Lead poisoning causes changes in the chemistry of the nervous system. These changes in turn affect the nerves and the communication between cells. This can result in detectable differences in the way the brain functions. Thinking, learning, memory, and the ability to focus attention can be adversely affected. The speed at which the muscles respond can be slowed. Hearing can be mildly impaired, as can the ability to listen and to speak. The sense of balance, as well as motor and hand-eye coordination, can be disturbed.
