How Does Toxic Exposure Affect Cognitive Function?
The brain is particularly vulnerable to toxic exposure due to its high lipid content, extensive vascularization, and the presence of the blood-brain barrier, which, while protective, can be penetrated by certain toxins. Various substances, including heavy metals, industrial chemicals, and pharmaceutical drugs, can induce cognitive impairment by disrupting neuronal function, neurotransmitter systems, or brain structure.
