Concussion, dementia, and sleep deprivation produce similar changes to your brain’s architecture as determined by a novel MRI imaging analysis.  Oregon investigators now present data from their study of 56 Afghanistan war vets and suggest possible therapeutic approaches to TBI and dementia.

Their imaging data shows a correlation between battle brain trauma and enlargement of perivascular spaces that fill with metabolic waste as the result of brain cell damage.  This same material collects with advancing age and dementia, but sound sleep helps flush it away.

The researchers propose that their imaging technique provides a diagnostic and monitoring tool for brain injuries and a method for documenting improvement driven by improved sleep.
