“…Keeping in mind the high prevalence and socio-economic impact of dementia compared with ALS, we expected such a difference regarding the number of publications. Second, the thematic focus of the publications we retrieved was notable: of the 41 references we included in our spectrum of ethical issues, only 5 publications dealt with a broad range of ethical issues in ALS [2,6,7,17,18] while 13 publications concentrated on end-of-life decision making and palliative care [10,12,14,15,[19][20][21][22][23][24][25][26][27]. Of these 13 publications, some explicitly dealt with end-of-life decision making or palliative care in ALS [15,21,24], while others used ALS only as an example (many times in form of a case report) to highlight general aspects of these issues [10,19,22].…”
