Affected functional networks associated with sentence production in classic galactosemia.

Patients with the inherited metabolic disorder classic galactosemia have language production impairments in several planning stages. Here, we assessed potential deviations in recruitment and connectivity across brain areas responsible for language production that may explain these deficits. We used functional magnetic resonance imaging (fMRI) to study neural activity and connectivity while participants carried out a language production task.

Quantitative MR and cognitive impairment in cryptogenic localisation-related epilepsy.

For patients with chronic cryptogenic localisation-related epilepsy (CLRE), conventional MRI does not provide measures to discern between patients with or without cognitive complaints. We investigated, in a preliminary study, whether it is possible to detect cerebral biomarkers of cognitive impairment in patients with CLRE using sensitive quantitative MRI techniques. Neuropsychological assessment and quantitative 3.

Working memory deficits in high-functioning adolescents with autism spectrum disorders: neuropsychological and neuroimaging correlates.

Working memory is a temporary storage system under attentional control. It is believed to play a central role in online processing of complex cognitive information and may also play a role in social cognition and interpersonal interactions. Adolescents with a disorder on the autism spectrum display problems in precisely these domains.

Functional MRI in chronic epilepsy: associations with cognitive impairment.

Chronic epilepsy is frequently accompanied by serious cognitive side-effects. Clinical factors are important, but cannot account entirely for this cognitive comorbidity. Therefore, research is focusing on the underlying cerebral mechanisms to understand the development of cognitive dysfunction.
