"Normal" MRI scan accompanied by dizziness—warning sign of posterior stroke

Posterior circulation strokes (PCSs), which occur in the hind side of the brain, represent approximately 20% of all strokes. And yet, when compared to anterior strokes (those on the front side of the brain), they are almost three times more likely to be missed. The most common symptoms that lead to a misdiagnosed PCS are dizziness and vertigo. There is also overreliance on MRI scans, as there might be a short time interval between the appearance of symptoms and the first MRI.
