: Estradiol promotes neuronal growth, transmission, survival, myelinization, plasticity, synaptogenesis, and dendritic branching and it improves cognitive function. Alzheimer’s disease (AD) is characterized by amyloid plaques, neurofibrillary tangles, and the loss of neuronal connection in the brain. Genomic analysis has concluded that hypoestrogenism influences the APOE gene and increases the risk of AD. Premature ovarian insufficiency (POI) is defined as oligo/amenorrhea in women below 40 years of age, low estradiol, and high-gonadotropin levels. Early symptoms and signs of POI must be detected in time in order to prevent subsequent complications, such as Alzheimer’s disease. Meta-analysis has shown favorable effects of estrogen in preventing Alzheimer’s. We measured some of the typical markers of AD in women with POI such as interleukin 6 (IL-6), interleukin 8 (IL-8), tissue necrosis factor α (TNFα), TAU1, TREM2, and amyloid precursor proteins (APP). While FSH, LH, and IL-8 were significantly higher in POI group, compared to controls, testosterone and DHEAS were lower. A significant decrease in IL-6 was found in the POI group during a 6-month therapy, as well as an increase in amyloid precursor proteins. CONCLUSION: Neurological complications of POI, such as declining short-term memory, cognitive function, and dementia, have to be promptly stopped by initiating estro-progestogen therapy in POI. A long-term continuation of the therapy would be strongly advised.
