A recent article in Neuroscience News reviews various ways that meditation helps with memory function:
An area of the brain known as the hippocampus, critical to memory function, tends to shrink with age. Reducing stress, to which meditation contributes significantly, slows down this process.
a longer-term Meditation practice tends to make the thickness of the cerebral cortex (also known as cortical thickness), increase, in several areas critical to memory.
Working memory, the processes in the brain that store short-term information, is improved by meditation.
I discussed other benefits of meditation here, and gave advice on how to get started here. It’s nice to know researchers are continuing to add to the list of benefits
