When should lumbar puncture be prioritized for patients with suspected Guillain-Barre Syndrome?
There are two major reasons to do an LP in suspected GBS. One is to see if there is albuminocytologic dissociation supporting the diagnosis of GBS. LP done early in the course may be normal, so CSF does not drive early treatment decisions. It should also be noted that the IGOS study showed that a sm...
How do you convert between tetrabenazine, deutetrabenazine, or valbenazine for management of tardive dyskinesia?
I think of these medications as much more clinically similar than different, with the main differences relating to patients who are fast metabolizers. Fast metabolizers often respond well to lower doses of deutetrabenazine or valbenazine compared to tetrabenazine. When converting from one drug to an...
How do you counsel patients and caregivers about the trajectory of cognitive decline in Parkinson’s disease?
I address the subject of cognitive impairment fairly early in PD, since patients may notice mild deficits in multitasking and attention even within the first few years of diagnosis. Strategies such as making lists and breaking down individual tasks are effective in preserving independence. Worsening...
What would be your radiotherapy plan for a patient with recurrent GBM (WHO grade 4, IDH wild-type) s/p 2 prior resections with no prior radiation?
The scenario described in this clinical case is not uncommon. I have had patients who either live several hours away from our center or were unwilling to receive the Stupp protocol of 60 Gy in 6 weeks and were successfully treated with 3 weeks of hypofractionated RT (HFRT). HFRT over 1–3 weeks (25 G...
How would you empirically manage a large sellar/suprasellar mass with encasement of the right cavernous and terminal internal carotid arteries?
Knowing the histology of the mass would really help in creating more accurate treatment recommendations. A biopsy of a sellar mass is usually accomplished by an endonasal-endoscopic transsphenoidal approach utilizing the expertise of an ENT surgeon and a skull-base neurosurgeon. However, in this cas...
For a patient with glioblastoma also found to have a distant presumed meningioma with a location/size such that you would have otherwise recommended RT, would you offer concurrent treatment?
I think if the situation is non-urgent and the lesion (meningioma) can be safely monitored, one approach would be to prioritize treatment of the glioblastoma while observing the meningioma. If, however, the meningioma demonstrates interval growth and/or is located in an area at higher risk for causi...
How would you manage a rare presentation of an older adult after gross total resection of an "infant-type hemispheric glioma" of the left frontal lobe, IDH1 negative and negative for MYB fusions?
Infant-type hemispheric gliomas (IHGs) are rare high-grade astrocytic tumors characterized by giant size and abundant vascularity, often with regions of cystic transformation. They are aggressive brain tumors that occur during early infancy, usually between 0 and 12 months of age. They are often ver...
How do you determine the timeline for healing after craniotomy prior to starting chemotherapy and radiation?
I typically wait at least 10-14 days post-op, always after neurosurgery has re-evaluated the craniotomy site for appropriate healing and has already removed staples or sutures.
What clinical features prompt genetic testing for patients with progressive cerebellar ataxia?
In general, any patient who presents with a chronic progressive cerebellar ataxia and is </=21 years of age deserves genetic testing. If a subacute presentation arises with no clear metabolic, inflammatory, neoplastic, vascular, etc., etiology, I would also recommend genetic testing in this group.Wi...
Would you consider off-label IV thrombolysis in patients taking a DOAC and presenting with disabling acute ischemic stroke within the window?
I usually do not (since there is still equipoise) unless they are not an acute trial or thrombectomy candidate and have severe disabling deficits, and only if their last DOAC dose was not within 24 hours rather than 48 hours. I also discuss in detail the unknown and the risks with patients or their ...
