SCLEROSE EN PLAQUE ET GESTION DE LAPTITUDE : A PROPOS DE DEUX CAS SUIVIS AU CENTRE DEXPERTISE MEDICAL DU PERSONNEL NAVIGANT DE RABAT

Multiple sclerosis (MS) is the most common inflammatory demyelinating disease of the central nervous system, with variable manifestations, it evolves in two main forms (relapsing and remitting) with an unpredictable evolution, theprognosis may range from minimal neurological deficit to severe disability. It mainly affects the young population. Several manifestations (organic and psychological) of MS can lead to an overall decrease in flight crew performance. It includes cognitive impairment, fatigue and depression. Episodes of spasms, dysarthria, ataxia, paresthesia, diplopia and also hemiplegia can that can affect flight safety. Disease-modifying therapiescould minimize relapse rates and slow disease progression, but are not free from sometimes major side effects that can compromise flight safety. We report our experience with two cabin crew members affected by MS and fitness management. The different manifestations of MS will be discussed with an emphasis on aeromedical implications.
