Vertigo Lawrence Pike James Street Family Practice

    2. Definition An illusion or hallucination of movement which is usually rotation, either of oneself or the environment

    3. Major Causes in General Practice 3 Major Causes: Vestibular Neuronitis Benign Positional Vertigo Meniere’s

    4. Vestibular Neuronitis

    5. Vestibular Neuronitis - Features • Commonly occurs on first awakening • Nausea is marked and almost universal • 57% evidence or recent viral infection • Fine horizontal or rotatory nystagmus

    6. Vestibular Neuronitis - Course • Attacks become sequentially shorter and if not then consider another diagnosis • Vertigo symptoms usually resolve over a few days as vestibular compensation occurs

    7. Vestibular Neuronitis - Management • Symptomatic treatment for first few days only • Vestibular drugs delay compensation

    8. Vestibular Neuronitis - Prognosis • Excellent • 5% progress to Benign Positional Vertigo

    9. Benign Positional Vertigo

    10. Benign Positional Vertigo - Features • Recurrent • Brought on by changes in head position • Episodes last seconds, never >5 mins • Onset late middle age usually • Females : Males = 2 : 1 • Typically turning over in bed, bending over and straightening, extending neck

    11. Benign Positional Vertigo - Management • Vestibular sedatives should be avoided where the vertigo becomes chronic as they supress vestibular feedback crucial for compensation and symptomatic recovery

    12. Benign Positional Vertigo - Brandt-Daroff Exercises • Simple repositioning exercises and are appropriate for less severe BPV • Complete relief within 3 to 14 days

    13. Benign Positional Vertigo - Brandt-Daroff Exercises • Sit patient on couch with eyes closed • Tilt whole upper body laterally towards lesion until lateral aspect of occiput lies on the bed. Maintain until vertigo subsides • Sit patient upright for 30 seconds • Repeat on then other side and rest head for 30 seconds • Repeat every 3 hours during day

    14. Menieres

    15. Menieres - Features • Hearing Loss • Tinnitus • Vertigo • Sensation of fullness or pressure in ear • Fluctuates and episodic, lasts hours • Unilateral • 20-50 years Familial predisposition

    16. Menieres - Course • Progressive • Early on predominant Vertigo with Deafness but normal hearing between • Later on hearing loss stops fluctuating and becomes progressively worse

    17. Menieres - Management • Referral to ENT Specialist has been recommended for every case of vertigo and hearing loss to exclude acoustic neuroma • Betahistine with or without diuretic is favoured current treatment

    18. Vertigo Final Notes • Vertigo with Diplopia is likely to be a vascular event • Vestibular sedatives are not recommended on a prolonged basis for any type of vertigo
