1 CASE STUDY PSYCHOGENIC VESTIBULAR DISORDER Date = 06/05/08

2 Summary of Referral Information Summary of Letter from GP; ‘ This young man has had unsteadiness and vertigo over the last six months. He has failed to respond to betahistine and prochloroperazine and has become very fed-up and down with this. He has also had panic attacks. Interestingly, he had a similar problem when his parents were separating as a child. He is a fairly self-critical and tense individual who has low self esteem. I would be most grateful if you could advise further on his dizziness.

10 General Tests Otoscopy Otoscopy Audiometry Audiometry Tympanometry Tympanometry GHQ questionnaire GHQ questionnaire

11 Balance Assessment Spontaneous and Gaze Assessment Spontaneous and Gaze Assessment Saccades Saccades Smooth Pursuit Smooth Pursuit Dix Hallpike Dix Hallpike Head Roll testing Head Roll testing Caloric testing Caloric testing

12 Summary of Results Otoscopy - No abnormalities observed bilaterally Otoscopy - No abnormalities observed bilaterally Audiometry -Thresholds within normal limits bilaterally Audiometry -Thresholds within normal limits bilaterally Tympanometry - Raised middle ear compliance on right and pressure within normal limits bilaterally Tympanometry - Raised middle ear compliance on right and pressure within normal limits bilaterally Gait and balance – Informal observation revealed normal gait and no obvious unsteadiness on walking into clinic Gait and balance – Informal observation revealed normal gait and no obvious unsteadiness on walking into clinic Spontaneous and Gaze – did not reveal any nystagmus or symptoms Spontaneous and Gaze – did not reveal any nystagmus or symptoms Saccades and Pursuit – did not reveal any nystagmus or symptoms Saccades and Pursuit – did not reveal any nystagmus or symptoms

13 Results Continued.. Dix-Hallpike and Head Rolls = did not reveal any nystagmus or symptoms, negative in all positions Dix-Hallpike and Head Rolls = did not reveal any nystagmus or symptoms, negative in all positions Warm Calorics (44º) - symmetrical – No significant Canal Paresis or DP observed Warm Calorics (44º) - symmetrical – No significant Canal Paresis or DP observed GHQ = score = 9 (low for depression) GHQ = score = 9 (low for depression) the 28-items "scaled" version (has four subscales: somatisation, social dysfunction, anxiety, and depression) the 28-items "scaled" version (has four subscales: somatisation, social dysfunction, anxiety, and depression)

14 Conclusions No evidence of peripheral or central cause of dizziness No evidence of peripheral or central cause of dizziness Complete set of normal vestibular testing results Complete set of normal vestibular testing results Suggests panic and anxiety may be contributing significantly to the patient’s symptoms Suggests panic and anxiety may be contributing significantly to the patient’s symptoms May be Psychogenic in nature May be Psychogenic in nature

15 Psychogenic Dizziness No organic disease is present No organic disease is present Large amount of psychological disability in persons with vertigo Large amount of psychological disability in persons with vertigo Difficult diagnoses to reach Difficult diagnoses to reach

16 Clinical Manifestations dizzy sensation is typically persistent and continuous dizzy sensation is typically persistent and continuous punctuated by episodes of hyperventilation punctuated by episodes of hyperventilationhyperventilation provocative factors may be identified, such as the presence of crowds, driving, or being in confined places provocative factors may be identified, such as the presence of crowds, driving, or being in confined places “manifestations of anxiety, including apprehension, dread, nervousness, tension, restlessness, and autonomic manifestations” “manifestations of anxiety, including apprehension, dread, nervousness, tension, restlessness, and autonomic manifestations” Episodes are often poorly described Episodes are often poorly described Panic attacks Panic attacks (all fits in with current patient)

