Do you find onabotulinumtoxinA injections effective for the treatment of trigeminal neuralgia?
I use botulinum toxin (off-label) for two face pain conditions, one rare, i.e., trigeminal neuralgia, and one common, i.e., temporomandibular disorder (TMD). For trigeminal neuralgia, I use a tiny needle to inject very small amounts of the toxin into the affected area of the skin and, if involved in...
How do you determine when to wean patients with idiopathic intracranial hypertension off of acetazolamide?
As a neuro-ophthalmologist, my greatest concern is vision-threatening papilledema in IIH. So if there is no papilledema, that threat should be resolved for the time being, right? Not so fast. Accurate direct ophthalmoscopy has become an "optional" skill set for most neurologists. Subtle papilledema ...
When do you use seizure prophylaxis in patients on clozapine?
The topic of the use of anticonvulsants for primary prophylaxis of clozapine-induced seizures continues to be debated. The idea of prescribing anticonvulsants prophylactically for patients taking >600 mg/day of clozapine was suggested by Devinksy et al., PMID 2006003 in 1991. Clozapine-induced seizu...
Do you recommend immunomodulating treatments such as steroids or IVIG for West Nile Virus neuroinvasive disease?
In review of the literature and CDC recommendations, the outcomes when using IVIG in this setting are variable. It has been utilized in immunocompromised patients such as solid organ transplant recipients. I have not found enough evidence to support using it in a non-immunocompromised patient. The s...
When do you switch to a different DMT in multiple sclerosis patients planning for pregnancy?
There are several key differences between the reported French study and the often-used practice in the US. In the French registry, nearly 50% of patients with the diagnosis of relapsing MS (diagnosed by either Poser or early McDonald criteria) were not on DMT. While it was common in the early 1990s ...
How do you manage daytime somnolence without a clear cause?
Throw a broad net out for the evaluation because we don't know how much has a physiological component and how much is mental/emotional. At intake, I get a moderately comprehensive set of labs. Rating Scales like HAMA, HAM-D, PHQ-9, Epworth Sleepiness Scale, and a ROS (Review of Systems) are done. I...
What factors would prompt you to refer a patient for a surgical epilepsy evaluation who has not yet failed two anti-seizure medications?
This is a good question, and of course, the discussion with the patient regarding their diagnosis and treatment plan is important. There are also expert consensus guidelines that help to clarify this (Jehi et al., PMID 35842919) and that most of us would ascribe to in these cases. Specifically, when...
How do you approach the use of newer anti-seizure medications for epilepsy patients on DOACs?
Levetiracetam and valproic acid: A nested case-control study published in 2021 (Gronich et al., PMID 34287842) in patients with afib identified an increased risk of stroke/systemic embolism with levetiracetam and valproic acid. This was followed by a few retrospective studies published in 2022 and ...
What lifestyle choices are helpful in reducing the risk of or slowing cognitive decline?
Regular daily physical exercise. A healthy diet: for example, the MIND diet: low in fat and sugar, high in vegetables and fruits, and regular hydration. Be mentally active. Participate in social activities. Get adequate sleep (7-8 hours nightly). Manage stress. Limit alcohol and avoid smoking Perio...
When do you use rozanolixizumab for Musk MG?
I tend to use rozanolixizumab in a few different situations for MuSK myasthenia. The obvious one is when patients have a significant bulbar weakness that needs to be controlled ASAP. Aside from that, I may try rozanolixizumab in patients who do not respond well to prednisone, primarily to get them b...
