Abstract
OBJECTIVE To suggest a comprehensive algorithm for the surgical approach for correcting of sources of temporal bone CSF leaks. METHODS A case series for patients operated in a single academic tertiary referral center between 2011 and 4.2022. Included in the study were 46 patients, 5 of whom had a bilateral problem, resulting in 51 pathologic temporal bones. The presentation was an active CSF leak (38 patients) or bacterial otogenic meningitis (8 patients). Follow up ranged from 8 months to 5 years. RESULTS Of the 42 ears operated via the default middle fossa approach, 37 were successful (88 %) in controlling CSF leak. None had intracranial complications or sensorineural hearing loss. Location, number and size of the defects, hearing status, associated superior semicircular canal dehiscence, additional intra-temporal or intra-cranial pathologies may indicate a transmastoid approach. Of the six ears that had a canal wall up mastoidectomy as a primary procedure, one required revision due to ongoing CSF leak. Five revision cases and three primary cases were effectively sealed with a subtotal petrosectomy and obliteration. One was lost to follow-up. Hearing was reconstructed with bone-anchored hearing implants in 6 out of these 8 ears. CONCLUSIONS The middle fossa approach could be used as a default approach for sealing TD. There are a number of indications for transmastoid approaches in both primary and revision cases. Obliteration of the ear was used in all revision cases. The suggested algorithm can help in planning surgery for temporal bone CSF leaks or a history of otogenic meningitis.

Abstract
OBJECTIVE To evaluate the efficacy of a nonabsorbable, synthetic graft for the reconstruction of spontaneous middle fossa (sMF) cerebrospinal fluid (CSF) leaks. PATIENTS Six adult patients (age ≥16 yr) who had sMF CSF leaks surgically repaired within an 18-month period at a single university hospital using synthetic, nonbiological, nonabsorbable graft (Neuro-Patch) and a retrospective control group of five patients undergoing multilayer MF repair with autologous grafts. INTERVENTIONS MF repair through a combined transmastoid/MF approach using Neuro-Patch or multilayer autologous grafts. MAIN OUTCOME MEASURES The incidence of postoperative leak within 6 months postoperatively was the main outcome measure; we also recorded the need for lumbar drain, additional hearing loss, length of inpatient stay, body mass index, previous meningitis, preoperative increased intracranial pressure, and age. RESULTS In the Neuro-Patch group, there was no postoperative CSF leak without the need for lumbar drain. We observed no additional hearing loss; patients were monitored for 2 days without any readmissions. Increased intracranial pressure (four of six), previous episodes of meningitis (two of six) or obesity (five of six) did not affect patient outcomes. Demographic and prognostic factors were the same for the control group. However, one patient needed lumbar drain postoperatively because of residual leak; lumbar drain was used in one more case (two of five cases), whereas three of five patients had to stay for longer than 2 days (5 d). CONCLUSIONS Our pilot study suggests the use of Neuro-Patch via combined transmastoid/MF approach as an effective technique with minimum, if any morbidity; it could be of particular benefit for patients with larger MF dura defects. A larger number of patients are required to strengthen the evidence.

Abstract
The pathology of idiopathic intracranial hypertension (IIH), a disease characterized by papillary edema and increased intracranial pressure (IICP), is not yet understood; this disease significantly affects quality of life due to symptoms including vision loss, headache, and pulsatile tinnitus. By contrast, superficial siderosis (SS), a disorder in which hemosiderin is deposited on the surface of the cerebral cortex and cerebellum, potentially causes cerebellar ataxia or hearing loss. So far, no cases of IIH with infratentorial and supratentorial cortical SS have been reported. Herein, we report a case of a 31-year-old woman with obesity who developed this condition. The patient suddenly developed headache and dizziness, had difficulty walking, and subsequently became aware of diplopia. Fundus examination revealed bilateral optic nerve congestive papillae and right eye abducens disturbance. Head magnetic resonance imaging (MRI) showed prominent SS on the cerebellar surface and cerebral cortex. Lumbar puncture revealed IICP of 32 cmH2O, consistent with the diagnostic criteria for IIH, and treatment with oral acetazolamide was started; subsequently, the intracranial pressure decreased to 20 cmH2O. Her abduction disorder disappeared, and the swelling of the optic papilla improved. She was now able return to her life as a teacher without any sequelae. SS is caused by persistent slight hemorrhage into the subarachnoid space. In this case, both infratentorial and supratentorial cortical superficial SS was observed. Although cases of IIH complicated by SS are rare, it should be kept in mind that a causal relationship between IIH and SS was inferred from our case. Our findings also suggest that cerebrospinal fluid dynamic analysis using MRI is effective in diagnosing IIH and in determining the efficacy of treatment.

Abstract
BACKGROUND Studies suggest that weight gain is a prominent risk factor for recurrence of papilledema in idiopathic intracranial hypertension (IIH). Given this information, the significant weight gain that occurs during pregnancy, and the fact that pharmacologic therapy is many times discontinued, raises concerns for worsening edema and vision loss. To examine the impact of pregnancy weight gain on IIH, a retrospective chart review of patients with IIH and pregnancy was performed. Compared with previous studies, we 1) quantified findings with optical coherence tomography (OCT) and Humphrey visual field (HVF) data, 2) Included baseline data before pregnancy, 3) determined excess pregnancy weight gain using body mass index-adjusted weight gain goals, and 4) correlated worsening in IIH symptoms with changes in papilledema. METHODS Charts were reviewed for patients with diagnoses of IIH who had at least 2 visits with neuro-ophthalmology during pregnancy. Thirteen patients met inclusion criteria. Data were compared from baseline visits before pregnancy, pregnancy visits, and postpregnancy visits. RESULTS Comparisons of HVF mean deviation (MD), OCT retinal nerve fiber layer (RNFL), and Max OCT RNFL during pregnancy were not significant compared with baseline ( P = 0.51, 0.41, and 0.25). Three patients were found to have increased papilledema during pregnancy (Max Avg OCT RNFL of 152.5, 129, and 123.5 μm) of which 2 developed new reproducible mild visual field defects (HVF ∆MD -1.78 and -4.49). All patients showed more than the 6% weight gain, typically observed in recurrent IIH. Eleven patients gained more than their weight from initial diagnosis. Eight patients had excess pregnancy weight gain. Six patients discontinued pharmacologic therapy for IIH. CONCLUSIONS Weight gain seems to carry a lower risk in IIH patients when associated with pregnancy. This is suggested by the high rate of stable or even decreased disc edema in patients despite medication discontinuation and excess pregnancy weight gain. We postulate these findings may be related to changes in weight distribution or endocrine changes during pregnancy.

