It's a no-brainer: no pills, no side effects from meds. Just exercise!
Over five years of research, older adults who did not engage in moderate to high levels of exercise experienced greater declines in cognitive processing speed and memory function. This decline was the same as would have been expected with 10 years of aging instead of the 5 years that actually past in the study.
PositiveTip: Stay active as you age. It is essential for brain health!
Cumulative lifetime use of marijuana hurts cognitive function in middle age.
Today many portray marijuana use as harmless. With more and more states legalizing its use, many believe it has no long-term effects on memory or other areas of cognitive function. Researchers followed over 3000 individuals for 25 years. Current marijuana use was associated with worse verbal memory and processing speed along with lower executive function in middle age.
PositiveTip: It may seem relatively harmless, but the use of marijuana negatively impacts cognitive function years later.
A lifetime of physical activity is what really counts.
A group of 1635 seniors were randomly assigned to receive either a structured, moderate-intensity program of physical activity (walking, flexibility, resistance training) or health education workshops and upper-body stretching for two years. Researchers did not find any significant difference between the groups in either cognitive improvement or less mild cognitive impairment. This two-year study should not be understood to suggest a life-long program of good physical activity is without considerable value.
PositiveTip: Regular physical activity throughout life is important for maintaining mental and physical health.
