Convexal subarachnoid hemorrhage has been associated with different diseases, reversible cerebral vasoconstriction syndrome and cerebral amyloid angiopathy being the 2 main causes. ⋯ Headache is a key symptom allowing a presumptive etiological diagnosis of convexal subarachnoid hemorrhage. While the absence of headache suggests cerebral amyloid angiopathy as the more probable cause, severe headache obliges us to rule out other etiologies, such as reversible cerebral vasoconstriction syndrome.

Response of cervicogenic headaches and occipital neuralgia to radiofrequency ablation of the C2 dorsal root ganglion and/or third occipital nerve.
This article investigates the degree and duration of pain relief from cervicogenic headaches or occipital neuralgia following treatment with radiofrequency ablation of the C2 dorsal root ganglion and/or third occipital nerves. It also addresses the procedure's complication rate and patient's willingness to repeat the procedure if severe symptoms recur. ⋯ Radiofrequency ablation of the C2 dorsal root ganglion and/or third occipital nerve can provide many months of greater than 50% pain relief in the vast majority of recipients with an expected length of symptom improvement of 5-6 months.

To examine calcitonin gene-related peptide (CGRP) gene expression under inflammatory conditions using trigeminal ganglia organ cultures as an experimental system. These cultures have increased proinflammatory signaling that may mimic neurogenic inflammation in the migraine state. ⋯ These results demonstrate that reactive oxygen species can activate proCT expression from the CGRP gene in trigeminal glia by a paracrine regulatory mechanism. We propose that this glial recruitment pathway may occur following cortical spreading depression and neurogenic inflammation to increase CGRP nociceptive actions in migraine.

Headache resulting from idiopathic intracranial hypertension (IIH) in a population of moderately to obese women of childbearing age. The causes overall remain unclear. With this review, we provide an overview of clinical treatment and management strategies. ⋯ In this review, we discuss headache associated with IIH and spontaneous intracranial hypotension. Much needs to be learned about treatment options for patients with cerebrospinal fluid leaks including methods to strengthen the dura.

Limited and conflicting data exist regarding the prevalence of psychiatric disorders, particularly substance use disorders (SUDs), among migraineurs in inpatient clinical settings. ⋯ A history of generalized anxiety disorder, high levels of current anxiety symptoms, and current alcohol dependence are the strongest psychiatric predictors of migraine status among substance-dependent inpatients. However, migraine status is not associated with SUD treatment dropout.
