Altered static and dynamic functional network connectivity in post-traumatic headache

BackgroundPost-traumatic headache (PTH) is a very common symptom following mild traumatic brain injury (mTBI), yet much remains unknown about the underlying pathophysiological mechanisms of PTH. Neuroimaging studies suggest that aberrant functional network connectivity (FNC) may be an important factor in pain disorders. The present study aimed to investigate the functional characteristics of static FNC (sFNC) and dynamic FNC (dFNC) in mTBI patients with PTH.MethodsWith Institutional Review Board (IRB) approval, we prospectively recruited 50 mTBI patients with PTH, who were diagnosed with ICHD-3 beta diagnostic criteria and 39 mTBI without PTH who were well matched for age, gender and education. Resting-state functional magnetic resonance imaging (fMRI) scanning (3.0 T, Philips Medical Systems, Netherlands), Montreal Cognitive Assessment (MoCA) and headache symptom measurement (headache frequency and headache intensity) were performed. The resting-state fMRI sequence took 8 min and 10 s. Independent component analysis and sliding window method were applied to examine the FNC on the basis of nine resting-state networks, namely, default mode network (DMN), sensorimotor network (SMN), executive control network (ECN), auditory network (AuN), attention network (AN), salience network (SN), visual network (VN), and cerebellum network (CN). The differences in sFNC and dFNC were determined and correlated with clinical variables using Pearson rank correlation.ResultsFor sFNC, compared with mTBI patients without PTH, mTB with PTH group showed four altered interactions, including decreased interactions in SN-SMN and VN-DMN pairs, increased sFNC in SN-ECN and SMN-DMN pairs. For dFNC, significant group differences were found in State 2, including increased connectivity alteration in the DMN with CN, DMN with SMN, and AuN with CN. Significant reduced connectivity changes in the DMN with VN was found in State 4. Furthermore, the number of transitions (r=0.394, p=0.005) between states was positively associated with headache frequency. Additionally, dwell time (r=-0.320, p=0.025) in State 1 was negatively correlated with MoCA score.ConclusionsMTBI patients with PTH are characterized with altered sFNC and dFNC, which could provide new perspective to understand the neuropathological mechanism underlying the PTH to determine more appropriate management, and may be a useful imaging biomarker for identifying and predicting mTBI with PTH.

ICHD-3 is significantly more specific than ICHD-3 beta for diagnosis of migraine with aura and with typical aura

BackgroundIn the emergency room, distinguishing between a migraine with aura and a transient ischemic attack (TIA) is often not straightforward and mistakes can be harmful to both the patient and to society. To account for this difficulty, the third edition of the International Classification of Headache disorders (ICHD-3) changed the diagnostic criteria of migraine with aura.MethodsOne hundred twenty-eight patients referred to the emergency room at the University Hospital of Lübeck, Germany with a suspected TIA were prospectively interviewed about their symptoms leading to admission shortly after initial presentation. The diagnosis that resulted from applying the ICHD-3 and ICHD-3 beta diagnostic criteria was compared to the diagnosis made independently by the treating physicians performing the usual diagnostic work-up.ResultsThe new ICHD-3 diagnostic criteria for migraine with aura and migraine with typical aura display an excellent specificity (96 and 98% respectively), and are significantly more specific than the previous ICHD-3 beta classification system when it comes to diagnosing a first single attack (probable migraine with aura and probable migraine with typical aura).ConclusionsThe ICHD-3 is a highly useful tool for the clinical neurologist in order to distinguish between a migraine with aura and a TIA, already at the first point of patient contact, such as in the emergency department or a TIA clinic.

