This study compared magnetic resonance imaging size differences in several brain regions and neurocognitive function in a group of male and female children with attention-deficit/hyperactivity disorder (ADHD) with no comorbid learning disorders with a normal control group of children. The ADHD group demonstrated smaller total brain, superior prefrontal, and(More)
OBJECTIVE To determine to what extent magnetic resonance imaging (MRI), single photon emission computed tomography (SPECT), and magnetoencephalography (MEG) can provide objective evidence of brain injury in adult patients with persistent (>1 year) postconcussive symptoms following mild blunt head trauma. DESIGN A retrospective and blind review of imaging(More)
Relationships between repetitive behaviors (RBs) and associated clinical features (i.e., cognitive and adaptive functioning levels, sleep problems, medication use, and other behavioral problems) were examined in two groups (High nonverbal IQ > or = 97 versus Low nonverbal IQ < or = 56) of children with autism spectrum disorders (n = 14; mean age = 10 years,(More)
OBJECTIVE To investigate neurometabolite concentrations in right prefrontal white matter in children with attention-deficit/hyperactivity disorder (ADHD) and relations of neurometabolites with attention skill and frontal anatomy. METHOD Single voxel proton magnetic resonance spectroscopy ( H-MRS), quantitative morphometric analysis of left and right(More)
This study examined predictors of developmental outcomes in 17 children diagnosed with autism or PDD-NOS, who received generic treatment over a mean period of 37 months. Pre-treatment evaluations occurred at a mean age of 31 months with follow-up evaluations at a mean age of 69 months. Significantly different developmental trajectories were observed among(More)
BACKGROUND Neurodevelopmental evidence of the cerebellum's protracted course of postnatal development suggests that it is particularly sensitive to early toxic insult from cancer therapy. If this is the case, one would expect that there is a relationship between the pattern of neuropsychological and magnetic resonance imaging deficits and that both may(More)
Assessed survivors of childhood lymphoblastic leukemia (ALL) treated with intrathecal chemotherapy, using the Wide Range Assessment of Memory and Learning (WRAML), compared to controls without cancer, matched as closely as possible in age, SES, and gender. Mild, but consistent, deficits were found in both visual-spatial and verbal single-trial memory tasks.(More)
BACKGROUND Long-term survivors of acute lymphoblastic leukemia (ALL) are reported to have post-treatment neurological changes as well as neuropsychological changes. Few studies have investigated the relationship between magnetic resonance imaging (MRI) volumetric measurements of brain regions of interest and cognitive functioning. This study examined the(More)
This 5-year follow-up study examined the stability of adaptive functioning in two cognitive ability groups of children with an autism spectrum disorder (ASD). Nonverbal intelligence (NVIQ) was assessed at the time of this study and no participant changed cognitive group membership from the previous study (High NVIQ 97; Low NVIQ 56). In each group, adaptive(More)
Forty-two normal (25th to 75th percentiles of weight for age) and 47 "obese" (above the 90th percentile) infants, 4 to 9 months of age, were compared with regard to energy and macronutrient intake, breast-feeding history, age of introduction of solids, and maternal reliance on external feeding cues. The study failed to reveal characteristic group(More)
