HealthDay News — Noninvasive neurotechnology for autocalibration of neural oscillations may reduce symptoms associated with menopause, according to a study published in Menopause.
Charles H. Tegeler, MD, from the Wake Forest School of Medicine in Winston-Salem, North Carolina, and colleagues examined outcomes associated with use of HIgh-resolution, Relational, Resonance-based Electroencephalic Mirroring (HIRREM) by women with perimenopausal and postmenopausal hot flashes (median age, 56 years). Data were collected for 12 women with hot flashes who underwent a median of 13 intervention sessions for a median of 9.5 days. Daily diaries were used to record hot flash frequency and severity.
The researchers observed a −0.97 median change in hot flash severity score (P = 0.015). Changes of −8.5 and −5.5 points were noted in sleep and depression scores, respectively. For right and left temporal high-frequency brain electrical activity, the median sum of amplitudes was 8.44 µV at baseline, with a median change of −2.96 µV by the final session (P = 0.0005).
“Hot flash frequency and severity, symptoms of insomnia and depression, and temporal high-frequency brain electrical activity decrease after HIRREM,” the authors write. “Larger controlled trials with longer follow-up are warranted.”
