Brain Injuries Linked With Dementia Risk

News Picture: Brain Injuries Linked With Dementia Risk

WEDNESDAY, April 11, 2018 (HealthDay News) — A traumatic brain injury (TBI), even a mild one such as a concussion, may raise your risk for dementia, a new study suggests.

Researchers analyzed 36 years of data from 2.8 million people and found that those who sustained TBIs were 24 percent more likely to be diagnosed with Alzheimer’s or other dementias than those with no history of TBI.

But the study did not prove that TBIs cause dementia risk to rise, just that there’s an association.

The study found that 5.3 percent of people with dementia had suffered at least one TBI.

The risk of dementia increased with the number of TBIs and the severity of injury. But even a single, mild TBI (such as a concussion) was associated with a 17 percent higher risk of dementia. The researchers found that 4.3 percent of participants with dementia had at least one mild TBI, compared with 4 percent of those without dementia.

The study was published April 10 in The Lancet Psychiatry journal.

“Individuals with a history of traumatic brain injury, including those with less severe injuries have an increased risk of developing dementia, even decades after the injury,” said study leader Dr. Jesse Fann. He’s a professor of psychiatry and behavioral sciences at the University of Washington’s School of Medicine in Seattle.

“However, it’s important to emphasize that although the relative risk of dementia is increased after traumatic brain injury, the absolute risk increase is low,” Fann noted in a journal news release.

And, “our findings do not suggest that everyone who suffers a traumatic brain injury will go on to develop dementia in later life,” Fann added.

Each year, more than 50 million people worldwide suffer a traumatic brain injury, which occurs when a bump or blow to the head disrupts normal brain function. Leading causes of TBI include falls, traffic crashes and assaults.

Dementia affects 47 million people worldwide, and that number is expected to double in the next 20 years, the researchers said.

“Our analysis raises some very important issues, in particular that efforts to prevent traumatic brain injury, especially in younger people, may be inadequate considering the huge and growing burden of dementia and the prevalence of TBI worldwide,” Fann said.

    With IVF, Are Fresh or Frozen Embryos Better?

    News Picture: With IVF, Are Fresh or Frozen Embryos Better?

    THURSDAY, Jan. 11, 2018 (HealthDay News) — The chances of having a baby after in vitro fertilization (IVF) are similar for most women whether frozen or fresh embryos are used, a new study finds.

    In a group of infertile women with normal ovulation, rates of live birth were nearly 49 percent in those who received frozen embryos. Rates were just over 50 percent for women who received fresh embryos, said researchers at Penn State College of Medicine.

    The study included more than 2,100 women undergoing their first round of IVF. The treatment involves fertilizing a woman’s egg with sperm in a laboratory dish. The resulting embryo is then inserted in the woman’s uterus.

    Previous research by this team found that women with polycystic ovarian syndrome — abnormal ovulation — fared better with frozen embryos.

    But it wasn’t clear whether fresh and frozen embryos offered better chances of success in women who ovulate normally, the study authors explained.

    “This is an important and distinct finding from our previous IVF study, and it suggests that one type of IVF treatment does not fit all, and treatments should be chosen based on specific patient characteristics,” said researcher Richard Legro. He’s a professor of obstetrics and gynecology and public health sciences.

    Researchers also found that women who received frozen embryos had a lower risk of condition called ovarian hyperstimulation syndrome. This sometimes develops in women undergoing fertility treatment. Serious illness or death can occur in severe cases.

    “This study reinforces our previous research by noting that the elective freezing of embryos is safer for all IVF patients… by reducing the risk of ovarian hyperstimulation syndrome,” Legro said in a college news release.

    The findings were published Jan. 10 in the New England Journal of Medicine.

      Protect Your Heart in Frigid Weather

      News Picture: Protect Your Heart in Frigid Weather

      TUESDAY, Jan. 2, 2018 (HealthDay News) — As an Arctic front envelops much of the United States, the American Heart Association wants folks to know that shoveling snow in sub-freezing temperatures can be hard on the heart, especially for those with heart disease.

      Here are some shoveling safety tips from the association:

      • When shoveling, take frequent breaks so you don’t put too much stress on your heart. Assess how you feel during those breaks.
      • Don’t drink alcohol before, during or immediately after shoveling. Alcohol can increase your sensation of warmth, and cause you to underestimate the amount of strain your body is feeling.
      • To prevent hypothermia (a dangerous drop in body temperature), wear layers of warm clothing that trap your body heat. Wear a hat to prevent the loss of body heat through your head.
      • If you have a medical concern or question, or have symptoms of a medical condition such as heart disease or diabetes, you should consult a doctor before shoveling or exercising in cold weather.
      • Know the warning signs of heart attack. But even if you’re not sure it’s a heart attack, have it checked out. Don’t wait to call 9-1-1. Minutes matter in a heart attack, and fast action can be a lifesaver.
      • Learn CPR. It can significantly improve a victim’s chances of survival. If an adult collapses, call 9-1-1 and begin pushing hard and fast in the middle of the victim’s chest until help arrives, the heart association said.
