Exposure to second-hand smoke could increase the risk of developing dementia and other forms of cognitive impairment, according to research published on British Medical Journal online.
A possible link between active smoking and cognitive impairment has already been established and previous findings also suggest that second-hand smoke exposure could be linked to poor cognitive performance in [...]

People with more B12 had six times less brain shrinkage
Vitamin B12, a nutrient found in meat, fish and milk, may protect against brain volume loss in older people, according to a study published in the journal  Neurology®.
For the study, 107 people between the ages of 61 and 87 underwent brain scans, memory testing and physical [...]

Two studies published in the  American Journal of Clinical Nutrition add more evidence of the importance of omega-3 fatty acids in your diet.
One study from Norway found that the more fish folks ate, the better they did on cognitive performance tests. This is called “dose-dependence” in the research jargon.
The study involved 2031 participants, 55% women, [...]

Researchers find wide array of brain food, smarter naturally.
A good diet is known to be reduce the risk of all the big illnesses; cancer, heart disease, diabetes.
New research from scientists at MIT provides evidence that getting smart about what we eat can improve brain function and intelligence. According the research, dietary nutrients found in a [...]

A loss of protein function in neurons may lead to Alzheimer’s Disease.
Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively “puts the brakes” on the dementia that comes with Alzheimer’s disease (AD). When the brakes fail, dementia results.
It is estimated [...]

Scientists have long questioned whether the abundant amounts of amyloid plaques found in the brains of patients with Alzheimer’s actually caused the neurological disease or were a by-product of its progress. In a new study, using new research techniques, scientists have shown that a two-molecule aggregate (or dimer) of beta-amyloid protein fragments may play a [...]

Cannabis and certain prescribed drugs can harm the developing brain according to research from
the University of Aberdeen in Scotland. show that the influence of this crucial signalling system in the developing brain is much more widespread than was originally thought.
The research, published in the Proceedings of the National Academy of Sciences, of the United States [...]

After a stroke, even unaffected areas of the brain are at risk – depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die. This has previously been observed only in animal studies.
 
A clinical study at the university hospitals [...]
