How do you interpret conflicting findings on CSF immunoglobulin tests for work up of multiple sclerosis and its mimics?
Although the specific role of cerebrospinal fluid (CSF) testing has evolved in the successive revisions of the McDonald criteria, it remains an important part of the evaluation of suspected multiple sclerosis (MS), both to provide support for the diagnosis of MS and to look for findings that suggest...
When would you consider prescribing a wakefulness promoting agent for excessive daytime sleepiness from insufficient sleep?
I would never consider prescribing an alerting medication for someone with insufficient sleep. Behaviorally insufficient sleep is a diagnosis in and of itself. The treatment for excessive daytime sleepiness in the case of insufficient sleep is changing behavior to allow for more time in bed. I would...
How effective have you found acupuncture for treatment of chronic migraine?
I would prefer to educate a patient interested in acupuncture for severe headaches about all the other treatments that are available. However, if they would still like to pursue acupuncture, I would support them, just like Dr. @Dr. First Last would say. Some patients can get better, although it is n...
How do you balance the risk of unnecessary treatment with acyclovir against the risk of delaying treatment in encephalitis cases where CSF pleocytosis is absent?
Treatment with IV acyclovir should start as soon as the diagnosis of Herpes simplex encephalitis is considered. Since the question states that CSF pleocytosis is absent, then CSF has been obtained. PCR for HSV should be obtained on that CSF. Early in my career, when acyclovir was investigational and...
In a patient with strong serologic evidence of SLE presenting with isolated bilateral lower limb sensorimotor neuropathy, normal neuroimaging, and CSF, would you initiate cyclophosphamide with pulse-dose steroids upfront, or reserve escalation (e.g., plasma exchange or immunosuppressants) for cases refractory to steroids?
This has been a dilemma for me for over several decades.1. There is no good large data to guide us on this question. I do not think there is one correct answer.2. All sensorimotor neuropathies are not created equally. I assume all other causes of sensorimotor polyneuropathy have been ruled out. Howe...
When do you consider using a paramedian approach for a lumbar puncture?
I consider the paramedian approach for lumbar puncture in several clinical scenarios: When patients are unable to adequately flex their spine. When midline interspaces are narrow (<1 cm). When ultrasound reveals densely calcified spinal ligaments—a common finding in elderly patients that can obscure...
What is your approach to the management of persistent encephalopathy following ischemic injury to bilateral thalami?
This is a challenging case to manage and can be resistant to interventions. I am assuming when you say encephalopathy, you are meaning disorders of consciousness (DoC), in which the patient is comatose or somnolent. In those cases, generally speaking, we will start dopaminergic medications, usually ...
What are some alternatives to dexamethasone for brain edema in patients who are allergic, have an intolerance, or refuse the medication?
Dexamethasone is one of the most frequently prescribed medications in neuro-oncology clinics. Dexamethasone is often favored over other corticosteroids owing to its lower mineralocorticoid effects and high potency as well as essentially 1:1 oral to IV ratio meaning that we use similar IV and oral do...
What is your treatment approach for MAG antibody associated polyneuropathy?
When patients have a classic Distal acquired demyelinating sensory (DADS) Neuropathy phenotype (by clinical +/- EDX criteria), typically an SPEP/IFE is checked first, and if an IgM monoclonal gammopathy is observed, then I typically check MAG antibodies at that point (if clinical and EDX features ar...
Do you often encounter compressive neuropathies such as carpal tunnel syndrome in patients with spastic cerebral palsy?
The issue of movement disorders and spasticity, in particular, is very problematic in people with cerebral palsy. I think, unfortunately, what often happens as these patients grow into adults, is that conditions like compressive neuropathies are simply not thought about. As people with cerebral pals...
