HMG-CoA reductase inhibitors ("statins") are commonly prescribed for the treatment of dyslipidemia and prevention of any complications arising from this disease. The Food and Drug Administration recently published enhanced warnings for statin use, including the possible relationship between statins and cognitive impairment, especially in the elderly. Significant cognitive decline associated with statin use in elderly patients with Alzheimer's disease has also been reported recently. However, the 2013 American College of Cardiology/American Heart Association blood cholesterol guidelines stated that no evidence is available supporting the conclusion that statins cause an adverse effect on cognition or risk of dementia. Because of the increasing number of elderly patients with dementia, this relationship needs to be examined. This article will review cognitive changes associated with statin use in elderly patients with dementia and offer clinical recommendations.

In addition to hypertension, dyslipidemia, atherosclerosis, and diabetes, a sedentary lifestyle plays a pivotal role in cerebro- and cardiovascular disease and progressive cognitive decline, including vascular dementia and Alzheimer's disease. The present study investigated whether controlling the key risks and participating in physical activity have a beneficial impact on these disorders. Elderly volunteers were enrolled in a 3-month program that consisted of structured exercise three times per week. The daily routine, medical treatment, and vital parameters were evaluated and correlated with the subjects' neuropsychiatric status. High blood pressure was found in 40% of the participants, with no significant differences between the sexes. A higher proportion of females (55%) than males (18%) forgot to take their medication during the observation period. Significant negative correlations were found between Mini-Mental State Examination (MMSE) scores and age, lack of a caregiver, and increased pulse rate before or after exercise. These results suggest that the presence of home assistance and subsequent improvement in medication compliance, vital parameter optimization, and regular physical activity may yield better MMSE results and a lower risk for cerebro- and cardiovascular disease.

Vascular diseases such as stroke, myocardial infarction, most causes of heart failure, dementia, peripheral arterial disease, certain kidney, and many lung and eye conditions are a result of disorders in the blood vessels (large and small) throughout the entire human body. Vascular diseases are the leading cause of preventable death and disability in Canada. Most vascular diseases share common risk factors (high blood pressure, diabetes, dyslipidemia, and obesity), which can be influenced by modifiable health behaviours such as unhealthy diet, smoking, lack of physical activity, and stress. Ninety percent of Canadians face an increased risk, which could be modified by managing these health behaviours and risk factors. Canada's aging population, combined with alarming trends in obesity, physical inactivity, high blood pressure, and diabetes are expected to further increase the social and economic effect of vascular diseases in the coming decades, unless there are major changes in health policy. Even more concerning is the increase in vascular risk factors among Canada's youth, and ethnically diverse populations. Vascular diseases affect not only the patient, but also place burdens on their spouses, families, friends, and communities. Tremendous potential exists to reduce the effects of vascular diseases through healthy public policy, supporting Canadians to make healthy lifestyle changes, and coordinating efforts across the continuum of care in a patient-focused manner. Vascular health requires partnerships for action across many sectors including government, health care practitioners, academia, not-for-profit organizations, and the private sector. The health sector alone cannot solve this problem.

Alzheimer's disease (AD) is the most common cause of dementia, accounting for more than half of cases with cognitive impairment. With numbers of patients expected to rise sharply over the following years in parallel with the ageing of population, there is intense clinical interest in discovering modifiable risk factors that may contribute to the increasing prevalence of AD. Accumulating data from in vitro and epidemiological studies have highlighted the vascular component of AD and raised hope that treatment of vascular risk factors could eventually lead to primary prevention of AD. Among all the possible pathologic processes that have been tested for an association with AD, diabetes, hypertension and dyslipidemia are the most prominent. Here, we will briefly review the data highlighting a potential correlation of these diseases with AD. Then, we will present observational studies and clinical trials that assessed the impact of their respective approved medical therapies on AD incidence. We conclude by providing clinical information for the physician on potentially effective and non-effective medical treatments. Further research is ongoing and time will show whether AD will cease to be considered a pure, non-preventable neurodegenerative process or whether vascular risk factor management may also result in primary AD prevention.

Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors that includes obesity, diabetes, and dyslipidemia. Accumulating evidence implies that MetS contributes to the development and progression of Alzheimer's disease (AD); however, the factors connecting this association have not been determined. Insulin resistance (IR) is at the core of MetS and likely represent the key link between MetS and AD. In the central nervous system, insulin plays key roles in learning and memory, and AD patients exhibit impaired insulin signaling that is similar to that observed in MetS. As we face an alarming increase in obesity and T2D in all age groups, understanding the relationship between MetS and AD is vital for the identification of potential therapeutic targets. Recently, several diabetes therapies that enhance insulin signaling are being tested for a potential therapeutic benefit in AD and dementia. In this review, we will discuss MetS as a risk factor for AD, focusing on IR and the recent progress and future directions of insulin-based therapies.

