By discovering the culprit behind decreased blood flow in the brain of people with Alzheimer's, biomedical engineers at Cornell University have made possible promising new therapies for the disease. You know that dizzy feeling you get when, after lying down for an extended period, you stand up a little too quickly? That feeling is caused by a sudden reduction of blood flow to the brain, a reduction of around 30 percent. Now imagine living every minute of every day with that level of decreased blood flow. People with Alzheimer's disease don't have to imagine it. The existence of cerebral blood flow reduction in Alzheimer's patients has been known for decades, but the exact correlation to impaired cognitive function is less understood. "People probably adapt to the decreased blood flow, so that they don't feel dizzy all of the time, but there's clear evidence that it impacts cognitive function," said Chris Schaffer, associate professor of biomedical engineering at Cornell University.

Reduced blood flow to the brain symptoms
You probably don't think of ice cream as a pain-inducing substance, but enjoying those first few spoonfuls of the frozen treat too quickly might bring on a sudden, stabbing pain in the forehead known as "brain freeze." The pain of brain freeze can begin within seconds of being exposed to cold temperatures, and the intensity of the pain peaks very quickly, often within seconds, said Dr. Stephanie Goldberg, a neurologist and headache specialist at Tufts Medical Center in Boston. Why do you get it? Brain freeze, also called an "ice-cream headache," is known in medical terms as a "cold-stimulus headache," Goldberg said. It's a common phenomenon that affects people of all ages, but doctors aren't quite sure why it happens. [Ouch: 10 Odd Causes of Headaches] For this type of headache, the main trigger is any kind of exposure to a significantly cold temperature, Goldberg said. It's not only caused by an internal trigger, like eating frozen treats too quickly; it can also be caused by an … [Read more...] about What Is Brain Freeze?
The Food and Drug Administration approved on Thursday the first drug designed to prevent migraines.A once-monthly, self-injection, Aimovig is the first in a new class of long-acting drugs that is FDA-approved to specifically prevent migraines. It works by blocking the activity of a specific molecule, calcitonin gene-related peptide, that is involved in migraine attacks, the FDA announced in a press release.The drug, expected to be made available to patients within a week, is made by Amgen and Novartis. Without insurance it will cost $575 for once monthly injections or $6,900 per year, Novartis said in a press release.Migraines are more than just headaches. They cause severe throbbing and pulsating pain on one side of the head. They are accompanied by nausea, vomiting and extreme sensitivity to light and sound. Attacks cause significant pain for hours to days and can be so severe that they become debilitating.RELATED: Foods that exacerbate headaches 14 PHOTOS Foods that … [Read more...] about FDA approves first drug to prevent migraines
Update: Yesterday, 17 March, the U.S. Food and Drug Administration approved the first in a new class of drugs designed to prevent migraines. This feature, originally published on 7 January 2016, describes the history of these drugs, the powerful relief they can bring some patients, and the limitations that still exist with them. As long as she can remember, 53-year-old Rosa Sundquist has tallied the number of days per month when her head explodes with pain. The migraines started in childhood and have gotten worse as she’s grown older. Since 2008, they have incapacitated her at least 15 days per month, year-round. Head-splitting pain isn’t the worst of Sundquist’s symptoms. Nausea, vomiting, and an intense sensitivity to light, sound, and smell make it impossible for her to work—she used to be an office manager—or often even to leave her light-proofed home in Dumfries, Virginia. On the rare occasions when she does go out to dinner or a movie with her … [Read more...] about Will antibodies finally put an end to migraines?
caption Weight lifting could help support a healthy mind, according to research from the University of Limerick. source Shutterstock/takoburito New research suggests resistance training could benefit your mind, as well as your physical health. Researchers at the University of Limerick, Ireland conducted a major study into the effects of resistance exercise training (RET) on the symptoms of depression. They concluded it can “significantly reduce symptoms among adults,” but said it’s not a cure and further research is needed. The physical benefits of resistance training, such as burning fat and building lean muscle, are widely recognised – and now new research suggests that it could also support a healthy mind. In a paper published in JAMA Psychiatry, researchers at the University of Limerick, Ireland, conducted a meta-analysis of 33 clinical trials involving 1,877 … [Read more...] about There’s now scientific evidence to suggest that this type of exercise can help relieve symptoms of depression
