Diabetes patients have a high production of glucose, which can cause cellular damage to blood vessels.
Matt Whiteman, PhD, Senior Lecturer, Institute of Biomedical and Clinical Science, Peninsula Medical School, South West of England has found that resveratrol, a compound naturally found in grape skin, can protect against cellular damage to blood vessels caused by high [...]

Rheumatoid arthritis is associated with an increased risk of hardening of the arteries (atherosclerosis) and cardiovascular diseases. The causes are unknown, but the disturbed balance of blood fats may be part of the explanation.
Johan Frostegård, professor, Karolinska Institute, found that a gluten-free vegan diet reduces cardiovascular risk in people with rheumatoid arthritis. Participants in the year [...]

As baby-boomers age their risks of developing dementia, Alzheimer’s disease, or heart disease increases. Stroke and dementia are the most widely feared age-related neurological diseases, and are also the only neurological disorders listed in the 10 leading causes of disease burden.
Researchers from Boston University School of Medicine (BUSM) followed 2,794 participants of the Framingham Heart [...]

Alzheimer’s disease creates an accumulation of amyloid plaque deposits, which is composed primarily of the neurotoxic beta-amyloid peptide. The amyloid peptides are “cut” out from a larger protein called amyloid precursor protein (APP), then bind together to form plaques in the memory area of the brain.
Vivian Y.H. Hook, PhD, professor, Skaggs School of Pharmacy and [...]

Alzheimer’s disease claims tens of thousands of American lives each year. A positive diagnosis, of the disease, is a process of eliminating all other possible causes with an incorrect diagnosis estimated to occur 10% of the time. It is only after someone dies can a pathologists examine slices of the brain under a microscope to positively identify [...]

A recent study found that Alzheimer’s patients have an elevated level of magnetic iron oxides in the area of the brain that is affected by the disease.
Jon Dobson, professor, Keele University, Staffordshire, UK, looked at the brain tissue from 11 Alzheimer’s disease patients and 11 age-matched control subjects. For the first time it shows that [...]

Researchers suspect that Alzheimer’s disease (AD) might be caused by the same mechanism that helps a healthy mind from being mired by minutia–like remembering what you ate for lunch for the past 8 Tuesdays–but for Alzheimer’s patients the mechanism has gone into overdrive and with it stuck in reverse.
In a normal brain there is a continual [...]

Brain receptors TRPV1 (transient receptor potential vanilloid subtype) have been known to affect sensations of pain and respond not only to heat, but also to capsaicin–the ingredient that gives chili peppers their spicy kick. Until now no one had linked TRPV1 to memory.
Julie Kauer, professor of medical science, Department of Molecular Pharmacology, Brown University, and her co-researchers, [...]

Every year an estimated 60,000 new cases of the neurodegenerative disease, Parkinson’s, are diagnosed in the U.S. Currently, an estimated 1½ million Americans have Parkinson’s disease.
Diagnosis of Parkinson’s is done solely based on the patient’s symptoms. Unfortunately, conditions such as multi-system atrophy or progressive suprancuclear palsy look a lot like Parkinson’s. As a result approximately [...]

The leading cause of cognitive impairment in the U.S. elderly is Alzheimer’s disease. Because it is so common it is not unusual for both parents to develop the disease and presumably their offspring would be more likely to carry any genes associated with Alzheimer’s disease.
Suman Jayadev, MD, University of Washington, Seattle, and co-researchers, studied 111 families [...]
