2. Global Cognitive Function and Depression: Global cognitive function will be assessed using the MMSE. The Beck's Depression Inventory (BDI) will be administered. MCI Screen: There are no consensus criteria for the clinical classification of MCI. The MoCA will be used to screen participants for MCI. The MoCA is a brief screening tool for MCI with high sensitivity and specificity. It is a 30-point test covering eight cognitive domains and scores below 26 are considered to be abnormal. A bonus point is given to those with less than 12 years of education.
