BPPPV
episodic and resolves w position change
vestibular migraine
variant of migraine that can cause central vertigo. look for hx of migraines
how to differentiate btwn central and peripheral vertigo
nystagmus: in peripheral, unidirectional and rotational and doesn’t change direction w/ gaze, inhibited by fixing on a point, Frenzel glasses prevent fixation and bring out nystagmus. in central, it’s purely horizontal/vertical/rotational, doesn’t lessen when pt focuses on fixed point, persists for longer time.
