Poor sleep in middle age can put you at risk for dementia later in life. That’s according to *** study published Wednesday in the journal Neurology, the authors asked 589 participants around age 40 to self report whether they experienced several characteristics of poor sleep, short sleep duration, bad sleep quality, difficulty initiating and maintaining sleep, early morning awakening in daytime, sleepiness. 15 years later, the authors performed MRI brain scans on those same participants. Subjects who reported 2 to 3 poor sleep characteristics were 1.6 years older in so called brain age. While subjects who reported three or more characteristics were 2.6 years older in brain age. Co-author Clements Caballes told med page today. Advanced brain age is associated with cognitive decline in Alzheimer’s related atrophy patterns. Therefore, poor sleep may be an important target for early interventions aimed at preventing neurocognitive decline if you’re trying to improve your sleep. Clinical psychologist, Doctor Shelby Harris told CBS news cut back on caffeine and alcohol before bed, try relaxation techniques and make sure you get enough exercise

Marijuana hospital visits linked to dementia diagnosis within 5 years, study finds

Sunday is 420 day, when lovers of marijuana get together to celebrate their fondness for weed. Yet research shows that regular users of marijuana are at risk for serious conditions, including strokes, heart attacks, cardiac arrhythmias, heart failure and myocarditis, which is an inflammation of the heart muscle.Video above: Poor sleep in middle age can increase risk of dementiaNow, an increased risk of dementia can be added to the list, according to a large study of more than 6 million people published April 14 in the journal JAMA Neurology.”Someone who has an emergency room visit or hospitalization due to cannabis has a 23% increased risk of dementia within five years compared to someone who was at the hospital for another reason. They have a 72% greater risk compared to the general population,” said study coauthor Dr. Daniel Myran, an assistant professor in the department of family medicine at the University of Ottawa in Canada.”Those numbers have already factored out other reasons for dementia, such as age, sex, mental health or substance use, and whether or not you have chronic conditions such as diabetes or heart disease,” Myran said.Earlier research shows marijuana users are nearly 25% more likely to need emergency care and hospitalization than nonusers.”However, this is not a study that anyone should look at and say, ‘Jury’s in, and cannabis use causes dementia,'” Myran said. “This is a study that brings up a concerning association that fits within a growing body of research.”A red flagThe study is a red flag for health professionals who should be screening for cannabis use disorder, said Dr. Robert Page II, a professor of clinical pharmacy and physical medicine at the University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences in Aurora.”People with cannabis use disorder are unable to stop using even though they encounter health or social problems from use,” said Page, who chaired the medical writing group for the American Heart Association’s 2020 scientific statement on marijuana.”When they stop using it, they either have withdrawal symptoms or have very bad mental health symptoms,” he added. “They might have quite severe depression, or they might have anxiety, all of which can send them to the hospital.”The potency of weed has skyrocketed over the years, which can heighten health risks and is leading to a global rise in marijuana addiction as well as cannabis use disorder, according to a 2022 study.Addiction to marijuana can happen to about 30% of people who use cannabis, according to the US Centers for Disease Control and Prevention.

A red flag

The study is a red flag for health professionals who should be screening for cannabis use disorder, said Dr. Robert Page II, a professor of clinical pharmacy and physical medicine at the University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences in Aurora.

“People with cannabis use disorder are unable to stop using even though they encounter health or social problems from use,” said Page, who chaired the medical writing group for the American Heart Association’s 2020 scientific statement on marijuana.

“When they stop using it, they either have withdrawal symptoms or have very bad mental health symptoms,” he added. “They might have quite severe depression, or they might have anxiety, all of which can send them to the hospital.”

The potency of weed has skyrocketed over the years, which can heighten health risks and is leading to a global rise in marijuana addiction as well as cannabis use disorder, according to a 2022 study.

Addiction to marijuana can happen to about 30% of people who use cannabis, according to the US Centers for Disease Control and Prevention. The disorder also comes with a higher risk of attention, memory and learning problems, the CDC finds.
