BACKGROUND AND PURPOSE Transient ischemic attack (TIA) is a marker for early risk of stroke. No previous studies have assessed the use of urgent stroke prevention clinics for emergency department (ED) patients with TIA. We hypothesized that an ABCD2-based ED triaging tool for TIA with outpatient management would be associated with lower 90-day stroke rate than that predicted by ABCD2. METHODS...

BACKGROUND AND PURPOSE Some clinical models, like California ABCD and unified ABCD2 scores, are now available to predict the early risk of stroke after a TIA. Despite the transitivity of symptoms, DWI identified an area of acute brain ischemia in almost half of patients. It would be interesting to know how the presence of DWI abnormalities relates to clinical risk scores to plan other prognosti...

PURPOSE Cell transplantation of myelin-producing exogenous cells is being extensively explored as a means of remyelinating axons in X-linked adrenoleukodystrophy. We determined whether 3,3',5-Triiodo-L-thyronine (T3) overexpresses the ABCD2 gene in the polysialylated (PSA) form of neural cell adhesion molecule (NCAM)-positive cells and promotes cell proliferation and favors oligodendrocyte line...

BACKGROUND Several recent guidelines recommend assessment of patients with TIA within 24 hours, but it is uncertain how many recurrent strokes occur within 24 hours. It is also unclear whether the ABCD2 risk score reliably identifies recurrences in the first few hours. METHODS In a prospective, population-based incidence study of TIA and stroke with complete follow-up (Oxford Vascular Study),...

BACKGROUND AND PURPOSE The risk of stroke after a transient ischemic attack (TIA) for patients with a positive diffusion-weighted image (DWI), i.e., transient symptoms with infarction (TSI), is much higher than for those with a negative DWI. The aim of this study was to validate the predictive value of a web-based recurrence risk estimator (RRE; http://www.nmr.mgh.harvard.edu/RRE/) of TSI. ME...

X-linked adrenoleukodystrophy is a metabolic disorder arising from a mutation/deletion in the ABCD1 gene, leading to a defect in the peroxisomal adrenoleukodystrophy protein (ALDP), which inhibits the oxidation of very long chain fatty acids (VLCFAs). Thus, these VLCFAs accumulate. In a cerebral form of ALD (cALD), VLCFA accumulation induces neuroinflammation that leads to loss of oligodendrocy...

BACKGROUND AND PURPOSE There are scarce data on transient ischemic attack incidence in low- and middle-income countries. We aimed to measure transient ischemic attack incidence and the distribution of the ABCD2 risk score in Joinville, Brazil. METHODS In 2009 to 2010, using a multiple overlapping sources, we ascertained all first ever probable and definite transient ischemic attacks. RESULT...
