Parasites may lodge in brain parenchyma, subarachnoid space, ventricular system or spinal cord, causing a myriad of pathological changes that are responsible for the clinical pleomorphism of this disease. While epilepsy is the most common clinical presentation of neurocysticercosis, more than one-third of patients present with headache as the single or most important manifestation of the disease. Neurocysticercosis-related headaches have been mostly associated with intracranial hypertension related to either hydrocephalus, giant extraparenchymal cysts, or cysticercotic encephalitis. These forms of neurocysticercosis clearly represent the minority of cases. Most patients with calcified cysticerci in the brain parenchyma develop headache without the presence of any additional evidence of intracranial hypertension or focal neurological deficits. Mechanisms involved in the association between headache and parenchymal brain calcified cysticerci are elusive. A door-to-door epidemiological survey conducted in a community where cysticercosis is endemic, disclosed that 19 out of 57 (33%) migrainous individuals receiving head CT had calcified cysticercosis. In addition, a case-control study nested to a population-based cohort disclosed that lifetime headache prevalence, current headaches, intense headaches and, in particular, migrainous (but not tensiontype) headaches, were almost five times more frequent among patients with calcified neurocysticercosis than in their matched controls without neurocysticercosis. These studies provide grounds for the further evaluation of the association between headache and calcified neurocysticercosis, particularly with the aim to better understand pathogenetic mechanisms involved in its occurrence and potential therapeutic interventions. The pathogenesis of migrainous headaches related to calcified cysticerci is not completely understood. Calcifications represent the end stage of previously viable cysticerci that have been destroyed by either the host immune system or as the result of cysticidal drug therapy. Calcified cysticerci have been considered inert lesions. However, recent evidence strongly suggest that these lesions contain trapped antigenic parasitic membranes, which may be intermittently presented to the host immune system when structural changes in the calcifications related to remodeling mechanisms allow antigenic remnants to be in contact with neighboring cerebral tissues. This exposure induces inflammatory changes in the brain parenchyma with the subsequent breakdown in the blood-brain barrier, edema formation and oxidative stress resulting from liberation of nitric oxide and other free radicals. These events may be the pathogenetic substrate for the occurrence of seizures, which often take the form of breakthrough seizures, since they ensu","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43811399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report summarizes a roundtable discussion convened to analyze evidence for early onset of prevention, ascertain its clinical relevance, and provide guidance for healthcare professionals in crafting goals and treatment expectations for patients with migraine initiating preventive therapy. Methods: A virtual roundtable meeting of migraine clinicians, researchers, and patient advocates convened in October 2020. Participants reviewed and discussed data summarizing patient and healthcare professional perceptions of migraine prevention and evidence from the peer-reviewed and gray literature to develop corresponding recommendations. Summary: Evidence from clinical studies of anti-calcitonin gene-related peptide monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) and the chemodenervation agent onabotulinumtoxinA indicate that patients may experience reduction of migraine activity within 7 days of drug administration and early attainment of disease control is associated with improvements in clinically important outcomes. The roundtable of experts proposes that early onset be defined as demonstration of preventive benefits within 1 week of treatment initiation. We recommend focusing discussion with patients around “disease control” and potential benefits of early onset of prevention, so patients can set realistic preventive therapy goals and expectations.","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43629474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients often suffer from both conditions, and they are likely to be associated in a bidirectional way. However, the nature of the association remains unclear. Understanding the epidemiological aspects of the relationship between these conditions could have important clinical implications. Objective: To evaluate the prevalence of headaches in TMD patients as well as the prevalence of TMD in patients who suffer from headaches. Method: A systematic literature search was conducted using electronic databases. Studies published in English and those that used an acknowledged diagnostic criteria for TMD and headaches were included. Study quality was assessed using the Newcastle-Ottawa scale and meta-analyses were performed to generate pooled prevalence estimates. Result: Thirty-one studies met the selection criteria for the review; 16 studies evaluated the prevalence of headache in TMD patients and 15 studies evaluated the prevalence of TMD in headache patients. The included studies were of moderate-to-high quality. Meta-analyses revealed moderate-to-large heterogeneities across included studies. Pooled prevalence estimates from meta-analyses indicated similar rates of headaches in TMD patients and of TMD in headache patients (61.58%, 95% CI 45.26–76.66 and 59.42%, 95% CI 51.93–66.60, respectively). Migraines were more commonly observed in TMD patients (40.25%, 95% CI 35.37–45.23) compared to tension-type headaches (18.89%, 95% CI 12.36–26.44). The prevalence of headaches was particularly high in painful-TMD (82.80%, 95% CI 75.41–89.10). Conclusion: Despite large variance in prevalence rates across included studies, this review suggests headache and TMD frequently co-occur, particularly in the case of migraines and muscle related TMD. This association has important clinical, pathophysiological and therapeutic implications.","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45296387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He was treated with intravenous steroid therapy inducing rapid response. Conclusion: SMART syndrome is a rare complex delayed complication of brain radiation therapy, which may present as an isolated migraine with or without aura even decades after cranial radiation. Thus, a sudden intensification or relapse of a previous migraine in a patient with remote cranial radiotherapy constitutes a red flag even decades after cranial irradiation and cured or stable tumor disease on a recent brain MRI.

Background: Excruciating pain, activation of the parasympathetic nervous system, and circadian rhythmicity characterise cluster headache attacks. Results: We find the oldest descriptions of patients suffering from the disorder in case reports of the 17th and 18th centuries. Only in the 19th and early 20th centuries did physicians start hypothesizing its cause. Initially, many researchers suspected the origin of the pain in peripheral nerves or blood vessels. However, eventually, they understood that the cause of the disease lies in the brain. In 1998, Positron emission tomography studies revealed increased activity of the posterior hypothalamus, whose role remains incompletely understood. Only recently have researchers realised that being diseased implies more than dysfunction. Recent studies analysed the consequences of cluster headache for each patient. Many struggle to deal with the disorder even in the absence of pain. Conclusion: Physicians have been aware of this type of pain for at least 300 years. Only when researchers studied pathological anatomy and physiology did knowledge accrue. A more comprehensive picture of the disease severity emerged when they also considered its consequences.","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45919486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As migraine and vertigo can both independently modulate attentional processes, here we seek the utility of the attentional network to functionally differentiate patients. Methods: We used the Attentional Network Task (ANT) to elucidate three separate functional networks: Alerting, orienting and resolving conflict. 120 participants had to attend to the direction of a target visual stimulus, while other parameters were simultaneously manipulated. Reaction times across the networks were assessed in, (i) 30 healthy controls, (ii) 30 VM patients, (iii) 30 patients with migraine without vertigo, and (iv) 30 patients with benign paroxysmal positional vertigo (BPPV) but no migraine. Results: Patients with VM (mean = 737.1 ms, SEM = 28), migraine (mean = 735.3 ms, SEM = 36.4), and BPPV (mean = 720.3 ms SEM = 24.3) all exhibited significantly delayed ANT reaction times compared to healthy controls (mean = 661.3 ms, SEM = 23.4). Specific attentional network deficits were observed for resolving conflict in VM, alerting in migraine and orienting in BPPV. Conclusion: VM patients displayed deficits in executive function characterized by an inability to focus attentional resources and suppress peripheral distractors, whereas migraineurs without vertigo exhibited changes in the alerting network that reflects hypervigilance.","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47113175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
