<jats:p>It is now known that the brain and spinal cord (central nervous system-CNS) make a small
number of hormones that are called neurosteroids (NS). They are called steroids because their
chemical structure is similar to the corticosteroids. NS are, however, not a corticosteroid. Two
of them, pregnenolone and dehydroepiandrosterone (DHEA), are now available for chronic pain
care.</jats:p>
