Operational impact of COVID-19
- COVID-19 had a considerable impact on residency programmes within New York City due to nearly half of all residences testing positive for COVID-19 and 16.8% undergoing quarantine in the first month.
- All fellowship programmes were disrupted, converting to video-precepting while the members underwent redeployment to other functions outside headache medicine.
- Activities in all three aspects of the neurology department—clinical care, research and education—had to shift to accommodate the demands on the hospital by COVID-19.
- For example, morning reports were carried out seven days a week, were more operational focused, involved a broader cross-section of departments and utilised Zoom technology.
- Neurology residents performed a vital role in patient care during the peak of COVID-19 admissions.
Emerging clinical phenomenology of headache and COVID-19
- Cases of secondary headache disorders associated with COVID-19 have been reported, including several cases with ophthalmoparesis reported in patients with critical illnesses.
- One patient with COVID-19 reported a severe persistent cough that may have triggered an internal carotid artery dissection and another case resulted in cerebral venous thrombosis.
- Cranial neuropathies have also been reported that typically feature ophthalmoparesis to varying degrees, alongside imagery that suggests viral inflammation is present.
- COVID-19 has exposed care disparities across the region—NYC Department Of Health reported a higher incidence of COVID-19 infection but lower drug accessibility in communities of ethnic minorities.
- In particular, these regions had limited access to migraine therapies.
Headache care
- The implementation of telemedicine using ‘Epic’ and ‘Doximity’ has worked successfully and enabled patient follow-up to continue.
- Secondary headache evaluations have been challenging because patients have been hesitant to travel to the hospital due to risk of infection.
- Swab procedures are now in place when patients come to the hospital for neuroimaging, lumbar puncture or CT myelography.
- Studies demonstrate the benefits of using telemedicine in migraine management and highlight patients rate convenience highly.
- Telemedicine results in shorter average visit times, which is of particular benefit in New York where people have to travel relatively far to visit a healthcare provider.
Headache surrounding COVID-19
- Headache associated with COVID-19 can be categorised into secondary and primary.
- Secondary headache is comprised of headache attributed to systemic viral infection (ICHD-3), headache that appears later following infection and attributed to cytokine release syndrome, and headache due to other causes such as vascular, non-vascular.
- Primary headache includes migraine triggered by COVID-19 itself, or by stress ‘let-down’ or a stressful life event that could lead to post-traumatic stress disorder (PTSD, and de novo headache disorder, such as new daily persistent headache emerging due to COVID-19.
Headache therapy challenges in COVID-19
- Patients remain afraid to visit the hospital for appointments.
- Questions have arisen regarding the use of acute treatments, such as triptans, ergotamines, and gepants, that could induce hypercoagulability in patients who have had COVID-19 quite recently.
- Initial concerns were raised regarding non-steroidal anti-inflammatory drugs (NSAIDs) increasing the risk of severe COVID-19 infection, which were later confirmed as unfounded.
- The feasibility of onabotulinumtox A injections has been a problem due to the viability of office visits.
- Concerns about the use of angiotensin-converting enzyme (ACE) inhibitors /angiotensin receptor blockers (ARB) for hypertension or migraine increasing the risk of contracting COVID-19 were initially raised.
- Hypercoagulability in relation to calcitonin gene-related peptide (CGRP)-targeting monoclonal antibodies (mAbs) has been questioned but the roll-out of eptinezumab treatment for migraine disorders has been impacted.
- Those patients with status migrainosus who are taking steroids have been instructed to remain quarantined and reduce COVID-19 susceptibility.
