I’m a brain health expert - here’s why shingles vaccines may fight dementia

1 week ago | nzherald.co.nz | Richard Sima

“The shingles vaccines … seem to be one of those drugs,” said Taquet, who was not involved in the study. In medical research, randomised controlled trials are the gold standard for measuring the effectiveness of a treatment or intervention by randomly dividing similar participants into treatment and control groups. However, this controlled comparison is often not possible in the real world.

Want to reduce your risk of dementia? Consider getting the shingles vaccine. A new study provides the strongest evidence yet that a shingles vaccine reduces the risk of dementia. Researchers tracked more than 280,000 adults in Wales and found that the shingles vaccine cut the risk of developing dementia by 20% over a seven-year period. The new findings, published in Nature, could have implications for managing the large and growing burden of dementia.

By Richard SimaThe Washington PostFor a healthy brain as we age, we need healthy blood pressure. However, nearly half of American adults have hypertension, which is one of the most common — and preventable — risk factors for developing dementia decades later, research shows.

In March 2020, Hannah Davis fell ill, and everything changed. Her respiratory symptoms were mild, but the neurological and cognitive fallout was frightening. “I could tell very early on that something was wrong with my brain,” she said after getting sick with COVID-19. And Davis had quantitative proof — her score for processing speed on a cognitive test dropped from the 96th percentile right before the pandemic to the 14th percentile after her coronavirus infection.

Respire fundo. Agora expire e observe como se sente. Se você se sentir um pouco mais calmo, acabou de experimentar o poder da respiração consciente e intencional. Pesquisas mostram que realizar algumas técnicas e desacelerar a respiração podem aliviar o estresse e melhorar o humor ao aproveitar a influência (muitas vezes sutil, mas profunda) que a respiração exerce sobre o que pensamos, sentimos e como nos comportamos.
