| This view of the human brain illustrates a highly variable, abnormal pattern of blood flow. Brain blood flow is related to the degree of neural activity, and hence, brain function. As is the case with some individuals with ADHD, brain activity in specific areas is greatly reduced compared to controls. Areas of chronic dysfunction (functional lesions) appear as “holes” in the brain. Dysfunction often occurs in the prefrontal areas of the brain (top of image), and thus may be expected to cause significant loss of impulse control, decision making, learning ability, and emotional stability. |