Abstract
Idiopathic intracranial hypertension (IIH) is a condition of significant morbidity and rising prevalence. It typically affects young people living with obesity, mostly women of reproductive age, and can present with headaches, visual abnormalities, tinnitus and cognitive dysfunction. Raised intracranial pressure without a secondary identified cause remains a key diagnostic feature of this condition, however, the underlying pathophysiological mechanisms that drive this increase are poorly understood. Previous theories have focused on cerebrospinal fluid (CSF) hypersecretion or impaired reabsorption, however, the recent characterisation of the glymphatic system in many other neurological conditions necessitates a re-evaluation of these hypotheses. Further, the impact of metabolic dysfunction and hormonal dysregulation in this population group must also be considered. Given the emerging evidence, it is likely that IIH is triggered by the interaction of multiple aetiological factors that ultimately results in the disruption of CSF dynamics. This review aims to provide a comprehensive update on the current theories regarding the pathogenesis of IIH.

Abstract
BACKGROUND There are an increasing number of controlled clinical trials and prospective studies, ongoing and recently completed, regarding management options for idiopathic intracranial hypertension (IIH). We present a Common Design and Data Element (CDDE) analysis of controlled and prospective IIH studies with the aim of aligning essential design and recommending data elements in future trials and enhancing data synthesis potential in IIH trials. METHODS We used PubMed and ClinicalTrials.gov to screen for ongoing and published trials assessing treatment modalities in people with IIH. After our search, we used the Nested Knowledge AutoLit platform to extract pertinent information regarding each study. We examined outputs from each study and synthesized the data elements to determine the degree of homogeneity between studies. RESULTS The most CDDE for inclusion criteria was the modified Dandy criteria for diagnosis of IIH, used in 9/14 studies (64%). The most CDDE for outcomes was change in visual function, reported in 12/14 studies (86%). Evaluation of surgical procedures (venous sinus stenting, cerebrospinal fluid shunt placement, and others) was more common, seen in 9/14 studies (64%) as compared with interventions with medical therapy 6/14 (43%). CONCLUSIONS Although all studies have similar focus to improve patient care, there was a high degree of inconsistency among studies regarding inclusion criteria, exclusion criteria, and outcomes measures. Furthermore, studies used different time frames to assess outcome data elements. This heterogeneity will make it difficult to achieve a consistent standard, and thus, making secondary analyses and meta-analyses less effective in the future. Consensus on design of trials is an unmet research need for IIH.

Abstract
PURPOSE To evaluate the effect of weight reduction on the structural and functional parameters of the optic nerve in established cases of papilledema in Idiopathic Intracranial Hypertension (IIH). METHODS A prospective observational study in early and established cases of papilledema in IIH presenting from December 2019 to February 2021. Functional parameters (visual acuity, contrast sensitivity, mean deviation, VER), structural parameters (RNFL, GCL-IPL, and optic disc height), and clinical grading of papilledema were measured at baseline and every 6 weeks for 6 months. All patients underwent medical (oral acetazolamide) and diet therapy. RESULTS Mean body mass index (BMI) at presentation was 26.32 ± 3.52 kg/m² and the mean change in BMI over 6 months was 1.27 ± 0.50 kg/m². 67% of eyes had papilledema of grades 2-3 at the presentation. At the end of 6 months, 75% of eyes had grade 1 papilledema while 13% showed complete resolution. A reduction of 5.32 ± 3.58 in mean deviation (r = 0.316; p-value 0.01) and gain in VER P100 amplitude of 4.2 ± 2.7 µV (r = 0.40; p-value 0.003) were noted over 6 months with reduction in BMI over 6 months. A statistically significant reduction in optic disc height (ODH) was noticed with BMI reduction over 6 months (p = 0.0007; r = 0.45).A reduction of 1.72 ± 0.90 kg/m² (equivalent to 6.53% weight loss) in BMI was associated with a four-grade change in clinical grading of papilledema. CONCLUSION Reduction in BMI had a significant impact on both structural and functional parameters of the optic nerve in IIH. The involvement of a well-certified dietician should be an integral part of treatment in IIH.

Abstract
Background and Objectives Idiopathic intracranial hypertension (IIH) is a syndrome of increased intracranial pressure without an identifiable cause that mostly affects obese persons of childbearing age. In this prospective case series, we have evaluated the overall outcome of pregnancy and birth in participants with IIH and their newborn children. We also provide a proposal for the management of pregnant persons with IIH. Methods In this observational study, neuro-ophthalmological findings, the course of IIH-related symptoms, disease management, and pregnancy outcomes were evaluated. The participants were divided into 3 groups according to the course of the disease during pregnancy: stable, worsened, and new diagnosed. Furthermore, the type of delivery and outcome of newborn children such as gestational age, weight at birth, and the presence of asphyxia were compared between the groups. Results We observed 47 pregnancies in 42 participants; 2 had spontaneous abortions. There were 19 (47%) participants in the stable, 18 (45%) in the worsened, and 3 (8%) in the new diagnosed groups, respectively. A relapse of IIH occurred in 2 (5%). Worsening of IIH-related symptoms was experienced by 18/37 (49%) participants: headache by 17/18 (94%), tinnitus by 11/18 (61%), and vision by 7/18 (39%) (mostly in the first and second trimester). In 8/18 (44%), the symptoms were transient or alleviated in the second and third trimester. Body mass index before and after pregnancy did not significantly differ among the groups. A total of 8 participants were treated with acetazolamide. The frequency of cesarean section was 17/40 (43%). Preterm delivery occurred in 22%. No increased risk of asphyxia was observed, and all infants, but one, were healthy. Discussion Worsening of headache, tinnitus, and/or vision were experienced by half of pregnant participants with IIH, mostly transient in the first and second trimester, rarely required specific treatment, and were not identified as a relapse of IIH. There was no difference in gestational age and weight at birth in children among the groups, and no perinatal asphyxia was noted. Weight gain in the participants was not identified as a risk factor for relapse of IIH in pregnancy. The rate of cesarean and preterm delivery was higher than in the non-IIH population. A proposal for the management of IIH in pregnancy is provided.

