Idiopathic inflammatory demyelinating disorders of the central nervous system (IIDCDs) represent a broad spectrum of disorders whose varied clinical profile has important implications for diagnosis, management and identifying grey areas in categorization.
To study clinical, imaging & laboratory profile of IIDCDs pts. and categorize them into specific groups.
Retrospective case series of 81 pts. Cases effectively categorized into 4 groups: MS, NMOSDs, CIS & ADEM and their subgroups. Cases with diagnostic difficulty later sorted out into 3 groups: Atypical, crossovers & converters.
32% categorized as NMOSDs, 28.4% as MS, 25.9% as CIS & 13.6% as ADEM. Monophasic (64.2%) course and polysymptomatic presentation were most common. 23.46% had optico-spinal presentation; LETM seen in 44% cases. Aquaporin-4 positivity seen in 31.25% NMOSDs.
NMOSDs had higher relapse rate & disability, while longer duration of disease & frequent relapses seen in MS group. 30% CIS had abnormal brain MRI. Gray matter involvement commoner in MS & ADEM groups. Low Aquaporin-4 seropositivity in tested IIDCDs. No significant difference between seropositive & negative pts. in terms of relapses, cord length & disability.
Clinical features, course & severity play a dominant role in categorization. IIDCDs considered a spectrum because of common & overlapping clinical presentation.
