Neurodevelopmental disorders are a group of neurological disorders that affect
the development of the nervous system, leading to abnormal brain function which may affect emotion, learning ability, self-control, and memory. The effects of neurodevelopmental disorders tend to last for a person's lifetime, the signs and symptoms most often begin to show when a child is young, usually around preschool years. But in some, such as schizophrenia, symptoms may begin during the older teen years or in young adulthood.
Examples:
· ADHD
· Autism
What Causes Neurodevelopmental Disorders?
The causes of neurodevelopmental disorders are still largely unknown. In some cases, there may be a genetic factor; a neurodevelopmental disorder may run in certain families. Researchers also believe that certain things related to or that occurred during pregnancy may play a role in the development of these disorders, such as:
· Low birth weight
· Environmental contaminants, such as lead
· Fetal exposure to smoking, alcohol, recreational drugs, or medications during pregnancy
· Premature birth
