People who report an elevated number of depression symptoms may be more likely to have a stroke years later than people with no depression symptoms or a low number of depression symptoms, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.
For people with multiple sclerosis (MS), drinking around 290 calories per day of soda or other sugar-sweetened beverages, or the equivalent of about two cans of non-diet soda, may be tied to more severe symptoms and a higher level of disability compared to people with MS who seldom consume sugar-sweetened beverages, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in Philadelphia, May 4 to 10, 2019. People who seldom drank sugar-sweetened beverages consumed an average of seven calories in sugar-sweetened beverages per day, or the equivalent of one-and-a-half cans of non-diet soda per month. Soda and other sweet beverages were the only type of food that was related to MS symptoms in the study.
It may seem counterintuitive, but having some extra body fat may be linked to an increased chance of surviving a stroke, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.
People who are witnessed by a bed partner to have stopped breathing during sleep may have higher accumulations of an Alzheimer’s disease biomarker called tau in an area of the brain that helps with memory, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.
Medical marijuana may bring relief to older people who have symptoms like pain, sleep disorders or anxiety due to chronic conditions including amyotrophic lateral sclerosis, Parkinson’s disease, neuropathy, spinal cord damage and multiple sclerosis, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in Philadelphia, May 4 to 10, 2019. The study not only found medical marijuana may be safe and effective, it also found that one-third of participants reduced their use of opioids. However, the study was retrospective and relied on participants reporting whether they experienced symptom relief, so it is possible that the placebo effect may have played a role. Additional randomized, placebo-controlled studies are needed.
Playing professional soccer may be linked to an increased risk of developing amyotrophic lateral sclerosis (ALS), according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in Philadelphia, May 4 to 10, 2019. The study also found that soccer players may develop the disease 21 years earlier than people in the general population do.
While drugs that lower blood pressure and cholesterol have been shown to be beneficial for heart health, a new study has found that two such drugs may not provide a similar benefit to the brain. The study, published in the February 27, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology, found that when older people took candesartan plus hydrochlorothiazide to lower blood pressure or rosuvastatin to lower cholesterol, or a combination of the two, the drugs did not slow decline in thinking and memory.
Keeping physically and mentally active in middle age may be tied to a lower risk of developing dementia decades later, according to a study published in the February 20, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.

But results have been mixed, and a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the February 6, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.

For people in their 20s and 30s, having blood pressure above normal but below the level considered to be high blood pressure, may be linked to loss of brain volume, according to a study published in the January 23, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Older adults who move more, either with daily exercise or even simple routine physical activity like housework, may preserve more of their memory and thinking skills, even if they have brain lesions or biomarkers linked to dementia, according to a study published in the January 16, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Carrying extra body fat, especially around the middle, may be linked to brain shrinkage, according to a study published in the January 9, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Taking antidepressants for depression, having post-traumatic stress disorder or anxiety diagnosed by a doctor are risk factors for a disruptive and sometimes violent sleep disorder called rapid eye movement (REM) sleep behavior disorder, according to a study published in the December 26, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study also found men are more likely to have the disorder.

After six months of exercise, study participants’ scores on thinking tests improved by the equivalent of reversing nearly nine years of aging.

The study is published in the November 9, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
In the past, researchers believed that Parkinson’s disease did not affect life expectancy. But recent studies showed a somewhat shorter life span. Now a new study suggests that when the disease does not affect thinking skills early on, life span is not affected. The study is published in the October 31, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.

The eyes may be a window to the brain for people with early Parkinson’s disease. People with the disease gradually lose brain cells that produce dopamine, a substance that helps control movement. Now a new study has found that the thinning of the retina, the lining of nerve cells in the back of the eye, is linked to the loss of such brain cells. The study is published in the August 15, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
