Evidence Links Protein Damage to Neurodegenerative diseases like Parkinson's and Alzheimer's

Neurodegenerative diseases - including Parkinson's, Alzheimer's, Diffuse Lewy body disease, and Multiple System Arophy - are collectively called synucleinopathies. Most commonly they become symptomatic due to a deficiency of a specific neurotransmitter - in the case of Parkinson's it is dopamine. When the neurons that produce these chemicals die or become impaired, which occurs with oxidation, th...

Miracle cure for Alzheimer’s around the corner

Alzheimer’s Disease, one of the most common and perhaps the most dreadful kind of Dementia, where there is degeneration of the brain tissue, might at last have the much awaited miracle cure round the corner. If proven successful it would be an enormous breakt...

Vaccine for Alzheimer’s diseas

Researchers developing a vaccine against Alzheimer’s disease have shown that it seems to stop mice with the condition losing their memory. The results boost hopes that such vaccines could delay or prevent similar symptoms in people. ....The vaccines reduces the build-up of protein deposits in mouse brains -the other major indicator of Alzheimer’s diseases. The pharmaceutical company Elan, based i...

Alzheimer cure

Restoring a signalling molecule to the brain reverses Alzheimer-like damage in mice. In both Alzheimer's disease and Down's syndrome, a group of brain cells called the basal forebrain cholinergic neurons shrivels and dies. The brain chemical, acetylcholine, which these neurons produce, is lost and, since it is involved in learning and memory, results in cognitive decline. ....In London and Calif...

Decrease in testosterone levels lead to Alzheimer's

Suppression of testosterone levels in men with testicular cancer may inadvertently increase the risk of Alzheimer’s disease, warn US researchers.....A research team from North Carolina University has found that when circulating testosterone levels go down, a high rise in levels of amyloid – the protein implicated in Alzheimer’s disease – occurs. They suggest that this phenomenon might explain why...

Smoker's are prone to Alzheimer's

Smokers are more than twice as likely to develop Alzheimer's Disease as people who have never smoked, according to new research. ..The study - the largest ever of its kind and the first major research to look at people before they develop Alzheimer's - followed 5,369 men and women aged 57 and over. ....None of the people had Alzheimer's, the most common form of dementia, before the study by the...

Over-The-Counter Drugs May Prevent Alzheimer's

Certain over-the-counter pain relievers commonly used to counter the pain and inflammation of rheumatoid arthritis also may cut the risk of getting Alzheimer's disease. In addition to their anti-inflammatory properties, the drugs seem to selectively reduce levels of a harmful protein linked to the neurodegenerative disease. The study developed from research suggesting that people taking certain N...

Prefiguring Alzheimer's disease

Mild memory loss is often an indicator of Alzheimer's disease and is connected to the same brain pathology. There has been a lot of controversy over the implications of mild cognitive decline the loss of memory and certain other aspects of mental function,// like problem solving and planning.Some people think it is a normal part of aging, others that it is an early sign of Alzheimer's dementia, w...

Blood Pressure An Early Warning Sign Of Alzheimer’s Disease

An early warning sign of developing Alzheimer’s disease is a drop in blood pressure, say researchers, according to new research.// ..Results from previous research on the association between blood pressure and Alzheimer’s disease have been conflicting.

Diet combined to Alzheimer's disease

Researchers at the Colulmbia University found that eating more calories and fats may increase the risk of developing Alzheimer's disease in some people. Previous research has shown that mice and rats on a restricted diet tend to live longer. //Researchers feel this is because of fewer destructive molecules formed during the breakdown of food and oxygen. These destructive molecules, known as free...

Oral memory indicates future Alzheimer's patients

A word recall test is able to differentiate those who will get Alzheimer's disease from healthy older people. Alzheimer's disease is chiefly a condition of older people - so we can expect an increase in the number of cases as the population ages.// Treatments are now available and they seem to work best if they start early. This means early diagnosis is a priority. ....Researchers at the Univers...

Shunt for Alzheimer's Disease

According to a new research it is observed that a surgically implanted shunt could help slow the progression of Alzheimer's disease. The research focuses on draining cerebrospinal fluid. This type of shunting was first used in 1970 for dementia, however the procedure was no longer used// when there seemed to be a high incidence of side effects related to the shunts. Recent studies of this type of...

New Cholesterol gene linked to Alzheimer's

The findings of a new study published in January's Archives of Neurology suggests that a new gene called CYP46 may play a role in some cases of Alzheimer's disease. A variation in the gene, which is involved in the production of an enzyme that helps break down excess cholesterol in the brain, may result in the buildup of cholesterol and a gummy protein// called beta amyloid, in the brain. ....Ear...

New imaging technique for tracking Alzheimer's

Researchers, for the first time, have shown, using a new imaging technique based on Magnetic Resonance Imaging(MRI), how Alzheimer's attacks the brain over time. Until now, MRI was used to show how Alzheimer's disease shrinks the hippocampus, a key area of the brain for memory and learning. And post-mortem studies revealed how the disease devastates even larger brain areas. This is the first time...

Likely reason which makes analgesics work against Alzheimer's

Pain killers like ibuprofen or naproxen have long been known to help people protect themselves against Alzheimer's disease. Now, researchers from the University of California have found a possible reason as to why this might be so. These scientists had previously developed a marker molecule called FDDNP that was used to detect the presence of plaque. Plaque is a protein deposit in the brain that...

A drug in vogue to deccelerate the course of Alzheimer's

Alzheimer’s disease continues to fuel research, as the incidence is likely to increase in the future. A new drug has been developed to slow the course of Alzheimer's disease.

Learning and memory are the fields, which are enabled by the chemical glutamate....

Lithium May help in Alzheimer's Disease

Alzheimer's affects about 12 million people worldwide. Lithium may have a potential role in treating Alzheimer's.

Painkillers may protect against Alzheimer's disease

Common painkillers may lower the risk of developing Alzheimer's disease, and the longer they are taken the greater the benefit, scientists said on Friday. They reviewed 15 studies that examined the effect of painkillers, known as non-steroidal anti-inflammatory drugs (NSAIDs), and found people who take them are less likely to develop the illness, which is the leading cause of dementia in the elde...

Adding Fish to Diet May Reduce Risk of Alzheimer's
