Autistic spectrum disorders as functional disconnection syndrome

Area of Science:

• Neuroscience
• Developmental Neuroscience
• Autism Research

Background:

• Autistic spectrum disorder (ASD) is characterized by functional disconnection and reduced activity in the right hemisphere.
• This hemispheric imbalance is linked to observed increases in sympathetic activation and various ASD symptoms.
• Ineffective interhemispheric communication and desynchronization are proposed as primary issues in ASD.

Purpose of the Study:

• To explain ASD symptoms through functional disconnection and reduced right hemisphere coherence.
• To propose multimodal therapeutic strategies for improving interhemispheric communication in ASD.
• To investigate the potential of unilateral hemispheric stimulation to enhance brain synchrony.

Main Methods:

• Theoretical framework outlining the role of right hemisphere dysfunction in ASD.
• Proposal of multimodal therapeusis including somatosensory, cognitive, behavioral, and biochemical interventions.
• Hypothesized mechanism of unilateral hemispheric stimulation to increase thalamocortical pathway oscillations.

Main Results:

• Functional disconnection and reduced right hemisphere coherence are hypothesized to underpin ASD symptoms and sympathetic activation.
• Multimodal interventions are proposed to enhance overall health, reduce inflammation, and increase right hemisphere activity.
• Unilateral stimulation is hypothesized to increase temporal oscillations, improving interhemispheric coherence.

Conclusions:

• Improving coordination and coherence between brain hemispheres is key to addressing ASD symptoms.
• Multimodal therapies targeting inflammation and enhancing right hemisphere activity offer a promising approach.
• Increased hemispheric oscillation speed may enhance motor and cognitive binding in individuals with ASD.
