We assessed quality of life (QoL) and psychological well-being in patients with amyotrophic lateral sclerosis-induced locked-in state and their next of kin in a fully unbiased manner using eye-tracking computer systems. Eleven of 30 screened patients and 9 next of kin completed study procedures. Patients reported good QoL, which appeared to be at the cost of the QoL of their next of kin. Next of kin rated their own or patients' QoL similarly, but they identified different areas as important as compared with patients. Our results are of importance for the discussion of end-of-life decisions and the evaluation of patients' presumed wishes as well as for psychosocial interventions. Ann Neurol 2017;81:310-315.
Restrictions in communicative abilities are well known in patients with amyotrophic lateral sclerosis (ALS), but only few approaches in terms of evaluation of supportive technologies have been made. We aimed to assess the use and perceived usability of eye-tracking computer devices (ETCS) of severely impacted patients with ALS in an independent, direct manner and relate it to psychological well-being. ETCS enable active communication and social participation in the quadriplegic and anarthric disease state. Therefore, ETCS-based versions of widely used psychosocial questionnaires (ADI-12, SeiQoL-DW, WHO-5) as well as structured questions on communicative functioning and ETCS usage were developed to assess ALS patients, their next of kin and professional caregivers. Eleven patients (ALSFRS-R: 5.3 ± 5.9; ALS duration: 6.5 ± 3.8 years, range 1‒12; 82% invasively ventilated), nine next of kin and 10 professional caregivers could be assessed. Patients reported a mean use of their personal ETCS of 9.1 h per d (range 0.5‒16), with a high user satisfaction, preservation of communicative abilities and subjective indispensability of the ETCS. ETCS use was associated with higher psychological well-being. Next of kin and professional caregivers also nominated some critical aspect, which remains to be clarified. Our results strengthen the evidence that preserved mental autonomy influences psychological well-being in ALS and might even modify disease course and end-of-life-decisions in ALS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
