Abstract
Patients with vestibular schwannoma (VS) often complain about tiredness, exhaustion, lack of energy, and strength, but such symptoms of fatigue have scarcely been objectified and analyzed in a VS population. We aimed to characterize fatigue in a cohort of patients with VS and compare such symptoms with a control group. All patients who attended an educational course for patients with VS were surveyed with validated tools for assessment of fatigue (fatigue severity scale), anxiety and depression (hospital anxiety and depression scale), sleepiness (Epworth sleepiness scale), and apathy (Starkstein apathy scale). Quality of Life was assessed with the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL). Symptom severity was estimated with a visual analog scale (VAS). The results have been compared to a control group consisting of patient companions. Data from 88 VS patients and 49 controls were analyzed. The controls had similar age and sex distribution as patients. Fifty-seven percent of VS patients had significant fatigue, compared to 25% in the control group. The mean fatigue score was 4.1 for the patients, and 2.8 for controls. Patients with fatigue were more likely to have depression, anxiety, sleepiness, and apathy. No correlation of fatigue was found with age, gender, or treatment modality. Regression analyses revealed depression, apathy, and vertigo to be predictors of fatigue. Fatigue was strongly correlated to QoL. Almost six out of ten VS patients had fatigue, significantly higher than the control group. Interest and focus on fatigue in VS patients can improve the patient's QoL.
