The general prevalence out of dementia is nine.23 (95% CI: 7.80–) according to DRG criteria and you may step three.65 (95% CI: 2.79–cuatro.97) predicated on DSM-IV standards (Desk step 3). The brand new prevalence of alzhiemer’s disease try comparable between the two websites, but in the latest urban website incidence of DSM-IV dementia are nearly twice one to throughout the outlying webpages. Sheer Advertisement seemed to be the most frequent subtype both in elements, particularly in the brand new urban area, even in the event as much as 1/3rd of one’s circumstances cannot getting assigned to almost any type of subtype (Dining table 4).

CDR clinical seriousness are fundamentally higher when you look at the persons which have DSM-IV alzhiemer’s disease than the people with dementia. Suspicious diagnoses from DSM-IV dementia have been nearly inexistent (we.e. one in 51), while dubious alzhiemer’s disease diagnoses portrayed around you to fifth (21.7%) of your own overall. Although not, despite leaving out all the questionable diagnoses, the fresh new dementia frequency rate surpassed regarding DSM-IV alzhiemer’s disease in section (Desk 5).

Correlates of alzhiemer’s disease

Table six merchandise investigation out-of a few of the sociodemographic correlates regarding alzhiemer’s disease. The new incidence out of dementia was strongly many years-centered for both requirements, along with both websites (Desk 3). There was a regular trend to possess a keen inverse organization anywhere between household property additionally the frequency out-of dementia. There were and possibly significant inverse relationships anywhere between studies top and you can alzhiemer’s disease prevalence (metropolitan alzhiemer’s disease) otherwise styles in that guidelines (outlying alzhiemer’s disease and metropolitan DSM-IV). not, on the outlying urban area advanced schooling accounts was indeed from the good large prevalence away from dementia.


We conducted a comprehensive that-stage survey from one or two catchment parts, that urban additionally the almost every other rural, about southern out of Portugal, on the main purpose away from quoting the fresh frequency away from alzhiemer’s disease. Of the adopting the DRG protocols, i likewise recognized depression or any other psychological disorders, and that’s advertised after that. We were seeking the brand new congested urban/suburban elements near Lisbon (the administrative centre), and also in the lower populace-thickness rural internal nation, in which chance activities to own dementia may differ. One of these latter regions was Alentejo, with a high proportion away from the elderly (twenty-four.2%) and informative account within reduced within the Europe (9.6% illiterate) . The option of all of our urban and you will rural catchment portion mirrored these welfare. In the full society shot, this new prevalence off alzhiemer’s disease is actually nine.23% (95% CI: seven.80–) with the DRG formula and you can step three.65% (95% CI: 2.79–cuatro.97) playing with DSM-IV criteria.


The past try size (letter = 1405) was acceptable, once the almost a 3rd from Western european studies report sample brands under five-hundred inside type of training . In the area epidemiological training, response costs usually are a bit high during the less set-up settings, and those hit in our study was in keeping with, or slightly a lot better than other present knowledge inside the highest income places . Of contrasting involving the urban together with rural city, a comparable research method is actually then followed in both by same browse classification, which ought to guarantee an area assessment into good factor. Yet not, possible bias cannot be omitted considering high involvement rates regarding the outlying area. Inside urban Fernao Ferro, a proportion out of households turned into sunday property, and you may weaker internet sites perhaps compromised the new depend on away from potential members inside the making it possible for interviewers on their homes.

We discover a top frequency from alzhiemer’s disease utilizing the DRG diagnostic algorithm, versus prevalence out-of DSM-IV dementia, because seen in earlier times along side other sites . As the frequency away from dementia (9.2%) try lined up for the diversity reported in other DRG studies , the newest incidence from DSM-IV alzhiemer’s disease (step three.7%) might be named low in the brand new light of recent critiques of your frequency regarding dementia from the globe area . The newest incidence from DSM-IV alzhiemer’s disease was lower, as well as the discrepancy ranging from DSM-IV alzhiemer’s disease and you may alzhiemer’s disease incidence highest from the outlying in contrast to the latest metropolitan webpages. Just as in lower and middle-income group nations, lightweight alzhiemer’s disease might have been around-seen by DSM-IV conditions because of problems when you look at the setting up brand new expectations of societal impairment, particularly in outlying options characterised from the low degree and you may minimal sense of dementia as an ailment different from typical ageing .
