Autism Spectrum Disorders (Autism/ASD)

Autism Spectrum Disorders (Autism/ASD)

Home /Treatments

Growing evidence shows that regenerative medicine and stem cells may offer a promising new approach to treating autism spectrum disorders (ASDs).

Communication and social behavior disorders and repetitive behaviors characterize ASDs. Although their pathophysiology is unclear, evidence suggests that immune system dysfunction and neuroinflammation begin in the prenatal period and cause neurodevelopmental damage (1).

Regenerative medicine is a new field that uses the body’s cells to repair and regenerate tissue. Stem cells are a type of cell that can divide and turn into other types of cells. They can self-renew, which means they can make copies of themselves. Through the targeted application of stem cells at the point of treatment, the stem cells can differentiate into beneficial, regenerative cells.

Stem cells have anti-inflammatory, neuromodulatory, and neuro-regenerative properties. These properties make stem cells potential candidates for the treatment of ASDs.

Several clinical trials are underway to test stem cell therapy’s safety and efficacy for ASDs. Early results are promising, but additional research is needed.

If you or your child has an ASD, talk to your doctor about the possibility of using regenerative medicine and stem cells for treatment.

Benefits both in biochemical markers of neuroinflammation and in scales measuring the severity of ASD symptoms (including those related to language, social communication, repetitive behavior, and hyperactivity) have been found in patients aged 2 and 15 years followed up for up to 18-21 months, none of the studies reporting undesirable severe effects related to the intervention (2-6).
