Pilot study of the incidence and prognosis of XXXX in Aberdeen, United Kingdom: methods and preliminary results.

@entity1 @entity2003 @entity304 @entity4652 @entity191 @entity2845 @entity400
The objective of this study was to test the methods for a large study of the incidence and prognosis of @entity191 and other @entity4652 and provide provisional incidence figures. This was a community-based prospective study to identify @entity1 with newly diagnosed non-drug-induced @entity304 (>or=2 of @entity400 , @entity2003 , @entity2845 , postural instability) from a population of 148,600 @entity1 in Aberdeen, Scotland, over 18 months. Multiple search strategies were used to identify @entity1 , including some population screening. Incident @entity1 and age/sex-matched controls had assessments of impairment, disability, quality of life, mood, and cognition and are being followed up yearly. Two hundred and two @entity1 with possible @entity191 symptoms were assessed, and 82 incident @entity1 were identified, 50 with probable @entity191 . The crude incidences of probable @entity304 and probable @entity191 were 31.4/100,000/year (95% CI: 24.5-39.7) and 22.4/100,000/year (95% CI: 16.6-29.6), respectively. The mean age of diagnosis of @entity191 was 76.1 +/- 10.0 years and the incidence was greater in @entity1 . The methods were generally successful. Provisionally, we found a higher incidence of @entity191 than other comparable studies, and our @entity1 were considerably older. This may reflect better case ascertainment in the elderly. A larger study is planned.
