A higher resting heart rate can be an independent risk factor for dementia, according to new research from the Karolinska Institute. The research was published in the journal 'Alzheimer's & Dementia: The Journal of the Alzheimer's Association.'
According to Alzheimer's Disease International, the number of individuals living with dementia is expected to rise to 139 million by 2050, up from 55 million in 2020. There is currently no cure for dementia, but emerging research suggests that living a balanced lifestyle and keeping good cardiovascular health can help prevent the onset of dementia and alleviate symptoms.
The researchers wanted to see if resting heart rate could be connected to dementia and cognitive impairment in 2,147 people in Stockholm who were 60 years old or older and didn't have any other known risk factors like cardiovascular disease.
Individuals with a resting heart rate of 80 beats per minute or above had a 55 percent higher risk of dementia than those with a heart rate of 60-69 beats per minute, according to the study, which followed the participants for up to 12 years.
