Examples of neurobehavioral effects include depression, trouble concentrating, impairments in motor skills, diminished memory and post-traumatic stress disorder, explains Nolo. Fatigue, dementia and sleep-related problems also fall under the category of neurobehavioral effects.
Exposure to certain hazardous chemicals, such as trichloroethylene, can produce neurobehavioral effects, notes the National Center for Biotechnology Information. Another environmental cause of neurobehavioral effects is poverty, according to the American Psychological Association. People living in developing countries exhibit a much higher prevalence of mental retardation than people in high-income nations. Additionally, research finds that children who grow up in low-income families are more likely to have smaller hippocampi and amygdalae, two parts of the brain.
