EEG Neurofeedback study (Jerusiewicz, 2002)

  • 20 children with ASD in experimental group.
  • 20 children with ASD in control group
  • Experimental group completed an average of 36 neurofeedback sessions
  • Pre- and post-treatment scores on the Autism Treatment Evaluation Checklist (ATEC) were collected.

Pilot study results: percentage of improvement on ATEC

Neurofeedback group        Control group

Speech/Language            29%                       0%

Sociability                         33%                       7%

Sensory/Cognitive            17%                       0%

Health/Physical/Behavior  26%                       5%

Total                                 26%                       3%

 

HEG Neurofeedback research (Limsila & Toomim, 2003)

  • Largest HEG study to date.
  • 180 autistic children in Thailand
  • After 40 sessions, the cohort’s mean HEG readings (prefrontal activation) increased 53%
  • Of the 81 subjects who were studying in public school, 86% increased their GPA by more than 0.5 (mean = 0.94) points on a 4-point scale
  • Only 4% decreased their GPA by more than 0.5 points (mean = 0.57)

 

EEG Neurofeedback research (Coben & Padolsky, 2006)

  • 37 subjects with autism
  • 20 EEG neurofeedback sessions
  • Wait list control group (n=12) matched for gender, age, race, handedness, IQ & treatment
  • 89% success rate
  • 40% reduction of autistic symptoms on ATEC
  • Significant improvements on neuropsychological tests of Attention, Language, Visual-Perception & Executive Functioning
  • QEEG & infrared imaging demonstrated gains

 

HEG Neurofeedback Research (Coben 2006)

  • 28 subjects with autism
  • 20 nir or pir HEG sessions
  • Wait list control group (n=12) matched for gender, age, race, handedness, IQ & treatment
  • All subjects had previously completed 20 sessions of EEG neurofeedback
  • All subjects had identified frontal system dysfunction based on neurobehavioral testing, neuropsychological testing, infrared imaging, and QEEG data
  • 90% success rate
  • 42% reduction in autistic symptoms on ATEC
  • 43% reduction in social interaction deficits
  • 47% reduction in communication deficits
  • 44% reduction in sensory/cognitive deficits
  • 39% reduction in behavior deficits
  • Statistically significant (p < .05) improvements in neurobehavioral and neuropsychological functioning
