A team of scientists, led by researchers at University of California San Diego School of Medicine, report that a class of drugs used for a broad array of conditions, from allergies and colds to hypertension and urinary incontinence, may be associated with an increased risk of cognitive decline, particularly in older adults at greater risk for Alzheimer’s disease (AD).
O primeiro estudo da referência concluiu que a desidratação teve efeitos negativos no vigor, autoestima, memória de curto prazo e atenção. A reidratação, porém,atenuou esses efeitos. O segundo é o maior e mais abrangente estudo controlado a examinar como o estado de hidratação interfere no desempenho cognitivo. Inédito ao avaliar a questão em uma população com idade mais avançada, sendo os resultados negativos significativos para as mulheres. A atenção sustentada, velocidade de processamento, memória de trabalho e motricidade foram examinadas. Os cientistas responsáveis pela pesquisa evidenciaram também que a hiperidratação, particularmente se resultar em hiponatremia, pode ser tão preocupante para a função cognitiva como a desidratação. 🧠💦🗯 Esse e outros temaa relcaionados serão abordados no módulo Saúde & Alta Performance Cerebral da @mybrainuniversity
Yale researchers have found a neural home of the feeling of stress people experience, an insight that may help people deal with the debilitating sense of fear and anxiety that stress can evoke, Yale researchers report May 27 in the journal Nature Communications.
Brain scans of people exposed to highly stressful and troubling images — such as a snarling dog, mutilated faces or filthy toilets — reveal a network of neural connections emanating throughout the brain from the hippocampus, an area of the brain that helps regulate motivation, emotion and memory.
The brain networks that support the physiological response to stress have been well studied in animals. Activation of brain areas such as the hypothalamus triggers production of steroid hormones called glucocorticoids in the face of stress and threats. But the source of the subjective experience of stress experienced by people during the COVID-19 pandemic, for instance, has been more difficult to pinpoint.
Scientists have collected plenty of evidence linking exercise to brain health, with some research suggesting fitness may even improve memory. But what happens during exercise to trigger these benefits? New UT Southwestern research that mapped brain changes after one year of aerobic workouts has uncovered a potentially critical process: Exercise boosts blood flow into two key regions of the brain associated with memory. Notably, the study showed this blood flow can help even older people with memory issues improve cognition, a finding that scientists say could guide future Alzheimer’s disease research.
Long after danger has passed, the nervous system may still remember trauma. . .
. . . which can leave clients feeling hypervigilant, dissociative, or numb for years to come.
So to help clients heal, we need to understand what makes traumatic memory so overwhelming, and the most effective ways to work with it.
Not only that, we need strategies so clients can “unlearn” the nervous system’s response to trauma.
That’s why we created a course that focuses solely on how to work with traumatic memories that get embedded in the nervous system.
Three of the world’s top experts will share how they treat clients who have experienced trauma. This new program brings together their sharpest strategies for working with traumatic memory.
In recent years, nootropics, also called smart drugs, have gained popularity among people looking to improve their mental performance.
Acetylcholine is a neurotransmitter, or brain chemical, that plays a role in many key aspects of brain function, such as memory, thinking, and learning.
While acetylcholine supplements don’t exist, supplements that may indirectly raise acetylcholine levels have become popular among people interested in nootropics as a way to enhance mental performance.
This article explores the benefits and side effects of acetylcholine supplements, and outlines the best types.
