Alzheimer’s disease and age-related dementia are associated with progressive impairment of cognitive function frequently severe enough to interfere with an individual’s activities of daily living. With over 50 million Americans age 65 and greater these diseases are regarded as the most significant public health challenges. Presently approximately 6 million Americans are living with Alzheimer’s disease and this projected to increase to 14 million in the next 30 years.
Presently there are no effective drug therapies to prevent or significantly ameliorate ADRD. I am convinced, however, that due to the brain’s neuroplasticity, the ability to change and adapt, that cognitive function CAN be improved and enhanced at almost any age. In the search for modifiable risk factors there are several that hold promise, particularly if started in the 50’s or even 60’s.
- Avoiding environmental toxins
- Controlling stress
These are all well documented in my book, Square One-A Simple Guide to a Balanced Life.
Scientific evidence supports the Mediterranean diet pattern heavy on flavonoid rich fruits and vegetables and plant based. This has the potential to reduce the risk of cognitive decline and Alzheimer’s disease related dementia (ADRD). The flavonoids most commonly recommended include anthocyanin-rich berries and red wine, flavanone-rich citrus fruits and juices, flavan-3-ol-rich teas particularly green tea and dark chocolate, flavone-rich parsley and celery and flavanol-rich onions and apples and isoflavone-rich soy products. Various clinical studies have indicated positive findings in the areas of memory, executive function and attention.
It is now well recognized that exercise is the most effective way to increase BDNF (brain derived neurotrophic factor). This growth factor is like Miracle Gro® of the brain in that it increases the formation of new brain cells, new synaptic connections and enhances neuroplasticity. In addition, myokines, one of several hundred small proteins (cytokines) that are produced and released by muscle cells in response to muscular contraction are both anti-inflammatory and enhance our immune system. These molecules also help to prevent sarcopenia, a common cause of muscle atrophy in aging. Aerobic and resistance exercises also “reset” our neurotransmitters like serotonin, acetylcholine, anandamide, norepinephrine and dopamine which contribute to mood stabilization. Physical aerobic activity is also one of the best anti-depressants when performed regularly and some studies show it is better than antidepressants drugs for mild to moderate depression.
It is well recognized that excessive use of alcohol, smoking, various types of mood-altering drugs, air pollution, contaminated water all can have deleterious effects on brain function. Alcohol in moderation may have some beneficial effects but in excess contributes to ienumerable medical and health issues.
Much is written about the deleterious effect of stress. We know it destroys brain cells when chronic and unmitigated, particularly in the area of the brain controlling memory, the hippocampus. Many popular methods are promoted for stress control including meditation, prayer, yoga, tai chi. In addition, fostering strong relationships is essential with family and friends and provides support and resilience when life’s “storms” strike.
Practice gratitude, show appreciation, forgive transgressions, be compassionate and regularly nurture a positive view and attitude.
Finally, adequate rest and sleep are essential. During sleep autophagy occurs which is the body’s innate process for removing waste products from within cells and encoding and organizing memories.
