Suicidal ideation in a European Huntington's disease population
BACKGROUND: Previous studies indicate increased prevalences of suicidal ideation,
suicide attempts, and completed suicide in Huntington's disease (HD) compared
with the general population. This study investigates correlates and predictors of
suicidal ideation in HD.
METHODS: The study cohort consisted of 2106 HD mutation carriers, all
participating in the REGISTRY study of the European Huntington's Disease Network.
Of the 1937 participants without suicidal ideation at baseline, 945 had one or
more follow-up measurements. Participants were assessed for suicidal ideation by
the behavioural subscale of the Unified Huntington's Disease Rating Scale
(UHDRS). Correlates of suicidal ideation were analyzed using logistic regression
analysis and predictors were analyzed using Cox regression analysis.
RESULTS: At baseline, 169 (8.0%) mutation carriers endorsed suicidal ideation.
Disease duration (odds ratio [OR]=0.96; 95% confidence interval [CI]: 0.9-1.0),
anxiety (OR=2.14; 95%CI: 1.4-3.3), aggression (OR=2.41; 95%CI: 1.5-3.8), a
previous suicide attempt (OR=3.95; 95%CI: 2.4-6.6), and a depressed mood
(OR=13.71; 95%CI: 6.7-28.0) were independently correlated to suicidal ideation at
baseline. The 4-year cumulative incidence of suicidal ideation was 9.9%.
Longitudinally, the presence of a depressed mood (hazard ratio [HR]=2.05; 95%CI:
1.1-4.0) and use of benzodiazepines (HR=2.44; 95%CI: 1.2-5.0) at baseline were
independent predictors of incident suicidal ideation, whereas a previous suicide
attempt was not predictive.
LIMITATIONS: As suicidal ideation was assessed by only one item, and participants
were a selection of all HD mutation carriers, the prevalence of suicidal ideation
was likely underestimated.
CONCLUSIONS: Suicidal ideation in HD frequently occurs. Assessment of suicidal
ideation is a priority in mutation carriers with a depressed mood and in those
using benzodiazepines
