TAILIEUCHUNG - Chapter 022. Dizziness and Vertigo (Part 4)

In Ménière's disease, the direction of the fast phase is variableVertigo may be a manifestation of a migraine aura (Chap. 15), but some patients with migraine have episodes of vertigo unassociated with their headaches. Antimigrainous treatment should be considered in such patients with otherwise enigmatic vertiginous episodes. Vestibular epilepsy, vertigo secondary to temporal lobe epileptic activity, is rare and almost always intermixed with other epileptic Vertigo This is sometimes called phobic postural vertigo and is usually a concomitant of panic attacks (Chap. 386) or agoraphobia (fear of large open spaces, crowds, or leaving the safety of home). It should be suspected in patients. | Chapter 022. Dizziness and Vertigo Part 4 In Meniere s disease the direction of the fast phase is variableVertigo may be a manifestation of a migraine aura Chap. 15 but some patients with migraine have episodes of vertigo unassociated with their headaches. Antimigrainous treatment should be considered in such patients with otherwise enigmatic vertiginous episodes. Vestibular epilepsy vertigo secondary to temporal lobe epileptic activity is rare and almost always intermixed with other epileptic Vertigo This is sometimes called phobic postural vertigo and is usually a concomitant of panic attacks Chap. 386 or agoraphobia fear of large open spaces crowds or leaving the safety of home . It should be suspected in patients so incapacitated by their symptoms that they adopt a prolonged housebound status. Most patients with organic vertigo attempt to function despite their discomfort. Organic vertigo is accompanied by nystagmus a psychogenic etiology is almost certain when nystagmus is absent during a vertiginous episode. The symptoms often develop after an episode of acute labyrinthine dysfunction. Miscellaneous Head Sensations This designation is used primarily for purposes of initial classification to describe dizziness that is neither faintness nor vertigo. Cephalic ischemia or vestibular dysfunction may be of such low intensity that the usual symptomatology is not clearly identified. For example a small decrease in blood pressure or a slight vestibular imbalance may cause sensations different from distinct faintness or vertigo but that may be identified properly by provocative testing techniques see below . Other causes of dizziness in this category are hyperventilation syndrome hypoglycemia and the somatic symptoms of a clinical depression these patients should all have normal neurologic examinations and vestibular function tests. Depressed patients often insist that the depression is secondary to the dizziness. Approach to the Patient .
