Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a syndrome with signs and symptoms of increased intracranial pressure but where a causative mass or hydrocephalus is not identified Idiopathic intracranial hypertension (IIH) is a disorder of unknown etiology that predominantly affects obese women of childbearing age. [ 1] The primary problem is chronically elevated.. Idiopathic intracranialhypertension denotes the condition of increased ICP without an obvious underlying brain pathological condition (and no evidence of venous thrombosis). Dandy ( 39 ) originally described the presence of symptoms of increased ICP, documented cerebrospinal fluid (CSF) pressures of 250 to 550 mm H 2 O with normal CSF findings, and excluded the possibility of brain tumors with ventriculography Idiopathic intracranial hypertension: consensus guidelines on management. Correspondence to Dr Alexandra J Sinclair, Metabolic Neurology, Institute of Metabolism and Systems Research, University of Birmingham, Birmingham B15 2TT, UK; a.b.sinclair@bham.ac.uk Idiopathic intracranial hypertension, also known as pseudotumor cerebri, is a term for increased intracranial pressure due to unknown causes with no known structural change. The etiology of intracranial hypertension can be divided into two categories: Primary or Intracranial Cause
Abstract. The recent discoveries of the glymphatic and lymphatic systems of the brain have helped advance our understanding of CSF physiology and may allow new insights in the understanding of idiopathic intracranial hypertension (IIH). The clinical and radiologic presentations of IIH appear to be related to congestion of the glymphatic system. Abstract. PURPOSE OF REVIEW Idiopathic intracranial hypertension is a syndrome of increased intracranial pressure of unclear etiology that most often occurs in obese women of childbearing age but can also occur in men, children, and older adults. This article reviews the diagnostic criteria, clinical features, neuroimaging findings, differential. Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a disorder of increased intracranial pressure that occurs mainly in overweight women of childbearing years, often in the setting of weight gain. Its cause is not known (hence the preferred name IIH) Idiopathic intracranial hypertension (IIH), is a disorder of elevated intracranial pressure (ICP) occurring most commonly in obese women of childbearing age
Results. IIH occurs at an average annual incidence rate per 100,000 persons of 1 to 2 for the total population and 19 to 21 in obese females of the reproductive age-group. IIH is a recognized cause of reversible vision loss in adult obese women. The diagnosis of IIH requires a documented elevation of intracranial pressure, normal cerebrospinal. Idiopathic intracranial hypertension (IIH) is a disorder of unknown etiology that predominantly affects obese women of childbearing age. The primary problem is chronically elevated intracranial pressure (ICP), and the most important neurologic manifestation is papilledema, which may lead to progressive optic atrophy and blindness Idiopathic intracranial hypertension is a rare neurological disorder of unknown etiology. It is characterized by symptoms and signs of raise intra cranial pressure, normal brain neuroimaging, and high opening pressure ≥ 280 cm H2O in the presence of normal cerebro spinal fluid constituents. Ten years old thin boy presented with severe throbbing headache, vomiting, and visual obscurations for.
Idiopathic intracranial hypertension is a secondary headache disorder characterized by headaches and visual symptoms. It most frequently occurs in obese women of childbearing age. However, many secondary causes exist, and it may affect children, men, and slim individuals. Prompt recognition, evaluation, and treatment are needed to prevent permanent visual loss The purpose of this study was to review paediatric idiopathic intracranial hypertension and determine the specific characteristics and outcome of the paediatric condition compared with adult idiopathic intracranial hypertension. Methods : Thirteen case notes were retrospectively reviewed (11 females, 2 males) Whether idiopathic intracranial hypertension must be regarded as a differential diagnosis or as a cause, or whether there are common pathophysiological pathways that lead to signs of idiopathic.
Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. The main symptoms are headache, vision problems, ringing in the ears with the heartbeat, and shoulder pain Introduction. Adult idiopathic intracranial hypertension (IIH) is a rare condition of unknown cause, which results in raised intracranial pressure (ICP). 1 Young obese women are most commonly affected, although rarely it may occur in men. The incidence in the UK general population is approximately 4.7 per 100,000 and this has recently increased in parallel with obesity. 2 Typically patients. Whether idiopathic intracranial hypertension must be regarded as a differential diagnosis or as a cause, or whether there are common pathophysiological pathways that lead to signs of idiopathic intracranial hypertension in this wider spectrum of disease is the focus of further study Idiopathic intracranial hypertension (IIH), formerly known as pseudotumor cerebri, is a condition that affects the brain. Pseudotumor cerebri literally translates to false brain tumor.This term was used because symptoms of IIH resemble those of brain tumors depsite no tumor being present Idiopathic intracranial hypertension (IIH) is caused by an elevation of intracranial pressure (ICP). The condition mainly affects obese young women of childbearing age. Its prevalence ranges between 0.5 and 2 per 100,000 of the general population and is expected to increase further given the worldwide increase in obesity . The underlying cause.
Idiopathic intracranial hypertension is common in obese women and can lead to significant visual impairment. First described more than 100 years ago, the cause of the disorder remains unknown. Despite a multitude of proposed links, the aetiology has never been established. Impairment of cerebrospinal-fluid reabsorption is the most likely underlying pathophysiological cause of the raised. Idiopathic intracranial hypertension (IIH), previously known as benign intracranial hypertension or pseudotumor cerebri, is a disabling condition of predominantly young, obese women of childbearing age. The condition results in raised ICP, of no known cause, resulting in visual loss, headaches, and papilledema
The typical patient with idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is diagnosed relatively easily and accurately, based on the Modified Dandy Criteria. When it comes to treatment, however, things get more complicated. Purpose: Idiopathic intracranial hypertension (IICH) is a condition characterized by raised intracranial pressure (ICP), and its diagnosis is established when the opening pressure measured during a lumbar puncture is elevated >20 cm H 2 O in nonobese patients or >25 cm H 2 O in obese patients. Papilledema is caused by forced filling of the.
The presentation of idiopathic intracranial hypertension (IIH) in association with iron deficiency anemia (IDA) is rare. This case report depicts the unusual case of a 31-year-old woman of mixed Jamaican and English heritage with IIH who presented initially as IDA in the context of menorrhagia. Subsequent ophthalmic review, lumbar puncture, cerebrospinal fluid analysis and neuroimaging studies. Paediatric idiopathic intracranial hypertension (IIH), is a rare but important differential diagnosis in children presenting with papilloedema. It is characterised by raised intracranial pressure in the absence of an identifiable secondary structural or systemic cause and is, therefore, a diagnosis of exclusion. In the adult population, there is a strong predilection for the disease to occur.
Patients with idiopathic intracranial hypertension (IIH) and morbid obesity (BMI >40) have poor results with dietary therapy and should be considered for bariatric surgery, which has been shown to be effective.

Idiopathic intracranial hypertension (IHH) is a clinical disorder characterized by symptoms and signs of increased intracranial pressure without abnormal cerebrospinal fluid composition and structural parenchymal abnormalities (1,2) Idiopathic intracranial hypertension has had a number of different names in the century since it was first described by Quincke under the name of 'meningitis serosa' (Quincke 1897). The most commonly used synonyms are 'pseudotumour cerebri' (Nonne 1904) and 'benign intracranial hypertension' (Foley 1955). However, there are problems.
INTRODUCTION. Idiopathic intracranial hypertension (IIH), also called pseudotumor cerebri, is a disorder defined by clinical criteria that include symptoms and signs isolated to those produced by increased intracranial pressure (ICP; eg, headache, papilledema, vision loss), elevated ICP with normal cerebrospinal fluid (CSF) composition, and no other cause of intracranial hypertension evident. This article is from October 2010 and may contain outdated material. Idiopathic intracranial hypertension (IIH), also called pseudotumor cerebri, now affects about 100,000 Americans, and many comprehensive ophthalmologists are likely to see some of these patients in their practices Idiopathic intracranial hypertension IIH is linked to a lack of absorption of cerebro-spinal fluid (CSF) in arachnoid granulations. Outside pregnancy the risk factors of IIH which have been evoked are polycystic ovary syndromes and blood coagulation anomalies as thrombophilia or. Even though the visual prognosis is compromised, there is no risk. INTRODUCTION. Idiopathic intracranial hypertension (IIH) is also commonly called pseudotumor cerebri. It is a disorder defined by clinical criteria that include symptoms and signs isolated to those produced by increased intracranial pressure (eg, headache, papilledema, vision loss), elevated intracranial pressure with normal cerebrospinal fluid composition, and no other cause of intracranial. Idiopathic IH may be diagnosed if you have increased pressure on your brain and no other cause can be found. Treatments for chronic intracranial hypertension. Treatment for intracranial hypertension (IH) depends on the cause, if this is known. The main treatments for idiopathic IH are: losing weight if you're overweight. This can often help to.
