In the time that it takes to say this sentence – three seconds – someone in the world will develop dementia, a group of symptoms impacting memory, thinking, mood, behaviour and the ability to complete everyday tasks. Alzheimer’s is the most common form of dementia.With people living longer, even into their 90s and beyond, dementia is becoming the biggest and most consequential global health threat of our time. But, according to a landmark study in The Lancet medical journal, there are 12 modifiable risk factors that can reduce your chances of getting dementia at any age – by up to 40%. In this episode of Your Complex Brain, we discuss which of those risk factors are most impactful to lower – or even reverse – your risk of dementia, with a focus on the latest science looking at the benefits of exercise.Featuring: Maria Martinez has been a social worker nearly 25 years.
