“Seafood consumption is promoted for its many wellness benefits fifty-fifty though it’s contaminated yesteryear mercury. Since mercury is a known neurotoxin, we wanted to arrive at upward one's heed whether seafood consumption is correlated amongst increased encephalon mercury levels inwards older adults, in addition to too whether seafood consumption or encephalon mercury levels are correlated amongst encephalon neuropathologies.