Abstract
PURPOSE Idiopathic intracranial hypertension (IIH) is associated with intracranial abnormalities, although not obligatory, which can be detected with cranial MRI. Obesity is an important risk factor for IIH and a pathogenetic link is suspected but the extent to which these MRI signs are already related to obesity has not yet been examined. We investigated whether IIH-MRI signs are present more often in obese individuals with a BMI > 30 kg/m² than in individuals of normal weight. MATERIALS AND METHODS Brain MRI of 32 obese and 53 normal-weight participants from the Food-Chain-Plus cohort were analyzed for three main signs of IIH: (I) stenosis of the transverse sinus, (II) increased width of the optic nerve sheath, and (III) reduction of pituitary height. In addition, a scoring system for the MRI signs was applied. Furthermore, tortuosity of the optic nerve and flattening of the posterior globe were considered as additional MRI signs. RESULTS Obese participants had a significantly higher MRI score (p < 0.001) than those in the normal-weight cohort, with significant differences in quantitative measurements of cerebral venous sinus stenosis (p < 0.001), widening of the optic nerve sheath (p < 0.05), and flattening of the pituitary gland (p < 0.05) also always being observed more frequently and in a more pronounced manner in the obese group. Furthermore, our findings correlated significantly with BMI and proportionately with hip and waist circumference. CONCLUSION Obese individuals show a significantly higher prevalence of cerebral MRI signs related to IIH. This supports the hypothesis that obesity is a risk factor for possible intracranial hypertension and reinforces the suspicion that obesity is involved in the pathomechanism of IIH. KEY POINTS · Obesity is associated with changes such as those seen in IIH.. · BMI, weight, and body measurements correlate with the expression of MRI signs of IIH.. · To prevent IIH symptoms in obesity, the pathomechanism must be further clarified..

Abstract
The understanding of idiopathic intracranial hypertension (IIH) has evolved over the past few years. Previously, IIH was considered a disease exclusively affecting the neuro-ophthalmic axis, characterized by raised intracranial pressure, headache and papilloedema, and resulting in the risk of severe and permanent visual loss and life-changing disabling headaches. Recent advances have begun to redefine IIH as a probable metabolic disease involving a range of systemic manifestations. More than 95% of individuals affected by the disease are women of reproductive age with obesity. The incidence is rapidly rising and parallels the escalating worldwide obesity rates. Contemporary insights identify associations with insulin resistance, type 2 diabetes and a twofold increased risk of cardiovascular disease in excess of that driven by obesity alone. Adipose distribution in people with IIH, like that in other metabolic diseases, is preferentially centripetal and is associated with changes in intracranial pressure. Evidence now demonstrates adipose tissue dysfunction in people with IIH, involving transcriptional and metabolic priming for lipogenesis and weight gain. Hormonal perturbations are also observed, including a unique phenotype of androgen excess that promotes cerebrospinal fluid secretion. Knowledge of these additional disease features is driving research into novel therapeutic targets and altering the approach to multidisciplinary care.

Abstract
BACKGROUND Idiopathic intracranial hypertension (IIH) is a condition of elevated intracranial pressure without an identifiable cause. It mostly affects young obese women but has been reported in individuals newly diagnosed with anemia or with chronic anemia. The relationship between anemia and IIH is not well elucidated. This study aims to characterize the course of IIH in anemic patients. METHODS Consecutive patients with IIH were recruited from neuro-ophthalmology clinics. Subsequent retrospective chart review obtained information on symptoms, complete blood counts (CBCs), visual acuity, visual fields, and optic disc edema at baseline and follow-up. Anemia was diagnosed by hemoglobin <120 g/L (women) and <130 g/L (men). RESULTS One hundred twenty-three patients with IIH were recruited for this study, and 22.8% (28/123) had anemia. More anemic individuals had mild-to-moderate visual acuity impairment (logarithm of minimum angle of resolution 0.3-1, P = 0.01) and worse automated mean deviation ( P = 0.048). The median follow-up time was 47.4 weeks (interquartile range:20.1-91.8). Fifteen of 28 patients with anemia received anemia treatment and showed a trend toward increased hemoglobin. At follow-up, there were no differences in the visual acuity, but patients with anemia had worse automated mean deviation on visual fields ( P = 0.045). CONCLUSIONS IIH patients with anemia had worse visual function at presentation and worse final visual field parameters. This suggests that CBCs should be obtained for patients with papilledema because it may influence final visual outcome.

Abstract
BACKGROUND Among the complications related to chronic kidney disease (CKD), those of a neurological nature stand out, and for a better quality of life for patients, the diagnosis and treatment of these complications is fundamental. OBJECTIVES This study aimed to assess the effect of hemodialysis on intracranial pressure waveform (ICPw) in patients with chronic kidney disease undergoing hemodialysis and those who are not yet undergoing substitutive therapy. DESIGN AND SETTING An observational study was conducted in two stages at a kidney replacement therapy center in Brazil. The first was a longitudinal study and the second was a cross-sectional study. METHODS Forty-two patients on hemodialysis were included in the first stage of the study. In the second stage, 226 participants were included. Of these, 186 were individuals with chronic kidney disease (who were not undergoing substitutive therapy), and 40 did not have the disease (control group). The participants' intracranial compliance was assessed using the non-invasive Brain4care method, and the results were compared between the groups. RESULTS There was a significant difference between the hemodialysis and non-hemodialysis groups, with the former having better ICPw conditions. CONCLUSIONS Hemodialysis influenced the improvement in ICPw, probably due to the decrease in the patients' extra-and intracellular volumes. Furthermore, ICPw monitoring can be a new parameter to consider when defining the moment to start substitutive therapy.

Abstract
PURPOSE The oculofacial plastic surgeon will more frequently encounter challenges related to overweight and obese patients as the incidence rises. There is a paucity of data in the oculofacial plastic surgical literature regarding this topic. The goal of this review is to detail the role obesity plays in the perioperative course and the considerations for a surgeon treating this patient population. METHODS The authors conducted a computerized search using PubMed, Embase, and Google Scholar. The search terms used were "(obesity OR overweight) AND surgery," "(obesity OR overweight) AND oculoplastic," "(obesity OR overweight) AND oculofacial," "(obesity OR overweight) AND 'facial plastic surgery', " "(obesity OR overweight) AND 'bariatric surgery', " "(obesity OR overweight) AND (pre-operative OR post-operative OR intraoperative," " (obesity OR overweight) AND complications," "(obesity OR overweight) AND (facial plastic surgery) AND complications)," "(obesity OR overweight) AND eyelid," "(obesity OR overweight) AND (nasolacrimal OR 'nasolacrimal duct')," "(obesity OR overweight) AND IIH," "(obesity OR overweight) AND exophthalmos." RESULTS A total of 127 articles, published from 1952 to 2022 in the English language or with English translations were included. Articles published earlier than 2000 were cited for foundational knowledge. References cited in the identified articles were also used to gather further data for the review. CONCLUSIONS Overweight and obese patients pose specific challenges that the oculofacial plastic surgeon should be aware of to better optimize patient outcomes. Multiple comorbidities, poor wound healing, and nutritional deficits all contribute to the complications experienced in this patient population. Further investigation on overweight and obese patients is needed.

