Revised guidelines improve survival rates for traumatic brain injury patients

Revised guidelines improve survival rates for traumatic brain injury patients

Health
May 8 (UPI) -- People suffering severe traumatic brain injury may have a better chance of surviving when emergency medical responders follow certain guidelines before getting to the hospital, new findings show. When EMS workers focused on preventing low oxygen, low blood pressure and hyperventilation, survival rates for severe TBI patients doubled, according to research published Wednesday in JAMA Surgery. Survival rates tripled for people with TBI when EMS workers inserted breathing tubes, the researchers say. "This demonstrates the significance of conducting studies in real-world settings and brings a strong evidence base to the guidelines," Patrick Bellgowan, program director at National Institute of Neurological Disorders and Stroke, said in a news release. "It suggests we can systema...
New brain cells made throughout life

New brain cells made throughout life

Health
People keep making new brain cells throughout their lives (well at least until the age of 97), according to a study on human brains. The idea has been fiercely debated, and it used to be thought we were born with all the brain cells we will ever have. The researchers at the University of Madrid also showed that the number of new brain cells tailed off with age. And it falls dramatically in the early stages of Alzheimer's disease - giving new ideas for treating the dementia. Most of our neurons - brain cells that send electrical signals - are indeed in place by the time we are born. Studies on other mammals have found new brains cells forming later in life, but the extent of "neurogenesis" in the human brain is still a source of debate. The study, publish...
Lower blood pressure boosts brain function in elderly, study says

Lower blood pressure boosts brain function in elderly, study says

Health
March 18 (UPI) -- Having lower blood pressure can boost brain function in older adults, a new study says. When elderly people took medicine to keep their systolic blood pressure around 130 mm for three years, they were less likely to suffer a heart attack, stroke or other cardiovascular event, according to research presented at the American College of Cardiology's 68th Annual Scientific Session. "I think it's an important clinical finding and a very hopeful one for elderly people who have vascular disease of the brain and hypertension," said William B. White, a researcher at the University of Connecticut School of Medicine's Calhoun Cardiology Center and study principal investigators. "With the intensive 24-hour blood pressure treatment we reduced the accrual of this brain damage by 40 p...
Some with schizophrenia have similar brain function to healthy people

Some with schizophrenia have similar brain function to healthy people

Health
Jan. 4 (UPI) -- The brains of healthy people may be similar to those of people with schizophrenia, a study says. A study of 179 people -- 109 with schizophrenia and 70 without it -- published Friday in the American Journal of Psychiatry shows the brain similaries in MRI scans and facial recognition tests. The findings, which reflect participants with and without the condition, broke participants down into three distinct facial types -- typical, over-activated and de-activated profiles -- helping the researchers determine similarities and differences between each of them. "We think those with over-activated networks may be 'inefficient' in terms of brain activity -- they probably struggled more and needed to work harder to do the same task compared to the other groups," says Dr. Hawco. "Th...
