Fast and Noninvasive Hair Test for Preliminary Diagnosis of Mood Disorders

This study aimed to develop a fast and noninvasive test for the preliminary diagnosis of mood disorders using hair samples. It involved 75 control subjects and 40 patients with mood disorders, aged 18-65 years. Hair samples were analyzed using ATR-FTIR spectroscopy, and the results were examined with chemometric methods. The study found potential differences in spectra intensity, particularly around 2800-3100 cm^-1 and 1460 cm^-1, which are related to protein vibrations. These findings provided a promising foundation for developing a test for the initial diagnosis of mood disorders.