Primary headache disorders among the adult population of Mongolia: prevalences and associations from a population-based survey

BackgroundIn the ongoing Global Campaign endeavour to improve knowledge and awareness of headache prevalence worldwide, Mongolia is a country of interest. It sits between Russia and China, in which prevalence is, respectively, much higher and much lower than the estimated global mean. We conducted a population-based study in Mongolia both to add to knowledge and to inform local health policy.MethodsUsing standardized methodology with cluster random sampling, we selected Mongolian adults (aged 18–65 years) from five regions reflecting the country’s diversities. They were interviewed by trained researchers, cold-calling at their homes, using the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) structured questionnaire following pilot-testing. ICHD-3 beta diagnostic criteria were applied.ResultsN = 2043 (mean age 38.0 [±13.4] years, 40% urban-dwelling and 60% rural), with a non-participation proportion of 1.7%. Males were somewhat underrepresented, for which corrections were made. The crude 1-year prevalence of any headache was 66.1% (95% CI: 64.0–68.2%), with a strong female preponderance (OR: 2.2; p < 0.0001). Age- and gender-adjusted prevalences were: migraine 23.1% (for females, OR = 2.2; p < 0.0001); tension-type headache (TTH) 29.1% (no gender difference); probable medication-overuse headache (pMOH) 5.7% (trending towards higher in females); other headache on ≥15 days/month 5.0% (for females, OR = 2.2; p = 0.0008). Unclassified cases were only 35 (1.7%). Any headache yesterday was reported by 410 (20.1%; for females, OR = 2.4; p < 0.0001). Only pMOH showed a strong association with age, peaking in middle years with a 5-fold increase in prevalence. Migraine showed a consistent association with educational level, while pMOH showed the reverse, and was also more common among other groups than among participants who were single (never married). Migraine was less common among rural participants than urban (OR: 0.80; p = 0.0326), while pMOH again showed the reverse (OR: 2.4; p < 0.0001). Finally, pMOH (but not migraine or TTH) was significantly associated with obesity (OR: 1.8; p = 0.0214).ConclusionHeadache disorders are common in Mongolia, with, most notably, a very high prevalence of headache on ≥15 days/month corroborated by the high prevalence of headache yesterday. The picture is very like that in Russia, and dissimilar to China. There are messages for national health policy.

The validation of the Hungarian version of the ID-migraine questionnaire

BackgroundDespite its high prevalence, migraine remains underdiagnosed and undertreated. ID-Migraine is a short, self-administrated questionnaire, originally developed in English by Lipton et al. and later validated in several languages. Our goal was to validate the Hungarian version of the ID-Migraine Questionnaire.MethodsPatients visiting two headache specialty services were enrolled. Diagnoses were made by headache specialists according to the ICHD-3beta diagnostic criteria. There were 309 clinically diagnosed migraineurs among the 380 patients. Among the 309 migraineurs, 190 patients had only migraine, and 119 patients had other headache beside migraine, namely: 111 patients had tension type headache, 3 patients had cluster headache, 4 patients had medication overuse headache and one patient had headache associated with sexual activity also. Among the 380 patients, 257 had only a single type headache whereas 123 patients had multiple types of headache. Test-retest reliability of the ID-Migraine Questionnaire was studied in 40 patients.ResultsThe validity features of the Hungarian version of the ID-Migraine questionnaire were the following: sensitivity 0.95 (95% CI, 0.92–0.97), specificity 0.42 (95% CI, 0.31–0.55), positive predictive value 0.88 (95% CI, 0.84–0.91), negative predictive value 0.65 (95% CI, 0.5–0.78), missclassification error 0.15 (95% CI, 0.12–0.19). The kappa coefficient of the questionnaire was 0.77.ConclusionThe Hungarian version of the ID-Migraine Questionnaire had adequate sensitivity, positive predictive value and misclassification error, but a low specificity and somewhat low negative predictive value.

Assessment of efficacy and safety of eslicarbazepine acetate for the treatment of trigeminal neuralgia.

