For those with Obsessive-Compulsive Disorder, the unfamiliar can be paralyzing and they need more ritual and routine to offset the chaos of the outside world. A new study examined how endocannabinoids -- natural messengers in the body chemically similar to the active compound in marijuana, and known to generally reduce the activity of neurons -- play a role in how the brain controls this fundamental process.
With individuals afflicted with Kennedy's disease, muscle cells and motor neurons die over the years because they accumulate a protein that is mutated. Researchers have discovered that this protein has a self-protective mechanism through which the effects of the mutation are delayed.
Muhammad Ali has been lauded for his oratorical skill, his activism and certainly his boxing. Yet for decades it's been believed that even one of the greatest boxers could not beat back the head trauma that led to the Parkinson's disease he suffered from since the 1980s.