17 Management Psychotherapeutic approaches such as cognitive behavioural therapy Psychotherapeutic approaches such as cognitive behavioural therapy Medications – to treat depression and anxiety (beta- blockers) Medications – to treat depression and anxiety (beta- blockers) Perform tests - reassure the patient that no organic disease is present Perform tests - reassure the patient that no organic disease is present Referrals to Psychiatry / Neurology Referrals to Psychiatry / Neurology Vestibular Rehabilitation – possible breathing control exercises Vestibular Rehabilitation – possible breathing control exercises Multi-disciplinary team which includes ENT, audiologists, hearing therapist, clinical psychologists, and physiotherapists Multi-disciplinary team which includes ENT, audiologists, hearing therapist, clinical psychologists, and physiotherapists

18 Other Useful tests… Hyperventilation Test - The early literature suggested that this was a sign of psychogenic (psychiatric) disturbance (Drachman and Hart, 1972), but later workers using better technology to monitor eye movements suggest that nystagmus induced by hyperventilation is a good sign of vestibular disease Hyperventilation Test - The early literature suggested that this was a sign of psychogenic (psychiatric) disturbance (Drachman and Hart, 1972), but later workers using better technology to monitor eye movements suggest that nystagmus induced by hyperventilation is a good sign of vestibular diseasepsychogenic (psychiatric) disturbancepsychogenic (psychiatric) disturbance Must be emphasised positive hyperventilation does not rule out vestibular disorder Must be emphasised positive hyperventilation does not rule out vestibular disorder use of the Nijmegen Questionnaire use of the Nijmegen Questionnaire

19 Evidence Base “A close association between anxiety and dizziness was emphasized by Sigmund Freud in an early paper on anxiety neurosis” (Freud 1895) “A close association between anxiety and dizziness was emphasized by Sigmund Freud in an early paper on anxiety neurosis” (Freud 1895)

20 Studies: Simon et al (1998) Psychosomatic model -- a primary psychiatric disturbance causes dizziness Psychosomatic model -- a primary psychiatric disturbance causes dizziness hyperventilation and hyper arousal increased vestibular sensitivity hyperventilation and hyper arousal increased vestibular sensitivity Somato-psychic model -- a primary inner ear disturbance causes anxiety, signals from the inner ear are misinterpreted as signifying immediate danger, which increases anxiety. Increased anxiety increases misinterpretation. Conditioning makes it persistent Somato-psychic model -- a primary inner ear disturbance causes anxiety, signals from the inner ear are misinterpreted as signifying immediate danger, which increases anxiety. Increased anxiety increases misinterpretation. Conditioning makes it persistent The chicken or the egg, difficult to know which The chicken or the egg, difficult to know which

21 Studies cont…… Staab and colleagues (2003) Laryngoscope. 2003; 113:1714-8 Staab and colleagues (2003) Laryngoscope. 2003; 113:1714-8 345 men and women age 15 to 89 (average age 43.5) dizziness for three months or longer due to unknown causes. “All but six patients were diagnosed as having psychiatric or neurologic conditions, including anxiety disorders, migraine, traumatic brain injury and neurally mediated dysautonomias” 345 men and women age 15 to 89 (average age 43.5) dizziness for three months or longer due to unknown causes. “All but six patients were diagnosed as having psychiatric or neurologic conditions, including anxiety disorders, migraine, traumatic brain injury and neurally mediated dysautonomias” Anxiety disorders were associated with 60 percent of the chronic dizziness cases Anxiety disorders were associated with 60 percent of the chronic dizziness cases 33 percent of the subjects with psychogenic dizziness had a primary psychiatric diagnosis 33 percent of the subjects with psychogenic dizziness had a primary psychiatric diagnosis

22 Staab et al. 2003 3 patterns emerged; Anxiety disorders can be sole cause of dizziness Anxiety disorders can be sole cause of dizziness Neurotologic condition can trigger the development of anxiety and phobic behaviours A neurotologic condition was responsible for the onset of dizziness but also exacerbated pre-existing or anxiety symptoms N.B; Depression was considerably less common than anxiety and was never a primary cause of dizziness
