Validation of MoCA-B and MoCA-Blind for Screening Cognitive Decline

The objective of this observational study is to assess the efficacy of two neuropsychological tests (MoCA-B and MoCA-Blind) in detecting cognitive decline in older adults. The main questions it aims to answer are: Can the results obtained by older adults on the MoCA-B distinguish between those with and without cognitive decline? Can the results obtained by older adults on the MoCA-Blind distinguish between those with and without cognitive decline? Participants will be required to: 1. Complete a sociodemographic questionnaire; 2. Undergo a visual acuity test; 3. Complete the Pfeffer and IQCODE scales; and 4. Complete the MMSE, MoCA-B, and MoCA-Blind.
