People with insomnia more likely to develop dementia later in life, study finds

Struggling to sleep? Scientists say insomnia doesn’t just affect your energy levels the next day - it can also impact your brain health, increasing the risk of dementia.

That’s according to a study that found those with chronic insomnia - trouble sleeping at least three days a week for three months or more - had a 40 per cent higher risk of developing mild cognitive impairment or dementia than those without insomnia.
