A postal questionnaire was sent to 1000 subjects aged over 65 years randomly selected from the age/sex register of five group practices, 90% of subjects returning adequate information. Thirty per cent of responders reported dizziness; 27% of these had symptoms more than once per month and 37% had symptoms which lasted longer than 1 minute. Dizziness was most commonly provoked by postural change and head and neck movement. The prevalence of dizziness increased with age and was higher in women but these differences were not statistically significant. The prevalence of symptoms occurring more than once per month was significantly greater with increasing age (p = 0.0003). Dizziness was significantly associated with angina and previous myocardial infarction (p < 0.001) and antihypertensive therapy (p < 0.05) but not with current smoking, diabetes mellitus or previous stroke.

BackgroundThere are no previous whole-country studies on mental health and relationships with general health in intellectual disability populations; study results vary.AimsTo determine the prevalence of mental health conditions and relationships with general health in a total population with and without intellectual disabilities.MethodNinety-four per cent completed Scotland’s Census 2011. Data on intellectual disabilities, mental health and general health were extracted, and the association between them was investigated.ResultsA total of 26 349/5 295 403 (0.5%) had intellectual disabilities. In total, 12.8% children, 23.4% adults and 27.2% older adults had mental health conditions compared with 0.3, 5.3 and 4.5% of the general population. Intellectual disabilities predicted mental health conditions; odds ratio (OR)=7.1 (95% CI 6.8–7.3). General health was substantially poorer and associated with mental health conditions; fair health OR=1.8 (95% CI 1.7–1.9), bad/very bad health OR=4.2 (95% CI 3.9–4.6).ConclusionsThese large-scale, whole-country study findings are important, given the previously stated lack of confidence in comparative prevalence results, and the need to plan services accordingly.Declaration of interestNone.Copyright and usage© The Royal College of Psychiatrists 2017.

ObjectivesTo investigate the prevalence of comorbid mental health conditions and physical disabilities in a whole country population of adults aged 25+ with and without reported autism.DesignSecondary analysis of Scotland’s Census, 2011 data. Cross-sectional study.SettingGeneral population.Participants94% of Scotland’s population, including 6649/3 746 584 adults aged 25+ reported to have autism.Main outcome measuresPrevalence of six comorbidities: deafness or partial hearing loss, blindness or partial sight loss, intellectual disabilities, mental health conditions, physical disability and other condition; ORs (95% CI) of autism predicting these comorbidities, adjusted for age and gender; and OR for age and gender in predicting comorbidities within the population with reported autism.ResultsComorbidities were common: deafness/hearing loss—17.5%; blindness/sight loss—12.1%; intellectual disabilities—29.4%; mental health conditions—33.0%; physical disability—30.7%; other condition—34.1%. Autism statistically predicted all of the conditions: OR 3.3 (95% CI 3.1 to 3.6) for deafness or partial hearing loss, OR 8.5 (95% CI 7.9 to 9.2) for blindness or partial sight loss, OR 94.6 (95% CI 89.4 to 100.0) for intellectual disabilities, OR 8.6 (95% CI 8.2 to 9.0) for mental health conditions, OR 6.2 (95% CI 5.8 to 6.6) for physical disability and OR 2.6 (95% CI 2.5 to 2.8) for other condition. Contrary to findings within the general population, female gender predicted all conditions within the population with reported autism, including intellectual disabilities (OR=1.4).ConclusionsClinicians need heightened awareness of comorbidities in adults with autism to improve detection and suitable care, especially given the added complexity of assessment in this population and the fact that hearing and visual impairments may cause additional difficulties with reciprocal communication which are also a feature of autism; hence posing further challenges in assessment.
