Headache 2023. [PMID: 37326332 DOI: 10.1111/head.14582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 05/03/2023] [Accepted: 05/05/2023] [Indexed: 06/17/2023]
Abstract
OBJECTIVE The aim of this study was to describe a cohort of pediatric patients with genetically confirmed familial hemiplegic migraine (FHM). The knowledge of genotype-phenotype correlations may suggest prognostic factors associated with severe phenotypes. BACKGROUND Hemiplegic migraine is a rare disease and data concerning the pediatric population are even more rare as they are often extrapolated from mixed cohorts. METHODS We selected patients who met International Classification of Headache Disorders, third edition criteria for FHM, who had a molecular diagnosis, and whose first attack occurred under the age of 18 years. RESULTS We enrolled nine patients (seven males and two females) first referred to our three centers. Three of the nine (33%) patients had calcium voltage-gated channel subunit alpha1 A (CACNA1A) mutations, five (55%) had ATPase Na+/K+ transporting subunit alpha 2 (ATP1A2) mutations, and one had both genetic mutations. The patients experienced at least one aura feature other than hemiplegia during the first attack. The mean (SD) duration of HM attacks in the sample was 11.3 (17.1) h; 3.8 (6.1) h in the ATP1A2 group, and 24.3 (23.5) h in the CACNA1A group. The mean (SD, range) duration of follow-up was 7.4 (2.2, 3-10) years. During the first year from the disorder's onset, only four patients had additional attacks. Over the course of follow-up, the attack frequency overall was 0.4 attacks/year without a difference between the two groups (CACNA1A and ATP1A2). CONCLUSION The study data show that most of our patients with early-onset FHM experienced infrequent and non-severe attacks, which improved over time. Furthermore, the clinical course revealed neither the appearance of novel neurological disorders or a deterioration of basic neurological or cognitive functioning.

Abstract
Despite that it is commonly accepted that migraine is a disorder of the nervous system with a prominent genetic basis, it is comorbid with a plethora of medical conditions. Several studies have found bidirectional comorbidity between migraine and different disorders including neurological, psychiatric, cardio- and cerebrovascular, gastrointestinal, metaboloendocrine, and immunological conditions. Each of these has its own genetic load and shares some common characteristics with migraine. The bidirectional mechanisms that are likely to underlie this extensive comorbidity between migraine and other diseases are manifold. Comorbid pathologies can induce and promote thalamocortical network dysexcitability, multi-organ transient or persistent pro-inflammatory state, and disproportionate energetic needs in a variable combination, which in turn may be causative mechanisms of the activation of an ample defensive system with includes the trigeminovascular system in conjunction with the neuroendocrine hypothalamic system. This strategy is designed to maintain brain homeostasis by regulating homeostatic needs, such as normal subcortico-cortical excitability, energy balance, osmoregulation, and emotional response. In this light, the treatment of migraine should always involves a multidisciplinary approach, aimed at identifying and, if necessary, eliminating possible risk and comorbidity factors.

Abstract
Spinocerebellar ataxias (SCAs) constitute a heterogeneous group of more than 40 autosomal-dominant genetic and neurodegenerative diseases characterized by loss of balance and motor coordination due to dysfunction of the cerebellum and its efferent connections. Despite a well-described clinical and pathological phenotype, the molecular and cellular events that underlie neurodegeneration are still poorly undaerstood. Emerging research suggests that mutations in SCA genes cause disruptions in multiple cellular pathways but the characteristic SCA pathogenesis does not begin until calcium signaling pathways are disrupted in cerebellar Purkinje cells. Ca2+ signaling in Purkinje cells is important for normal cellular function as these neurons express a variety of Ca2+ channels, Ca2+-dependent kinases and phosphatases, and Ca2+-binding proteins to tightly maintain Ca2+ homeostasis and regulate physiological Ca2+-dependent processes. Abnormal Ca2+ levels can activate toxic cascades leading to characteristic death of Purkinje cells, cerebellar atrophy, and ataxia that occur in many SCAs. The output of the cerebellar cortex is conveyed to the deep cerebellar nuclei (DCN) by Purkinje cells via inhibitory signals; thus, Purkinje cell dysfunction or degeneration would partially or completely impair the cerebellar output in SCAs. In the absence of the inhibitory signal emanating from Purkinje cells, DCN will become more excitable, thereby affecting the motor areas receiving DCN input and resulting in uncoordinated movements. An outstanding advantage in studying the pathogenesis of SCAs is represented by the availability of a large number of animal models which mimic the phenotype observed in humans. By mainly focusing on mouse models displaying mutations or deletions in genes which encode for Ca2+ signaling-related proteins, in this review we will discuss the several pathogenic mechanisms related to deranged Ca2+ homeostasis that leads to significant Purkinje cell degeneration and dysfunction.

