Stanford neurologist Sharon Sha, MD, sheds light on the misconceptions surrounding memory and aging. Refuting the common belief that memory loss dramatically worsens with age, Sha explains that the effects of healthy aging on cognitive functions are subtle. She emphasizes, "Although dementia is linked to age, it's not an inevitable part of getting older."
In a discussion on distinguishing between normal aging and dementia, Sha highlights that cognitive impairment indicating dementia involves functional decline, where individuals struggle to carry out daily tasks independently. She notes the importance of recognizing mild cognitive impairment, a decline from one's baseline cognitive function while still maintaining independence.
Regarding the decline in memory function with age, Sha explains, "We don't know exactly what happens biologically." She suggests that memory loss is a part of the general atrophy that occurs in the body as we age. Despite the natural aging process affecting cognitive performance, Sha reassures that accumulated life experience can compensate for any decline in brain function.
When addressing strategies to preserve memory and brain health, Sha emphasizes the significance of lifestyle factors such as exercise, cognitive stimulation, social interaction, a balanced diet, and quality sleep. She advises, "It's never too late -- or too early -- to start taking care of your body and your brain."
In conclusion, Sha underscores the importance of proactive measures in maintaining brain health, stating, "There's no easy pill... It takes work." By adopting a holistic approach that includes physical activity, mental stimulation, social engagement, healthy eating habits, and adequate sleep, individuals can support their cognitive function as they age.
The insights shared by Sha provide valuable guidance on understanding the relationship between aging and memory, offering practical steps to promote brain health throughout life.
