    This study involving 120 patients with androgenetic alopecia (AGA) found that psychological stress significantly impacts neurotrophic factor levels and correlates with disease progression. Patients were divided into stress (n=90) and non-stress (n=30) groups. The stress group exhibited higher cortisol levels and altered neurotrophic factor profiles, including reduced levels of nerve growth factor, brain-derived neurotrophic factor, and glial cell line-derived neurotrophic factor, but increased levels of neurotrophin-3 and neurotrophin-4. These changes were associated with more severe AGA progression, even after 1 year of treatment with 5% minoxidil. The study suggests that managing both physiological and psychological aspects of AGA is crucial, although its retrospective design and small sample size limit the generalizability of the findings.
