5. Conclusion
MinD is the most prevalent mental disorder in old age (Preville et al., 2008). It is found to be a risk factor for MDD and MCI in late life. A number of factors are associated with MinD such as female gender, presence of somatic (stroke, myocardial infarction) and mental health disturbances (generalized anxiety disorder, history of MDD), and psychological problems. Our review, aiming to elucidate MinD, may enable easier recognition, treatment, and prevention of possible complications of this disorder in the future.
