This information comes from a recent large UK study. The study showed that while the number of people with memory problems had remained stable, the number of those with cognitive decline had more than doubled between 2009 and 2018.

To come to this conclusion, researchers analyzed information from more than 2.6m adults of 65-99 years old. The analysis showed that 46% of people with memory problems, reported to a doctor, developed dementia within 3 years. On the other hand, people with cognitive decline had even a greater chance (of 52%) to become demented.

When looking at the period of 10 years, for every 1.000 people that were observed in 2009 for 1 year, there was only 1 new person with recorded cognitive decline. By 2018, this number tripled: 3 new people with recorded cognitive decline.

Researchers hope that the results of their study will motivate older people to seek help earlier, if they experience any problems with their brain health.