Antiepileptic drugs are the first-line treatment for trigeminal neuralgia (TN). Carbamazepine and oxcarbazepine are the most studied with well-known efficacy. Eslicarbazepine acetate is a third-generation antiepileptic drug that has not previously been evaluated for the treatment of TN. We aim to assess the efficacy, tolerability and safety of eslicarbazepine for TN. Retrospective, open-label, multicentric, intention-to-treat study. We included patients older than 18years who met the ICHD-3 beta diagnostic criteria for TN. We evaluated the variation of intensity and frequency of pain paroxysms before and after treatment with eslicarbazepine. Secondary objectives assessed were tolerability and safety of eslicarbazepine. Eighteen patients were included, 15 women, mean age 65.2years old, mean follow-up 21.1months. The mean number of drugs tested before eslicarbazepine was 2; 10 patients used eslicarbazepine as monotherapy. After the treatment with ESL, the median of pain intensity improved from 9.5 to 2.5 (p<0.001) and the median of pain paroxysms frequency improved from 70 episodes per week to 0.37 (p<0.001). Responder rate was 88.9%; 44.4% became asymptomatic after treatment. Sixty-one per cent of patients presented some adverse event; four patients discontinued eslicarbazepine for this reason. Despite this, 16 patients (88.9%) noticed a good subjective tolerance to eslicarbazepine. The retention rate at 6months was 77.8% and at 12months 61.1%. Our study supports the hypothesis that eslicarbazepine acetate is an effective, safe and well-tolerated treatment for the treatment of TN. Further studies are warranted to corroborate these results. Eslicarbazepine acetate has shown to be an effective, safe and well-tolerated drug for TN. This is the first study that evaluated the efficacy of this drug on TN in humans.

Tolosa-Hunt Syndrome: Appraising the ICHD-3 beta diagnostic criteria.

Introduction The term Tolosa-Hunt Syndrome was first used more than half a century ago to describe painful ophthalmoplegia accompanied by cranial nerve palsies. In the decades since, its diagnostic criteria have evolved considerably. The beta version of the 3rd Edition of the International Classification of Headache Disorders narrows these criteria to require the demonstration of granulomatous inflammation on MRI or biopsy. We believe this may introduce challenges to accurate diagnosis. Discussion Requiring the demonstration of granulomatous inflammation for a diagnosis of Tolosa-Hunt Syndrome may introduce the potential for false negative and false positive diagnoses. Although the disorder presents secondary to granulomatous inflammation, MRI technology may not be able to identify it reliably, and biopsy is not always indicated for its symptomatology. Additionally, several cases have been reported of Tolosa-Hunt Syndrome diagnosed with MRI-confirmed granulomatous inflammation that later prove to be attributable to other pathologies. The emphasis on neuroimaging may therefore exclude some true Tolosa-Hunt Syndrome cases and include others resulting from other latent pathologies that are not visible on MRI. Conclusion We wish to offer several potential modifications to the International Classification of Headache Disorders guidelines for Tolosa-Hunt Syndrome, including making the demonstration of granulomatous inflammation on MRI or biopsy non-mandatory and lengthening patient follow-up to two years for cases in which MRI is unrevealing.

Recognition of Chronic Migraine by Medicine Trainees: A Cross‐Sectional Survey

Chronic migraine is a diagnosis that can be abstracted through the clinical history, although some providers may struggle in properly applying diagnostic criteria. We aimed to learn how well medicine trainees would be able to recognize the diagnostic criteria for chronic migraine and apply that medical knowledge to case vignettes illustrating different symptom interpretation strategies of the identical information. An electronic, anonymous and multiple-choice response questionairre assessing selected trainee characteristics, headache case vignettes, and chronic migraine diagnostic criteria was distributed to all regional medicine program directors and coordinators in Kentucky and surrounding states. Program directors and coordinators could then individually decide whether or not they would forward to their trainees. The primary outcome measure was the frequency of chronic migraine recognition as a function of history style (ie, lumping versus splitting). Secondary outcome measures included recognition of chronic migraine diagnosis as a function of program affiliation (academic versus community), training year, gender, and recognition of ICHD-3 beta chronic migraine diagnostic criteria. Nominal variables were described as counts and percentages, and compared using chi-square tests. Statistical tests were considered to be two-sided and P ≤ .05 was considered to be statistically significant. Statistical analyses were performed using the JMP 11.0.0 (SAS Institute Inc., Cary, NC, USA). Fifty-six medicine trainees completed the survey. Episodic migraine and chronic tension-type headache were correctly recognized by 85.7% and 96.4%, respectively. Chronic migraine was recognized by a greater proportion of trainees when the identical information was presented using a lumped versus split symptom interpretation strategy (24.1% vs 3.6%, chi-square = 6.5, df =1, P = .01). Accurate recognition of chronic migraine was more likely among trainees in community versus academic/university program (40% vs 14.7%, chi-square = 4.4, df = 1, P = .03) and among male versus female trainees (33.3% vs 9.5%, chi-square = 3.9, df = 1, P = .04). Interestingly, accurate recognition of chronic migraine diagnosis was neither related to training year nor correct recognition of the ICHD-3 beta diagnostic criteria for chronic migraine. Despite accurate individual recognition of episodic migraine and chronic tension-type headache, participants were poor at recognizing that features of these primary headache disorders can co-exist to comprise a uniform diagnosis of chronic migraine. Accurate diagnosis of chronic migraine was improved with use of a lumping strategy to the headache history.

