Resumo em Inglês:

A review/analysis of current literature on exemplary multicenter registries of clinical dementias was conducted as a comparative basis for a proposed Cuban registry on cognitive impairment and dementia. The study of mental health disorders has been predominantly based on clinical concepts and criteria, and only in recent years a public health approach has been applied. Traditional epidemiological studies do not reveal patterns of cognitive impairment and behavioral disorders (particularly dementias) in routine clinical practice in a defined geographic area, which would provide essential information for longterm planning and allocation of health and social resources. Thus, multicenter clinical registries have become an important source of clinical and epidemiological data on dementias in recent decades. This article addresses the Cuban proposal for an automated national dementia registry, comparing it to others internationally. The registry would be housed in the Neurology and Neurosurgery Institute, and would include a duly protected surveillance network hosted on the Institute's website. Such a multicenter dementia registry based on epidemiological surveillance methods and limited to a defined area would provide new, valid, representative and current data on dementia occurrence patterns by subtype, flow of case identification and referral from primary care, as well as the main clinical features of patients at the time of their first contact with health services. This information would support development of health planning policies for implementation of programs aimed at improved distribution of social and health resources in the affected population, monitoring of the disorder's natural evolution and identification of preventive measures. The scientific benefits would be equally important: production of new knowledge, generation of hypotheses for clinical research projects, standardization of diagnostic criteria, and promotion of multicenter research in both national and multinational centers.
