Title: Meditation and neurodegenerative diseases.

Summary: Meditation research is now so fragmented that only by taking an overview can a fuller understanding of what we know be arrived at. In research literature these overviews are called strategic reviews or meta studies. Newberg and colleagues offer their perspective on what we know about how our brain functions decline and what we can do to stop it. The authors set out the broad definitions for Alzheimer’s Disease, Frontotemporal lobar dementia (FTLD) including Pick’s Disease and Parkinson’s Disease, and discuss the potential of meditation to help people with declining brain function.

There is no shortage of evidence for a relationship between meditation and both functional and structural change in the brain, but the devil really is in the detail. In common with a wide range of other behaviours, meditation will have an effect on the brain, but understanding which meditation methods create which effects is not a simple matter. This meta study describes the influence of meditation into two areas, attention and memory, but it also includes element of cognition more generally. The paper illustrates evidence for a relationship between meditation and improvements in performance in all three areas (attention, memory and other cognitive functions). Some of these improvements have been linked to recorded physical changes to the brain. Individual studies are discussed demonstrating quite specific effects from meditation practices. For example that vipassana meditation appears to improve working memory and focused attention methods may help sustained visual attention.

Unfortunately there is almost no replication of the cited effects (replication being identical studies reporting the same results). This report also reduces all meditation to a singular family of mind training, evidence suggests that this is an unscientific approach. Grouping together methods from kundalini, tantra, sutra with MBIs in a meta review is fraught with difficulty, particularly as robust theoretical frameworks for these practices don’t exist in neuroscience or cognitive psychology. However in defence of the authors, meditation has been researched in the west for at least 45 years and attempts to understand and review progress should be welcomed.
