How to protect your brain from dementia

No simple answers to dementia prevention but some clear signposts are starting to emerge.

How to protect your brain from dementia

This is not a simple question and there isn’t just one answer. Dementia is a term used to describe symptoms from a number of different illnesses, so different forms of dementia may require alternative approaches. However an article about how Jessica Langbaum keeps her brain young makes some points that we all can learn from. Jessica is the Associate Director of the Alzheimer’s Prevention Initiative at the Banner Alzheimer’s Institute in Phoenix, so she knows a thing or two about reducing the risk of developing dementia.

There is an enduring belief that activities such as Sudoku or app based brain training  can offer some benefit is the battle against neurodegeneration. But Dr Langbaum makes the point that any exercise as narrow in scope as single task brain training is probably too limited to be of significant benefit. So that while Soduko for example, might help to keep the parts of the brain linked to simple calculations in good working order, this may offer little protection against Alzheimer’s dementia. The presumption is that maintaining large areas of brain function at high levels of performance is likely to keep overall brain health for longer. This idea is often described at the use it or lose it hypothesis, that once we start to scale down the demands on our brain we may unwittingly increase the risks of permanently losing function and structure.

“regular meditators have been observed to have both younger brains and thicker cortex than non-meditators”

The use it or lose it approach isn’t an ultimate answer but it does give us some great signposts about how to maintain brain health. I have often considered that continued use of meditation into middle and old age by Buddhists may be directly linked to the anecdotal evidence suggesting lower rates of dementia in certain groups of meditators. Many long term Buddhists increase their meditation practice in retirement and can frequently be found working for a range of good causes in voluntary and paid capacities, even at advanced ages. There is research that suggests spiritual practice per se might have a preservative effect on cognitive function but I think we must also consider the more direct influence of meditation methods on the regular renewal of brain function and structure.

Many well established Buddhist meditation practices such as tonglen have been designed as mind training systems. Their original goal was almost certainly not to reduce the risks of dementia, but they have long been associated with increasing wisdom, clarity and compassion. From the neuroscience point of view this means the methods are linked to activity in several of the most important brain networks, such as those connected to empathy, memory, attention, visualization and planning. This is specifically why Brain Renewal Meditation (BRM) has been developed with reference to reliable traditional methods and is also supported with research from neuroimaging and cognitive psychology.

The best advice we can offer to reduce your risks of developing dementia is to,

  • start early, cognitive decline begins in our late 20s
  • stop smoking
  • keep your brain as active as possible for as long as possible
  • stay socially engaged
  • challenge yourself
  • stay physically active
  • watch your diet
  • try forms of brain training able to keep a range of brain structures firing

Brain Renewal Meditation (BRM) is a simple system developed by meditation expert and trained neuroscientist Stephen Gene Morris. It offers methods designed to improve brain health and slow down the rate of cognitive (brain) decline. Aspects of our brain function such as memory and attention begin to deteriorate in our late 20s, however most of us don’t start to notice any changes until we reach our 40s. The point of BRM is that there are a number of things we can do to slow or perhaps even reverse aspects of  cognitive decline at any point in our lives, even at 60, 70 or 80. If you have the capacity to concentrate there is a good chance that you can make a positive impact on your brain’s function and structure.

Meditation is probably the single most useful thing a person can do to help maintain brain health. There are hundreds of scientific studies that show an effect on cognitive performance linked to regular meditation. A key point to make is that different forms of meditation lead to different effects. BRM draws together elements of compassion, nondual and mindfulness meditation into one integrated practice. It is a secular practice which requires no previous experience of meditation, it can be undertaken sitting in any chair that allows you to keep your back straight. It can be practiced in a traditional meditation class or through online training in your own home.

Almost all of the evidence from neuroscience, psychology and traditional meditation systems points to our ability to improve our own brain function throughout our lives. For example a major strategic review of research into strategy-based cognitive training in older adults, strongly indicated than brain function can be enhanced even in middle and old age. The crucial point is that no mater what your age your brain remains plastic and can adapt to the demands of brain training in many forms, particularly meditation.