Abstract
PURPOSE To present four female-to-male (FTM) transgender patients on testosterone therapy diagnosed with idiopathic intracranial hypertension (IIH). METHODS The authors report 4 consecutive FTM transgender patients on exogenous testosterone diagnosed with IIH at a single institution. RESULTS Patient 1 presented with progressive blurred vision and a central scotoma 10 weeks after starting testosterone cypionate injections for hormonal gender transition. Bilateral grade 5 papilledema was present; the patient underwent bilateral optic nerve sheath fenestration with improved vision and resolution of edema. Patient 2 presented with transient vision loss, pulsatile tinnitus, and blurred vision 13 months after starting testosterone cypionate injections. The patient had grade 4 and 3 disc edema of the right and left eyes, respectively. Patient 3 presented with headaches and pulsatile tinnitus and was on testosterone injections at an unknown dose. The examination revealed grade 1 and 2 disc edema of the right and left eyes, respectively. Patient 4 presented with decreased vision, transient visual obscurations, and daily migraines while using topical testosterone gel every other day. Color vision was reduced, and lumbar puncture revealed elevated intracranial pressure. All patients had neuroimaging findings consistent with increased intracranial pressure. CONCLUSIONS Testosterone therapy plays an essential role in FTM hormonal transitioning and may play a role in IIH. Patients undergoing testosterone therapy for gender transition should be informed of the possibility of developing IIH while on treatment, with obesity possibly increasing this risk. Comprehensive eye examinations should be considered in these patients before initiating hormone therapy.

Abstract
BACKGROUND Idiopathic Intracranial Hypertension (IIH) is a rare disorder, linked to severe obesity. The study aimed to evaluate long-term effects of metabolic and bariatric surgery (MBS) on IIH outcomes. METHODS Retrospective study of patients with IIH and severe obesity who underwent MBS. Data were retrieved from prospectively maintained databases of two bariatric surgeons. RESULTS Thirteen patients were included, of them 12 women. Median age was 36 (interquartile range;IQR 21,47) years and body mass index (BMI) was 40.4 (IQR 37.8,41.8) kg/m2. All patients had visual disturbances,12/13 had headaches, and 6/13 had tinnitus. The mean opening pressure on lumbar puncture was 45 cmH2O, and 11/13 patients had papilledema. Medications for IIH were consumed by 11/13 patients, and 2/13 patients had prior surgical intervention for IIH. MBS types included sleeve gastrectomy (n=7), adjustable gastric banding (n=2), roux-en-y gastric bypass (n=2), one anastomosis gastric bypass (n=1), duodenal switch (n=1). At a median follow-up of 10 years (IQR 8,13), the median BMI and total weight loss were 29.7 kg/m2 and 27%, respectively. Remission of symptoms was achieved in 9/13 patients. CONCLUSIONS MBS results in significant and sustainable weight loss, with subsequent resolution or improvement of IIH. It may be considered as a preventive measure for IIH in patients with severe obesity.

Abstract
Intracranial venous pathologies are a historically underrecognized group of disorders that can have a devastating impact on patients. Despite advancements in peripheral venous disorders and arterial neurointerventions, intracranial venous pathologies have received comparatively little attention. Understanding the anatomy, physiology, clinical relevance, and treatment options of intracranial venous pathologies is fundamental to evolving therapies and research priorities. This article provides an overview of major intracranial venous pathologies, the respective pathophysiologies, and treatment options.

Abstract
PURPOSE To characterize the phenotype of patients with idiopathic intracranial hypertension (IIH) who received cerebrospinal (CSF) diversion surgery and to detail the trajectory of recovery. DESIGN Prospective cohort registry study. METHODS Patients with IIH with sight-threatening papilledema presenting to a single United Kingdom neuroscience center between 2019 and 2021 were included. Outcomes consisted of perimetric mean deviation (PMD) and optical coherence tomography measures of papilledema (retinal nerve fiber layer [RNFL]) and macular ganglion cell layer (GCL) in both eyes. Headache outcomes included monthly headache days (MHD). Logistic regression methods were used to model long-term outcomes. RESULTS Fifty-one patients without previous surgical interventions were included (92% female, mean age 28.1 years [SD 8.4], body mass index 37.4 kg/m2 [SD 9.7], mean days of follow-up 330 [SD 209]). Measurements before surgery showed mean PMD -11.4 dB (SD 9.7), RNFL 364 µm (SD 128), Frisén grade papilledema 4.3 (SD 0.9). and MHD 23 (SD 10.6). At 1 month postoperatively, RNFL and PMD had improved by 38% and 4%, respectively. At 4 months postoperatively, papilledema had resolved. GCL declined by 13% over 12 months. MHD reduced by 75% 3 months postoperatively before returning to baseline levels by 12 months. Five patients (9.8%) required revision surgeries. CONCLUSIONS Detailed characteristics of patients with sight-threatening IIH who received CSF diversion surgery and their typical postoperative recovery are presented. These parameters should guide physicians as to when patients with IIH may require surgery and enable the early identification of outliers who fail to respond. Papilledema and PMD recovered but GCL atrophy continued for 12 months. The implication of this delayed atrophy is unknown.

Abstract
For decades, one of the main targets in the management of severe acute brain injury (ABI) has been intracranial hypertension (IH) control. However, the determination of IH has suffered variations in its thresholds over time without clear evidence for it. Meanwhile, progress in the understanding of intracranial content (brain, blood and cerebrospinal fluid) dynamics and recent development in monitoring techniques suggest that targeting intracranial compliance (ICC) could be a more reliable approach rather than guiding actions by predetermined intracranial pressure values. It is known that ICC impairment forecasts IH, as intracranial volume may rapidly increase inside the skull, a closed bony box with derisory expansibility. Therefore, an intracranial compartmental syndrome (ICCS) can occur with deleterious brain effects, precipitating a reduction in brain perfusion, thereby inducing brain ischemia. The present perspective review aims to discuss the ICCS concept and suggest an integrative model for the combination of modern invasive and noninvasive techniques for IH and ICC assessment. The theory and logic suggest that the combination of multiple ancillary methods may enhance ICC impairment prediction, pointing proactive actions and improving patient outcomes.

