Calcium supplements linked to post-stroke dementia in women
Conclusion The media paint this as a troubling study for older women who take calcium to strengthen their bones. However the small size of the study (only 98 women took calcium supplements, and only 14 of those got dementia) and its observational nature mean that we cannot rely on the results. As the researchers mention, it is possible that those taking supplements were less healthy than those that didn't in some unmeasured way. Further research may improve our confidence in these results. Broken bones are not a trivial matter for older people – a broken hip can be the difference between being able to live independentl...

Calcium/Calmodulin –Dependent Protein Kinase II in Cerebrovascular Diseases
AbstractCerebrovascular disease is the most common life-threatening and debilitating condition that often leads to stroke. The multifunctional calcium/calmodulin-dependent protein kinase II (CaMKII) is a key Ca2+ sensor and an important signaling protein in a variety of biological systems within the brain, heart, and vasculature. In the brain, past stroke-related studies have been mainly focused on the role of CaMKII in ischemic stroke in neurons and established CaMKII as a major mediator of neuronal cell death induced by glutamate excitotoxicity and oxidative stress following ischemic stroke. However, with growing underst...

Subclinical Vascular Composites Predict Clinical Cardiovascular Disease, Stroke, and Dementia: The Multi-Ethnic Study of Atherosclerosis (MESA)
CONCLUSIONS: Subclinical vascular composites of arteriosclerosis and atherosclerosis may be useful biomarkers to inform the vascular pathways contributing to events of CVD, CHD, stroke, and dementia.PMID:37205504 | PMC:PMC10187443 | DOI:10.1101/2023.05.01.23289364

Mystery of why arteries harden may have been solved, say scientists
Study finds calcium deposits are triggered by molecule produced by damaged cellsThe mysterious mechanism behind the hardening of arteries may have been solved, researchers have revealed, in a study that also suggests the first potential preventive drug for the condition linked to heart attack, dementia and stroke.Arteries harden as calcium becomes deposited in the elastic walls of the vessels, a process that happens as we age and is exacerbated for patients with diabetes or kidney disease. Stiffening can also occur as calcium becomes deposited in fatty plaques in the arteries – a condition called atherosclerosis.Continue reading...

Association of vitamin D metabolites with cognitive function and brain atrophy in elderly individuals - the Austrian stroke prevention study
CONCLUSIONS: Vitamin D deficient individuals appear to have a modest reduction of memory function without structural brain atrophy. Future studies should explore if vitamin D supplementation can improve cognitive function.PMID:33825696 | DOI:10.18632/aging.202930

Recurrent Transient Ischemic Attack Induces Neural Cytoskeleton Modification and Gliosis in an Experimental Model
AbstractTransient ischemic attack (TIA) presents a high risk for subsequent stroke, Alzheimer ’s disease (AD), and related dementia (ADRD). However, the neuropathophysiology of TIA has been rarely studied. By evaluating recurrent TIA-induced neuropathological changes, our study aimed to explore the potential mechanisms underlying the contribution of TIA to ADRD. In the current study, we es tablished a recurrent TIA model by three times 10-min middle cerebral artery occlusion within a week in rat. Neither permanent neurological deficit nor apoptosis was observed following recurrent TIA. No increase of AD-related biomarker...

Correlation Between Intracranial Arterial Calcification and Imaging of Cerebral Small Vessel Disease
Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Microglial Activation Modulated by P2X4R in Ischemia and Repercussions in Alzheimer ’s Disease
There are over 80 million people currently living who have had a stroke. The ischemic injury in the brain starts a cascade of events that lead to neuronal death, inducing neurodegeneration which could lead to Alzheimer’s disease (AD). Cerebrovascular diseases have been suggested to contribute to AD neuropathological changes, including brain atrophy and accumulation of abnormal proteins such as amyloid beta (Aβ). In patients older than 60 years, the incidence of dementia a year after stroke was significantly increased. Nevertheless, the molecular links between stroke and dementia are not clearly understood but could be r...

The Ca2+-gated channel TMEM16A amplifies capillary pericyte contraction and reduces cerebral blood flow after ischemia
Pericyte-mediated capillary constriction decreases cerebral blood flow in stroke after an occluded artery is unblocked. The determinants of pericyte tone are poorly understood. We show that a small rise in cytoplasmic Ca2+ concentration ([Ca2+]i) in pericytes activated chloride efflux through the Ca2+-gated anion channel TMEM16A, thus depolarizing the cell and opening voltage-gated calcium channels. This mechanism strongly amplified the pericyte [Ca2+]i rise and capillary constriction evoked by contractile agonists and ischemia. In a rodent stroke model, TMEM16A inhibition slowed the ischemia-evoked pericyte [Ca2+]i rise, ...

High Blood Pressure and Diabetes Are Linked. Here ’ s How to Reduce Your Risk for Both
High blood pressure—also known as hypertension—and Type 2 diabetes are two of the most common medical conditions in the U.S. Unfortunately, they often occur together. Some research has found that 85% of middle-aged or older adults who have Type 2 diabetes also have hyper­tension, and both conditions elevate a person’s risk for heart disease, stroke, and kidney disease. These increased risks are significant, and in some cases grave. Researchers have found that people with Type 2 ­diabetes are up to four times more likely to develop cardiovascular disease than those who don’t have the conditio...

Conclusion: This novel technology discriminates and quantifies subtle differences in behavior and neurological impairments in subjects afflicted with neurological injury/disease. KINARM assessments can be incorporated into multi-center trials (e.g., monitoring stroke motor recovery: NCT02928393). Further studies will determine if KINARM Labs can demonstrate a clinical effect with fewer subjects over a shorter trial period. Disclosures/funding: Dr. Stephen Scott is the inventor of KINARM and CSO of BKIN Technologies.   Multiplexed mass spectrometry assay identifies neurodegeneration biomarkers in CSF Presenter: Chelsky...