Prospective testing of ICHD-3 beta diagnostic criteria for migraine with aura and migraine with typical aura in patients with transient ischemic attacks.

Introduction The International Classification of Headache Disorders 3rd edition beta (ICHD-3 beta) gave alternative diagnostic criteria for 1.2 migraine with aura (MA) and 1.2.1 migraine with typical aura (MTA) in the appendix. The latter were presumed to better differentiate transient ischemic attacks (TIA) from MA. The aim of the present study was to field test that. Methods Soon after admission, a neurologist interviewed 120 consecutive patients diagnosed with TIA after MRI or CT. Semi-structured interview forms addressed all details of the TIA episode and all information necessary to apply the ICHD-3beta diagnostic criteria for 1.2, 1.2.1, A1.2 and A1.2.1. Results Requiring at least one identical previous attack, the main body and the appendix criteria performed almost equally well. But requiring only one attack, more than a quarter of TIA patients also fulfilled the main body criteria for 1.2. Specificity was as follows for one attack: 1.2: 0.73, A1.2: 0.91, 1.2.1: 0.88 and A1.2.1: 1.0. Sensitivity when tested against ICHD-2 criteria were 100% for the main body criteria (because they were unchanged), 96% for A1.2 and 94% for A1.2.1. Conclusion The appendix criteria performed much better than the main body criteria for 1.2 MA and 1.2.1 MTA when diagnosing one attack (probable MA). We recommend that the appendix criteria should replace the main body criteria in the ICHD-3.

Episodic Syndromes That May Be Associated With Migraine - Two Clinically Useful Markers

Objective: To document episodic syndromes that may be related to migraine (International Classification of headache disorders edition 3-beta versions, code 1.6) and to suggest two clinically useful markers for diagnosing episodic syndromes. Methods: Children and adolescents aged 3 years to 15 years presenting with recurrent head pain of definite / probable migraine origin were interviewed along with their parents or accompanying family member over a period of 2 years (October 2013 to September 2015). Present and past histories of symptoms suggestive of episodic syndromes were documented. ICHD-3 beta diagnostic criteria applied in all cases. Results: 176 fulfilled the ICHD-3 beta diagnostic criteria for episodic syndromes. Abdominal migraine in 98, brief episodes of vertigo / imbalance suggestive of benign paroxysmal vertigo were reported by 62, Cyclical vomiting in 14 and Benign paroxysmal torticollis in 2.124 (70%) were getting these symptoms when exposed to common migraine triggers in this region. Either a single trigger or combination of triggers precipitated these manifestations. 144 (88%) first or second degree siblings were suffering from migraine (1.1, 1.2, 1.5 or brief migraines). Conclusion: Episodic syndromes are not rare in daily clinical practice. Documenting Common migraine triggers and family history of migraine will make episodic syndrome diagnosis easier in children and adolescents.

Headache attributed to temporomandibular disorders and masticatory myofascial pain.

