Prevalence, clinical characteristics and associated factors of cardiac cephalalgia: A prospective study.

BACKGROUND: The prevalence of cardiac cephalalgia is unknown and there is limited information about its clinical features. We aimed to assess the prevalence of cardiac cephalalgia, its clinical characteristics and associated factors. METHODS: We conducted a prospective study of patients with suspected acute coronary syndrome admitted to the Cardiology Service at Hospital Clínico Universitario Lozano Blesa, Zaragoza, Spain, over a one-year period. We interviewed patients within the first 24 hours of admission using a standardized case-report form to assess the presence of headache in relation to the acute coronary syndrome and its characteristics. RESULTS: We included 438 patients, 381 with confirmed myocardial ischemia. Prevalence of cardiac cephalalgia was 14.2% (n = 54). The most common features were frontal location, pressing quality and moderate intensity. Pain referred to the jaws (aOR 2.61; 95% CI 1.33-5.12; p = 0.005), palpitations (aOR 3.65; 95% CI 1.57-8.50; p = 0.003) and circumflex coronary artery as the culprit artery for the myocardial ischemia (aOR 3.8; 95% CI 1.07-13.74; p = 0.021) were related to cardiac whereas history of hypertension was inversely associated (aOR 0.37: 95% CI 0.18-0.74; p = 0.005). CONCLUSION: The prevalence of cardiac cephalalgia was 14.2%. Our study provides valuable information about cardiac cephalalgia characteristics that suggest revision of current diagnostic criteria.

Spinocerebellar ataxia type 15 caused by missense variants in the ITPR1 gene.

BACKGROUND AND PURPOSE: Spinocerebellar ataxia type 15 (SCA15) is a degenerative, adult onset autosomal dominant cerebellar ataxia, caused almost exclusively by deletions in the inositol 1,4,5 triphosphate receptor type 1 (ITPR1) gene (ITPR1). ITPR1 mediates calcium release from the endoplasmic reticulum, and particularly abounds in Purkinje cells. It plays a pivotal role in excitatory and inhibitory actions on Purkinje cells, and alterations in their balance cause cerebellar dysfunction in ITPR1 knockout mice. To date, only two single missense mutations have been reported to cause SCA15. They were considered pathogenic because cosegregation occurred with disease, and haploinsufficiency was hypothesized as their pathogenic mechanism. METHODS: In this study, three Caucasian kindreds with different heterozygous missense variants in ITPR1 are reported. The main clinical manifestation was a slowly progressive gait ataxia with onset after 40 years of age, with chorea in two patients and hand tremor in another one, concordant with manifestations found in SCA15. RESULTS: The three missense variants identified in ITPR1 were c.1594G>A; p.(Ala532Thr) in Kindred A, c.56C>T; p.(Ala19Val) in Kindred B, and c.256G>A; p.(Ala86Thr) in Kindred C. Every variant was labelled as of unknown significance; however, each one cosegregated with disease and was predicted to be pathogenic by in silico tests. CONCLUSIONS: The three ITPR1 missense variants found in this study exhibited cosegregation with disease, a result that sustains their pathogenicity. Further studies are needed to confirm the role of missense mutations in SCA15.

Theory of mind: a new perspective on cluster headache-a cross-sectional study.

INTRODUCTION: Theory of mind (ToM) is the ability to attribute mental states of self and others, such as beliefs (cognitive ToM) and feelings (affective ToM). Based on the role of the hypothalamus in pain and social cognition, our aim is to determine whether ToM is impaired in patients with cluster headache (CH). METHODS: Cross-sectional study in which 31 episodic cluster headache (ECH) patients outside the bout and 20 matched controls carried out social cognition and executive function tasks. Patients were recruited from an outpatient Headache Unit. RESULTS: Patients performed worse than healthy controls at cognitive ToM (t = 4.2, p < 0.001) task but not at affective ToM. Executive function was also impaired (t = 4.8, p < 0.001) and higher scores at anxiety and depression questionnaires (t = - 2.9, p = 0.006; t = - 3.6, p = 0.001) were reported. There was no correlation between ToM scores and executive function, anxiety and depression symptoms, or disease duration and severity. DISCUSSION: Our results suggest that ECH patients can perceive other people's or selves' feelings (affective ToM) but have more difficulties than healthy subjects at recognizing beliefs (cognitive ToM).

Cardiac cephalalgia: a narrative review and ICHD-3 criteria evaluation.

