Incoherence of Neuroimaging Studies of Attention Deficit/Hyperactivity Disorder

Abstract: Neuroimaging studies have been conducted with increasing frequency in recent years in attempts to identify structural and functional abnormalities in the brains of persons with attention deficit/hyperactivity disorder. Although the results of these studies are frequently cited in support of a biologic etiology for this disorder, inconsistencies among studies raise questions about the reliability of the findings. The present review shows that no specific abnormality in brain structure or function has been convi… Show more

“…These studies have shown inconsistent abnormalities in frontal lobe activation and frontostriatal dysfunction in children, adolescents and adults with ADHD during inhibitory control tasks. [28][29][30] Other studies have reported more global dysfunction of brain activation in children with ADHD. 31 Other areas of attention deficit research CPT tests have also been used widely in different areas of attention deficit research, such as EEG alpha asymmetry, event-related potentials, EEG-vigilance, EEG complexities, the cortisol response to stress, effects of lead poisoning, effects of prenatal smoking, effects of Caesarean section birth, and other environmental aetiological factors.…”

“…Since then, although inattention, hyperactivity, and impulsivity have been the object of numerous categorizations and conceptualizations (Baumeister & Hawkins, 2001), brain anomalies have remained at the core of etiological models of the disorder. Researchers have sought to confirm the biological roots of ADHD using a variety of methods, such as behavioral and molecular genetics, neuropsychology, drug challenges, and investigation of environmental factors likely to affect brain structure and functioning.…”
