Dementia with cortical Lewy bodies (LBD) was first described by Okazakiet alin 1961 and is now recognised as a relatively common cause of the dementia syndrome. The true prevalence of LBD is unknown. In post-mortem studies of patients diagnosed as having dementia in life, the mean frequency of Lewy body dementia is 12.5% (Byrne, 1997). Clinically diagnosed LBD (using operational clinical criteria) is found in 10–23% of patients presenting to, or in the care of, psychogeriatric services (Collertonet al, 1996). What is not yet certain is its nosological status; opinion is divided between regarding it as a variety of Alzheimer's disease (the Lewy body variant), a distinct disease (senile dementia of the Lewy body type) or a spectrum disorder related to both Parkinson's disease and to Alzheimer's disease (Byrne, 1992).

Objectives: To quantify the rate of cognitive decline on the Mini-Mental State Examination (MMSE) in autopsy-diagnosed Lewy body variant (LBV) of Alzheimer's disease (AD) cases. We hypothesized that LBV patients would have a faster cognitive decline and shorter survival compared with patients with pure AD.Background: Prior reports have shown extrapyramidal signs to be associated with a poorer prognosis in AD. It has been suggested that LBV is often characterized by a rapidly progressive course. Few data are available regarding the rate of cognitive decline in autopsy-confirmed LBV dementia cases.Methods: We searched the databases of the University of California-San Diego Alzheimer's Disease Research Center and the Consortium to Establish a Registry in Alzheimer's Disease (CERAD) for dementia cases with 1) an autopsy diagnosis of definite or probable AD (CERAD criteria) with concomitant Lewy bodies and 2) longitudinal MMSE assessments. This resulted in a series of 40 LBV cases and 148 AD cases without Lewy bodies, with comparable baseline MMSE scores, age, and education. The rate of cognitive decline was calculated as the baseline MMSE - final MMSE. Methods were devised to reduce floor effects on the MMSE.Results: The average rate of cognitive decline was -5.8 ± 4.5 points/y in LBV and -4.1 ± 3.0 points/y in AD (t-test, p< 0.01). The LBV group declined a similar amount on the MMSE (means, -10.0 versus -9.6 points) over a significantly shorter time interval (1.9 versus 2.7 years; p = 0.005) than did AD patients. At baseline, the mean MMSE scores were nearly identical (18.2 in LBV; 17.8 in AD), but on follow-up examinations approximately 1, 2, and 3 years later, there were intergroup mean differences of 1.8 points (two-tailed p = 0.19), 4.2 points (p = 0.04), and 5.6 points (p = 0.03), respectively. The LBV cases had shorter survival time from the onset of cognitive symptoms (7.7 ± 3.0 years versus 9.3 ± 3.5 years; p = 0.007) and a shorter mean survival after entry/baseline, which was of marginal significance (3.6 versus 4.1 years; p = 0.11).Conclusions: This study demonstrates that LBV is characterized by a faster cognitive decline and accelerated mortality compared with AD.

The association of physical activity with dementia and its subtypes has remained controversial in the literature and has continued to be a subject of debate among researchers. A systematic review and meta-analysis of longitudinal studies on the relationship between physical activity and the risk of cognitive decline, all-cause dementia, Alzheimer’s disease, and vascular dementia among nondemented subjects are considered. A comprehensive literature search in all available databases was conducted up until April 2016. Well-defined inclusion and exclusion criteria were developed with focus on prospective studies ≥ 12 months. The overall sample from all studies is 117410 with the highest follow-up of 28 years. The analyses are performed with both Bayesian parametric and nonparametric models. Our analysis reveals a protective effect for high physical activity on all-cause dementia, odds ratio of 0.79, 95% CI (0.69, 0.88), a higher and better protective effect for Alzheimer’s disease, odds ratio of 0.62, 95% CI (0.49, 0.75), cognitive decline odds ratio of 0.67, 95% CI (0.55, 0.78), and a nonprotective effect for vascular dementia of 0.92, 95% CI (0.62, 1.30). Our findings suggest that physical activity is more protective against Alzheimer’s disease than it is for all-cause dementia, vascular dementia, and cognitive decline.

Prevalence Of Dementia

There is little doubt that dementia is a very common cause of disability and dependency in our society. Since dementia of whatever type is usually more common with increasing age, then as population demographics change, so will the prevalence of dementia. Dementia is a generic term and the objective for clinicians, once dementia is suspected, is to attempt to define the cause. Alzheimer's disease is the most common cause of dementia, and in most centres vascular dementia would feature as the next most common aetiology. In some centres, Lewy body dementia is the second most common cause. Mixed Alzheimer's disease and vascular dementia would also feature high on the list at most centres.