Abstract
Introduction Effective strategies are required to ensure optimal management of the crucial closure step in endoscopic pituitary surgery. Many surgical techniques have been reported but no significant consensus has been defined. Methods Between January 2006 and March 2022, 3015 adult patients with pituitary adenomas were operated on by a single expert neurosurgical team, using a mononostril endoscopic endonasal approach. Based of preoperative risk factors of and operative findings, a detailed closure strategy was used. Body mass index >40, sellar floor lysis, number of surgeries>2, large skull base destruction, prior radiotherapy were considered as preoperative risk factors for closure failure. All patients treated with an expanded endonasal approach were excluded. Results Patients were mostly women (F/M ratio: 1.4) with a median age of 50 (range: 18 -89). Intraoperative CSF leak requiring specific surgical management was observed in 319/3015 (10.6%) of patients. If intraoperative leak occurred, patients with predictive risk factors were managed using a Foley balloon catheter in case of sellar floor lysis or BMI>40 and a multilayer repair strategy with a vascularized nasoseptal flap in other cases. Postoperative CSF leak occurred in 29/3015 (1%) of patients, while meningitis occurred in 24/3015 (0.8%) of patients. In patients with intraoperative leak, closure management failed in 11/319 (3.4%) of cases. Conclusion Based on our significant 16-year experience, our surgical management is reliable and easy to follow. With a planned and stepwise strategy, the closure step can be optimized and tailored to each patient with a very low failure rate.

Abstract
The ongoing obesity epidemic represents a global public health crisis that contributes to poor health outcomes, reduced quality of life, and >2.8 million deaths each year. Obesity is relapsing, progressive, and heterogeneous. It is considered a chronic disease by the World Obesity Federation (WOF) and a chronic condition by the World Heart Federation (WHF). People living with overweight/obesity are at greater risk for cardiovascular (CV) morbidity and mortality. Increased adiposity (body fat), particularly visceral/abdominal fat, is linked to CV risk and CV disease (CVD) via multiple direct and indirect pathophysiological mechanisms. The development of CVD is driven, in part, by obesity-related metabolic, endocrinologic, immunologic, structural, humoral, haemodynamic, and functional alterations. The complex multifaceted nature of these mechanisms can be challenging to understand and address in clinical practice. People living with obesity and CVD often have concurrent chronic physical or psychological disorders (multimorbidity) requiring multidisciplinary care pathways and polypharmacy. Evidence indicates that intentional weight loss (particularly when substantial) lowers CVD risk among people with overweight/obesity. Long-term weight loss and maintenance require ongoing commitment from both the individual and those responsible for their care. This position paper, developed by the WOF and the WHF, aims to improve understanding of the direct and indirect links between overweight/obesity and CVD, the key controversies in this area and evidence relating to cardiometabolic outcomes with available weight management options. Finally, an action plan for clinicians provides recommendations to help in identifying and addressing the risks of obesity-related CVD (recognizing resource and support variances between countries).

Abstract
Background Rates of spontaneous cerebrospinal fluid leak (sCSF) repairs have increased in recent decades in line with increases in obesity rates. Objectives To determine if the national rate of sCSF leak has continued to rise in recent years and to identify associated risk factors utilizing a comprehensive national database comprising most academic medical centers. Methods A retrospective review from 2009 to 2018 was performed using the Vizient Clinical Database (CDB) of 105 leading academic medical centers in the United States. Patients who underwent CSF leak repair in the CDB database using ICD-9 and ICD-10 diagnostic and procedure codes. Patients with epidural hematomas over the same time frame were used as a control. National rates of craniotomy for sCSF leak repair each quarter were assessed and sCSF leak patient characteristics (age, gender, obesity, hypertension, diabetes) were calculated. Results The rate of craniotomy for all sCSF leak repairs increased by 10.2% annually from 2009 to 2015 (P < 0.0001). There was no statistically significant change in the rate of epidural hematomas over the same period. The rate of lateral sCSF leak repair increased on average by 10.4% annually from 2009 (218 cases/year) to 2018 (457 cases/year) (P < 0.0001). A statistically significant increase was observed across all regions of the United States (P ≤ 0.005). sCSF leak patients had an average (standard deviation) age of 55.0 (13.2) years and 67.2% were female. Obesity was the only demographic factors that increased significantly over time. Likely due to comorbid factors, Black patients comprise a disproportionately large percentage of lateral sCSF leak repair patients. Conclusions The rate of craniotomy for spontaneous CSF leaks continues to rise by approximately 10% annually.

Abstract
OBJECTIVE To report the frequency of radiographic superior semicircular canal dehiscence (SSCD) and tegmen dehiscence in patients with and without obstructive sleep apnea (OSA). STUDY DESIGN Retrospective matched cohort study. SETTING Tertiary care center. PATIENTS Adults with OSA and fine-cut computed tomographic scans including the temporal bone were matched to patients without OSA by age, sex, and type of computed tomography (protocol, scanner type, slice thickness). Ears with otologic surgery or temporal bone tumors were excluded. MAIN OUTCOME MEASURES Prevalence of SSCD and tegmen dehiscence assessed by two independent reviewers. RESULTS The average body mass index of the OSA patients was 29.2 kg/m 2 with an average apnea-hypopnea index of 36.8. The control group had an average body mass index of 26.2 kg/m 2 . Of the 352 temporal bones, 34 (9.7%) had SSCD in the OSA cohort versus 37 (10.5%) in the control group ( p > 0.05). Seven OSA patients (25.6% of those with SSCD) had bilateral SSCD versus 8 controls (27.6% of those with SSCD; p > 0.05). The majority (87.3%) of dehiscences involved the temporal lobe, with the remaining involving the superior petrosal sinus or both. Of the 352 OSA ears, 90 (25.6%) had a tegmen dehiscence versus 95 (27.0%) in the control group ( p > 0.05). Neither group had a laterality preference for SSCD or tegmen dehiscence. CONCLUSION The prevalence of radiographic SSCD and tegmen dehiscences in OSA patients does not significantly differ from age- and sex-matched controls. This is in contrast to a previous case-control study finding patients with symptomatic SSCD to have higher rates of OSA. This may suggest that the effect size of OSA on SSCD prevalence may be limited despite OSA being a risk factor for elevated intracranial pressure.

