Evidence indicates that Brain structure and function can be maintained and augmented through particular forms of meditation.
Taking responsibility is the key to brain health
In recent decades psychology and neuroscience have made progress in explaining brain functions and dysfunctions. But we still know far too little about how the human brain ages. In studies linked to meditation and mindfulness the vast majority of research (I’d estimate in excess of 80%) has been undertaken with participants under the age of 25. There is some research interest in people of retirement age and with people suffering from particular health problems. But if you trawl the academic databases for investigations of the effects of meditation on people in the 30 to 65 age range you will find relatively few studies and even fewer reliable conclusions. The irony of this lack of research is that this is the age at which cognitive decline is supposed to happen (from the early 30’s onward). It’s also supposed that dementia typically starts its journey in middle age, perhaps decades before the full symptoms manifest.
A concept that can be found throughout psychology and neuroscience is ‘age related cognitive decline’; the general correlation between age and brain function/structure. It is a pretty uncontroversial idea, we all carry around the stereotype that as we get older we can expect to experience ‘senior moments’, a lowering in cognitive ability. I’m not going to dispute that this does appear to be the pattern. But my experience of meditation is that the rate of cognitive decline is flexible. I’ve seen the transformation in people’s ability to think, problem solve and remember. There is also some evidence from neuroscience to support the premise that decline in cognitive function can be influenced by a range of activities, meditation in particular. This is not to say that meditation may keep your brain forever young, rather that you have a degree of control over how your own brain ages.
Whilst certain forms of meditation do appear to be linked to improved cognitive function, the neuroscience is at a preliminary stage. It’s clear that different forms of meditation have different effects, and meditation isn’t the only thing we can we can do to influence the development of brain function and structure. It should always be considered that just as some activities appear to support brain rejuvenation, others have the opposite effect. Anyone over the age of 30 is likely to benefit from maintaining, and where possible increasing cognitive function, meditation however is a cornerstone of this process. Keeping your body in good shape takes some time, effort and commitment, this is also true of mind training

Is spirituality a factor in better health? If so does this have implications for meditation?
In a recent article William Sears wrote about the health benefits of being on the spiritual path. He contends that religious belief may be linked to a longer and happier life as well as good all round general health. The idea is probably supported by the experience of many traditional meditation teachers. This has generally been my own experience, people that commit to meditation in a Buddhist context seem to achieve an improvement in the quality of their lives; notwithstanding their spiritual goals.
There is a particular paradox at work here, improved conditions for oneself being linked to a lessening of the attention on oneself. Most people that I have meditated with appeared to have come to meditation to achieve a particular goal, typically linked to health and wellbeing. In this regard as I become more experienced, the less attention I pay to the reasons why someone wants to meditate. I would of course hesitate to teach meditation to someone who explicitly wanted to pursue a negative goal, this fortunately has never happened. But the point is that an authentic meditation method is forgiving of a degree of selfishness. Experience has taught me that an openness to the method is the key to reaping the health and wellbeing rewards of meditation practice.
So I would generally advise people who seek the benefits of meditation to simply practice. Agonizing over the authenticity of one’s own meditation is much less productive that just meditating. Clearly if someone is seeking to enter a spiritual path a degree of understanding is necessary. But if you simply want to feel better, most of your energy should be directed towards mind not ego.
Typically a meditation master discourages students from commenting on other people’s meditation achievements. This is useful in itself but it almost certainly helps to stop self examination, as well as as the critiquing of the people you might be meditating with. As a meditation scientist I’m inclined to think this is linked to the balancing of our intrinsic and extrinsic networks. However much more importantly it’s simple to test for yourself. Try to make a point of criticizing others less for a week, see if this has an effect on your own self criticism.
Meditation for health and wellbeing are positive goals to maintain, meditating for the health and wellbeing of yourself and others may be a more effective method.
Evidence of a lasting impact of meditation
As the body of research into meditation grows, the evidence of the actual effect of meditating increases. Western science rarely provides clear evidence of causality, particularly when it comes to understanding complex human behavior such as meditation. However there are a significant number of studies that document a relationship between meditation and brain activity.
In 2012 a study was carried out into the effects of meditation (mindfulness and compassion methods) that had a direct effect on the response of a part of the brain called the amygdala to emotional stimuli. The headline findings from this study are that the changes to the amygdala response were measured while people were not meditating, meaning that the effects of an eight week meditation programme were experienced outside of meditation practise. Meditation had been able to exert an influence on people’s brains during a non-meditative state.