We investigated the temporal association between temporomandibular disorders (TMD)-related symptoms and headache during TMD treatment for patients who fulfilled the diagnostic criteria for headache attributed to TMD (HATMD) specified in the Diagnostic criteria for TMD (DC/TMD) and International classification of headache disorders (ICHD)-3 beta. The study enrolled 34 patients with HATMD induced by masticatory myofascial pain but not by temporomandibular arthralgia. Facial pain intensity, the pressure pain threshold of pericranial muscles, and maximum unassisted opening of the jaw were assessed at an initial examination and before and after physical therapy. The intensity and frequency of headache episodes and tooth contact ratio were also recorded before and after the intervention. Headache intensity and frequency significantly decreased, and these reductions were temporally related to improvements in facial pain intensity, maximum unassisted opening, and pressure pain threshold during TMD treatment. Linear regression analysis showed significant correlations between facial pain intensity and headache intensity and between tooth contact ratio and pressure pain threshold. Among patients who fulfilled the DC/TMD and ICHD-3 beta diagnostic criteria for HATMD, headache improved during TMD treatment, and the improvement was temporally related to amelioration of TMD symptoms. These findings suggest that sensitization in the central and peripheral nervous systems is responsible for HATMD. (J Oral Sci 58, 195-204, 2016).

Development and Validation of a Four-Item Migraine Screening Algorithm Among a Nonclinical Sample: The Migraine-4.

The present study sought to develop and validate a screening algorithm from the ICHD-3 beta diagnostic criteria for migraine utilizing a nonclinical sample. The goal was to determine the most sensitive and specific symptoms for differentiating migraine from other headache disorders and to validate the derived symptom algorithm as a screening measure. Despite its prevalence and impact, migraine remains under-recognized and under-treated. The U.S. Headache Consortium recommended development and dissemination of validated screening measures as a means to improve diagnosis. Participants were 1829 young adults (71.5% female; 74.4% white; mean age = 19.09 years [SD = 2.05]) who reported headache via computerized diagnostic interview. From this group, 158 were found to have ICHD episodic or chronic migraine and were randomly split into experimental and holdout validation samples. Within the experimental sample, receiver operating characteristic (ROC) curve data were obtained for each candidate symptom (item); backward stepwise logistic regression analysis was performed among the items with the most predictive likelihood ratios to determine the optimal model for differentiating migraine from non-migrainous headache. The retained four-symptom algorithm was then validated among the holdout sample, in which various cutoff points were compared to gold standard diagnosis via ROC curve estimations to determine the optimal operating point (OOP) of the algorithm as a screening measure. Attack duration of 4-72 hours (100% [95% CI = 95-100%]), severity ≥ 5 (91% [82-97%]), photophobia (90% [80-96%]), and phonophobia (90% [80-96%]) showed the highest sensitivity, while vomiting (98% [96-99%]), duration of 4-72 hours (92% [90-94%]), nausea (89% [86-91%]), and headache-related disability (88% [85-91%]) showed the highest specificity. The optimal retained model (Migraine-4) included: duration of 4-72 hours, nausea, photophobia, and phonophobia. Among the holdout validation sample, the OOP was positive endorsement of three out of four symptoms, which had a sensitivity of 94% (95% CI = 87-98%), a specificity of 92% (90-94%), and an area under the curve of 93% (90-96%; +LR = 12.37, -LR = 0.06, PPV = 67%, NPV = 99%). The optimal model shares some similarities with previous models but performed better than prior screeners at differentiating migraine from other headache presentations. The Migraine-4 has utility in identifying migraine among nonclinical and young adult samples. Further research with this measure is warranted to determine its utility with treatment-seeking patients and validity in direct comparison to established screening instruments.

The evaluation of ICHD-3 beta diagnostic criteria for Tolosa-Hunt syndrome: a study of 22 cases of Tolosa-Hunt syndrome.

