Detailed explanation-1: -Within the brain, lead-induced damage in the prefrontal cerebral cortex, hippocampus, and cerebellum can lead to a variety of neurological disorders, such as brain damage, mental retardation, behavioral problems, nerve damage, and possibly Alzheimer’s disease, Parkinson’s disease, and schizophrenia.
Detailed explanation-2: -The researchers report two main findings: Childhood lead exposure among the U.S. population by 2015 was responsible for the loss of more than 824 million IQ points. That number equates to an average of 2.6 lost IQ points per U.S. adult.
Detailed explanation-3: -A powerful neurotoxin, lead prevents normal brain and nervous system development as children grow, leading to lower IQ as well as lasting attention and behavior disorders and poor performance in school.
Detailed explanation-4: -This leads to extreme intracranial pressure, which can result in encephalopathy and irreversible brain damage. It also affects visual-motor reasoning skills, causes deficits in attention and cognitive ability, and promotes brain cell death. The effects of having too much lead in the blood cannot be reversed.