BACKGROUND: Cardiac cephalalgia is an unusual condition that occurs during an episode of myocardial ischemia. Information about cardiac cephalalgia is scarce and its characteristics and physiopathology remain unclear. Our aim is to provide a narrative review of clinical characteristics and physiopathology of cardiac cephalalgia and to evaluate the current diagnostic criteria.  METHODS: A search through PubMed was undertaken for studies on cardiac cephalalgia published until 20th September 2022. We summarized the literature and provide a comprehensive review of the headache characteristics and possible mechanisms. We also evaluated current International Classification of Headache Disorders third edition diagnostic criteria based on prior reported cases.  RESULTS: In total, 88 cases were found. Headache characteristics were variable. Occipital location and throbbing pain were the most frequently reported. Headache was accompanied in most cases by cardiac symptoms. Criterion B was fulfilled by 98% of cases, criterion C1 by 72%, and criteria C2a and C2b by 37 and 93.2%, respectively. Regarding headache features described in diagnostic criterion C3, 'moderate to severe intensity', 'accompanied by nausea', 'not accompanied by photophobia or phonophobia' and 'aggravated by exertion', were reported in 75, 31, 55 and 55% of cases, respectively. CONCLUSION: Cardiac cephalalgia characteristics are variable and the headache features described in the diagnostic criterion C3 might not be adequate. Given that cardiac cephalalgia can be the manifestation of a life-threatening condition it is important to increase the knowledge about this entity.

Cognitive performance in patients with episodic cluster headache outside and inside the active cluster.

BACKGROUND: Previous studies have shown worse cognitive performance in cluster headache (CH) patients compared to healthy controls; however, little is known about cognitive performance in episodic CH (ECH) patients outside and inside the active cluster (AC). OBJECTIVE: Our aim is to compare cognitive function in ECH patients outside and inside the AC. METHODS: In this cross-sectional, observational study, four neuropsychological tests (Trail Making Test [TMT], Stroop Test [ST], verbal fluency [VF], and Symbol Digit Modalities Test [SDT]) were completed by 21 ECH patients at two different points in time: outside and inside the AC. We also assessed self-reported sleep quality and the presence of anxiety or depressive symptoms. Scores were compared. RESULTS: There was not any difference between the scores of the neuropsychological tests performed outside and inside the AC (TMT-A: 23 vs. 23.5; p = 0.984; TMT-B: 96.5 vs. 85.9; p = 0.104; ST word reading: 101.0 vs. 101.2; p = 0.938; ST color naming: 73.0 vs. 73.4; p = 0.858; ST color word: 44.0 vs. 46.0; p = 0.498; SDMT: 44.0 vs. 44.6; p = 0.961; VF phonemic: 29.5 vs. 30.2; p = 0.714; VF semantic: 20 vs. 21; p = 0.489). We found a worsening in the sleep quality component of the Pittsburgh Sleep Quality Index median scores in patients outside the AC (2 vs. 1; p = 0.046). CONCLUSIONS: Our findings suggest that patients with ECH have a similar cognitive performance outside and during the AC.

Impact of 24-Hour On-Call Shifts on Headache in Medical Residents: A Cohort Study.

BACKGROUND: During 24-hour on-call shifts medical residents are exposed to diverse circumstances such as sleep deprivation and stress. OBJECTIVE: Our aim is to assess the effect of 24-hour on-call shifts on medical residents' headache-related disability. METHODS: The Migraine Disability Assessment Scale (MIDAS), the Headache Impact Test (HIT-6), the Pittsburgh Sleep Quality Index (PSQI), and the Hospital Anxiety and Depression Scale (HADS) questionnaires were administered to medical residents who had never performed on-call shifts at baseline and 6 months after beginning 24-hour on-call shifts. Scores were compared. RESULTS: About 66 medical residents completed this study. About 21.2% (n = 14) had history of migraine, 42.4% (n = 28) had a history of tension-type headache (TTH) and 12.1% (n = 8) had a history of both migraine and TTH. Among medical residents with migraine, the median MIDAS score was significantly higher after starting 24-hour on-call shifts than at a baseline (4.0 vs 8.0; Wilcoxon, P = .001), meaning that, on average, disability increased from little or no disability, to moderate disability. No difference in HIT-6 scores was found. The median score of PSQI and HADS was higher at 6 months (PSQI: 7.0 vs 8.0; P = .003), (HADS: 5.0 vs 8.0; P < .001) for the general group. CONCLUSIONS: In medical residents with migraine, migraine-related disability increased after starting 24-hour on-call shifts. We also found a worsening in depression and anxiety symptoms and self-reported sleep quality in medical residents with and without headache history.

