Exposure to brain toxins such as lead and mercury can significantly impact neurological functioning, leading to behavioral changes. These toxins can interfere with normal brain development and functioning, particularly in young children whose systems are still developing. Symptoms may include alterations in mood, cognitive impairments, and difficulties with attention and impulse control.

Behavioral changes resulting from such exposure are often profound, affecting social skills, emotional regulation, and overall mental health. Unlike the other effects listed, such as skin irritation, respiratory issues, and vision problems, which are typically associated with different types of toxins or environmental exposures, the behavioral changes are specifically linked to the neurotoxic effects of substances like lead and mercury. Thus, understanding this connection is essential for recognizing the broader impacts of these toxins on health, particularly in vulnerable populations.