Abstract
The relationship between headache and epilepsy is complex and despite the nature of this association is not yet clear. In the last few years, it has been progressively introduced the concept of the “ictal epileptic headache” that was included in the recently revised International Classification of Headaches Disorders 3rd edition (ICHD-3-revised). The diagnostic criteria for ictal epileptic headache (IEH) suggested in 2012 were quite restrictive thus leading to the underestimation of this phenomenon. However, these criteria have not yet been included into the ICHD-3 revision published in 2018, thus creating confusion among both, physicians and experts in this field. Here, we highlight the importance to strictly apply the original IEH criteria explaining the reasons through the analysis of the clinical, historical, epidemiological and pathophysiological characteristics of the IEH itself. In addition, we discuss the issues related to the neurophysiopathological link between headache and epilepsy as well as to the classification of these epileptic events as “autonomic seizure.”

Abstract
Primary headache and attention-deficit/hyperactivity disorder (ADHD) are common disorders in children and adolescences, frequently associated to severe cognitive, emotional, and behavioral impairments. They both are a disabling condition with consequences on family and child's quality of life. Literature data on their association are contrasting. Dopaminergic system dysfunction, brain iron deficiency, and sleep disturbance should be considered to better understand headache and ADHD overlap. In this review, we analyze the complex association between these two diseases and the potential impact on child neurodevelopment.

Abstract
Familial hemiplegic migraine (FHM) is a rare subtype of migraine with aura. A mutation causing FHM type 3 (FHM3) has been identified in SCN1A encoding the Nav1.1 Na+ channel. This genetic defect affects the inactivation gate. While the Na+ tail currents following voltage steps are consistent with both hyperexcitability and hypoexcitability, in this computational study, we investigate functional consequences beyond these isolated events. Our extended Hodgkin–Huxley framework establishes a connection between genotype and cellular phenotype, i.e., the pathophysiological dynamics that spans over multiple time scales and is relevant to migraine with aura. In particular, we investigate the dynamical repertoire from normal spiking (milliseconds) to spreading depression and anoxic depolarization (tens of seconds) and show that FHM3 mutations render gray matter tissue more vulnerable to spreading depression despite opposing effects associated with action potential generation. We conclude that the classification in terms of hypoexcitability vs. hyperexcitability is too simple a scheme. Our mathematical analysis provides further basic insight into also previously discussed criticisms against this scheme based on psychophysical and clinical data.

Abstract
BACKGROUND Diagnostic delay is a recognized drawback for a correct management of migraine patients. The aim of this study was to investigate the possible relationship among number and type of examinations performed and diagnostic delay in migraine diagnosis. METHODS We enrolled 500 subjects referred to our Headache Center for a migraine without aura. We analyzed the relationship among diagnostic delay, number of examinations performed and performance of each single test by a Cox regression model and an ordinal logistic regression model. RESULTS Each individual exam increased a diagnostic delay of at least 12 months (p < 0.05, Cox regression model). Brain CT as the first diagnostic approach had a reduced risk of delay of more than 5 years (OR 0.632, 95% CI 0.71-0.56, p < 0.05, ordinal regression model). CONCLUSIONS The number of instrumental examinations seems to significantly influence the diagnostic delay. This aspect contributes to increase health care costs, the risk of pain chronicization and pharmacological treatment misuse.

Abstract
BACKGROUND Familial hemiplegic migraine type 1 (FHM-1) is an autosomal dominant form of migraine with aura characterized by recurrent migraine, hemiparesis and ataxia. FHM-1 has been linked to missense mutations in the CACNA1A gene encoding the pore-forming subunit of the neuronal voltage-gated P/Q-type Ca(2+) channel (CaV2.1α1). METHODS Here, we explored the effects of the FHM-1 K1336E mutation on G protein-dependent modulation of the recombinant P/Q-type channel. The mutation was introduced into the human CaV2.1α1 subunit and its functional consequences investigated after heterologous expression in HEK-293 cells using patch-clamp recordings. RESULTS Functional analysis of the K1336E mutation revealed a reduction of Ca(2+) current densities, a ∼10 mV left-shift in the current-voltage relationship, and the slowing of current inactivation kinetics. When co-expressed along with the human μ-opioid receptor, application of the agonist DAMGO inhibited whole-cell currents through both the wild-type and the mutant channels. Prepulse facilitation was also reduced by the K1336E mutation. Likewise, the kinetic analysis of the onset and decay of facilitation showed that the mutation affects the apparent dissociation and reassociation rates of the Gβγ dimer from the channel complex. CONCLUSIONS These results suggest that the extent of G-protein-mediated inhibition is significantly reduced in the K1336E mutant CaV2.1 Ca(2+) channels. This alteration would contribute to render the neuronal network hyperexcitable, possibly as a consequence of reduced presynaptic inhibition, and may help to explain some aspects of the FHM-1 pathophysiology.

