Background Attention deficit and hyperactivity disorder (ADHD) is a disorder of the brain characterized by periods of inattention, hyperactivity and impulsive behavior. We aimed to evaluate the role of MRI of the brain in children with ADHD. Materials and Methods This prospective study included 100 children with clinical diagnosis of attention deficit and hyperactivity disorder according to the...

Speech processing requires the temporal parsing of syllable order. Individuals suffering from posterior left hemisphere brain injury often exhibit temporal processing deficits as well as language deficits. Although the right posterior inferior parietal lobe has been implicated in temporal order judgments (TOJs) of visual information, there is limited evidence to support the role of the left inf...

The posterior parietal lobe is known to play some role in a far-flung list of mental processes: linking vision to action (saccadic eye movements, reaching, grasping), attending to visual space, numerical calculation, and mental rotation. Here, we review findings from humans and monkeys that illuminate an untraditional function of this region: memory. Our review draws on neuroimaging findings th...

Numerous functional neuroimaging studies have observed lateral parietal lobe activation during memory tasks: a surprise to clinicians who have traditionally associated the parietal lobe with spatial attention rather than memory. Recent neuropsychological studies examining episodic recollection after parietal lobe lesions have reported differing results. Performance was preserved in unilateral l...

Visuospatial construction, traditionally viewed as a putative parietal function, also requires sustained attention, planning, organization strategies and error correction, and hence frontal lobe mediation. The relative contributions of the frontal and parietal lobes are poorly understood. To examine the contributions of parietal, frontal lobes, as well as right and left cerebral hemispheres to ...

Background and Purpose: Mild cognitive impairment (MCI) is by many considered a prodromal phase of Alzheimer’s disease (AD). We used voxelbased morphometry (VBM) to find out whether structural differences on MRI could offer insight about the development of clinical AD in patients with amnestic MCI at three years follow-up. Methods: Twenty-four amnestic MCI patients were included. After three ye...
