Study finds that age-related memory loss "can be reversed"

“WHERE ARE MY keys?” has to be one of the most common phrases heard in any household – but according to scientists, age-related memory loss can be reversed.

Truth Dive reports that researchers at the Yale University in Connecticut have discovered more about the cellular basis for such cognitive difficulties

The study showed that age-related changes take place in the activity of neurons in the prefrontal cortex (PFC).

This is the part of the brain that controls higher cognitive and executive functions.

A study by Amy Arnsten, Professor of Neurobiology and Psychology discovered that neurons in the PFC of young animals became weaker and fired less often as they aged.

This, says the Telegraph, is due to growing levels in older brains of a molecule called cAMP.

However, a medicine called guanfacine helped speed up these processes.

This medicine is usually used for treating hypertension in adults.

Tests are currently underway to see if guanfacine works on humans.
