BACKGROUND AND PURPOSE Dizziness is a common symptom in emergency and outpatient settings. The purpose of our study was to compare the diagnostic and therapeutic efficacy of CTA of the head and neck, contrast-enhanced MR imaging of the brain (CE-MR), and contrast-enhanced MR imaging of the internal auditory canals and temporal bones in patients with isolated dizziness, to determine which of the...

Recent studies showed a link between cerebral small vessel white matter disease (SVD) and dizziness: patients whose dizziness cannot be explained by vestibular disease show severe SVD and gait abnormalities; however, little is still known about how SVD can cause this symptom. The primary aim of this study is to examine the possible underlying causes of dizziness in neurovascular patients; this ...

Haberstick and colleagues [1], in a study published elsewhere in this issue, utilized a genetically informative sameand opposite-sex twin and sibling sample involving 2482 subjects in an attempt to tease out environmental and heritable differences in susceptibility for smoking and nicotine dependence. The focus was upon subjective responses to initial exposure to tobacco smoke using the Early S...

Since dizziness is such a common symptom in older people, the symptom may be dismissed as a normal aging phenomenon. On the other hand, the patient may be inappropriately given nonspecific treatment for dizziness such as meclizine or diazepam, which may worse...

Examination of the dizzy patient should include a search for neurological signs and symptpms careful observation nystagmus. Most symptoms are markers dizziness central origin. However, some them represent vestibular or other imbalances that cause dizziness. Nystagmus could also peripheral Careful examination can help in discriminating psychogenic (functional)

BACKGROUND Dizziness is a frequent complaint of patients with Parkinson's disease (PD), and orthostatic hypotension (OH) is often thought to be the cause. We studied whether benign paroxysmal positional vertigo (BPPV) could also be an explanation. AIM To assess the prevalence of benign paroxysmal positional vertigo in patients with Parkinson's disease, with and without dizziness. METHODS 30...
