The most definitive classification systems for dementia are based on the underlying pathology which, in turn, is categorized largely according to the observed accumulation of abnormal protein aggregates in neurons and glia. These aggregates perturb molecular processes, cellular functions and, ultimately, cell survival, with ensuing disruption of large-scale neural networks subserving cognitive, behavioural and sensorimotor functions. The functional domains affected and the evolution of deficits in these domains over time serve as footprints that the clinician can trace back with various levels of certainty to the underlying neuropathology...

It is well known that the survival is higher in women compared to men and women have a better survival prognosis than men in some pathologies such as vascular dementia (VD). Our previous reports showed that the spontaneously hypertensive (SH) rat, an animal model of VD, exhibited dendritic atrophy of pyramidal neurons of the dorsal hippocampus (DH) and the prefrontal cortex (PFC) at 8 months of age. Cerebrolysin (CBL), a neurotrophic peptide mixture, reduces dendritic atrophy and improves the memory process in aged rats...

BACKGROUND: A lot of attention has been paid to the relationship of blood pressure and dementia because epidemiological research has reported conflicting evidence. Observational data has shown that midlife hypertension is a risk factor for cognitive decline and dementia later in life, whereas there is evidence that low blood pressure is predictive in later life. The aim of the present study was to examine the association between dementia and blood pressure measured up to 27 years (mean 17...

Association of telomere shortening with overall dementia or Alzheimer's disease is described controversially and the pathophysiologic relevance is unclear. Whether patients, suffering from pure probable Alzheimer's disease or pure vascular dementia, have shorter leukocyte telomeres than cognitively healthy controls was determined. Leukocyte telomere lengths (LTLs) of 597 participants of the VITA study (longitudinal community-based age-cohort [mean 75.7 (±0.45) years] study: 243 male; 578 non-demented at baseline) were compared with different aspects of cognition, risk factors of dementia and survival...

BACKGROUND: Vascular risk factors have been proposed as important targets for the prevention of dementia. As lipid fractions represent easily modifiable targets, we examined the longitudinal relationship of baseline lipid fractions with 13-y incident dementia and its subtypes (Alzheimer disease [AD] and mixed or vascular dementia) in older community-dwelling persons. METHODS AND FINDINGS: Non-institutionalized persons aged 65+ y (n = 9,294) were recruited for the Three-City Study (3C Study), a population-based cohort study from the electoral rolls of the cities of Dijon, Bordeaux, and Montpellier, France, between March 1999 and March 2001...

We examined whether apolipoprotein E (APOE) status interacts with vascular risk factors (VRFs) to predict the progression of white matter hyperintensities (WMHs) on brain MRI scans over a specific period of life in older age when the risk of dementia increases. At age 73 years, baseline VRFs were assessed via self-reported history of diabetes, hypertension, smoking, and hypercholesterolemia, and via objective measures of blood HbA1c, body mass index, diastolic and systolic blood pressure, and blood high-density lipoprotein to total cholesterol (HDL) ratio...

#12
Ming Hu, Zhijuan Liu, Peiyuan Lv, Hebo Wang, Yifei Zhu, Qianqian Qi, Jing Xu
The Akt/CREB signalling pathway is involved in neuronal survival and protection. Autophagy is also likely to be involved in survival mechanisms. Nimodipine is an L-type calcium channel antagonist that reduces excessive calcium influx during pathological conditions (contributing to its neuroprotective properties). However, the potential role of nimodipine in autophagic and Akt/CREB signalling is not well understood. In addition, little is known about the relationship between autophagic and Akt/CREB signalling...

BACKGROUND AND PURPOSE: Stroke is a risk factor for dementia, but the risk of dementia after different stroke types is poorly understood. We examined the long-term risk of dementia among survivors of any first-time stroke and of first-time ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. METHODS: We conducted a 30-year nationwide population-based cohort study using data from Danish medical databases (1982-2013) covering all Danish hospitals...

Prolonged ischemia can result in apoptotic death of vascular endothelial cells and lead to ischemic vascular diseases including vascular dementia, arteriosclerosis and brain oedema. Finding protective strategies to prevent this is therefore an urgent mission. Recent studies have shown that dysregulation of microRNAs (miRNAs) can lead to imbalance of Bcl-2 family proteins and mitochondrial dysfunction, leading to further damage of vascular cells under ischemic conditions. However, whether miRNAs can be used as a drug target for treating vascular diseases is not fully understood...

Some TTR mutants target the central nervous system (CNS). Familial amyloid polyneuropathy (FAP) with leptomeningeal involvement has been described in 9% of transthyretin (TTR) mutations and in valine for methionine at position 30 (V30M) patients. These individuals present dementia, ataxia, brain hemorrhages and focal neurological episodes (FNEs). FNEs occurred also in V30M FAP patients with longer disease duration, who have undergone liver transplant to remove the source of plasma mutant TTR as a form of treatment...

REVIEW
Walter Pirker, Regina Katzenschlager
Human gait depends on a complex interplay of major parts of the nervous, musculoskeletal and cardiorespiratory systems. The individual gait pattern is influenced by age, personality, mood and sociocultural factors. The preferred walking speed in older adults is a sensitive marker of general health and survival. Safe walking requires intact cognition and executive control. Gait disorders lead to a loss of personal freedom, falls and injuries and result in a marked reduction in the quality of life. Acute onset of a gait disorder may indicate a cerebrovascular or other acute lesion in the nervous system but also systemic diseases or adverse effects of medication, in particular polypharmacy including sedatives...

Importance: A growing body of evidence supports a link between androgen deprivation therapy (ADT) and cognitive dysfunction, including Alzheimer disease. However, it is currently unknown whether ADT may contribute to the risk of dementia more broadly. Objective: To use an informatics approach to examine the association of ADT as a treatment for prostate cancer with the subsequent development of dementia (eg, senile dementia, vascular dementia, frontotemporal dementia, and Alzheimer dementia)...

OBJECTIVE: Available data on the prognostic role of blood pressure in older subjects with cognitive impairment are still scarce. We recently showed that tight control of blood pressure may be associated with a greater progression of cognitive impairment in the short term. Aim of this study is to evaluate the long term association of clinical and ambulatory blood pressure (BP) and antihypertensive drugs (AHD) with survival and desease progression in older subjects with cognitive impairment...

BACKGROUND AND PURPOSE: Improved short-term survival after stroke has necessitated quantifying risk and risk factors of long-term sequelae after stroke (ie, recurrent stroke and dementia). This risk may be influenced by exposure to cardiovascular risk factors before the initial stroke. Within the population-based Rotterdam Study, we determined the long-term risk of recurrent stroke and dementia, and the proportion of recurrent strokes and poststroke dementia cases that are attributable to prestroke cardiovascular risk factors (ie, the population attributable risk)...

INTRODUCTION: Patients surviving stroke without immediate dementia are at high risk of delayed-onset dementia. Mechanisms underlying delayed-onset dementia are complex and may involve vascular and/or neurodegenerative diseases. METHODS: Dementia-free patients with stroke and/or transient ischemic attack (TIA; n = 919) were studied for 3 years prospectively, excluding those who developed dementia 3 to 6 months after stroke and/or TIA. RESULTS: Forty subjects (4...
