To help keep dementia away, aim for at least 7,000 to 9,800 steps a day, as studies show this range significantly lowers dementia risk, with benefits starting even at 3,000-4,000 steps, and faster walking boosting protection. While 10,000 steps is a popular goal, the key is consistent movement and increasing intensity, with benefits plateauing around 9,800 steps for dementia prevention.
When it comes to preventing Alzheimer's disease, every step counts. For older people whose brains have begun to show molecular signs of the disease, but who have yet to display any cognitive symptoms, taking as few as 3,000 to 5,000 steps per day can help to stave off mental decline, a study finds1.
Seroquel is the brand name for quetiapine, an atypical antipsychotic that is used off-label to treat severe behavioral signs of dementia. It can help with bad symptoms, including agitation, aggressiveness, and hallucinations, that other drugs don't help with.
Eat a balanced diet — such as the Mediterranean diet — that's rich in vegetables, fruits and lean protein, particularly protein sources containing omega-3 fatty acids. Be physically and socially active, including engaging in aerobic exercise. Maintain a healthy weight. Take care of your mental health.
Reduce your risk of dementia
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.
A large study found that older adults who took vitamin D had a 40% lower chance of developing dementia than those who didn't. You can get vitamin D from food like fish, eggs, and vitamin D-fortified milk.
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.
Get enough sleep each night—7 to 8 hours for most adults. Memories won't be strengthened with 4 hours or less of nighttime sleep. Naps might help or hinder. A 90-minute nap can strengthen memories, but naps late in the day may make it harder to get to sleep at night.
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.
Meaningful activities are a great way to bring joy, connection, and comfort to a loved one with dementia. Simple things like enjoying a favorite song, moving a little each day, or engaging in familiar routines can make a big difference in their well-being.
When someone gets the diagnosis of dementia, a cure is only very rarely possible (see p2 About Reversible Dementias). In the current issue of Neurology, Sacks and Shulman1 report one of these rare cases of a reversal of dementia involving a patient on steroid medication.
While there's no single "magic bullet," fitness experts often point to the squat (or sit-to-stand) as the #1 exercise for seniors because it builds essential leg and core strength for daily living, preventing falls and maintaining independence, alongside vital aerobic activities like brisk walking for heart health. A balanced routine combines these with strength training (weights, bands), balance work (yoga, Tai Chi), and flexibility.
The 3x3 walking method, or Japanese Interval Walking Training (IWT), is a workout that alternates between 3 minutes of brisk walking and 3 minutes of slow walking, repeated for about 30 minutes total (around 5 cycles). This low-impact routine improves cardiovascular health, strength, and balance by elevating your heart rate and then allowing recovery, making it effective for weight management, blood pressure, and blood sugar control, and it's a time-efficient way to boost fitness.
The researchers found dementia risk decreased with higher amounts of physical activity. Dementia risks were 60% lower in participants in the 35 to 69.9 minutes of physical activity/week category; 63% lower in the 70 to 139.9 minutes/week category; and 69% lower in the 140 and over minutes/week category.
They also found that breakfast skippers were more likely to experience cognitive decline and signs of neurodegeneration during the study period. Ultimately, the researchers concluded that “breakfast skipping was linked to an increased risk of long-term cognitive decline and neurodegeneration among older adults.”
Cognitive Health and Older Adults
By the age of 75-80, 40% of people have a diminished ability to absorb food-bound B12, says Mason. This deficiency leads to a decline in nerve health, particularly in the spine and brain, which can contribute to the risk of developing dementia in older adults.
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.
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.
The increasing number of cases is directly tied to the aging of the U.S. population. Beyond aging, a high risk of dementia is linked to genetic factors, as well as high rates of hypertension and diabetes, obesity, unhealthy diets, lack of exercise, and poor mental health.
Mild cognitive impairment (MCI) is often regarded as an intermediate state on a one-way path from normal cognition to dementia. However, several longitudinal epidemiologic studies have found that transition from an MCI diagnosis back to normal cognition is fairly common.
