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...
How do you counsel patients on the cognitive effects of DBS for Parkinson's disease?
Cognitive effects after DBS procedures are multifactorial. Many times, patients are affected by Parkinsonian motor manifestations, such as dyskinesia or tremor, and treating these problems successfully with DBS and subsequent medication adjustments can help substantially with cognitive performance. ...
How do you manage levodopa in a patient with Parkinson's and RLS with augmentation?
Levodopa is known to cause augmentation or worsening of restless leg syndrome (RLS) symptoms (Högl et al., PMID 19756826). There are varying reports of RLS correlation with Parkinson disease (PD) with most studies noting an association (Ondo et al., PMID 11890847; Peralta et al., PMID 19691124; Calz...
What is your approach to evaluating Tardive Dyskinesia in nonverbal patients?
Nonverbal patients can still be affected by TD, so if there is a significant functional impact, treatment can still be offered. If a patient is completely unable to communicate, it is difficult to assess for side effects or symptomatic improvement, so the risk-to-benefit analysis would be largely un...
How do you counsel patients with blepharospasm regarding driving?
I do not have a specific protocol for driving with blepharospasm, so I would advise assessing each case individually. Occupational therapy can perform standardized driving assessments for safety if there is a concern.