Abstract
Headache is one of the most common diagnoses in neurology. A thorough understanding of the clinical presentation of secondary headache, which can be life-threatening, is critical. This review provides an overview of the diagnostic approach to a patient with headache, including discussion of "red," "orange," and "green" flags. We emphasize particular scenarios to help tailor the clinical workup to individual circumstances such as in pregnant women, when particular attention must be paid to the effects of blood pressure and hypercoagulability, as well as in older adults, where there is a need for higher suspicion for an intracranial mass lesion or giant cell arteritis. Patients with risk factors for headache secondary to alterations in intracranial pressure, whether elevated (e.g., idiopathic intracranial hypertension) or decreased (e.g., cerebrospinal fluid leak), may require more specific diagnostic testing and treatment. Finally, headache in patients with COVID-19 or long COVID-19 is increasingly recognized and may have multiple etiologies.

Abstract
Idiopathic intracranial hypertension (IIH) primarrily affects obese women of childbearing years and is commonly associated with headaches, pulsatile tinnitus, and vision changes. Though most patients have a "benign" course, it can lead to significant morbidity, including blindness. The treatment approach is based on severity of visual impact and includes weight loss, intracranial pressure lowering medications, and sometimes surgery, such as spinal fluid diversion, optic nerve sheath fenestration, or venous sinus stenting. More studies are needed to determine when surgery is most appropriate and which surgical procedure provides maximal benefit with the least risk.

Abstract
Idiopathic intracranial hypertension is more common among women of reproductive age and is often encountered in pregnancy, either pre-existing and exacerbated by pregnancy-associated weight gain and hormonal changes or arising de novo. We report the case of a 33-year-old woman with progressive visual loss and intractable headache from 20 weeks' gestation requiring ventriculoperitoneal shunting during pregnancy. The risk of permanent maternal vision loss raises complex management dilemmas, when this must be balanced with the fetal and neonatal risks of treatment and possible premature delivery.

Abstract
Idiopathic intracranial hypertension (IIH) is a triad of headaches, visual changes, and papilledema in the absence of a secondary cause for elevated intracranial pressure. There is an association with obesity, and the incidence is rising in parallel with the obesity epidemic. Sometimes these patients present to an otolaryngologist with complaints like tinnitus, dizziness, hearing loss, and otorrhea or rhinorrhea from cerebrospinal fluid leak. IIH diagnosis in conjunction with neurology and ophthalmology, including neuroimaging and lumbar puncture with opening pressure, is key to managing of this condition. Otolaryngologists should recognize IIH as a possible diagnosis and initiate appropriate referrals and treatment.

Abstract
Idiopathic intracranial hypertension is a rare neurological disorder characterized by increased intracranial pressure, which can lead to visual loss and headaches. While medical therapy exists, weight loss is the only disease-modifying treatment. Weight loss is the only therapy that leads to sustained resolution of papilledema. Involving the patient in their disease management through patient engagement is a way to improve disease outcomes, and strengthen the therapeutic relationship. This feature discusses an overview of the disease, a patient's experience, and a physician's perspective.

Abstract
CME: Idiopathic Intracranial Hypertension Abstract. Idiopathic intracranial hypertension is a pressure-induced secondary headache disorder and optic neuropathy. It primarily affects obese women of childbearing age and poses an interdisciplinary challenge both diagnostically and therapeutically. The most common symptom of this disorder are headaches frequently accompanied by photo- and/or phonophobia, whose semiology often resembles that of migraine, followed by transient visual obscurations and pulsatile tinnitus. While protection of visual acuity and visual fields are of first therapeutical priority, adequate headache treatment also plays a key role. In the majority of cases, conservative treatment including weight loss and pharmacological therapy is sufficient. In case of a fulminant disease course or loss of visual function, interventional strategies can be applied additionally. Headache treatment is guided by the predominant semiology.

Abstract
PURPOSE OF REVIEW Idiopathic intracranial hypertension (IIH) is a disorder primarily affecting obese women of childbearing age and, if left untreated, can lead to irreversible vision loss. No consensus exists on the best management strategy for IIH. Weight loss is advocated and few useful medical options exist. There is an unmet need to discover new treatment options for this increasingly prevalent condition. This article reviews the recent advances and research on the treatment of IIH. RECENT FINDINGS Venous sinus stenting (VSS) is now performed in many experienced centers, and there is growing interest in bariatric surgery as a treatment modality. Newly approved anti-obesity drugs are showing effectiveness in weight loss, and novel targeted disease-modifying IIH therapies are being explored. Further evaluation of these novel therapeutic strategies as well as studies exploring the use of anti-obesity drugs in IIH is needed. While VSS is gaining popularity due to its efficacy and low complication rate, there is insufficient evidence to support any surgical procedure over another. Bariatric surgery is appealing for patients with non-sight-threatening IIH and needs to be further explored.

Abstract
BACKGROUND: Idiopathic intracranial hypertension (IIH) is strongly associated with obesity. However, the relationship between cerebrospinal fluid open pressure (CSFOP) and body mass index (BMI) is still controversial.
AIM: The aim of this study is to assess the relationship between CSFOP and BMI in patients with IIH.
METHODS: The measurement of CSFOP was done by Lumbar puncture manometry following a standardized procedure. Age and gender were registered and BMI was calculated for each patient.
RESULTS: This study enrolled 104 patients with IIH, 96 females and eight males, with mean age was 31.88 ± 13.73 years. The mean CSFOP was 410.48 ± 129.98 mm H2O and the mean BMI was 33.97 ± 53 kg/m2. There was a significant positive relationship between the CSFOP and BMI (p = 0.0001) according to the Pearson correlation test. There was no relationship between the age (p = 0.06), gender (p = 0.16) and CSFOP of the patients.
CONCLUSIONS: The CSFOP was positively correlated with high BMI of the patient. There was no relationship between patients demographic features and CSFOP.

