There's no single miracle cure for dementia, but new disease-modifying drugs like lecanemab (Leqembi) and donanemab (Kisunla) offer hope by targeting amyloid plaques, slowing cognitive decline in early Alzheimer's, but they aren't cures and have side effects like brain swelling. Older treatments focus on symptom management, while lifestyle changes and ongoing research aim for better prevention and management, with a strong focus on early diagnosis and addressing underlying causes.

What is the new drug that reverses dementia?

Lecanemab targets a protein called amyloid that builds up in the brains of people with Alzheimer's disease. It is an immunotherapy, which means it uses the immune system of the brain to remove the amyloid protein.

What vitamin cuts dementia risk by 40%?

Vitamin D supplementation is linked to a significant reduction in dementia risk, with one large study showing a 40% lower incidence in older adults taking supplements compared to those who didn't, highlighting benefits especially for women and those without the APOE-e4 gene, though more clinical trials are needed to confirm causation. Another study found diets high in riboflavin (vitamin B2) were associated with nearly 50% lower disabling dementia risk.
 

What is the number one food that fights dementia?

While there's no single "magic" food, fatty fish (like salmon) rich in omega-3s and leafy greens are consistently highlighted as top contenders for fighting dementia, with studies showing fish as a key factor in reducing cognitive decline risk, followed by vegetables. Combining these with other antioxidant-rich foods like berries, nuts, seeds, and whole grains, as seen in Mediterranean or MIND diets, offers the best protection.

Other causes include vascular dementia (due to poor blood flow) and Lewy body dementia (from protein clumps), often occurring in combination with Alzheimer's.
 

What is the downside of Ozempic?

The cons of Ozempic (semaglutide) include common gastrointestinal side effects (nausea, vomiting, diarrhea, bloating, constipation), potential for serious issues like pancreatitis, kidney problems (from dehydration), vision changes (diabetic retinopathy), and gallbladder issues, plus the risk of significant muscle loss, high cost, and the need for indefinite use to maintain results. It also carries a boxed warning for thyroid tumors (from animal studies) and requires discontinuation before surgery.

Can a person with dementia improve?

While most dementias are progressive and currently incurable, symptoms can often be managed to slow decline and improve quality of life, and in rare cases (like vitamin deficiency), reversal might be possible. Treatments include medications (like cholinesterase inhibitors, memantine, or newer anti-amyloid drugs for early Alzheimer's), lifestyle changes (exercise, healthy diet, social engagement), and managing underlying health conditions. The goal is to maintain independence and function for as long as possible.

A peanut butter and jelly (PB&J) sandwich adds about 33 minutes to your healthy life expectancy per serving, according to a University of Michigan study using its Health Nutritional Index (HNI), with benefits coming from healthy fats, protein, and antioxidants in the ingredients.

Dementia acceleration is linked to managing other health issues like diabetes, heart disease, high blood pressure, obesity, and stroke, along with lifestyle factors such as poor diet (processed foods, sugar, salt), alcohol, smoking, social isolation, lack of sleep, depression, and air pollution, which harm brain health and blood vessels, speeding up decline. Serious infections, falls, and changes in routine can also worsen symptoms quickly. 

What are Ozempic hands?

"Ozempic hands" is a popular term for the visible changes in hands due to significant weight loss from drugs like Ozempic, making them look bonier, thinner, or more aged with prominent veins and tendons because of lost fat and thinner skin. It's not a formal diagnosis but describes the loss of fat volume, causing underlying structures to stand out, similar to "Ozempic face" or "Ozempic feet," resulting from rapid fat loss where skin doesn't keep up.
 

Who cannot take Ozempic?

You should not take Ozempic if you have a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), are pregnant, breastfeeding, or have a history of pancreatitis, severe kidney problems, or a serious allergic reaction to semaglutide. It's also generally not for people with Type 1 diabetes, and caution is advised with diabetic retinopathy, gallbladder issues, or alcohol use. 

What are Ozempic feet?

"Ozempic feet" is a non-medical term for changes in the feet, like sagging skin, visible veins/tendons, and pain, that happen due to the rapid fat loss from using GLP-1 drugs (like Ozempic, Wegovy) for weight loss, resulting in loss of natural fat padding and looser skin, similar to "Ozempic face". It's not the drug itself but the significant weight loss that causes fat loss in the feet, leading to discomfort, burning, or a "walking on bone" feeling, though it can often be managed with proper foot care and supportive footwear.
