Daylight saving time arrives this weekend, which means it's once again time to move the clocks ahead an hour. The change, which takes effect at 2 a.m. this Sunday, will cost millions of Americans an hour of sleep and leave many of us feeling extra groggy. Health experts say there can also be some more serious consequences. "The main impact of daylight savings time is the loss of sleep and the need to 'shift' the timing of sleep after the clocks change. This has two consequences," Dr. M. Safwan Badr, a pulmonologist atDMC's Detroit Receiving Hospital, told CBS News. "First, missing an hour of sleep makes people sleepy, especially if their sleep time is already short the week before. Furthermore, It takes most people several nights to shift their circadian rhythms and get their sleep back on track."The disruption in sleep patterns can have a number of effects on your health.Mood, memory, and concentrationPerhaps the most common and noticeable way the loss of sleep affects people is … [Read more...] about Daylight saving time: Health risks and how to adjust to losing an hour of sleep
Increasing blood flow to the brain
Jan 24, 8:09 AM EST Newsletter Signup BusinessTechnologyWorldNationalMedia & CultureOpinionSportsLuxury National By Thomas E Cope 01/07/18 AT 8:00 AM Alzheimer’s disease is a devastating brain illness that affects an estimated 47m people worldwide. It is the most common cause of dementia in the Western world. Despite this, there are currently no treatments that are effective in curing Alzheimer’s disease or preventing its relentless progression.Alzheimer’s disease is caused by the build-up of two abnormal proteins, beta-amyloid and tau. Tau is particularly important because it causes neurons and their connections to die, preventing brain regions from communicating with each other normally. In the majority of cases, tau pathology first appears in the memory centres of the brain, known as the entorhinal cortex and hippocampal formation. This has been shown to occur many years before patients have any symptoms of disease.Over time, tau begins to … [Read more...] about How Alzheimer’s Disease Spreads Throughout The Brain, New Study Says
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?
Feelings of sadness or anxiety might be linked to increased "chitchat" between two areas of the brain, a new study suggests. In the study, published today (Nov. 8) in the journal Cell, a group of researchers listened in on electrical conversations in the brain — in other words, the signals that brain regions send to one another. When a person is feeling down, they found, the communication increased between brain cells in two specific regions of the brain involved in memory and emotion. It's unclear whether this increased brain communication is a cause or an effect of a bad mood, the researchers noted. However, the findings allowed them to home in on the part of the brain where the action is. [5 Ways Your Emotions Influence Your World (and Vice Versa)] What is clear, however, is that anxiety, depression and mood have physical manifestations in the brain. "For many patients, it is very important to know that when they are feeling depressed, it is due to something measurable and … [Read more...] about What Does Sadness Look Like in the Brain?
A rapidly progressing “polio-like” illness is leaving children in numerous states paralyzed – and experts aren’t sure what’s causing the kids to fall ill.The rare disease, called Acute Flaccid Myelitis (AFM), causes an “inflammation of spinal cord” that resembles cases of polio from the 20th century, Johns Hopkins associate professor of neurology and pathology Dr. Carlos A. Pardo told the Daily News.Cases of AFM have recently been reported in at least five states: Minnesota, Washington, Illinois, Colorado and Pennsylvania.The exact cause of AFM is unknown — it may be a new virus that some children do not have enough immunity to combat and therefore have a bad reaction where the nervous system fails, or the virus attacks the spinal cord directly.“The CDC found evidence of enterovirus D68 in respiratory samples in approximately 20% of patients affected, and other viruses in another 20%, though in the majority of cases a trigger was … [Read more...] about Everything you need to know about the ‘polio-like’ illness popping up around the U.S.
