Neuroplasticity-based novel brain stimulation support intervention options for autistic population

Area of Science:

• Neuroscience
• Neuropsychiatry
• Developmental Neuroscience

Background:

• Autism Spectrum Disorder (ASD) affects ~1% of the global population, characterized by atypical neuroplasticity.
• Repetitive transcranial magnetic stimulation (rTMS) shows therapeutic potential for neuropsychiatric conditions, including autism.
• Recent studies suggest autistic adults exhibit hyper-plasticity, specifically excessive long-term potentiation (LTP) in the motor cortex.

Purpose of the Study:

• To investigate neuroplasticity differences in autistic adults compared to neurotypical controls.
• To propose novel rTMS protocols targeting motor, sensory, and executive functions in autism.
• To evaluate the efficacy of bilateral rTMS in reducing hyper-plasticity and improving functional outcomes.

Main Methods:

• Utilizing transcranial magnetic stimulation (TMS) paradigms, including theta-burst stimulation (TBS).
• Developing a framework to assess neuroplasticity in motor, sensory, and dorsolateral prefrontal cortices.
• Proposing intervention protocols using bilateral rTMS.

Main Results:

• Hypothesized hyper-plasticity in motor, sensory, and prefrontal cortices of autistic adults.
• Anticipated link between hyper-plasticity and difficulties in motor, sensory, and executive functions.
• Proposed investigation into the therapeutic effects of bilateral rTMS on these functions.

Conclusions:

• Hyper-plasticity may underlie functional challenges in autistic adults.
• Neuroplasticity-based rTMS interventions offer a potential therapeutic avenue for autism.
• This research aims to enhance autism treatments and provide biological insights into brain mechanisms.
