What behavioral changes would early lead poisoning manifest in a child?

Hyperactivity is a key behavioral change associated with early lead poisoning in children. When a child is exposed to lead, it can affect their central nervous system, ultimately leading to difficulties in attention and increased levels of activity. This hyperactivity may manifest as an inability to stay still, difficulty concentrating, or impulsive actions that do not reflect the child's typical behavior.

It's important to recognize that lead poisoning can also impact cognitive functions and emotional regulation, which may lead to other behavioral issues later. However, in the early stages, hyperactivity is often one of the most noticeable signs, prompting further investigation into possible environmental causes of exposure to lead.
