Haemorrhagic stroke related to the use of 4-fluoroamphetamine
We report on two patients who presented with headache and mild hypertension after 4-FA use. Patient A developed one-sided weakness and decreased consciousness after a few hours. A computed tomography scan showed a left-sided intracerebral haemorrhage. Because of life-threatening cerebral herniation, haematoma evacuation was performed. Postoperatively, she suffered from a right-sided hemiparalysis and severe aphasia, requiring clinical rehabilitation. Patient B had a subarachnoid haemorrhage without neurological deficits. In total, 939 4-FA-intoxicated patients were registered. These patients used 4-FA alone (44%) or in com...

Contribution of EEG in transient neurological deficits
AbstractIdentification of stroke mimics and ‘chameleons’ among transient neurological deficits (TND) is critical. Diagnostic workup consists of a brain imaging study, for a vascular disease or a brain tumour and EEG, for epileptiform discharges. The precise role of EEG in this diagnostic workup has, however, never been clearly delineated. However, this could be crucial in cases of atypical or incomplete presentation with consequences on disease management and treatment. We analysed the EEG patterns on 95 consecutive patients referred for an EEG within 7 days of a TND with diagnostic uncertainty. Patients were classifi...

Characteristics of hypertrophic pachymeningitis in patients with granulomatosis with polyangiitis
AbstractHypertrophic pachymeningitis (HP) is an important neurologic complication of granulomatosis with polyangiitis (GPA, formerly Wegener ’s granulomatosis). The aim of this study is to investigate the clinical features, radiological findings, and diagnostic pitfalls of GPA-related HP. A retrospective chart review was performed to screen patients diagnosed with GPA at Samsung Medical Center between 1997 and 2016. Neurologic manifest ation, laboratory findings, neuroimaging data, and clinical course were evaluated in all patients. Characteristics of patients with HP were compared to those of patients without HP. Sixty-...

Frequency of MELAS main mutation in a phenotype-targeted young ischemic stroke patient population
Abstract Mitochondrial diseases, predominantly mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS), may occasionally underlie or coincide with ischemic stroke (IS) in young and middle-aged individuals. We searched for undiagnosed patients with MELAS in a target subpopulation of unselected young IS patients enrolled in the Stroke in Young Fabry Patients study (sifap1). Among the 3291 IS patients aged 18–55 years recruited to the sifap1 study at 47 centers across 14 European countries, we identified potential MELAS patients with the following phenotypic features: (a) diagnosed cardi...
