(1) immunomodulatory therapy for the underlying immune disorder, often with high dose
intravenous (IV) steroids which speeds recovery, and
(2) management of symptoms through supportive measures and amelioration of risk factors
associated with precipitating acute exacerbations such as infection through aggressive use
of antibiotics. Treatment of fever with antipyretics also key as even small increases in
temperature can significantly affect conduction through partially demyelinated fibers.

(1) do not have increased risk for clinically significant ICH,
(2) have early clinical improvement similar to younger patients, and
(3) have poor outcomes related to increased mortality (odds ratio 30% versus 12%), rather than
to higher rates of functional dependence (i.e. Modified Rankin Score 3 to 5).

Contraindications to performing lumbar puncture (LP):
- INR > 1.4 or other coagulopathy
- Platelets < 50
- Infection at desired puncture site
- Obstructive / non-communicating hydrocephalus
- Intracranial mass
- High intracranial pressure (ICP) / papilledema (relative contraindication depending on etiology; especially a concern with intracranial mass lesion secondary to the increased risk of transtentorial or cerebellar herniation)
- Focal neurological symptoms/signs, decreased level of consciousness
- Partial / complete spinal block
- Acute spinal trauma
