Older people with stronger muscles are at reduced risk of developing Alzheimer's disease.

Florida QB and 2007 Heisman Trophy winner Tim Tebow is the latest star to suffer a concussion in the tough sport of football. Wildcats defensive end Taylor Wyndham hit hard in the chest on third-and-6 play from the Kentucky 9. As Tebow fell to the ground, the back of his head hit Gators tackle Marcus Gilbert's knee. For now, he appears to be OK, but concussions are a worry in all levels of football, as this new study clearly notes.

Money management difficulties may be a clue that predicts the onset of Alzheimer's disease.

Gothenburg researchers have discovered a previously unknown substance in spinal fluid that can be used to diagnose Alzheimer's disease. The findings, described in a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden, will also be useful in research on new medications.

Getting a cold, stomach bug or other infection may lead to increased memory loss in people with Alzheimer's disease, according to research published in the September 8, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.

A drug now used to treat cancer may also be able to restore memory deficits in patients with Alzheimer's disease, according to a new study conducted by scientists at Columbia University Medical Center, which appeared in the September issue of The Journal of Alzheimer's Disease: Volume 18:1.

A combination of proteins in the cerebrospinal fluid can reliably identify which patients with early symptoms of dementia will subsequently develop full-blown Alzheimer's disease, a research team at the University of Gothenburg, Sweden, has found in a major international study. The results were published in this week's edition of the Journal of the American Medical Association (JAMA).

Over five million Americans and an estimated 26 million people globally live with the fatal brain disease known as Alzheimer’s. According to leading health and insurance experts the disease progressively destroys brain cells and victims suffer from memory problems and difficulties with thought processes.

A study led by Johns Hopkins and Utah State University researchers suggests that a particularly close relationship with caregivers may give people with Alzheimer's disease a marked edge over those without one in retaining mind and brain function over time. The beneficial effect of emotional intimacy that the researchers saw among participants was on par with some drugs used to treat the disease.

Research carried out at the Hebrew University of Jerusalem has resulted in a promising approach to help treat Alzheimer's disease in a significant proportion of the population that suffers from a particularly rapid development of Alzheimer's disease.

Barrow Neurological Institute researchers have identified a novel receptor in the brain that is extremely sensitive to beta-amyloid peptide (AB) and may play a key role in early stages of Alzheimer's disease.

A large study of patients with mild cognitive impairment revealed that results from cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease.
