There’s been a major shift in how we think about Alzheimer’s disease, with a new report suggesting it’s starting to be seen as a treatable and preventable condition. The World Alzheimer Report 2026 says that despite slow progress in the past, clinical trials are now on the brink of some big breakthroughs in diagnosis and treatment. This is huge, especially considering the number of people living with dementia is projected to reach 139 million by 2050, making it one of the leading causes of death worldwide.
Researchers are getting closer to understanding the disease and how to prevent it, with some trials showing promise in slowing down its progression. New drugs have hit the market that target and remove the amyloid plaque that builds up in the brains of people with Alzheimer’s, and trials are underway to see if treating people before they show symptoms can prevent cognitive impairment. There’s also been progress in developing blood tests to diagnose the disease, which could make it easier for people to get diagnosed and access treatment.
Lifestyle choices can also play a big role in altering the trajectory of cognitive decline. Studies have shown that things like a healthy diet, regular exercise, and social activity can make a big difference. For example, one study found that participants who followed a lifestyle program that included a healthy diet and regular exercise had 25% more cognitive improvements than those who didn’t. So, what can you do? Exercise regularly, eat a Mediterranean-style diet, and prioritize socializing – and don’t forget to stay connected with your community, as that’s just as important as doing crosswords or brain puzzles.
