"I've been wanting to go home for awhile," Isaac LeBlanc says as he grins at his big understatement.

LeBlanc, a 27-year-old Comox Valley resident, has been in hospital care for well over a year, after he started suffering from neck pain in late 2011.

His condition quickly worsened and within a matter of weeks he was unable to speak or move his body from the neck down...

Various papers discuss this condition. For example:

Acute multiple sclerosis (marburg type) is associated with developmentally immature myelin basic protein

Abstract

We have studied a case of acute, fulminating multiple sclerosis (MS) (Marburg type) at the pathological and biochemical levels. Postmortem examination of the brain revealed extensive areas of gross rarefaction in the hemispheric white matter. Histologically, well-demarcated areas of demyelination with a large influx of macrophages and a subtle perivascular infiltration of lymphocytes were seen with relative preservation of the axis cylinders. Myelin basic protein (MBP) was isolated and purifed from noninvolved white matter. It was slightly larger in molecular weight than MBP from normal brain or from chronic MS brain. The increase in mass was accounted for, in part, by the deimination of 18 of 19 arginyl residues to citrulline, making the patient's MBP much less cationic than MBP from normal white matter. When expressed as the ratio of least cationic form of MBP to the most cationic (C-8/C-1), the normal ratio was 0.82, chronic MS 2.5, and the patient in this study 6.7. Because the ratio of 6.7 was similar to 7.5 found for a 15-month-old infant, MBP was considered to be of the immature form. The data are consistent with a genetic factor influencing the charge microheterogeneity of MBP. The resulting less cationic MBP cannot carry out its normal function of compacting multilayers.

As above papers suggests, this rare neurological condition is not related to Marburg haemorrhagic fever, caused by infection with a Filovirus.
