Definition

Zinc accumulation refers to the excess build-up of zinc in the body, particularly affecting neurological health. It can result from dietary intake, supplementation, or impaired metabolic processes.

5 Must Know Facts For Your Next Test

1. Excessive zinc accumulation can lead to neurotoxicity and impair cognitive functions.
2. Zinc plays a crucial role in synaptic signaling and neurotransmitter function.
3. Dysregulated zinc levels are associated with neurological disorders such as Alzheimer's disease and Parkinson's disease.
4. The blood-brain barrier regulates zinc levels in the brain, but excessive amounts can disrupt this balance.
5. Dietary sources high in zinc include meat, shellfish, legumes, seeds, nuts, dairy products, and whole grains.
