Proteins like Reelin, which helps assemble the brain and maintain memory, and p62, which clears toxic proteins, show promise in protecting against dementia, while boosting proteins like Sox9 can help brain cells clear amyloid plaques, with research also pointing to LDL receptor (linked to heart health) and DHA (an omega-3) metabolites as potentially neuroprotective, highlighting various natural processes and targets for future treatments.
A protein called Reelin may help protect brains against aging and Alzheimer's : Shots - Health News Early in life, the protein Reelin helps assemble the brain. Later on, it appears to protect the organ from Alzheimer's and other threats to memory and thinking.
Foods containing high levels of antioxidants such as berries and kiwis are effective in helping to prevent and reduce inflammation. Colorful vegetables, dark chocolate and turmeric can also go a long way in protecting the brain from early onset dementia.
A small benefit for the brain
The study, published Wednesday in the journal Neurology, found people who ate 50 grams (about 2 ounces) or more of high-fat cheese daily had a 13% lower risk of dementia than those eating less than 15 grams (0.5 ounce).
In Alzheimer's disease, the abnormal proteins are called beta-amyloid and tau. These two proteins combine with themselves into large conglomerates that are the plaques and tangles of this disease.
Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells. One of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells.
Studies have shown a correlation between diets high in excess saturated fats, simple sugars, and ultra-processed foods and an increased risk of developing dementia. Examples of foods to avoid include processed meats, packaged snacks, sugary beverages and desserts, and excess alcohol.
Vitamin D supplements are linked to a significant reduction in dementia risk, with a major study showing users had a 40% lower incidence of developing dementia compared to non-users, particularly benefiting older adults, with even greater effects seen in women and those without existing cognitive issues. This reduction highlights Vitamin D's role in brain health, possibly by clearing amyloid plaques associated with Alzheimer's.
The cause of roughly 70% of all dementia cases is Alzheimer's disease, a progressive brain disorder characterized by the buildup of amyloid plaques and tau tangles, leading to memory loss and impaired thinking that interferes with daily life, making it the most common form of dementia.
Blueberries, the well-known 'super fruit,' could help fight Alzheimer's - YouTube.
Three meta-analyses, each including numerous observational studies, have reported that greater green tea consumption is associated with a 33-47% lower risk of cognitive impairment and a 25-29% lower risk of dementia [1; 2; 3].
You Miss Out on Sleep
You do a few things you know you shouldn't -- we all do. But some of those bad habits can take a toll on your brain. For example, lack of sleep may be a cause of dementia, including Alzheimer's disease. It's best to have regular sleeping hours.
A study published in the journal Nutrients found that people who ate eggs regularly had better cognitive (thinking and memory) performance than non-egg eaters. Similarly, a study in The Journal of Nutrition suggests older adults who ate eggs frequently were less likely to develop Alzheimer's disease.
Smoking, low physical activity, and a poor diet are all lifestyle and environmental influences that have been linked to rapid dementia decline. Physical activity promotes cardiovascular health, which in turn improves brain function. Those who lead a sedentary lifestyle may experience faster cognitive decline.
There are no foods that directly cause amyloid plaques. Amyloid proteins are made by the body — they're very different from the protein found in food. Food doesn't cause amyloidosis. Eating protein from a variety of healthy sources, such as poultry, fish, and beans, is essential for good health.
Our results confirm that vitamin D deficiency is associated with a substantially increased risk of all-cause dementia and Alzheimer disease.
Abstract. Finland has the highest death rate from dementia in the world and its environmental features can be instructive in understanding hidden causes of dementia.
Although Alzheimer's disease is still the most common type of dementia in people under 65, a higher percentage of people in this age group may develop frontotemporal dementia than older people. Most cases are diagnosed in people aged 45-65.
Donanemab, like lecanemab, is a type of drug called a monoclonal antibody. Antibodies form part of our immune system and bind to harmful proteins to destroy them. Donanemab contains antibodies that bind to a protein called amyloid, which builds up in the brain in the early stages of Alzheimer's disease.
The vitamins that support overall brain wellness include B vitamins, particularly B6, B12, and folate, as well as vitamin D and vitamin E. These nutrients contribute to cognitive function, memory, and overall brain health.
Doing regular physical activity is one of the best ways to reduce your risk of dementia. It's good for your heart, circulation, weight and mental wellbeing. There are two main types of physical activity – aerobic activity and strength-building activity. Each type will keep you fit in different ways.
The "2-finger test" for dementia involves an examiner showing a hand gesture (like interlocking index and middle fingers) and asking the patient to copy it, testing motor skills, visual memory, and coordination, as difficulties can signal early cognitive decline, but it's a screening tool, not a definitive diagnosis, prompting further medical evaluation. Other related tests include finger-tapping and finger-to-nose, looking for hesitation or misjudgment in movement.
The 10 warning signs of dementia include memory loss, difficulty with familiar tasks, confusion about time/place, trouble with language, poor judgment, misplacing things, personality changes, loss of initiative, and problems with visual/spatial skills, requiring professional assessment to distinguish from normal aging.
