Recovery

A spontaneous recovery of the clinical condition on the basis of reabsorption of oedema in the central nervous system may be expected in the relapsing-remitting type of multiple sclerosis. The inflammation process during an MS exacerbation is accompanied by the formation of oedema, which hinders the passage of information through the central nervous system and leads to an outburst of symptoms (a relapse). After some time (days-weeks), the oedema is reabsorbed and the obstruction in the central nervous system reduced (remission), clinically manifested by a recovery of symptoms. Studies using magnetic resonance imaging (MRI) however, have indicated that there has not always been a clear relation between lesions of the central nervous system seen on MRI and clinical manifestation of symptoms (Kidd et al, 1998).