Abstract
PURPOSE Epilepsy and migraine frequently show a clinical overlap. An increase in number of electroencephalographic abnormalities, such as centro-temporal spikes (CTS), may be observed in patients suffering from migraine, epileptic abnormalities that are typically in benign epilepsy of childhood with CTS (BECTS). The aim of this study is to better define the role of CTS in children with migraine compared to children with BECTS, in relation with their neuropsychological profile. METHODS Thirty-two children were enrolled and divided into three groups on the basis of their diagnosis: 16 children (eight males and eight females, aged 12.3 ± 2.58 years) affected by BECTS, 8 patients (four males and four females, aged 11.8 ± 3.47 years) affected by BECTS and migraine, and 8 children (four males and four females, aged 13.5 ± 1.79 years) affected by migraine showing CTS abnormalities. A cognitive and neuropsychological assessment was performed, using Wechsler Intelligence Scale for Children-third edition and NEPSY II, in all patients. RESULTS AND CONCLUSIONS A similar neuropsychological impairment was found in patients affected by BECTS and in those affected by BECTS and migraine; a significant deficit in short- and long-term verbal memory was evident in patients affected by migraine and CTS. CTS in patients with migraine can influence the neuropsychological tests, with a possible negative impact on language and learning development.

Abstract
The term “ictal epileptic headache” has been recently proposed to classify the clinical picture in which headache is the isolated ictal symptom of a seizure. There is emerging evidence from both basic and clinical neurosciences that cortical spreading depression and an epileptic focus may facilitate each other, although with a different degree of efficiency. This review address the long history which lead to the 'migralepsy' concept to the new emerging pathophysiological aspects, and clinical and electroencephalography evidences of ictal epileptic headache. Here, we review and discuss the common physiopathology mechanisms and the historical aspects underlying the link between headache and epilepsy. Either experimental or clinical measures are required to better understand this latter relationship: the development of animal models, molecular studies defining more precise genotype/phenotype correlations as well as multicenter clinical studies with revision of clinical criteria for headache-/epilepsy-related disorders represent the start of future research. Therefore, the definition of ictal epileptic headache should be used to classify the rare events in which headache is the only manifestation of a seizure. Finally, using our recently published criteria, we will be able to clarify if ictal epileptic headache represents an underestimated phenomenon or not.

Abstract
INTRODUCTION AND OBJECTIVES Headaches (including migraines) and epilepsy have a high level of comorbidity and may be confused during diagnosis. Although physicians have known for centuries that these two conditions are somehow linked, their relationship remains poorly understood. Herein we describe the known associations between them, their underlying physiopathologic and genetic mechanisms, and the treatments recommended for them. METHOD We have reviewed the most relevant publication of headache/migraine and epilepsy by using the PubMed data base. DESCRIPTION An individual can suffer both from headaches (either migraine and/or other type of headache) and epilepsy, either by chance or because of a common underlying pathology. In these cases, the headache usually occurs at a different moment than the seizure ("interictal headache"). However, headaches sometimes occur simultaneously with, or very close in time to, the seizure: one that occurs at the same time as an epileptic seizure is known as an "ictal epileptic headache" or as "hemicrania epileptica"; one that precedes a seizure is known as a "pre-ictal headache"; and one that follows a seizure is known as a "post-ictal headache". There is a particular type of pre-ictal headache, known as "migralepsy", which occurs during or just after a migraine aura. CONCLUSIONS The terminology and concepts employed to describe possible associations between headaches (mainly migraines) and epilepsy have evolved over time with increasing clinical and physiopathogenic knowledge. Some researchers have suggested eliminating the term migralepsy and using the terms ictal epileptic headache and hemicrania epileptica exclusively and uniformly in all classification systems.

Abstract
Axons are generally considered as reliable transmission cables in which stable propagation occurs once an action potential is generated. Axon dysfunction occupies a central position in many inherited and acquired neurological disorders that affect both peripheral and central neurons. Recent findings suggest that the functional and computational repertoire of the axon is much richer than traditionally thought. Beyond classical axonal propagation, intrinsic voltage-gated ionic currents together with the geometrical properties of the axon determine several complex operations that not only control signal processing in brain circuits but also neuronal timing and synaptic efficacy. Recent evidence for the implication of these forms of axonal computation in the short-term dynamics of neuronal communication is discussed. Finally, we review how neuronal activity regulates both axon morphology and axonal function on a long-term time scale during development and adulthood.
