Study finds mix of disease processes at work in brains of most people with dementia

...strokes, Parkinson’s disease, hemorrhages, tumors, traumatic brain injury or others. Comparison of the clinical and autopsy results showed that only 30 percent of people with signs of dementia had Alzheimer’s disease alone. By contrast, 42 percent of the people with dementia had Alzheimer’s disease with in...

Researchers use MRI to predict recovery after spinal cord injury

... Dr. Fehlings’ study included 100 patients with traumatic cervical SCI. The group consisted of 79 men and 21 women between the ages of 17 and 96. Complete motor and sensory SCI was seen in 26 patients, incomplete SCI was seen in 51 patients, and 22 patients were neurologically intact upon admission. One pat...

Mice with a migraine show signs of brain damage

...nomenon contributes to injury from stroke and from traumatic brain injury as well as migraine. While it’s been widely recognized that CSD underlies some migraines, Nedergaard’s team linked the phenomenon for the first time to both severe hypoxia and to damage to brain cells. As a result of CSD, the team fou...

Amateur boxing linked to brain cell injury

... 20 percent of professional boxers develop chronic traumatic brain injury, according to background information in the article. Some studies have suggested that amateur boxers also damage their nervous systems, but because their shorter bouts allow fewer blows to the head and because they must wear safety equi...

New mechanism underlying pain found

...following a nerve injury, typically results from a traumatic injury, an infection or disease, or surgery, and can persist long after the initial injury has healed. Millions of people worldwide suffer some form of neuropathic pain, and the current treatment options are limited or inadequate for many people. The...

"The standard paradigm has been the cornea is avascular because it has lots of anti-angiogenic molecules and it does," Balamurali Ambati said. "But knockdown of any of the other molecules does not ...
