Background
 Simpson : Psychogenic dizziness—a clinical syndrome characterized by vague,


persistent sensation of dizziness, subjective imbalance, lightheadedness, or
fullness in the head without evidence of vestibular dysfuntion on NE or balance
function tests.
Bath: 20~25% patients with chronic dizziness psychogenic dizziness.

Jacob: Psychogenic dizziness is significant related to panic disorder with or
without agoraphobia. Some related to hyperventilation.
Robichaud: Hyperventilation-induced nystagmus is significant related with

retrocochlear pathology than with end-organ pathology.
Murphy: Mal de Debarquement syndrome (MDDS)—an imbalance or rocking

sensation lasts for 6-12 months after prolonged exposure to motion (most
commonly after a sea cruise or a long airplane flight).
Brandt: Phobic postural vertigo (PPV)—a somatoform disorder characterized by
a chronic and subjective imbalance and short attacks of dizziness.
Panic disorder with/without agoraphobia
Diagnosis criteria for panic attacks in DSM-IV (≧4 symptoms)
Symptoms develop abruptly and reached peak in 10`mins.
1. Palpitations, pounding heart, or accelerated heart rate
2. Sweating
3. Trembling or shaking
4. Sensations of shortness of breath or smothering
5. Feeling of choking
6. Chest pain or discomfort
7. Nausea or abdominal distress
8. Feeling dizzy, unsteady, lightheaded, or faint
9. Derealization (feelings of unreality) or depersonalization (being detached from
oneself)
10. Fear of losing control or going crazy
11. Fear of dying
12. Paresthesias (numbness or tingling sensations)
13. Chills or hot flushes


Agoraphobia: Axiety about being in places or situation which escape might be
difficult.
Yardley:
 64% of dizzy patients need of psychological help. 8% had panic disorder.
 Co-morbid dizziness and anxiety is 11%.
The concept of psychogenic dizziness



Psychoanalytical view: Psychic conflicts can manifest as somatic symptoms.
 Psychogenic vertigo is often diagnosed as an anxiety concomitant, or an
anxiety equivalent.
Conflicts or stress in the life  dizziness  psychic defenses collapse  trigger
regressive mechanisms  chronic dizziness
The onset of Phobic postural vertigo (PPV) coincided with psychological
conflicts associated with the feelings of existential threat.
 Bridges, empty rooms, the crowds
 concomitant anxiety and autonomic symptoms
 personality disorder, especially obsessional traits
Revised taxonomy for vestibular disorders and for psychiatric dizziness

Dizziness is either organic or psycogenic?

Categories of dizziness etiologies:
 Syndromal vestibular disorders
 Non-syndromal vestibular disorders
 Subclinical vestibular disorders
 No vestibular disorder
“Psychiatric dizziness”, on if it is part of a recognized psychiatric symptom
complex, and cannot be explained by a vestibular disorder.

Behavioral effects on vestibular (dys)function
Psychological factors on vestibular function:
Attention, cognitive activities, mental stress, and hyperventilation
 After hyperventilation, significant increase in body sway of normal individuals.
 Hyperventilation reductions in somatosensory input
 Hyperventilation induced nystagmus in patients with vestibular disorders
 Hyperventilation affects both affected nerve and central compensation.
 Caution us: Hyperventilation-induced dizziness not always psychogenic
Somatopsychic effects:
Can vestibular symptoms result in anxiety?
 Space and motion discomfort visual influence on balance Autonomic
anxiety symptoms, including sweating, dry mouth, hot flash.
Can a reduction of the symptoms/signs of vestibular dysfunction lead to a reduction in
anxiety?
 Vestibular rehabilitaion and cognitive behavior therapy can improve patients
with agoraphobia and vestibular dysfunction independently.
Treatment

Treatment of Panic Disorder with and without Agoraphobia
 Medication: anti-depressant (SSRI), anxiolytics(eg. Ativan, Xanax)
 Education about physical and mental symptoms (cognitive restructuring)
 Breathing retraining
 Interoceptive exposure (repeated hyperventilation to produce physical
symptoms); and real life (In-vivo) exposure to feared situations.
