Blueberries are known to boost memory, especially in older adults.
A research team led by Dr. Robert Krikorian at the University of Cincinnati conducted a study involving 16 seniors in their 70s with declining memory. Participants consumed 2 to 2.5 cups of blueberry juice daily for 12 weeks.
The study showed that their memory improved by up to 40% compared to before they began drinking the juice. Additionally, participants scored an average of 33% higher on memory tests than those who drank grape juice.
Dr. Uma Naidoo, a faculty member at Harvard Medical School, also recommends blueberries as a top food for brain health and anti-aging.
Naidoo suggests consuming half to one cup of fresh blueberries daily or enjoying them as juice. She advises choosing firm, vibrant blueberries evenly coated with a light white powder on the surface when selecting fresh blueberries.
Also, Naidoo noted that frozen blueberries without added sugar, juice, or preservatives provide similar health benefits to fresh ones.
Blueberries contribute to memory improvement due to anthocyanins, compounds that enhance communication between brain cells.
Additionally, blueberries are low in calories, rich in antioxidants, and high in vitamins C and E, making them an excellent choice for overall health.
Meanwhile, The Mirror reported that the Alzheimer’s Society in the UK had warned of hand movements as a potential sign of dementia.
Alzheimer’s Society noted that behaviors such as continuously squeezing or rubbing hands often indicate anxiety and are commonly observed in dementia patients. They explained that dementia patients may rub their hands repeatedly, tug at their clothes, or inappropriately touch themselves in public. These behaviors may result from pain, discomfort, the need to use the restroom, increased physical activity, or environmental factors.
They added that some may tug at their clothes while others become anxious, fidget, or pace. In the later stages of dementia, individuals may behave differently from their usual selves.
