ScienceDaily for December 30, 2010 reported on causes and prevention of Dementia.
Neuroscientists had assumed that a mutation in the progranulin gene, which makes
the progranulin protein and supports brain neurons, was sufficient to produce a kind of dementia known as frontotemporal lobar degeneration (FTLD). But now an international team of scientists led by researchers at Mayo Clinic's campus in Florida have found another genetic factor they say appears to protect against the disorder in progranulin mutation carriers.
