Diagnostic odyssey in amyotrophic lateral sclerosis: diagnostic criteria and reality

BackgroundDiagnosing a rare disease, such as amyotrophic lateral sclerosis, is a major challenge for physicians and patients. Despite detailed diagnostic criteria, this process often does not proceed as it should, exacerbating the problems of patients. In the following study, we show how the process, which in medical sciences has been called the "diagnostic odyssey", proceeds and how it affects patients.Materials and methodsParticipants were recruited via a neurology clinic. Twenty-four patients with the diagnosed disease were interviewed using in-depth interviews and an author questionnaire: 9 females and 15 males ages ranging from 30-39 to 60-69.ResultsThe median time from 1st symptoms to diagnosis was almost 12 months and mean almost 20 months (min. 3, max 106). Only 5 patients waited less than 6 months for being diagnosed. Over 80% of patients received an alternative diagnosis on the first attempt.ConclusionALS is a fast-paced fatal disease, which requires immediate action to slow down the course of the disease and improve patients' quality of life. However, in many cases, the disease is diagnosed too late. It also happens that a wrong diagnosis causes inaccurate treatment, which accelerates the development of ALS. For this reason, it is necessary to expand the clinical and communication competences of medical personnel already at the stage of medical studies. In addition, the diagnostic criteria should highlight the common problem with diagnosing ALS.
