Abstract

Introduction: Dementia has been a public health concern for several years. As the population continuously ages, the prevalence of dementia is projected to significantly rise, thus governments will face an increasing demand for support services. Unfortunately, dementia is not recognized as a major public health concern in the Philippines. As the extent of the dementia epidemic needs to be further delineated in the Philippines, and research on dementia is still limited, a larger study is needed to provide more information about the disease burden. This will raise awareness and inform policy makers about the necessity of social and health care reform in dementia care.

We aimed to collect uniform data from patients with cognitive impairment and determine the frequency of dementia and mild cognitive impairment in the study population. These data are crucial for providing information to policy makers in the country.

Methods and Analysis: This is a multi-center, prospective, observational, non-interventional study and standing database of patients clinically diagnosed with Mild Cognitive Impairment (MCI) or dementia seen at the participating training institutions. Corresponding anonymized data on demographics, medical history, risk factors, level of functional impairment, diagnosis, baseline cognitive scores and management will be collected from each patient and entered into the database using a secure online data collection tool. Collective data will be extracted, summarized and analyzed every year with oversight provided by the Philippine Neurological Association (PNA).

Ethics and Dissemination: Approval from the ethics committees or institutional review boards (EC/IRB) was obtained from the Single Joint Research Ethics Board and all participating institutions.

The PNA1DB-Dementia initiative will be crucial in providing information to policy makers, to further enhance the implementation of the Mental Health Act. The dissemination of results will be conducted through scientific or public conferences and scientific journal publication.
