Neurofeedback training for eating disorders:
21 anorexic and 54 bulimic at Mirasol RTC for Eating Disorders in Tucson, AZ.
All women were independently diagnosed with an eating disorder prior to admission.
Intake assessments: TOVA, MMPI-2, BDI-2, Eating Disorders Inventory-2, Eysenck Personality Inventory, Tellegen Absorption Scale, and the Marlowe Crown Test.
Right brain dysfunction with significantly increased Delta activity under cognitive challenge.
Research-designed training protocols were statistically more likely to reduce or eliminate the need for medication.
Significant decrease in Beck Depression Inv-2 scores, neuroticism scores, and all EDI-2 scores. A significant increase in extroversion scores. MMPI-2 changes reveal a reduction in symptoms associated with distress.
Anorexics gained weight significantly. Bulimics lost 3lb/mo during treatment.
All tests significant at the p>.03 level.
63 subjects responded to 6-month follow-up.
Weight changes continued in the proper direction. Anorexics gained about 1 lb per week. Overweight bulimics lost about 3 lbs per month.
80-100% reduction in depression on BDI (clinical vs. QEEG driven protocol)
Depression reduction the key factor in sustained success (Melanie Klein’s ‘depressive position’)
65% are doing well in recovery. 80% have had some resurgence of symptoms.
Maintenance of preferred weight direction was better for anorexics (p>.05) than for bulimics (p>.08), and third for overweight (N=63) at 6-months.
