Experts have investigated genetic and environmental causes for ADHD. Some children may inherit a biochemical condition, which influences the expression of ADHD symptoms. Other children may acquire the condition due to abnormal fetal development, which has subtle effects on brain regions that control attention and movement. Recently, scientists have uncovered research based on brain imaging to localize the brain areas involved in ADHD and have found that areas in the frontal lobe and basal ganglia are reduced by about 10 percent in size and activity in ADHD children. Recent research based on genetic mechanisms has focused on dopamine as the primary neurotransmitter involved in ADHD. Dopamine pathways in the brain, which link the basal ganglia and frontal cortex, appear to play a major role in ADHD.