Vascular risk factors (e.g. hypertension, dyslipidemia and diabetes) are well known risk factors for Alzheimer' disease. These vascular risk factors lead to vascular brain injuries, which also increase the likelihood of dementia. The advent of amyloid PET imaging has helped establish that vascular risk factors also lead to Alzheimer's disease via pathways that are independent from vascular brain injuries, at least, when vascular brain injuries are measured as white matter lesions and infarcts. While vascular brain injuries (white matter lesions and infarcts) do not seem to influence amyloid pathology, some evidence from amyloid imaging suggests that increased vascular risk is related to increased amyloid burden. Furthermore, while vascular brain injuries and amyloid have an additive and independent impact on brain integrity, vascular risk factors might potentiate the impact of amyloid on cortical thickness on brain regions vulnerable to Alzheimer's disease. New research should further explore and confirm, or refute, possible interactions between amyloid and vascular risk factors on brain integrity and cognition. Neuroimaging tools used to assess vascular brain integrity should also be expanded. Measuring cortical blood flow or damage to the capillary system might, for instance, give insight about how vascular risk factors can be associated to amyloid burden and impact. These findings also stress the need for monitoring vascular risk factors in midlife as a strategy for Alzheimer's disease prevention.

Alzheimer dementia (AD) is an important clinical problem that appears to be closely tied to comorbid cardiovascular disease, making it a relevant topic for the clinical cardiologist. Determinants of cardiovascular health, especially midlife dyslipidemia, are associated with an increased risk of dementia based on molecular and epidemiologic data. Given the potential role of dyslipidemia in the development of dementia, statins have been investigated as potential therapeutic options to slow or prevent disease. This review discusses the role of dyslipidemia and other cardiovascular risk factors in the pathogenesis of AD, with a focus on the existing evidence for the use of statin medications in the treatment and prevention of AD from observational studies and randomized clinical trials. Clinical questions for the practicing cardiologist are addressed.

Alzheimer's disease (AD) is the most common cause of dementia in people over 65 years of age. At present, treatment options for AD address only its symptoms, and there are no available treatments for the prevention or delay of the disease process. Several preclinical and epidemiological studies have linked metabolic risk factors such as hypertension, obesity, dyslipidemia, and diabetes to the pathogenesis of AD. However, the molecular mechanisms that underlie this relationship are not fully understood. Considering that less than 1% of cases of AD are attributable to genetic factors, the identification of new molecular targets linking metabolic risk factors to neuropathological processes is necessary for improving the diagnosis and treatment of AD. The dysregulation of microRNAs (miRNAs), small non-coding RNAs that regulate several biological processes, has been implicated in the development of different pathologies. In this review, we summarize some of the relevant evidence that points to the role of miRNAs in metabolic syndrome (MetS) and AD and propose that miRNAs may be a molecular link in the complex relationship between both diseases.

In this communication, we report a patient with familial amyotrophic lateral sclerosis (ALS) associated with a familial dyslipidemia. Genetic analysis revealed a novel heterozygous valosin-containing protein (VCP) mutation (c.466G>T (p.G156C)). The other gene analysis also disclosed a known homozygous LCAT mutation (c.101C>T (p.P10L)). VCP gene mutation shown should be responsible for familial ALS because of following reasons. The patient's father also was also affected by ALS. The VCP gene mutation (p.G156C) in the patient was located in the vicinity of a site frequently associated with pathogenic VCP variants. The same amino acid transformation as that of this patient has been reported to be involved in the pathogenesis of inclusion body myopathy with Paget's disease of the bone and frontotemporal dementia. This is the first case report of rare association of ALS with VCP mutation and dyslipidemia with LCAT mutation.

The increasing prevalence of Metabolic Syndrome (MetS), defined as the clustering of abdominal obesity, dyslipidemia, hypertension, and hyperglycemia, appears to be driving the global epidemics cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). Nutrition has a major impact on MetS and plays an important role in the prevention, development, and treatment of its features. Structural and functional alterations in the vasculature, associated with MetS, might form the link between MetS and the increased risk of developing CVD and T2DM. Not only does the peripheral vasculature seem to be affected, but the syndrome has a profound impact on the cerebral circulation and thence brain structure as well. Furthermore, strong associations are shown with stroke, cognitive impairment, and dementia. In this review the impact of nutrition on the individual components of MetS, the effects of MetS on peripheral and cerebral vasculature, and its consequences for brain structure and function will be discussed.
