What Led to Muhammad Ali’s Parkinson’s Disease? Muhammad Ali––who lived with Parkinson’s disease since his diagnosis in 1984––died on Friday, June 3, at the age of 74. Experts debate whether repeated head trauma during his boxing career led to his early onset of Parkinson’s. Neurologists can’t say for sure, but many say that head trauma increases the risk. Read more about the controversy. Groundbreaking New Study Shows How Blast Exposure Affects the Brain For many years, people have known that wartime exposure to blasts can affect the brain. Called “shell shock” a hundred years ago, it’s now typically thought of as a type of traumatic brain injury. But scientists weren’t sure what, exactly, a blast did to the brain. Now, a new study that looked at the autopsied brains of eight soldiers shows that blast exposure creates scarring in certain areas of the brain, usually where two different types of matter intersect (such as between gray and white matter). Learn more about the implications of this finding. Stem Cell Experiment Helps Stroke Patient Walk A promising yet small-scale study conducted by researchers at Stanford saw seven out of 18 stroke patients walk again after surgeons drilled holes directly into their brains and injected stem cells that were harvested from the bone marrow of adult donors. This is an encouraging start, but there’s a lot more work to be done. Find out more about this research. The Brain as a Multisensory Processor Researchers out of Bielefeld University and the Max Planck Institute for Biological Cybernetics wanted to understand how humans combine visual and auditory information. Their findings, published in Nature Communications, are noteworthy because they mayopen new clinical perspectives for neurological syndromes that are associated with multisensory impairments. Learn more Can Online Illusions Be Dangerous to Your Health? Akiyoshi Kitaoka, a psychology professor of visual perception and visual illusion at Ritsumeikan University in Kyoto, Japan, warns that the illusions he creates and shares online can be dangerous for some viewers. Why? In short, it’s because sometimes our brains can’t handle the information it gets from our eyes. Read this article to find out more, and to check out some of Kitaoka’s illusions. But if you start getting dizzy, cover your eyes with your hand and look away from the screen! Book of the Month: Into the Magic Shop: A Neurosurgeon's Quest to Discover the Mysteries of the Brain and the Secrets of the Heart By Jim Doty Neurosurgeon Jim Doty is the director of the Center for Compassion and Altruism Research and Education (CCARE) at Stanford University.
