Forgetting grandchildren’s names at Thanksgiving. Misplacing keys in an odd location at Christmas. Repeating a story for the second time in an hour on New Year’s Eve. We all wonder, “Is Grandpa just getting old or is something wrong with him?”
These noticeable memory lapses may come with old age, but often lead to the fear that grandpa might be getting Alzheimer’s disease, and prevents us from addressing cognitive impairment in its earliest stages.
What many people don’t realize is that more than half of cognitive impairment is caused by treatable conditions such as heart disease, vitamin deficiencies, diabetes, sleep disorders and depression, and the rest by various neurodegenerative conditions including Alzheimer’s disease. All of these conditions benefit from early detection and treatment, which will stop or greatly slow a progressing of cognitive impairment.
Waiting for symptoms to become obvious is like detecting diabetes when an individual is going blind or having kidney failure, or discovering heart disease when a person has a heart attack — way too late. It’s important that we start to keep track of memory health the same way we keep track of other vital functions.
Prevention and early detection of first signs of cognitive impairment and treating its cause is key to maintaining a healthy brain throughout life. This is extremely important because, like heart disease, diabetes, high cholesterol and breast cancer, we don’t wait until we notice symptoms to begin addressing the underlying cause of disease. We want to be able to detect cognitive impairment and address it at its earliest possible stage.
In addition to an annual memory checkup at a medical facility, there are many things that can be done to prevent or slow cognitive impairment. Lifestyle changes are one of the biggest factors. Healthy diet, physical and mental exercise, and certain supplements can provide a positive impact on cognitive health, while smoking, alcohol and chemical dependency, isolation and a sedentary lifestyle have negative impacts.
Managing existing medical conditions is also important. Risk factors for cognitive impairment include — but are not limited to — diabetes, high blood pressure, high cholesterol, obesity, depression and heart disease, and keeping these conditions under control can provide a positive impact on cognitive health as well. The body is connected to the brain.