Cognitive Performance in Episodic Cluster Headache.

BACKGROUND: Cluster headache is one of the most disabling of all headache conditions. Although some studies have investigated the psychological profile of patients with cluster headache, research on its impact on cognitive function in patients with episodic cluster headache outside the cluster bout is scant. METHODS: Cross-sectional study to evaluate various aspects of neuropsychological assessment and cognitive function including working memory, selective attention, verbal fluency, and executive function in 40 patients with episodic cluster headache. The patients were compared with 40 age-, gender-, and level of education-matched healthy controls. RESULTS: Episodic cluster headache patients performed significantly worse than healthy controls on all cognitive tests, except for the Interference Score (P = 0.281). They had significantly higher Hospital Anxiety Scale scores (P = 0.002). However, we found no significant association between cognitive performance, anxiety, sleep quality, and disease duration. CONCLUSIONS: Patients with episodic cluster headache outside the bout showed worse executive functioning, working memory, language, and selective attention compared with healthy controls, regardless of the duration of disease or sleep quality.

Circadian rhythm of blood pressure in patients with drug-resistant mesial temporal lobe epilepsy.

OBJECTIVE: To determine whether patients with drug-resistant mesial temporal lobe epilepsy present with an alteration in the autonomic circadian regulation of blood pressure. METHODS: A prospective case‒control study was designed, with a case group comprising patients with drug-resistant mesial temporal lobe epilepsy and a control group comprising healthy volunteers. Twenty-four-hour outpatient blood pressure monitoring was performed to assess the existence of a normal (dipping) or altered (non-dipping) circadian pattern. In addition, analytical and ultrasound parameters (carotid intima-media thickness) of vascular risk and sleep quality were evaluated. RESULTS: Twenty-four subjects were recruited in each study group, amongst whom no demographic differences or history of vascular risk were observed. A higher percentage of participants with a non-dipping pattern was observed in the group of patients with epilepsy (62.5% vs. 12.5, p = 0.001). In the case group, significant differences were also observed in carotid intima-media thickness, with a greater probability of presenting with pathological values (p = 0.022). CONCLUSION: The results suggest a disorder of the central autonomic control of blood pressure in patients with drug-resistant mesial temporal lobe epilepsy, with a greater probability of developing an alteration of the circadian rhythm of blood pressure. This dysfunction may be a factor involved in the increased cardiovascular risk in this population.

Acute migraine management in the emergency department: experience from a large Spanish tertiary hospital.

To assess the characteristics of the management of patients with migraine who present to the emergency department (ED) with a migraine attack. Retrospective, observational study analyzing demographic, clinical, diagnostic and therapeutic characteristics of patients with migraine diagnosis presenting to ED for a migraine attack between 2016 and 2019. We reviewed the clinical records of 847 cases. 82.2% were women with mean age of 34.9 years. 87.2% had episodic migraine and 12.2% chronic migraine. 62.3% (528/847) had taken analgesics before visiting the ED [non-steroidal-anti-inflammatory drugs (NSAIDs) (300/528; 56.9%) and triptans (261/528; 49.5%)]. 25.4% (215/847) received blood testing and 6.4% (55/847) received cranial CT. Medication was administered in 77.2% cases (654/847). The median time-to-treatment was 70 min (IQR 42-120). NSAIDs (81%, 530/654), antiemetics (43.1%, 282/654) and metamizole (39% 255/654) were the most used. Triptans were administered in 7 cases (1.1%) and opioids in 84 (12.8%). At discharge, preventive treatment was prescribed or modified in 8.2% of cases (69/839) and triptans were prescribed in 129 cases (15.3%). 70.5% (592/839) were instructed to follow-up with their primary care provider (PCP), 21.5% (181/839) with a general neurologist and 7.9% (66/839) with a headache specialist. The majority of migraine patients were not receiving the recommended acute migraine-specific medication, both in the outpatient and in the ED setting, being especially remarkable the rare use of triptans in the ED. Furthermore, we found an elevated use of urgent complementary tests, mainly blood tests.

Neurological manifestations of Behçet's disease: Case report and literature review. / Manifestaciones neurológicas de la enfermedad de Behçet: descripción de un caso y revisión de la literatura.

Neurological involvement in Behçet's disease is rare, especially at the onset. It can present in the form of parenchymal changes or as damage to the vascular structures in its nonparenchymal form. The coexistence of both kinds of manifestations in the same patient is exceptional. We report the case of a 32-year-old patient with a history of deep venous thrombosis, who was being treated for holocranial headache, apathy, and oral and genital ulcers. Brain magnetic resonance imaging showed hyperintense lesions in the basal ganglia and white matter, and the vascular study evidenced venous thrombosis of the left transverse sinus. After confirming the diagnosis of Behçet's disease with parenchymal and nonparenchymal cerebral involvement, immunosuppressive and corticosteroid therapy was started, resulting in the remission of the symptoms.

