Receiving Long‐Term Disability or Pursuing a Legal Claim May Prevent Recovery From Chronic Dizziness

Objectives/Hypothesis

Chronic dizziness (CD) and imbalance have multiple etiologies. CD is strongly linked with psychiatric and psychological comorbidities, thus an interdisciplinary approach, including psychopharmacological interventions, is recommended. Despite the use of this comprehensive treatment approach, the recovery of individuals with CD that pursue long-term disability (LTD) insurance or legal claims (LC) appears hampered. As such, we aimed to compare symptom recovery from CD in an interdisciplinary setting between patients receiving LTD/LC versus those who were not, and to explore the factors that may contribute to changes in symptom severity.

Study Design

Retrospective cohort study.

Methods

Dizziness-related diagnoses were extracted from the charts of 195 adults in an outpatient interdisciplinary neurotology clinic in Toronto, Canada. Patients with baseline Dizziness Handicap Inventory (DHI) and Dizziness Catastrophizing Scale (DCS) assessments between August 2012 and July 2018 and a mean follow-up visit within approximately 10 months were included. The study participants were categorized as "LTD/LC+" (n = 92) or "LTD/LC−" (n = 103), referring to either receiving or pursuing LTD/LC or not, respectively.

Results

There were differences in the mean percentage changes in DHI (t[187] = 3.02, P = .003) and DCS (t[179] = 2.63, P = .009) scores between LTD/LC+ and LTD/LC− patients. LTD/LC+ patients showed 8.0% and 7.6% mean increases in DHI and DCS scores, respectively, whereas LTD/LC− patients showed 21.5% and 25.9% reductions in DHI and DCS scores, respectively, controlling for age, sex, and baseline illness severity.

Conclusions

Patients receiving or pursuing LTD insurance or a legal claim did not improve from CD and dizziness catastrophizing compared to those who were not. Future studies are required to test these findings prospectively and to determine the factors that may contribute to symptom recovery, including the anxiety-aggravating effects of the LTD/LC process and the deleterious consequences of developing a sick-role while afflicted with a chronic illness.
