“…Visual and idiothetic cues (vestibular, proprioceptive and efferent motor commands) are the root of spatial processing. More than a dependence on a particular sensory modality, we propose that HTA subjects, like subjects with symptoms of panic and agoraphobia [7], have a strong dependence on a particular reference frame in which the sensory information are interpreted and in which the subject would remained anchored [13]. However, in the present experiment, the relationship between the integration of sensory information in conflict conditions and the demonstrated difficulty in constructing a coherent representation of space from memory must still be clarified.…”

“…The poor performance of HTA subjects in the map drawing task could, therefore, represent a deficit in this type of representation. Indeed, the results of a previous study exhibited a preference for the use of an egocentric strategy in high anxious subjects for orientation in space [13]. This strategy could be linked to the difficulty that our HTA subjects, as well as panic agoraphobic patients [7], had in creating a map-like spatial representation.…”

Multisensory integration for spatial orientation in trait anxiety subjects: absence of visual dependence

Studies suggest a greater reliance on visual information for maintaining balance in anxious subjects. Nevertheless, links between this supposed preferred visual processing and spatial orientation have not yet been evaluated. Two groups of subjects differing in their level of trait anxiety were formed. Equipped with a head-mounted visual display, they learned a virtual corridor using passive translation but active rotation, both with normal and with two different conflicting sensory conditions. After two visual navigation trials in the corridor, they were blindfolded and asked to reproduce the same trajectory from memory. In addition, subjects drew a map of the remembered corridor. Anxious subjects were comparable to non-anxious subjects when asked to reproduce the trajectory from memory, but exhibited a deficit when drawing a map of the corridor they were in. The results do not support the hypothesis that anxious subjects use preferentially one type of sensory cue over another for spatial orientation, but instead manifest difficulties in constructing more global representations of space.

“…This domain has greatly contributed to documenting the distinction between the "what" and "where" components of spatial cognition, and to enhancing our knowledge of their cerebral counterparts (e.g., Landau & Jackendoff, 1993). Last, highly relevant information is available from the study of psychopathological syndromes related to space, such as spatial anxiety and agoraphobia (e.g., Capps & Ochs, 1995;Viaud-Delmon, Siegler, Israel, Jouvent, & Berthoz, 2000).…”

Twenty outpatients who fulfilled the criteria for a diagnosis of schizophrenia and 28 control participants were invited to learn a route through a complex outdoor environment. They were then tested in tasks intended to explore various aspects of their memorized representation of the navigational episode. Compared to controls, the patients showed significant impairment in both the verbal production of route directions and the drawing of sketch maps. They referred to fewer landmarks and provided fewer directional instructions than the controls, while making a greater number of irrelevant comments. When invited to distinguish between photographs showing views of landmarks encountered along the route and distractors, they performed as well as the controls, and they had similar response times. However, when they were presented with pairs of actual photographs taken along the route, they displayed special difficulty in deciding which of the two landmarks was encountered first along the route. This difficulty in retrieving the sequential structure of the navigational episode suggests that the patients' memories were not accurately linked to one another in their mental representation of the route. These findings are interpreted in the context of current hypotheses about the hippocampal impairment that affects schizophrenic patients.

“…Indicators of vestibular/ balance dysfunction include unilateral hypofunction on the caloric test, to identify peripheral vestibular lesions, rotational testing as an indicator of ongoing vestibular imbalance, and increased sway on computerised dynamic posturography, to identify abnormal balance control. Anxiety or arousal increases the gain of the vestibulo-ocular reflex, 35 36 changes the direction of the beating field of nystagmus 37 and induces a postural ''stiffening up'' response. 18 38 39 Therefore, vestibular test results might be affected by anxiety responses to the testing itself.…”

Objective Previous research suggested that panic disorder with agoraphobia is associated with abnormalities on vestibular and balance function tests. The purpose of this study was to further examine psychiatric correlates of vestibular/balance dysfunction in patients with anxiety disorders and the specific nature of the correlated vestibular abnormalities. The psychiatric variables considered included anxiety disorder versus normal control status, panic disorder versus non-panic anxiety disorder diagnosis, presence or absence of comorbid fear of heights, and degree of space and motion discomfort (SMD). The role of anxiety responses to vestibular testing was also re-examined. Methods 104 subjects were recruited: 29 psychiatrically normal individuals and 75 psychiatric patients with anxiety disorders. Anxiety patients were assigned to four subgroups depending on whether or not they had panic disorder and comorbid fear of heights. SMD and anxiety responses were measured by questionnaires. Subjects were examined for abnormal unilateral vestibular hypofunction on caloric testing indicative of peripheral vestibular dysfunction, asymmetric responses on rotational testing as an indicator of an ongoing vestibular imbalance and balance function using Equitest dynamic posturography as an indicator of balance control. Logistic regression was used to establish the association between the psychiatric variables and vestibular or balance test abnormalities. Results Rotational test results were not significantly related to any of the psychiatric variables. The presence of either panic attacks or fear of heights increased the probability of having caloric hypofunction in a non-additive fashion. SMD and anxiety responses were independently associated with abnormal balance. Among specific posturography conditions, the association with SMD was significant for a condition that involved the balance platform tilting codirectionally with body sway, suggesting an abnormal dependence on somatosensory cues in the control of balance. Conclusion In patients with anxiety disorders, higher SMD is indicative of somatosensory dependence in the control of balance. The absence of both panic and fear of heights reduces the probability of having peripheral vestibular dysfunction. Future research should examine if vestibular rehabilitation can be of value for patients with anxiety disorders complicated by SMD.
