New research reported at the Alzheimer’s Association International Conference (AAIC) 2019 in Los Angeles suggests healthy lifestyle choices — including healthy diet, exercise, and cognitive stimulation — may decrease risk of cognitive decline and dementia. Researchers also found lifestyle modifications may reduce risk even in the face of other risk factors, including genetics and pollution, and provide maximum memory benefit when combined.
Five research studies reported at AAIC 2019 suggest:
- Adopting four or five healthy lifestyle factors reduced risk of Alzheimer’s dementia by 60% compared to adopting none or only one factor.
- Adherence to a healthy lifestyle may counteract genetic risk for Alzheimer’s disease.
- Having a higher cognitive reserve, built through formal education and cognitive stimulation, may benefit the aging brain by reducing risk of dementia among people exposed to high levels of air pollution.
- Confirmation that early adult to mid-life smoking may be associated with cognitive impairment at mid-life, as early as one’s 40s.
- Alcohol use disorder significantly increased risk of dementia in older women.
“While there is no proven cure or treatment for Alzheimer’s, a large body of research now strongly suggests that combining healthy habits promotes good brain health and reduces your risk of cognitive decline,” said Maria C. Carrillo, PhD, Alzheimer’s Association chief science officer. “The research reported today at AAIC gives us attainable, actionable recommendations that can help us all live a healthier life.”
