How Meditation Effects The Human Brain

Often we are not aware of the pleasure of sitting around doing nothing, letting the mind wander in the here and now, it is on the beach, getting carried away by the sound of the waves; in the bush next to a stream, or simply at home. It is not only a relaxing experience that helps us balance our thoughts after a day's work and to reconnect; if we also pay attention to our thoughts, to some external object or our consciousness, we will be meditating. Etymologically, meditation comes from the Latin meditatio, defining a type of intellectual exercise.

Many studies indicate that there is a relationship between cognitive impairment and Alzheimer's Disease. You see, cognitive impairment does not only affect children, it can also affect anyone at any age, because one of the causes of cognitive impairment is thought to be a head injury that impacts a critical part of the brain. This is sometimes termed "Mild Cognitive Impairment", or MCI, might some studies indicate may represent some kind of "transitional stage" between normal aging and dementia. The problem with stating this definitively, however, is that progression from one stage to another is typically very slow, and as a result some people may die of natural causes before experiencing full scale Alzheimers disease.
