Neuroscience: Memory loss is reversible with training

Researchers at Sweden's Karolinska Institute have shown that
intensive brain training leads to a change in the number of dopamine D1 receptors in the cortex.

Their results can be of significance to the development of new treatments for patients with cognitive impairments, such as those related to ADHD, stroke, chronic fatigue syndrome and ageing.

"Changes in the number of dopamine receptors in a person doesn't give us the key to poor memory," says Professor Lars Farde, one of the researchers who took part in the study. "We also have to ask if the differences could have been caused by a lack of memory training or other environmental factors. Maybe we'll be able to find new, more effective treatments that combine medication and cognitive training, in which case we're in extremely interesting territory."
Of course, the brain can only be trained by first reaching and persuading the mind.

This is good news for seniors struggling with memory loss.
