The most recent technologies of cerebral imaging provide new data about cerebral abnormalities in patients with diverse psychiatric disorders. These methods include computed tomography (CT), magnetic resonance (MRI), electro magnetic (EMEKG), functional magnetic resonance (MRIf), positron emission tomography (PET), single photon emission computed tomography (SPECT), quantitative electroencephalography (QEEG), and evoked potentials (Eps), among others. Illnesses such as anxiety disorders, depressive disorders, dementing disorders, obsessive compulsive disorder, schizophrenia, bipolar disorder, learning disorders, and attention-deficit/ hyperactivity disorder (ADHD), are now considered the result of an interaction between environmental factors and abnormal function and structure of the brain. Data obtained from studies in ADHD subjects indicate a biological basis for this disorder. The specific anatomical and functional alterations of the brain in these patients, has been possible thanks to neuro-imaging.
