The actions one takes today will have a significant impact on quality of life down the road. Older adults may be encouraged to hear that nearly half of dementia cases can be prevented or delayed with lifestyle changes.
According to a recent JAMA Network Global Health report, dementia experts have recently added 3 more preventable risk factors to their previously identified list of 9 preventable risk factors for dementia.
In 2017, The Lancet Commission on Dementia Prevention, Intervention, and Care identified 9 modifiable risk factors that could prevent or delay dementia: having little or no education, hypertension, untreated hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and low social contact. Three additional preventable risk factors added recently include head injuries, excessive alcohol consumption in midlife, and air pollution exposure in later life.
By stopping smoking, staying physically active, limiting alcohol consumption, and wearing hearing aids, middle-aged and older adults can help prevent or delay the onset of dementia in later life. Dementia is not a normal part of aging although nearly 50 million people worldwide have dementia, according to the World Health Organization. Dementia is a leading cause of disability and dependency among older adults and it has a significant physical, psychological, social, and economic impact on people living with dementia as well as their caregivers.
Because the elderly proportion of the population is rapidly growing worldwide, the number of people with dementia is expected to reach 82 million by 2030. By identifying risk factors for dementia, adults can get a head start on making lifestyle changes that can significantly reduce their risk of developing dementia.