Abstract
BACKGROUND The objective of this study was to assess the prevalence of disordered eating behaviors (DEBs) in young individuals with idiopathic intracranial hypertension (IIH) and to identify predictors of DEBs in this population. METHODS Individuals with IIH aged eight to 25 years and their matched controls responded to a self-rating survey comprised of the Eating Attitude Test-26 for assessing the presence of DEBs and the Depression, Anxiety and Stress Scale. RESULTS Fifty-three subjects with IIH and 106 healthy controls were included. DEBs were significantly more prevalent in individuals with IIH (P < 0.001). Individuals with IIH and DEBs were more likely to have longer periods of treatment [odds ratio: 1.07, 95% CI: 1.02-1.41), P = 0.008] and to have lost a significant amount of weight during the course of treatment [odds ratio: 9.06 (95% CI: 1.30-62.9), P = 0.026]. Depression, anxiety, and stress were more prevalent in the IIH group than in the controls (P = 0.004) and were associated with DEBs in these individuals (P = 0.01). CONCLUSIONS There is an increased prevalence of DEBs among young individuals with IIH, which persists even after disease resolution, and is associated with higher reported rates of depression, anxiety, and stress. Medical caregivers should have heightened awareness to DEBs in individuals with IIH with the aim of early identification and intervention.

Abstract
Idiopathic intracranial hypertension (IIH) is a rare pathological condition that without proper therapy often results in permanent vision loss. Diagnosis of IIH is often difficult, since it is characterized by a combination of numerous specific and non-specific ophthalmological and neurological criteria. Difficulties in diagnosis significantly delay the prescription of treatment, which affects the visual prognosis. The description of this clinical case is intended to present our own experience in the diagnosis and management tactics of a patient with this pathology, which will be useful for practicing ophthalmologists.

The Pre-Lumbar puncture Intracranial Hypertension Scale (PLIHS): A practical scale to identify subjects with normal cerebrospinal fluid pressure in the management of idiopathic intracranial hypertension. J Neurol Sci 2021; 429:118058. [PMID: 34461550 DOI: 10.1016/j.jns.2021.118058] [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: 07/05/2021] [Revised: 08/05/2021] [Accepted: 08/24/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Idiopathic Intracranial Hypertension (IIH) diagnosis requires lumbar puncture to measure cerebrospinal fluid (CSF) pressure. The Pre-Lumbar puncture Intracranial Hypertension Scale (PLIHS) is aimed to detect cases that will show raised or normal CSF opening pressure. METHODS Retrospective analysis of records of patients who underwent lumbar puncture for suspect IIH. The target was CSF opening pressure ≥ 250 mmH2O, whereas a set of known neurological, neuro-ophthalmological and neuro-radiological parameters, plus obesity, were used as predictors in a logistic regression model. The PLIHS was based on significant predictors and a cut-off was validated using chi-squared test around CSF opening pressure ≥ 250 and < 200 mmH2O. RESULTS Records of 162 patients were included: CSF opening pressure was <200 mmH2O in 40 and ≥ 250 mmH2O in 95 patients; 85 fulfilled IIH diagnosis. PLIHS is based on Frisén grade 2 or higher papilledema, tinnitus, empty sella, perioptic subarachnoid space distension, and obesity. Score range is 0-7: correlation with CSF opening pressure is 0.508 (p < .001), and PLIHS score is different between subjects not diagnosed with IIH, and those diagnosed with IIH both with and without papilledema (p < .001). PLIHS score ≤ 2 identifies cerebrospinal fluid pressure < 200 mmH2O; PLIHS score ≥ 3 identifies CSF opening pressure ≥ 250 mmH2O, IIH diagnosis, visual acuity ≤0.7, and optic nerve atrophy. CONCLUSIONS The PLIHS, can be used to identify patients who will particularly need LP, thus helping with the organization of the diagnostic work-up by optimising healthcare resources and potentially limit the likelihood to incur in LP-related adverse events.

Abstract
INTRODUCTION Against the backdrop of the diverse minority-majority state of Hawaii, this study seeks to better characterize associations between idiopathic intracranial hypertension (IIH) with sociodemographic variables and medical comorbidities. METHODS A retrospective case-control study was conducted by utilizing 54 IIH patients and 216 age-, sex-, and race-matched controls, 216 unmatched controls, and 63 age-, sex-, and race-matched migraine patients. RESULTS Relative to controls, IIH were 25 years younger (p < 0.0001) and 10.18 kg/m2 heavier (p < 0.0001), as well as exhibited greater odds of the following variables (p < 0.05): female (odds ratio [OR]: 8.87), the lowest income quartile (OR: 2.33), Native Hawaiian or other Pacific Islander (NHPI; OR: 2.23), Native American or Alaskan Native (OR: 16.50), obesity class 2 (35.0-39.9 kg/m2; OR: 4.10), obesity class 3 (>40 kg/m2; OR: 6.10), recent weight gain (OR: 11.66), current smoker (OR: 2.48), hypertensive (OR: 3.08), and peripheral vascular disease (OR: 16.42). Odds of IIH were reduced (p < 0.05) for patients who were Asian (OR: 0.27) or students (OR: 0.30;). Unique from Whites, NHPI IIH patients exhibited greater odds (p < 0.05) for being from lower socioeconomic status and currently smoking, as well as potential association with seizures (p = 0.08). Compared to migraines, IIH headaches were at increased odds of occurring (p < 0.05) occipitally, for greater than 15 days per month, aggravated by postural changes, and comorbid with dizziness and tinnitus. CONCLUSIONS These results not only better characterize IIH, but also highlight socioeconomic and racial disparities in diagnosis.

Abstract
BACKGROUND AND OBJECTIVE Idiopathic intracranial hypertension (IIH) is an increase of intracranial pressure without a known cause, which usually presented with headache. This study aimed to evaluate the changing diagnosis and management approaches of neurologists for IIH in light of recent data. METHODS An online questionnaire about IIH was developed covering 28 questions, and five sections: demographic data, diagnosis, examination, treatment, and follow-up. We compared the approach of neurologists with 1-9 years of experience (group-A) with that of neurologists with more than 10 years' experience (group-B). RESULTS A total of 517 neurologists (group A: n = 252, group B: n = 265) participated in the study. Responder rate of questionarre is 18.3%. The approach to IIH in diagnosis, examination, treatment, and follow-up processes was similar in both groups. The younger group (group A) recognized all neuro-radiologic findings, especially flattening of the posterior aspect of the globe (p = 0.001) and tortuosity of the optic nerve (p < 0.001) at higher rates compared with group B. The most commonly used medical treatment was acetazolamide (99%); corticosteroids were used more frequently by group B (p < 0.001). Optic nerve sheath fenestration (88.3%) was the first-line and ventriculo-peritoneal shunt (70.5%) was the second preferred surgical approach. It was observed that serial lumbar puncture applications (57.0%) were preferred more frequently than venous sinus stenting (19.0%) and bariatric surgery (10.0%). CONCLUSIONS The changing information in the last decade about IIH was more closely followed by younger neurologists despite their lesser experience, but classic methods were preferred in surgical approaches in both groups. Our findings indicated that post-graduate education and guidelines should be disseminated for IIH.

