Intravenous Dextroamphetamine and Brain Glucose Metabolism

Brain glucose metabolism in Rett Syndrome.

Rett syndrome is a progressive neurologic disorder affecting girls in early childhood with loss of achieved psychomotor abilities and mental retardation. Six sedated female patients (4 to 15 years of age) with a diagnosis of Rett syndrome were studied with [(18)F]fluorodeoxyglucose (FDG) and underwent positron emission tomography scanning of the brain. Relative tracer concentrations between dif...

Brain glucose metabolism in thalamic syndrome.

Regional brain glucose metabolism was studied in a case of postischaemic thalamic syndrome. Despite a normal density of the thalamus on MRI and CT images, a 17% relative hypometabolism was found in the posterior thalamus on the affected side. This observation of functional anomalies in the posterior thalamic complex in case of thalamic syndrome is compatible with a deregulated processing of pai...

Systemic chemotherapy decreases brain glucose metabolism

OBJECTIVE Cancer patients may experience neurologic adverse effects, such as alterations in neurocognitive function, as a consequence of chemotherapy. The mechanisms underlying such neurotoxic syndromes remain poorly understood. We here describe the temporal and regional effects of systemically administered platinum-based chemotherapy on glucose metabolism in the brain of cancer patients. MET...

Boosting brain glucose metabolism to fight neurodegeneration?

Alzheimer's disease (AD) is the main cause of dementia in the elderly population with increasing prevalence. Despite the huge efforts invested in AD research, no therapeutic breakthrough has been witnessed yet. Likely, novel approaches and sweeping ideas will be necessary to effectively treat AD. Nevertheless, the earlier the disease is detected the more efficacious the therapy is. Early detect...
