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 on how to take abortive migraine medications during the prodrome period?
I do not routinely counsel patients to take abortive treatments during prodrome. It would depend on headache frequency. It would be hard if their headache frequency is high, such as >8-10 headache days per month, as they may run out of their abortive treatment. If they have low headache frequency 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...
How do you treat depression symptoms in patients with Parkinson's disease?
The management of PD-related depression can be a little complicated, but there are several proposed algorithms out there based on varying degrees of evidence. Personally, I like this reference (Pontone and Mills, PMID 33648830) as a place to start. It makes 3 key points: Distinguishing between PD an...
Is Migraine with Unilateral Motor Symptoms (MUMS) a diagnostic entity worth considering in patients with migraine and other associated symptoms?
I do not think so. It is not a part of the ICHD-3 criteria. If a patient with migraine disorder presents with weakness, it is possible that the weakness/motor symptoms are symptoms of migraine disorder. There is a diagnostic classification for such a patient already in the ICHD-3 criteria, which wou...
Do any subgroups of headache patients benefit more from neuromodulation devices compared to pharmacologic treatment?
I think patients with episodic cluster headache benefit greatly from external vagus nerve stimulation (gammaCore) use. This device aborts cluster attacks and has a preventative action as well for future attacks during a cluster bout. It allows for more than 2 treatments per day if the patient is hav...
What treatment do you use for stroke prevention in cervical artery dissection?
Two prior RCTs (CADISS and TREAT-CAD) investigated this topic, each with distinct designs. The CADISS trial found no statistically significant difference in primary outcomes between antiplatelet and anticoagulation therapy for extra-cranial dissection. However, the TREAT-CAD trial failed to demon...
How do you approach evaluation of a patient referred for mononeuritis multiplex and +SSB?
Step 1: A clinical syndrome of mononeuropathy multiplex always requires an EMG study. Is the primary mechanism of the MnM axonal or demyelinating? If it is demyelinating, there are only two possible diagnoses: multifocal CIDP (Lewis Sumner syndrome, which can occur in the context of Sjogren's syndro...
What is your approach to secondary stroke prevention in patients with atrial fibrillation and intracranial stenosis (>70%)?
The patient clearly needs to be on an anticoagulant for stroke prevention with atrial fibrillation and I would choose apixaban. If an antiplatelet is added to the apixaban, the risk of a major bleeding side effect is significantly increased. It is uncertain if apixaban is effective in reducing the r...
When should you seek hyperbaric oxygen therapy for patients with CRAO?
I usually pursue hyperbaric oxygen therapy within the 24-hour window from symptom onset for CRAO. This can be performed following TNK if given. In reality, though, there are multiple barriers to achieving this, including: Few centers offer hyperbaric oxygen therapy Labor intensive Difficulty with i...
