ObjectiveTo investigate if people with subjective memory complaints (SMC) but no objective deficits are at increased risk of developing mild cognitive impairment (MCI) and dementia.
MethodsMajor electronic databases were searched till 03/2014 and a meta-analysis was conducted using inception cohort studies.
ResultsAcross 28 studies there were 29,723 unique individuals (14,714 with SMC and 15,009 without SMC) (mean 71.6 years) followed on average for 4.8 years through to dementia. The annual conversion rate (ACR) of SMC to dementia was 2.33% (95% CI = 1.93% -2.78%) a relative risk (RR) of 2.07 (95% CI = 1.76 to 2.44) compared to those without SMC (n=15,009). From 11 studies the ACR of developing MCI was 6.67% (95% CI = 4.70 -8.95%).In long-term studies over 5 years, 14.5% (9.67 -19.1%) of people with SMC developed dementia and 26.6% (95% CI =15.3-39.7) went on to develop MCI. The ACR from SMC to dementia and MCI were comparable in community and non-community settings.
ConclusionOlder people with SMC but no objective complaints are twice as likely to develop dementia as individuals without SMC. Approximately 2.3% and 6.6% of older people with SMC will progress to dementia and MCI per year.
Summations
•Among people with SMC but without objective complaints, the annual conversion rate (ACR) to MCI is 6.6%, whilst it is 2.3% to dementia, compared to 1% in those without SMC• Over about 5 years, 24.4% of those with SMC will develop MCI, whilst 10.9% will convert to dementia, compared to 4.6% in those without SMC.
4• Overall, the risk of developing dementia is double in those with SMC compared to those without SMC.• Considerations• It was not possible to stratify the results according to type of dementia or the diagnosis method.• A wide range of definitions were used to capture SMC and it was not possible to conduct subgroup analysis to determine if this influenced the results.• Most of the analysis had high heterogeneity and there was evidence of publication bias in some of the analyses.
Depression, adjustment disorder and anxiety are common after stroke. Risk factors are aphasia, dominant hemispheric lesions and past personal/family history of depression but not time since stroke.
Rates of mammography screening are lower in women with mental illness, particularly women with SMI, and this is not explained by the presence of emotional distress. Disparities in medical care due to mental illness clearly extend into preventive population screening.
The pericardium is an uncommon site for manifestation of pheochromocytoma. Herein, the case of a 57-year-old man with cardiac tamponade is presented. Pericardiocentesis was performed, and the vital signs were stabilized afterwards. An abdominal computed tomography (CT) scan illustrated a nonhomogeneous right adrenal mass suspicious of pheochromocytoma, planned for right adrenalectomy. He recovered well after surgery, and his subsequent follow-ups did not reveal any complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
