Nina: What are the types of dementia? And what is the probability for developing one of these forms of dementia as you age?
Ram: Memory loss can be a simple age-associated phenomenon or due to a pathological condition. Age is one of the known risks for memory loss or forgetfulness. Age-associated memory loss is not the same as dementia. If a person experiences forgetfulness without having any underlying pathological condition, then the memory loss is solely due to age. Age-associated memory loss is not disabling and does not impact or interfere with daily performance.
Dementia is a pathological term to indicate loss of memory and other mental abilities including thinking and reasoning. The condition can be severe so as to interfere with daily life. Any damage to the memory centers can trigger the onset of dementia. Although many diseases trigger dementia, some forms of dementia may improve greatly when the underlying cause is treated. Dementia can arise due to:
- NeuroDegenerative diseases, including Alzheimer's disease, Parkinson's disease, Huntington's disease (a rare inherited disorder), and multiple sclerosis
- Vascular disorders that results from multiple strokes in the brain
- Traumatic brain injury due to accidents, severe injuries to the brain, hits to the brain
- Infections, including meningitis, HIV
- Chronic alcohol or drug use
- Depression
- Developmental abnormalities
Ram: According to the Mayo Clinic, memory loss can be prevented by: 1) physical activity/exercise, 2) staying mentally active, 3) being socially active, 4) eating a healthy diet, 5) leading a stress-free life and 6) sleeping well.
There are so many scientific studies that indicate benefits of yoga (asanas, meditation and pranayama) in combating stress, keeping the individual physically and mentally stable and active, improving the digestive capacity and also helping in the sleeping process, all of which will result in combating age-associated memory loss. Yoga does this through multiple cellular mechanisms.
Nina: How can yoga help prevent strokes?
Ram: Yoga (asanas, meditation and pranayama) has been shown to improve the health of the heart and blood vessels, reduce blood pressure, reduce arrhythmia, reduce anxiety and depression, and improve metabolic parameters including blood lipid profiles all of which help in keeping stroke at bay
Nina: How can yoga help reduce chances of getting Alzheimer’s Disease?
Ram: In a recent study involving patients with early signs of Alzheimer’s disease (AD), it was shown that Yoga and Meditation increased functional connectivity in the areas involved in memory and also decreased the early degenerative changes that are typically seen in these regions, suggesting that Yoga and meditation have a positive impact on the regions of the brain related to AD. According to one Harvard researcher, yoga and meditation need to be included as part of the treatment regiment for dementia and Alzheimer’s patients. All the above-mentioned risk factors for stroke including hypertension, atherosclerosis, abnormal lipid profile, and stroke can trigger (AD). Since Yoga has been proven to improve all these conditions, in turn it can also reduce the onset and/or severity of AD.
Nina: How about general mental acuity? Can yoga help us stay mentally sharp as we age?
Ram: Yes, there are numerous studies that show that practice of yoga (asanas, meditation and pranayama) has beneficial effects on the emotional well-being and general mental acuity without any of the side effects. It’s no wonder that a recent article in Yoga Journal on yoga’s effects on mental acuity was aptly entitled Yoga-Better than Prozac. That in itself sums up the power of yoga. Yoga increases brain chemicals such as endorphins and enkephalins that contribute to a feel-good response and ward off mental stress. It is akin to stimulating the brain in a positive way, which results in optimal brain function all of which can keep an individual alert and sharp.
