Headache Characteristics Among Patients With Epilepsy And The Association With Temporal Encephaloceles, Patricia Graese, Milad Yazdani, Zeke Campbell

Department of Neurology Faculty Papers

PURPOSE: Our aim was to determine if headaches characteristic of possible Idiopathic Intracranial Hypertension (IIH) and in general were more prevalent in patients with versus without temporal encephaloceles (TEs) among patients with epilepsy.

METHODS: Electronic medical records were reviewed retrospectively. Among 474 patients with epilepsy, 103 patients (21.7%) had at least one TE diagnosed on initial MRI or on retrospective review by a board-certified neuroradiologist, while 371 patients had no TE present. The patients were grouped into one of four categories depending on their headache characteristics (IIH-like, peri-ictal, other, or no headaches). Analysis of the categories was performed using a …

Parenteral Nsaids For Acute Treatment Of Migraine: Adherence To The Ihs Guidelines For Controlled Trials, John G. Curran, John Waters, Hsiangkuo Yuan

Department of Neurology Faculty Papers

Background: Parenteral non-steroidal anti-inflammatory drugs (NSAIDs) are important alternatives to oral NSAIDs, especially in patients with severe migraine who have emesis or gastroparesis. With increasing research on using parenteral NSAIDs for acute migraine, it is critical to examine the quality of these studies. Our goal was to assess the adherence of these trials to the International Headache Society (IHS) controlled trial guidelines for acute treatment of migraine. Methods: We queried PubMed for clinical trials investigating parenteral NSAIDs for acute treatment of migraine in adult patients. We developed a 14-point scoring system based on the essential components of the IHS guidelines. …

The Role Of Adenosine Signaling In Headache: A Review., Nathan T. Fried, Melanie B. Elliott, Michael L. Oshinsky

Department of Neurology Faculty Papers

Migraine is the third most prevalent disease on the planet, yet our understanding of its mechanisms and pathophysiology is surprisingly incomplete. Recent studies have built upon decades of evidence that adenosine, a purine nucleoside that can act as a neuromodulator, is involved in pain transmission and sensitization. Clinical evidence and rodent studies have suggested that adenosine signaling also plays a critical role in migraine headache. This is further supported by the widespread use of caffeine, an adenosine receptor antagonist, in several headache treatments. In this review, we highlight evidence that supports the involvement of adenosine signaling in different forms of …

Acetate Causes Alcohol Hangover Headache In Rats., Christina R Maxwell, Rebecca Jay Spangenberg, Jan B Hoek, Stephen D Silberstein, Michael L Oshinsky

Department of Neurology Faculty Papers

BACKGROUND: The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

METHODS: We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

RESULTS: Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

Hemicrania Continua-Like Headache Associated With Carotid Dissection May Respond To Indomethacin, Avi Ashkenazi, Muhammad A. Abbas, Dinesh K. Sharma, Stephen D. Silberstein

Department of Neurology Faculty Papers

Hemicrania continua (HC) is an idiopathic, chronic disorder characterized by a continuous, strictly unilateral headache associated with ipsilateral cranial autonomic symptoms. The symptoms of HC typically respond dramatically to indomethacin therapy. We describe a patient with traumatic internal carotid artery (ICA) dissection, who presented with a clinical picture mimicking HC that initially responded to indomethacin. Patients with a clinical picture similar to HC should be managed with a high index of suspicion for a possible cervical arterial dissection.

Botulinum Toxin And Other New Approaches To Migraine Therapy, Avi Ashkenazi, Stephen Silberstein

Department of Neurology Faculty Papers

The number of migraine treatments and our understanding of migraine pathophysiology are both increasing. Newer treatments are focusing on migraine prevention. Botulinum toxin (BTX) is a potent neurotoxin that has been used primarily for diseases associated with increased muscle activity. Recently the toxin was found to have antinociceptive effects that are probably independent of its muscle-relaxant action. Recent clinical trials support the efficacy of BTX type-A (and possibly also type-B) in the treatment of migraine. The anticonvulsant topiramate was recently shown to be effective for migraine prevention. With the low doses used for this indication, cognitive side effects are less …
