ABSTRACT

INTRODUCTION The Girona Dementia Registry (ReDeGi, from Spanish: Registro de Demencias de Girona) is a population-based epidemiological surveillance mechanism that registers the cases of dementia diagnosed by the reference centres in the Girona Health District.

AIM To report on the frequency of the diagnoses and their clinical and sociodemographic characteristics, as well as to compare differences depending on the different subtypes of dementia.

PATIENTS AND METHODS The method used consisted in a consecutive standardised register of the diagnoses involving dementia in specialised procedures in the Girona Health District between 2007 and 2010.

RESULTS A total of 2814 cases were registered, which represents a clinical incidence of 6.6 cases per 1000 persons/year. Of this total number, 69.2% were primary degenerative dementias, 18.9% were dementias secondary to a vascular pathology, 5.4% were other secondary dementias and 6.5% were non-specific dementias. The mean age was 79.2 ± 7.6 years (range: 33-99 years) and 59.3% were females. The mean time elapsed since the onset of symptoms and clinical diagnosis was 2.5 ± 1.7 years. The mean score on the Blessed dementia scale was 7.7 ± 4.5 points and in the minimental test it was 17.6 ± 5.4 points. A family history of dementia was present in 26.6% of cases and 69.6% presented one or more cardiovascular risk factors. In 60.6% of cases they were cases of mild dementia, 28.5% were moderate and 10.9% were severe cases.

CONCLUSIONS The epidemiological surveillance activity carried out by the ReDeGi throughout the period 2007-2010 has made it possible to record information that is extremely valuable for the planning and management of health care resources.
