This is a pragmatic, multi-center, prospective, observational, non-interventional study and standing database of patients seen at the training institution for cognitive impairment diagnosed with Mild Cognitive Impairment (MCI) or Dementia.

All patients seen at the training institution clinically diagnosed with MCI or dementia by their neurologists will be invited to participate in the study. The investigators will confirm the diagnosis and will explain the study as well as the patient information sheet to the patient and/or legal representative. All eligible patients seen will be assigned a study identification number. Data will be collected by the investigators as the patient undergoes routine clinical evaluation. Corresponding anonymized data on demographics, medical history and risk factors, level of functional impairment, diagnosis, baseline cognitive scores and management will be collected from each patient and entered in the database using a secure online data collection tool.

Corresponding anonymized data on demographics, medical history and risk factors, level of functional impairment, diagnosis, baseline cognitive scores and management will be collected from each patient and entered in the database using a secure online data collection tool. Patients who withdraw participation verbally or in writing are excluded by the investigator from further participation. Withdrawal from the study will be properly documented, including date, time, and reason for withdrawal. Withdrawn subjects will not have their clinical data included in the database.

Collective data will be extracted, summarized, and analyzed every year with oversight provided by the Philippine Neurological Association (PNA). To be able to assess trends and changes over time, data collection for this study will span 3 years from study initiation, after which the utility of an extension or a re-implementation of the study will be assessed by the PNA.
