Lower than normal total brain volume. Reduced size of some parts of the brain. Slower-than-normal cortical maturation up to adult life. Reduced cortical thickness in adults especially of the cortical network responsible for focused attention.
How do ADHD brains develop differently?
They found that brain size was different between the two groups. Children with ADHD had smaller brains by about 3 percent , although it is important to point out that intelligence is not affected by brain size.
