Chronic recurrent attacks of vertigo, not associated with any auditory or neurological symptoms, are a common reason for referral to our neurotology clinic. Even after an extensive neurotological evaluation, some cases remain undiagnosed. We prospectively evaluated 72 consecutive patients who presented to the clinic with isolated recurrent vertigo of(More)
NGFI-C is an early response gene which encodes a Cys2/His2 zinc finger protein. NGFI-C has previously been demonstrated to be inducible in PC12 cells after NGF stimulation. This study sought to localize this gene in somatosensory cortex, and investigate its possible induction by physiological and seizure stimuli. To determine if NGFI-C message levels are(More)
BACKGROUND In case reports, migraine headaches have been associated with fluctuating low-frequency hearing loss and sudden, unilateral hearing loss. Auditory symptoms associated with migrainous infarction have not previously been emphasized. OBJECTIVE To describe migrainous infarction presenting with acute auditory symptoms. DESIGN Case reports.

The incidence of atypical handedness (left-handedness and ambidexterity) in patients with epilepsy, particularly its association with major clinical factors, is not well established. We evaluated a full range of clinical variables in 478 patients with epilepsy from the United States and Korea. With the Edinburgh Handedness Inventory, handedness was(More)
Older adults perform much like younger adults on language. This similar level of performance, however, may come about through different underlying brain processes. In the present study, we evaluated age-related differences in the brain areas outside the typical language areas among adults using a category decision task. Our results showed that similar(More)
We describe a patient with seizures arising from right anterior-inferior frontal lobe presenting as myoclonic epilepsy. A 19-year-old man had experienced frequent paroxysmal bilateral myoclonic jerks involving his upper arms, shoulders, neck, and upper trunk since the age of 10. His baseline EEG showed intermittent right frontal spikes, and his ictal EEG(More)
The gene for human apolipoprotein E (APOE) is found on the long arm of chromosome 19 (19q13.2) and exists in three common allelic forms, epsilon2, epsilon3, and epsilon4. The APOE epsilon4 allele is overrepresented in Alzheimer's disease (AD) and is accepted as a genetic risk factor. Some studies reported a protective effect of the APOE epsilon2 allele for(More)
