Full Study Summary:

Since April 2010 a quarterly follow-up is available for patients with ALS at Geneva University Hospitals. It takes place in the outpatient unit of the Department of Neurology, and includes interventions by the multidisciplinary team of the " Center for Amyotrophic Lateral Sclerosis and related diseases ". This new tracking method can help improving quality of life of patients and their families by adapting medical care, proposing communication aids, facilitating access to specialized examinations and anticipating pulmonary, nutritional and neurologic complications. Moreover, it speeds up administrative procedures, improves the flow of information between medical teams inside and outside the hospital and it allows and encourages discussion about advanced directives.

Since June 2012, the multidisciplinary follow-up is monitored through a Cohort study that was approved by the ethical committee (NAC 11-062R). We collect clinical examination findings, anthropometric evaluation, blood analyses, pulmonary function tests, respiratory muscle strength, arterial blood gases, nocturnal oximetry, and evaluation by occupational therapists and by physiotherapists on a quarterly basis. Nerve conduction studies are done at the beginning of the follow-up to identify the degree and extent of loss of upper and lower motoneurons in ALS and to help guiding the diagnosis. MRI and analysis of cerebrospinal fluid are also acquired at the beginning of the follow-up in order to rule out other diagnoses which can mimic ALS. Definite, probable or possible ALS is defined according to the Revised El Escorial and Awaji criteria [16-17]. Patients are referred to a genetic counselor who helps making informed decisions regarding genetic issues. The data collected are inserted into the Secu-Trial database, which is managed by an assistant provided by the Clinical Research Center.
