Quality of life, depression and anxiety in cerebral amyloid angiopathy: A cross-sectional study.

BACKGROUND AND PURPOSE

Data on health-related quality of life (HRQoL) and mood in cerebral amyloid angiopathy (CAA), a disease characterized by stroke and cognitive decline, are limited. We aimed to investigate the impacted domains of life, value-based HRQoL and the prevalence of depression and anxiety in patients with CAA.

METHODS

We conducted a cross-sectional study of patients with sporadic (s)CAA, lobar dominant mixed CAA and hypertensive arteriopathy (mixed CAA-HTA), or Dutch-type hereditary (D-)CAA, from prospective outpatient clinic cohorts. Participants completed four questionnaires: the EuroQoL 5 dimensions 5-level questionnaire (EQ-5D-5L; EQ-VAS for visual analogue scale; EQ-Index for index rating), the Short-Form 36 questionnaire (SF-36), the Center for Epidemiologic Studies-Depression scale (CES-D), and the Hospital Anxiety and Depression Scale (HADS; -D for depression and -A for anxiety subscales). The EQ-5D-5L assesses the domains mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The SF-36 domains are physical functioning, social functioning, physical role limitations, emotional role limitations, mental health, vitality, bodily pain, and general health perceptions. We compared age- and sex- adjusted HRQoL (SF-36 domain scores; EQ-VAS; EQ-Index) to the Dutch normative population, and estimated the prevalences of current depression (either: history of depression or current use of antidepressants, with high score on CES-D [≥16] and/or HADS-D [≥8]; or high score on both depression questionnaires) and anxiety (HADS-A ≥ 8).

RESULTS

We included 179 patients: 77 with sCAA (mean age: 72 years, women: 36%), 31 with mixed CAA-HTA (68 years, women: 29%), and 71 with D-CAA (56 years, women: 52%, symptomatic: 35 [49%]). The SF-36 profiles of all patient groups were similar, negatively differing from the norm in emotional role functioning, social functioning and vitality. The EQ-VAS score of patients (mean [SD] sCAA: 76 [16], D-CAA: 77 [15]) was similar to the norm, as was the EQ-Index score. Fifteen patients with sCAA (23%; 95% confidence interval [CI] 13%-33%), seven with mixed CAA-HTA (27%; 95% CI 10%-44%) and eight with D-CAA (14%; 95% CI 5%-22%) were noted as having depression. The prevalences of anxiety and depression were equivalent.

CONCLUSIONS

We found that CAA influenced emotional role functioning and aspects linked to social engagement consistently across its subtypes. One quarter of patients exhibited depressive or anxiety symptoms. Recognizing these impacted domains could enhance overall well-being.
