What is your diagnostic approach to patients referred for central sleep apnea on PSG but normal overnight EEG and MRI?
In lab titration study, starting with CPAP (first-line treatment, can work in many cases). If remains, BiPAP-S titration is next (usually same night) with minimum EPAP titrated to prevent apneas and IPAP to prevent hypopneas but care as to avoid too much pressure support and over ventilation. Failur...
What baseline visual testing, if any, do you recommend at diagnosis for patients with multiple sclerosis who deny visual complaints?
I do a baseline eye exam with visual acuity, OCT RNFL, and fundus photos yearly. If I see any abnormalities, then I might consider a repeat exam in six months. If all is normal and there's no history of optic neuritis, I do yearly appointments. If they are on DMTs that have eye side effects, then I ...
What is the first line therapy for demyelinating neuropathy with positive NF-155 antibodies?
Neurofascin-155 IgG antibody-associated neuropathy is a subtype of neuropathy with electrophysiologic features suggestive of demyelination, but distinctly different pathogenesis from classic CIDP, and also distinctly different response to treatments. Unlike CIDP where the target of the immune attack...
Do you consider DBS for Essential Tremor in patients who already underwent Focused Ultrasound Thalamotomy?
In patients with medication-refractory essential tremor, ablative thalamotomy (with focused ultrasound stereotactic surgery, or gamma knife) and deep brain stimulation (DBS) are effective methods for the management of tremor. Ablative thalamotomy with focused ultrasound uses acoustic energy for remo...
Would you use bupropion for mood disorder or substance use in an adult patient with previous childhood seizures that resolved?
The short answer is maybe, though it would not be my first choice. Bupropion is known to lower the seizure threshold, thus the basis of the question. Selection of an antidepressant depends on multiple factors including response to prior medications, side-effect profile, cost, presence of comorbid sy...
Do you ever use amantadine or modafinil to aid in the rehabilitation of patients with ischemic strokes?
No randomized controlled trials of amantadine or modafinil for the treatment of disorders of consciousness (DoC) after ischemic strokes have been completed. A retrospective study of ICU patients with DoC after ischemic stroke found that amantadine, modafinil, or a combination may be useful in improv...
How would you approach antithrombotic therapy in patients with acute ischemic infarcts and a non-occlusive intracranial thrombus?
I agree with the previous answer and can expand on a few key management nuances involving stroke size, symptom severity, and etiology. For stroke size, I typically initiate anticoagulation (heparin drip) if less than one-third of the affected territory is involved, extrapolating from tPA guidelines....
How clinically meaningful are the differences in the primary outcome between treatment and placebo groups in the CENTAUR trial?
Defining the term "clinically meaningful" proves challenging. Patients involved in the three positive and approved drug trials are unable to detect a slowdown in the progression rate. Attempts were made to gauge ALS providers' opinions regarding a meaningful change in the ALSFRS-R scale, suggesting ...
Would you offer adjuvant radiotherapy for a gross totally resected WHO grade 2 hemangiopericytoma/MFT of the brain in a patient with active multiple sclerosis?
This is a tough question to answer, as there are risks associated with either recommending post-operative radiotherapy or not. Hemangiopericytomas are rare intracranial tumors that arise from pericytes, support cells found in the wall of meningeal capillaries. They are part of a larger spectrum of m...
For patients with newly diagnosed brain metastases without a history of seizure activity, do you routinely start anti-seizure medication?
This is a common clinical question that has been repeatedly explored in meta-analyses and clinical guidelines. Consistently, there's no evidence to support primary prophylaxis for seizures in patients with brain tumors including brain metastases. In summary, the data does not support the routine use...