The objective of the study was to evaluate the amended International Classification of Headache Disorders (third edition, beta version, ICHD-3 beta) with a retrospective analysis. A total of 22 patients diagnosed with painful ophthalmoplegia and Tolosa-Hunt syndrome (THS) in our hospital were retrospectively studied. The following clinical data were collected: symptoms, signs, location of inflammatory tissue, time interval of paresis following the onset of pain, pain and signs of resolution, follow-up and relapse. Pain and diplopia were found in 22 (100 %) and 20 cases (91 %). The sympathetic nerve was involved in 6 cases (27 %). Paresis followed the pain for an average of 8 ± 5.87 days. Serial magnetic resonance imaging (MRI) revealed granulomatous lesion that was visible in 20 patients (91 %). 19 patients (86 %) demonstrated the lesions located in the cavernous sinus, orbital apex or superior orbital fissure. One lesion extended to the intracranial structure. Pain was relieved in 20 cases (91 %) within 72 h and no patient had complete relief from paresis. According to our study, we think the time course of relief should be undefined. Headache location is hard to describe accurately. Normal MRI should be involved in THS diagnoses. The lesion of THS can extend beyond the cavernous sinus and the orbit. The time interval between headache and paresis can exceed 2 weeks.

Medication-overuse headache in China: clinical profile, and an evaluation of the ICHD-3 beta diagnostic criteria.

Although medication-overuse headache (MOH) is common in China, its clinical profile is not yet fully established. Meanwhile, ICHD-3 beta has been published, but its diagnostic criteria require further validation. We retrospectively classified the clinical features of 240 consecutive patients with MOH (55 males, 185 females), whose demographic data, headache features, overused medications (type, quantity, frequency and duration of use), headache-attributed burden, and outcomes were reviewed. We then applied the criteria of the several versions of ICHD (II, IIR and 3-beta) to these patients. Compared with those with other headaches, patients with MOH were more likely to be less well educated (64.6% vs 42.0% for secondary school or lower, p < 0.0001), and on lower annual incomes (72.3% vs 56.0% for an income of Chinese yuan (CNY) 30,000 or less, p < 0.0001). Combination analgesics were the most commonly overused medications, and, caffeine (89.9%), aminopyrine (70.0%), phenacetin (53.9%) and phenobarbital (48.8%) were the most commonly used specific components of these. Only two patients (0.8%) had previously been given the diagnosis of MOH; accordingly, the median time to diagnosis after the estimated onset of the disorder was 4.0 years. The majority of patients (83.7%) improved with treatment. All 240 patients fulfilled the diagnostic criteria for MOH according to ICHD-3 beta; only 134 (55.8%) satisfied the diagnostic criteria for definite MOH according to ICHD-II, while 195 (81.2%) met those of ICHD-IIR. MOH in China is associated with lower educational level and annual income. MOH has rarely been diagnosed and correctly treated in China. ICHD-3 beta appears to be more appropriate for the diagnosis of MOH than previous versions.

EHMTI-0139. Field-testing of the ICHD-3 beta diagnostic criteria for classical trigeminal neuralgia

In the summer of 2013 the International Headache Society (IHS) published the beta-version of the 3rd International Classification of Headache Disorders (ICHD-3 beta) with revised diagnostic criteria for classical trigeminal neuralgia (TN). The TN diagnostic criteria are based on expert opinion and IHS strongly encourages field-testing of the new diagnostic criteria.

Validation of ICHD-3 beta diagnostic criteria for 13.7 Tolosa-Hunt syndrome: Analysis of 77 cases of painful ophthalmoplegia

Three editions of International Classification of Headache Disorders (ICHD) diagnostic criteria for Tolosa-Hunt syndrome (THS) have been published in 1988, 2004 and 2013, in ICHD-3 beta, there have been considerable changes [corrected]. The validity of these new diagnostic criteria remains to be established. We retrospectively identified 77 patients with non-traumatic painful ophthalmoplegia (PO) admitted between 2003 and 2013. We reviewed patients' age at onset and gender, time courses between onset of pain and development of cranial nerve palsy, the cranial nerves involved, imaging findings, therapeutic efficacy of steroid treatment and recurrence of attacks. THS was the most frequent type of PO (46/77). In THS patients, the third cranial nerve was most commonly involved (76.3%). The median time interval between pain and cranial nerve palsy was two days, although in five patients (10.9%) the interval ranged from 16 to 30 days. Definitely abnormal MRI findings were found in 24 patients (52.2%). It is essential to rule out other causes of PO in diagnosing THS, with MRI playing a crucial role in differential diagnosis. It may be helpful to understand and master the entity of THS for researchers and clinicians to adjust the gradation and ranking of the diagnostic criteria.
