Would Nanoparticles Give Hope for the Treatment of Autism Spectrum Disorder?

Autism spectrum disorder (ASD) presents lifelong neurodevelopmental challenges and is diagnosed in early childhood. ASD is complex, has multiple causes, and is characterized by communication difficulties, impaired social interaction, and repetitive behaviors. Unfortunately, there are no specific biomarkers for diagnosis or effective treatments yet. However, nanomedicine offers promise for treating central nervous system (CNS) disorders conditions, including ASD. Nanomaterials can cross the blood–brain barrier, target specific cells, disseminate in brain tissue, and serve as carriers for therapeutics. This review emphasizes the importance and potential of nanomedicine, current pharmacological treatments for ASD, challenges in drug development, and recent medical approaches based on nanotechnology to overcome the blood brain barrier and deliver CNS therapeutics. Neurobiological research for future nanomedicine applications will also be highlighted.
