News-Medical: Alzheimer’s disease: Learning from the past, looking to the future

It has now been 112 years since Dr. Alois Alzheimer first discovered amyloid plaques in the brain of Auguste Deter during an autopsy, and we still don’t have a treatment. Currently, there are several drugs on the market, but these are classed as symptom-modifying drugs, which cannot alter the course of the disease and are […]

Futurity: Brain scans better predict drug relapse

In a new study, brain scan data could correctly predict who would and would not relapse about three-quarters of the time—a significant improvement over past efforts. Predicting who will remain drug-free and who will relapse following treatment for drug addiction has been impossible. Now, psychologists think they’ve found a possible clue. For stimulants like cocaine […]

New Atlas: Wireless “pacemaker for the brain” can detect and prevent seizures autonomously

UC Berkeley researchers have developed a wireless, autonomous, closed-loop neurostimulator that sits outside the head, monitoring electrical activity in the brain and intervening with electrical stimulation to ward off seizures. The device, which the team has called WAND (Wireless, Artifact-free Neuromodulation Device), can record activity at up to 128 points in the brain, and is […]

Health 24: Does air pollution raise autism risk?

Traffic-related air pollution may play a role in development of autism, new research suggests. A Canadian study found that exposure to a common air pollutant during pregnancy was tied to higher odds of a child being diagnosed with autism by age five. That pollutant, nitric oxide, is associated with traffic pollution, the researchers noted. (December […]

New Atlas: Brain protein may be a more direct target for treating anxiety

Evolutionarily speaking, anxiety is an important mental state – but not so much when it gets out of hand, preventing you from leaving the house. Current anti-anxiety medication comes with some negative side effects, but researchers at the Max Planck Institute for Experimental Medicine have now identified a protein in the brain that may be […]

Health 24: How puzzles and games might help your ageing brain

Those Sunday crossword puzzles may not prevent the ageing brain from slowing down – but they might protect it in a different way, a new study suggests. Researchers looked at the “use it or lose it” theory on brain health. The concept holds that mentally engaging activities – from reading to crosswords to board games […]

Medical Xpress: The brain’s support cells show defective development in Huntington’s disease

The neurological disorder Huntington’s disease causes behavioural and motor changes, which among other things are a result of dysfunctional maturation or formation of glial cells, the brain’s support cells, researchers from the University of Copenhagen demonstrate in a new study based on mouse trials. The researchers’ long-term goal is to be able to use the […]

UPI: Study reveals how the brain helps humans focus

New research suggests the brain uses a specific type of neuron in the neocortex to selectively focus attention on specific sensory inputs, while ignoring others. The neurons are one of the reasons humans can hold a conversation in a crowded, noisy room. (December 27, 2018) Read the full article here

Newsmax: Surprising activities that reduce depression risk

Movies, the theater and other cultural events can help you fight the blues as you age. And the more you go, the less depressed you’ll be, new research suggests. The British study showed that older folks can cut their depression risk by 32 percent simply by going to cultural activities every few months. And if […]

Reuters: Pre-deployment insomnia linked to increased risk of PTSD for soldiers

Soldiers who have insomnia before deployment may be more likely to develop post-traumatic stress disorder (PTSD) or experience suicidal thoughts than service members who don’t struggle to sleep before they deploy, a U.S. study suggests. For the study, researchers surveyed U.S. Army soldiers one to two months before they deployed to Afghanistan in 2012, right […]
