ABSTRACT

Deficit attention disorder with hyperactivity (DADH) is the most common psychiatric disorder in children. There are three types of DADH. The symptoms implied different neuroanatomy and neurochemical systems, therefore is least likely finding a unique cause.
The findings in neuroimaging studies in children with DADH mainly involve the frontal lobe and the basal ganglia.
We included twenty-two male children, recently diagnosed, without previous pharmacological treatment and without any other disease. A cranial magnetic resonance study was performed with morphological sequences and bilateral univoxel spectroscopy of the frontal lobes, caudate nuclei and sensorimotor areas.
There were no significative differences between the patients and the controls. The qualitative analysis of the spectroscopy showed decreased choline levels in the sensorimotor areas in all groups. Quantitative analysis did not detected differences between controls and patients. Moreover, significant differences were found dividing the DADH group in subgroups.
