Abstract PDF: Purpose: It remains unclear whether primary headaches, particularly migraine, are associated with glaucoma. We investigated potential associations between primary headaches, including migraine and tension-type headache (TTH), and primary glaucoma, including open-angle glaucoma (OAG) and closed-angle glaucoma (CAG).
Methods
We used data from the Clinical Data Warehouse collected between 2008 and 2023 to investigate whether migraine and TTH influence the risk of primary glaucoma. We compared the prevalence of primary glaucoma, including OAG, CAG, other glaucoma, and total glaucoma (TG), among patients with migraine, those with TTH, and controls.
Results
This study analyzed 46,904 patients with migraine, 48,116 patients with TTH, and 455,172 controls. Controls were selected based on propensity score matching (PSM). After adjustment for covariates and PSM, the fully adjusted odds ratios (ORs) for patients with migraine were 1.83 for OAG (95% confidence interval [95% CI], 1.33–2.51; p<0.004) and 1.55 for TG (95% CI, 1.26–1.91; p<0.004) compared to controls. Furthermore, in patients with TTH, the ORs for CAG were 2.20 (95% CI, 1.40–3.47; p<0.004) compared to controls. Additionally, patients with migraine had fully adjusted ORs of 1.71 for OAG (95% CI, 1.24–2.36; p<0.004) and 1.41 for TG (95% CI, 1.15–1.73; p<0.004) compared to those with TTH.
Conclusion
Migraine is associated with primary glaucoma, particularly OAG.

Abstract PDF: Severe acute respiratory syndrome coronavirus 2 is the virus responsible for coronavirus disease 2019 (COVID-19), which caused a global pandemic and then became an endemic condition. COVID-19 infection may be associated with clinical manifestations such as respiratory symptoms and systemic diseases, including neurological disorders, notably headaches. Headaches are a common neurological symptom in individuals infected with COVID-19. Furthermore, with the transition to endemicity, COVID-19 infection-related headaches may reportedly persist in the acute phase of COVID-19 infection and in the long term after COVID-19 infection resolves. Persistent headaches after COVID-19 infection can be a significant concern for patients, potentially leading to disability. The present review discusses the clinical characteristics and potential underlying mechanisms of COVID-19 infection-related headaches.

Update on Cluster Headaches: From Genetic to Novel Therapeutic Approaches: Myun Kim, Je Kook Yu, Yoo Hwan Kim; Headache Pain Res. 2024;25(1):42-53. Published online April 22, 2024; DOI: https://doi.org/10.62087/hpr.2024.0009; Funded: Hallym University Medical Center Research Fund

Abstract PDF: Cluster headaches affect 0.1% of the population and are four times more common in males than in females. Patients with this condition present with severe unilateral head pain localized in the frontotemporal lobe, accompanied by ipsilateral lacrimation, conjunctival injection, nasal congestion, diaphoresis, miosis, and eyelid edema. Recently, the first genome-wide association study of cluster headaches was conducted with the goal of aggregating data for meta-analyses, identifying genetic risk variants, and gaining biological insights. Although little is known about the pathophysiology of cluster headaches, the trigeminovascular and trigeminal autonomic reflexes and hypothalamic pathways are involved. Among anti-calcitonin gene-related peptide monoclonal antibodies, galcanezumab has been reported to be effective in preventing episodic cluster headaches.
