The term 'vascular dementia' (VaD) corresponds to a clinicoradiological syndrome that can be defined with more or less restriction. VaD can result from: (1) cortical or subcortical ischemic lesions related to the occlusion of large vessels, (2) lacunar infarcts with or without white-matter lesions at the subcortical level related to small-vessel diseases, (3) ischemic lesions related to hypoper...

Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic disorder that presents with variable symptoms and symmetrical abnormal white matter signaling most commonly of the occipital parietal lobes on magnetic resonance imaging (MRI). PRES, also known as posterior leukoencephalopathy (RPLS) associated hypertension. Hypomagnesemia’s association PRES has been rarely reported. Here,...

The objective was to follow up a cohort of acidotic full-term infants with or without hypoxic ischemic encephalopathy (HIE) and determine if at 7 years they displayed any neurodevelopmental delays. Children (n=44) were divided according to those with mild (n=25) or severe (n=19) acidosis and were then further subdivided into those with or without HIE. Participants were assessed using the Wechsl...

OBJECTIVE: To review the literature on the hypoxic-ischemic syndrome, emphasizing its physiopathology, clinical manifestations, and treatment. SOURCES: Electronic search in the Medline and LILACS databases, with selection of the most relevant articles. SUMMARY OF THE FINDINGS: The hypoxic-ischemic syndrome is a multisystem disease with generalized manifestations. The physiopathology is based on...

Hypoxic-ischemic encephalopathy (HIE) is the most important cause of cerebral damage and long-term neurological sequelae in the perinatal period both in term and preterm infant. Hypoxic-ischemic (H-I) injuries develop in two phases: the ischemic phase, dominated by necrotic processes, and the reperfusion phase, dominated by apoptotic processes extending beyond ischemic areas. Due to selective i...
