What organ if affected by lead poisoning?

Lead poisoning primarily affects the nervous system, especially in young children. The developing brain is particularly susceptible to lead's toxic effects, and even low levels of lead can cause lasting cognitive and behavioral problems. Lead can damage neurons, impair neurotransmitter function, and disrupt the development of the nervous system. In adults, lead poisoning can lead to a range of neurological symptoms, including memory problems, headaches, mood disturbances, and decreased reaction times.
