We are not close to a single "cure" for dementia, as it's caused by different diseases, but major progress is happening in finding treatments that slow progression, especially for Alzheimer's, with new amyloid-targeting drugs (like lecanemab, donanemab) showing promise and new approaches like early blood tests, stem cells, and lifestyle interventions actively being researched.

What is the breakthrough of dementia in 2025?

In May 2025, the FDA approved the Lumipulse G pTau217/β-Amyloid 1-42 Plasma Ratiotest as a biomarker to diagnose Alzheimer's disease in individuals with cognitive symptoms. “Up until a few years ago, diagnosing Alzheimer's disease involved a lot of guesswork…

How long do people with dementia live?

While the average life expectancy after a dementia diagnosis is often cited as 8 to 10 years, this varies significantly, with some living as few as 3 years and others over 20, depending on the dementia type (Alzheimer's, vascular, Lewy body), age at diagnosis, overall health, and other conditions. For instance, vascular dementia may have a shorter average (around 5 years) due to higher risks of heart attack or stroke, while Frontotemporal dementia averages 6 to 8 years. 

Has anyone recovered from dementia?

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.

What common habit is linked to dementia?

Several common habits significantly increase dementia risk, including physical inactivity, poor diet, excessive alcohol use, smoking, poor sleep, social isolation, hearing loss, and poor oral hygiene, while managing conditions like high blood pressure and diabetes also plays a crucial role in brain health. Adopting healthier habits like regular exercise, staying socially connected, and managing health conditions can help lower your chances of developing dementia. 

How close are we to finding a cure for dementia? Professor Nick Fox

What is the miracle drug for dementia?

Donanemab contains antibodies that bind to a protein called amyloid, which builds up in the brain in the early stages of Alzheimer's disease. This treatment tackles the underlying disease, unlike currently available treatments that can only relieve symptoms.

What causes 70% of dementia?

Alzheimer's disease is the primary cause of roughly 70% of all dementia cases, a progressive brain disorder characterized by protein buildup (plaques and tangles) leading to memory loss and cognitive decline, with other forms like vascular dementia and Lewy body dementia making up the rest, often coexisting with Alzheimer's.

What drink slows down dementia?

Drinking green and black tea can lower the chance of dementia by 16%. These teas are good for the brain because they have flavonoids and L-theanine. 100% orange juice reduces memory loss risk by 36%. It has vitamins like C, thiamin, and B6 that help keep the brain working well.

Why do dementia patients eat ice cream?

People with dementia often experience a dulled ability to taste certain flavors, especially salty or bitter foods. However, the ability to taste sweetness remains relatively intact. As a result, sweet foods become more appealing and even comforting, reinforcing cravings for sugary options.

Ultimately, the researchers concluded that “breakfast skipping was linked to an increased risk of long-term cognitive decline and neurodegeneration among older adults.”

Can statins cut the risk of dementia for all?

Analysis combining 36 studies showed that statins reduced the risk of developing dementia by about 20%. Looking at specific diseases, statins reduced the risk of Alzheimer's disease by about 30% and reduced the risk of vascular dementia by about 7%.

How close are they to curing dementia?

There is currently no cure for dementia. In fact, because dementia is caused by different diseases it is unlikely that there will be a single cure for dementia.
