Polycystic Ovary Syndrome (PCOS), recently renamed polyendocrine metabolic ovarian syndrome (PMOS) to better reflect its diverse endocrine and metabolic features, is a complex disorder affecting approximately 1 in 8 women of reproductive age. While symptoms often include menstrual irregularities, elevated androgen levels, acne, and hirsutism, medical experts note that regular menstrual cycles do not necessarily guarantee regular ovulation or the absence of the syndrome. Professional evaluation is required to differentiate symptoms like hair loss from thyroid issues or nutritional deficiencies.

Recent scientific reviews published in the Journal of the Endocrine Society have identified a potential link between PMOS and cognitive changes. Research suggests women with the condition may experience weaker memory, attention issues, and changes in brain structure and connectivity. Dr. Ricardo Aziz of the University of Alabama at Birmingham noted that these findings could indicate an increased risk for Alzheimer’s and dementia, although direct evidence remains inconsistent across studies.

Researchers hypothesize that these cognitive issues may stem from associated conditions such as insulin resistance, obesity, and chronic inflammation rather than the syndrome itself. Further long-term research is needed to determine if hormonal and metabolic changes directly impact brain function. As a lifelong condition, PMOS necessitates ongoing monitoring of metabolic, cardiovascular, and endometrial health risks through menopause.
