3.  What is the most likely suggested pathophysiology of MARD? Dysfunction of monoaminergic pathways important for migraine, anxiety, and central vestibular system. Abnormal firing of GABA-controlled pathways, blocking signal transmission to the ears. Basilar-type migraine, with lack of blood flow to the brain and the ears. All of the above

7.  Which of the following sequence of onsets of dizziness disorders is most likely to occur? SCD that evolves into vestibular neuritis and finally becomes Meniere’s disease. Vestibular neuritis that transitions into BPPV and finally becomes PPPD. BPPV that is followed by Meniere’s disease and finally SCD. Meniere’s disease that evolves into SCD and finally becomes vestibular neuritis.

8.  According to data derived from patients completing the Dizziness Symptom Profile (DSP), what percentage of patients present with multiple vestibular diagnoses? 1% 32% 68% 100%

9.  Which of the following was the most common co-occurring diagnosis based on the DSP data? Benign Paroxysmal Positional Vertigo Vestibular Migraine Meniere’s Disease Superior Canal Dehiscence

10.  Which of the following six common vestibular disorders is the most likely to have vestibular migraine as a co-occurring disorder? Meniere’s Disease Persistent Postural-Perceptual Disorder Vestibular Neuritis Superior Canal Dehiscence
