Autism Spectrum Disorders (ASD).

QEEG-guided neurofeedback for Autism Spectrum Disorders (ASD) works by identifying and modifying specific brainwave patterns that are commonly associated with ASD symptoms. The QEEG helps to map out areas of dysregulation in the brain, offering a clearer understanding of how the brain functions and where improvements can be targeted.

​

Common Brain Patterns Associated with ASD:

1. Increased Delta and Theta Activity (Slow Wave Activity): Individuals with ASD often shown elevated slow-wave activity, particularly in the frontal and central regions. Increased Delta and Theta may contribute to difficulties with attention, processing speed, and executive function.

​

2. Decreased Alpha Activity: Alpha waves, typically associated with relaxed states and cognitive readiness, are often reduced in individuals with ASD, particularly in posterior regions. This reduction may contribute to issues with social engagement, sensory processing, and cognitive regulation.

​

2. Excess Beta Activity: Some studies have observed elevated Beta activity, especially in the frontal lobes, which may be linked to hyperarousal, repetitive behaviours, and anxiety commonly seen with ASD.

What Does the Research Say?:

 

A 2021 randomized controlled trial found that neurofeedback succeeded to decrease children's theta/beta ratio, resulting in improvements in cognitive and social functions. Similarly, a 2021 systematic review found that 94% of nonrandomized controlled and experimental trials concerning neurofeedback for autism spectrum disorders found positive results, including long-term effects.
