Answer

Answer

Various neuropsychiatric disorders (eg depression, [22] seasonal affective disorder, bipolar disorder [23] ) have been linked to hyposmia. It has also been shown that patients with schizophrenia or acute major depressive disorder have not only decreased olfactory sensitivity but also reduced olfactory bulb volumes. [24, 25] The neurologic explanation for these findings is under active investigation and may lead to new therapies or early detection screening tools.
