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...
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...
At what lab values (ferritin, TSAT%) would you offer IV iron therapy to patients with restless leg syndrome?
1. I am hopeful that practitioners will start understanding that ferritin alone is not enough to assess iron because of its acute phase reactivity. I like to order iron parameters after a 5-9 hour fast so the serum iron is not speciously elevated and get a ferritin and TSAT. If the ferritin is <30 a...
How do you utilize Diamox in patients with cerebral venous sinus thrombosis and vision symptoms who do not undergo thrombectomy/recanalization?
Diamox (acetazolamide) is often used to treat papilledema with associated visual loss in cases of CVST. While there is a theoretical risk of dehydration from acetazolamide with potential worsening of the thrombosis, 1) acetazolamide is a weak diuretic and 2) the risk of blinding visual loss usually ...
How do you decide between the different oral longer acting levodopa medications?
The question would be, why are you changing, and what are you changing from? (i.e., are one of these your initial agent, a change due to Sinemet side effects, or a change because of motor fluctuations?) The current theory on dopamine replacement is "smoother is better," so the longer (and lower) you...
How do you manage patients with chronic migraine as well as medication overuse headaches?
I agree with Dr. @Dr. First Last about the treatment for chronic migraine and MOH for patients on opiates and/or barbiturates. If they are taking frequent opiates, I prefer to have a pain management doctor detoxify them. In the past, I slowly decreased their medication while giving them long-acting ...
How would you determine the safety of anticoagulation in patients with evidence of cerebral microhemorrhages who present with acute stroke secondary to cardioembolism?
This question assumes that the patient already had an MRI showing microhemorrhages. The Boston criteria provide guidelines for the number of microbleeds, associated superficial siderosis, or major hemorrhage to make the diagnosis of cerebral amyloid angiopathy. I would also assume that at least some...
For a patient with acute stroke who cannot tolerate statins, what is your preferred second-line agent for secondary prevention?
First question - is the patient experiencing the nocebo effect? I would explore statin-based symptoms. Ezetimibe - if only needs a small reduction. If you need to be more aggressive, I would use PCSK9 inhibitors. If the patient cannot tolerate a PCSK9 inhibitor or if you need more lowering, you can ...
