More people affected by memory diseases in aging society

As the population ages, more people are affected by memory diseases like Alzheimer's. However, research in the field is progressing slowly, and only about half of those affected receive the available treatment.

In an opinion piece in Dagens Nyheter, Lisa Magnusson questions how pleasant the final years of life will truly be for many elderly people. She notes that as lifespans increase, more individuals are affected by memory diseases. Despite this, research in the area is advancing slowly.

The article states that only about half of those suffering from Alzheimer's receive the treatment that is actually available. This raises concerns about how society addresses the rising prevalence of these conditions. Magnusson emphasizes the need for better support and progress in healthcare to ensure a dignified old age.

The piece was published on January 10, 2026, and is part of DN's editorial page, focusing on debate and reflection on societal issues.

A peer-reviewed Neurology study finds a sharp rise in self-reported cognitive difficulties among U.S. adults from 2013 to 2023, with rates nearly doubling in people under 40 and the steepest increases among lower-income and less-educated groups. Authors point to social and economic factors and call for further study.

A recently recognized form of dementia, known as LATE, is reshaping understanding of cognitive decline in the elderly, with rising diagnoses and guidelines for doctors published this year. It is estimated to affect about one-third of people aged 85 or older and 10% of those aged 65 or older, often mistaken for Alzheimer's. Experts emphasize the need for a broader range of treatments for this condition.

Alzheimer's trials are shifting to a multi-target approach inspired by cancer research, even after failures with Novo Nordisk's semaglutide. Only two drugs, Eli Lilly's Kisunla and Eisai and Biogen's Leqembi, are widely approved to slow progression. This evolution treats the brain-wasting disease as a complex system, seeking new ways to halt it amid its global impact.

A 20-year randomized controlled trial has shown that cognitive speed training, combined with booster sessions, reduces the risk of dementia diagnosis by 25 percent among older adults. The study, involving over 2,800 participants aged 65 and older, focused on a computer-based task requiring quick recall of visual details. While results are promising, experts urge caution due to the study's multiple outcome measures.

High meat intake may reduce dementia risk for older people with genetic predisposition to Alzheimer's, per a Karolinska Institutet study. The study tracked over 2,100 individuals aged 60 and older for up to 15 years. Findings apply to carriers of specific apoe gene variants.

European scientists have developed a preliminary method to identify Alzheimer's using a drop of dried blood from a finger, achieving 86% accuracy in detecting amyloid pathology. The study, validated in 337 patients from several countries, is published in Nature Medicine and aims to simplify early diagnosis of this disease affecting over 50 million people worldwide.
