An Overview

Biological treatments for ASD target underlying biological imbalances. They must be individualized and medically supervised.

1. Medications

• Antipsychotics (risperidone, aripiprazole, olanzapine, quetiapine): reduce irritability, aggression, hyperactivity, stereotypies.
• Stimulants (methylphenidate, amphetamines): improve attention, reduce hyperactivity/impulsivity.
• SSRIs (fluoxetine, sertraline): address comorbid anxiety/depression.
• Alpha-2 agonists (clonidine, guanfacine): reduce hyperactivity/impulsivity.

2. Dietary Interventions

• Gluten-free/casein-free (GFCF): Some report behavioral improvements; evidence mixed.
• Ketogenic diet: Low-carb, high-fat; may reduce seizures, improve cognition in some.
• Supplements: Omega-3, probiotics, vitamin D—more research needed.

3. Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) shows preliminary benefits for social behavior/communication; rigorous research lacking.

4. Transcranial Magnetic Stimulation (TMS)

Non-invasive brain stimulation; early promise for social cognition/communication; still experimental.

All biological treatments require careful consideration, monitoring, and individualization by healthcare professionals.
