title: [The feasibility of a registry of dementias: clinical features and diagnostic coverage].
abstract: OBJECTIVE
  Classic epidemiological studies do not allow to know the dementia patterns of derivation and diagnosis in a defined territory. This information is fundamental for the planning and distribution of the sanitary and social resources to a medium-to-long term. The results of a pilot-registry program for dementia cases based on the population surveillance principles is presented.
  
  
  METHODS
  Consecutive and standardized registry of the incident dementia diagnoses of a memory unit during biennium 2004-2005.
  
  
  RESULTS
  670 new cases of dementia, of which 74% corresponded to Alzheimer's disease, were registered. The presenile dementias were 10.3% of the cases. The mean time between the beginning of the symptoms and the clinical diagnosis was of 2.4 years and the severity of the dementia was mild in 60.0%. 90.1% of the cases lived in their homes or in a relative's home. The hypertension, the diabetes mellitus and the antecedents of depressive disease were the more frequent pathological antecedents (> 20%). The diagnostic coverage based on the estimated dementia cases was 75% for the memory unit's reference territorial area. The diagnostic coverage for the health region of Girona was 38%.
  
  
  CONCLUSIONS
  The registered data show the viability and validity of the proposed registry program for dementia cases. Nowadays the registry program is able to extend the diagnostic coverage all over the health region of Girona.
