Perimenopausal hormone shifts alter central nervous system signaling, sleep architecture, and metabolic regulation. Vitalis Her combines validated medical screening (MRS, PHQ-9, GAD-7) with birth control interaction logic and transdermal safety data.

Validated Medical Assessment

Menopause Rating Scale (MRS) Assessment

0% Complete

Clinical Scale Overview: The Menopause Rating Scale (MRS) is an internationally validated 11-item diagnostic tool covering Somato-Vegetative, Psychological, and Urogenital domains. Rate severity over the past 30 days (0 = None to 4 = Very Severe).

Neuroendocrine Mechanisms of Perimenopausal Symptoms

During perimenopause, ovarian follicle depletion leads to erratic 17β-estradiol and progesterone fluctuations. These biochemical swings alter central neuroreceptor networks and biological systems:

Hypothalamic Thermoregulation

Estrogen drop destabilizes KNDy neurons in the infundibular nucleus, narrowing the brain's neutral thermal zone and triggering flushing and night sweats.

GABA-A Neurosteroid Withdrawal

Progesterone drops eliminate allopregnanolone modulation of GABA-A receptors, triggering unprovoked panic and abrupt 3 AM awakenings.

Serotonin & Dopamine Signaling

Lower estradiol reduces tryptophan hydroxylase activity, decreasing synaptic serotonin density and precipitating mood lability and fatigue.

Cerebral Bioenergetics & Brain Fog

Estradiol regulates glucose transport (GLUT1/3) in cerebral mitochondria. Falling levels drop brain ATP production by 20–25%, causing cognitive lags.