Circadian rhythm and autonomic dysfunction in presymptomatic and early Huntington's disease.

INTRODUCTION: Sleep and circadian rhythm disturbances are common in patients with neurodegenerative diseases such as Huntington's disease (HD). The aim of this study was to evaluate variability in circadian blood pressure (BP) to determine the association between abnormal circadian BP and sleep quality in patients with HD. METHODS: Cross-sectional, multicenter study of 38 HD mutation carriers (23 premanifest and 15 early stage patients) who were compared to 38 age- and sex-matched controls. BP was evaluated by ambulatory blood pressure monitoring (ABPM). Based on the percentage decrease in nocturnal BP, subjects were classified as either dippers (≥10%) or non-dippers (<10%). Sleep quality and daytime sleepiness were measured, respectively, using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Daytime Sleepiness Scale (ESS) and the scores on these indices were correlated with the ABPM findings. RESULTS: Sixty-three percent HD mutation carriers were non-dippers (86.7% of the symptomatic and 47.8% of the premanifest patients) versus 23.7% of controls (p = 0.001). In the HD group, sleep quality was significantly more impaired (PSQI>5) (p = 0.016) with more excessive daytime sleepiness (ESS>9) (p = 0.001) than in the control group. Nocturnal non-dipping was associated with worse sleep quality in patients (p = 0.011) but not in controls. CONCLUSION: These results show that patients with HD present early disturbances in the circadian rhythm of BP and that this altered nocturnal BP is associated with poor sleep quality. These findings suggest the potential role of subtle hypothalamic dysfunction in this population.

Encefalitis Límbica Autoinmune Asociada A Anticuerpos LGI1: Presentación De Un Caso Y Revisión De La Bibliografía / Autoimmune Limbic Encephalitis Associated With LGI1 Antibodies: Case Report And Review Of The Literature

RESUMEN Introducción: La encefalitis asociada a anticuerpos dirigidos contra la proteína 1 inactivada del glioma rica en leucina (LGI1) es una entidad poco frecuente de inicio subagudo que se caracteriza clínicamente por la presencia de alteraciones cognitivas, alteraciones conductuales y crisis epilépticas. El pronóstico en la mayoría de los casos es favorable, aunque son frecuentes los déficits amnésicos residuales. Caso clínico: Mujer de 76 años que comenzó de manera súbita con una serie de crisis tónico - clónicas generalizadas y posterior alteración del nivel de consciencia. Se inició tratamiento anticonvulsivante con discreta mejoría clínica. En la resonancia magnética realizada durante el ingreso se observó hiperintensidad en hipocampo izquierdo en secuencias T2 y T2-FLAIR. Ante la sospecha de encefalitis límbica autoinmune se inició tratamiento inmunomodulador con corticoesteriodes e inmunoglobulinas con mejoría clínica. Posteriormente se detectaron anticuerpos anti - LGI1 en líquido cefalorraquídeo. Conclusiones: La encefalitis autoinmune asociada a anticuerpos anti-LGI1 puede producir clínica neurológica variada y orden de instauración variable, incluso en ocasiones agudo. El tratamiento con inmunoterapia precoz es importante tanto para la mejoría clínica en la fase aguda como para el pronóstico a largo plazo.

Abstract Introduction: Leucine rich glioma inactivated protein 1 (LGI1) antibody encephalitis is a rare disease characterized by subacute memory impairment, behavioral disorders and epileptic seizures. Even most cases have a good outcome, residual cognitive deficits are common. Case report: 76-year-old woman who started with acute onset generalized tonic - clonic seizures and subsequent impaired level of consciousness. Antiepileptic treatment was started with slight clinical improvement. In magnetic resonance imaging performed during admission left hippocampal hyperintensity was seen in T2 and T2-FLAIR sequences. As autoimmune limbic encephalitis was suspected, immunomodulatory treatment with intravenous corticosteroids and immunoglobulins was started with clinical improvement. Afterwards, anti -LGI1 antibodies were positive in cerebrospinal fluid testing. Conclusions: anti - LGI1 antibody related encephalitis can produce different neurological manifestations and diverse onset, even acute. Early immunomodulatory treatment is important to improve both clinical manifestations and long - term outcome.