Abstract
The diagnosis and management of idiopathic intracranial hypertension (IIH) can be difficult and multiple medical subspecialities are often involved. Several national and international guidelines regarding the investigations and management of IIH have been published in recent years but still there is no consensus about the optimal organization of IIH-care. The objective of this review was to propose and describe a referral pathway and an organization scheme for diagnosis and management of IIH. An extensive search of existing literature was conducted and summarized. In total, 237 IIH-articles were identified and hereof 43 included. The clinical practice in our specialized IIH-clinic is characterized and described. We conclude that an educational campaign involving medical care providers and patients with chronic headaches is necessary. A detailed organizational proposal for a referral pathway and management of IIH patients based on the literature search and our clinical experience from a highly specialized IIH outpatient clinic is suggested and discussed.

Abstract
BACKGROUND Idiopathic intracranial hypertension (IIH) mostly affects overweight and obese women. Severe obesity is associated with poorer visual outcomes in IIH, and weight gain can precipitate IIH and increase the risk of recurrence. Conversely, weight loss can decrease intracranial pressure and is an effective IIH treatment. Therefore, accurate monitoring of weight and body mass index (BMI) is important to help guide the management of IIH patients. Our goal was to compare estimated and measured BMI among patients with presumed IIH and non-IIH controls to determine whether these vital signs should be systematically measured when evaluating patients for IIH. METHODS A retrospective chart review was performed of consecutive patients with reported and measured weight and height seen in one ophthalmology-based neuro-ophthalmology clinic for IIH between January 2, 2018 and September 10, 2018. Patients with IIH or presumed IIH were compared to non-IIH controls, matched according to age (±5 years), BMI (±5 kg/m unless ≥40 kg/m), sex, and race. Patients with confirmed IIH were asked to self-report their weight when seen in follow-up and they were weighed to compare their self-reported vs measured percent weight change. RESULTS We included 379 subjects (140 patients; 239 controls) among whom 75 of the IIH patients were matched to non-IIH controls. Patients with presumed or definite IIH accurately estimated their height and generally underestimated their weight by a median of 1.8 kg (4 lb), resulting in a median BMI underestimate of 0.9 kg/m. There was no difference in BMI underestimation when comparing presumed or definite IIH patients to matched non-IIH controls while controlling for insurance status, smoking, diabetes, and vascular disease (P = 0.66). As BMI increased, all subjects underestimated their BMI more (by 0.9% per 10 measured BMI unit increase), when controlling for age, sex, and race (P < 0.003). Sixteen confirmed IIH patients were seen in follow-up. At initial neuro-ophthalmology consultation, these subjects underestimated their weight by a mean of 3.2%. At last follow-up they underestimated their weight by only 1.2% (P = 0.03). CONCLUSIONS There was no evidence that IIH or presumed IIH patients had a different perception of their weight than non-IIH controls at initial neuro-ophthalmology consultation. Both patients and matched controls tended to underestimate their weight by the same amount, resulting in an overall BMI underestimation of approximately 1% per 10 measured BMI unit increase. Heavier subjects tended to underestimate their body weight and resultant BMI more, and IIH patients tended to estimate their weight more accurately at follow-up. Our results emphasize the need to systematically objectively measure the weight of presumed IIH patients seen in an ophthalmology clinic.

Abstract
Pseudotumor cerebri, or idiopathic intracranial hypertension (IIH), is a syndrome of elevated intracranial pressure (ICP) of unknown etiology that occurs predominantly in obese women of childbearing age. Pseudotumor cerebri literally means "false brain tumor". It is a "diagnosis of exclusion" therefore a complete work-up to rule out life-threatening causes for increased ICP must be performed through a comprehensive history, complete physical examination, diagnostic imaging, and cerebrospinal fluid (CSF) analysis before the diagnosis can be made. The authors present the case of a young woman with headache, and near blindness due to pseudotumor cerebri. The presentation, diagnosis, and treatment options are discussed.

Abstract
BACKGROUND This aim of this study was to assess the effect of idiopathic intracranial hypertension (IIH) in the development of intracranial hypertension by measuring patients' cerebrospinal fluid (CSF), brain, and segment volumes. IIH is a disease of unknown cause characterized by chronic CSF pressure elevation and papillary edema. Under the Monro-Kellie doctrine, efforts have been made to explain the disease through an increase in the volumes of one or two of brain, blood or CSF in the intracranial cavity, although these have not been completely successful. METHODS Twelve IIH patients diagnosed based on the modified Dandy criteria and 15 age- and sex-compatible healthy controls were included in the study. Cases' 3D T1 sequence images were evaluated using the voxel-based volumetric analysis system (volBrain). Intracranial cavity extraction, macrostructures, and subcortical structure volumes were measured and compared. RESULTS No statistically significant differences were observed between control cases' and IIH patients' CSF, cerebrum, cerebellum, brainstem, and subcortical structure volumes. CONCLUSION IIH arises from a chronic cause that does not impair the volumetric balance between structures inside the intracerebral cavity.

Abstract
Idiopathic intracranial hypertension is a syndrome of increased intracranial pressure of unknown cause that most often occurs in women of childbearing age. Most patients are overweight or obese with a history of recent weight gain. Following a brief review of the symptoms and signs, we discuss the approach to assessment and monitoring of this condition. We then present a practical approach to treatment. Because patients frequently struggle with weight loss and can also have refractory headaches and coexisting psychosocial issues, we emphasize the importance of a multidisciplinary approach to the management of this common condition.

Abstract
There is increasing evidence and appreciation of idiopathic intracranial hypertension (IIH) in medicine. The pathological processes underlying raised intracranial pressure are being studied, with new insights found in both hormonal dysregulation and the metabolic neuroendocrine axis. These will potentially lead to novel therapeutic targets for IIH. The first consensus guidelines have been published on the investigation and management of adult IIH, and the International Headache Society criteria for headache attributable to IIH have been modified to reflect our evolving understanding of IIH. Randomized clinical trials have been published, and a number of studies in this disease area are ongoing.
