| Magnetic stimulation of the brain can improve episodic memory, study finds Posted: 28 Sep 2021 11:18 AM PDT The ability to form episodic memories declines with age, certain dementias, and brain injury. However, a new study shows that low frequency repetitive transcranial magnetic stimulation delivered over the left prefrontal cortex of the brain can improve memory performance by reducing the power of low frequency brain waves as memories form. |
| Happiness in early adulthood may protect against dementia Posted: 28 Sep 2021 09:13 AM PDT While research has shown that poor cardiovascular health can damage blood flow to the brain increasing the risk for dementia, a new study indicates that poor mental health may also take its toll on cognition. |
| Link between diabetes and Alzheimer’s disease bolstered Posted: 28 Sep 2021 09:13 AM PDT Researchers show that chronic hyperglycemia impairs working memory performance and alters fundamental aspects of working memory networks. |
| Targeting a rare secondary cancer in children Posted: 28 Sep 2021 09:13 AM PDT Known as pediatric radiation-induced high-grade gliomas (RIGs), this specific type of brain tumor is caused by cranial radiation therapy for other cancers, most often brain cancers. They account for nearly 4% of all childhood brain tumor deaths, but there have not been many studies on RIGs and how to treat them. |
| Deadly auto crashes more likely during pandemic lockdown Posted: 28 Sep 2021 07:22 AM PDT With fewer people on the road during the early days of the pandemic, more drivers were speeding and driving recklessly, resulting in more crashes being deadly, a new study found. |
| Antidepressants inhibit cancer growth in mice Posted: 28 Sep 2021 07:22 AM PDT Classic antidepressants could help improve modern cancer treatments. They slowed the growth of pancreatic and colon cancers in mice, and when combined with immunotherapy, they even stopped the cancer growth long-term. In some cases the tumors disappeared completely, researchers have found. Their findings will now be tested in human clinical trials. |
| Children who eat more fruit and veggies have better mental health Posted: 28 Sep 2021 04:50 AM PDT New research finds that children who eat more fruit and veg have better mental health. The study is the first to investigate the association between fruit and vegetable intakes, breakfast and lunch choices, and mental wellbeing in UK school children. The research team studied data from almost 9,000 children in 50 schools. They found that the types of breakfast and lunch eaten by both primary and secondary school pupils were significantly associated with wellbeing. |
| Anti-seizure medication improves cognitive function in some Alzheimer’s patients Posted: 27 Sep 2021 02:29 PM PDT An inexpensive anti-seizure medication markedly improves learning and memory and other cognitive functions in Alzheimer's patients who have epileptic activity in their brains, according to a new study. |
| Passage of recreational cannabis laws leads to some rise in use but not for all demographics Posted: 27 Sep 2021 08:04 AM PDT The U.S. is seeing an increased use of cannabis resulting from its legalization for recreational purposes. The findings showed that passage of the laws led to a rise in the odds of past-year and past-month cannabis use among individuals of Hispanic, Other and non-Hispanic whites compared to the period prior to enacting laws for recreational use. However, legalization did not lead to use more frequently, or cannabis use disorder among these groups. |
| Study identifies mechanism by which nicotine withdrawal increases junk food consumption Posted: 23 Sep 2021 08:56 AM PDT New data collected by researchers demonstrate a clear connection between nicotine withdrawal and poor eating habits. Their findings point to the opioid system, the brain functions responsible for addiction and appetite regulation, as a possible cause for smoker preference of energy-dense, high-calorie food during nicotine withdrawal. |
| ADHD and impulsivity: New potential targets to approach the treatment for neuropsychiatric disorders Posted: 23 Sep 2021 07:20 AM PDT A new study describes the existence of a complex built by dopamine and noradrenergic receptors that could be a therapeutic target of potential interest to tackle the attention deficit hyperactivity disorder (ADHD) and impulsivity. |