Weight loss is the cornerstone of therapy for idiopathic intracranial hypertension. We recommend a low salt, weight reduction diet with loss of about 5 - 10% of body weight followed by stable weight. This goal, of modest weight loss, is more likely to succeed than the usual aggressive weight loss program Background - Idiopathic intracranial hypertension (IIH) is characterized by raised intracranial pressure without any identifiable pathology in the brain and with normal cerebrospinal fluid (CSF) composition. A typical patient of IIH is an obese woman of childbearing age. Headache is the most common symptom. Papilledema, or optic disc swelling is the main finding Idiopathic intracranial hypertension (IIH) is a disorder associated with increased intracranial pressure without evidence of a space-occupying lesion and with normal cerebrospinal fluid constituents Idiopathic intracranial hypertension (IIH) is a headache syndrome characterized by raised CSF pressure in the absence of an intracranial mass lesion or ventricular dilation; normal CSF composition; usually normal results of neurologic examination, except for papilledema and occasional CN VI palsy; and a normal level of consciousness .The hallmark of IIH is papilledema, which may be bilateral. Participants who were female and had active idiopathic intracranial hypertension were enrolled from 5 National Health Service hospitals in the UK. Automated perimetry and OCT imaging were followed immediately by ICP measurement on the same day. Cohort 1 used continuous sitting telemetric ICP monitoring (Raumedic Neurovent P-tel device) on 1.
OBJECTIVES: To evaluate the association between obesity and idiopathic intracranial hypertension (IIH) and establish whether there is a relationship with visual outcome. To calculate the. Idiopathic intracranial hypertension (IIH) is associated with raised intracranial pressure (ICP) and visual involvement .Vision involvement in IIH is secondary to papilledema and generally affects the peripheral field of vision .Fulminant IIH (<3% of cases) causes severe vision loss within four weeks of onset, and the vision loss progresses over days, which has commonly been described in obese. Two useful mnemonics to remember the features of idiopathic intracranial hypertension are: VOMER MOVES Mnemonics VOMER V: ventricles of normal or reduced size O: optic disc protrusion M: Meckel's cave enlargement E: empty sella R: redu.. The use of unilateral dural sinus stent placement in patients with idiopathic intracranial hypertension (IIH) has been described by multiple investigators.

In idiopathic intracranial hypertension there is raised pressure within the skull (raised intracranial pressure), which puts pressure on the brain. Idiopathic means that the cause of this raised pressure is unknown. The main symptoms are headache and loss of sight (visual loss). It mostly affects women of childbearing age who are overweight or. Idiopathic intracranial hypertension (IIH) is a neurological disease characterized by a cerebrospinal fluid (CSF) pressure of more than 25 cmH2O in the absence of structural obstructions or lesions. Patients typically complain about headache (76-94%) and visual disturbance due to the affection of the optic (68.72%) and abducens nerve (18%) The link between idiopathic intracranial hypertension, fibromyalgia, and chronic fatigue syndrome: exploration of a shared pathophysiology.

Endovascular stenting for idiopathic intracranial hypertension with venous sinus stenosis Optic nerve ultrasound is an established routine supplementary diagnostic tool for idiopathic intracranial pressure but it can also be helpful in avoiding misdiagnoses. We describe a case of an obese 15- year-old girl with persistent headaches, fundoscopic findings suggesting papilledema, normal brain imaging who underwent two lumbar punctures with unremarkable cerebrospinal fluid findings.
Pediatric idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure despite normal cerebrospinal fluid and neuroimaging findings. Initial management is typically medical; however, nearly 10% of children will eventually require surgery for persistent headache and/or vision loss Idiopathic intracranial hypertension (IIH) mostly affects obese women in childbearing age, leading to frustrating headache and permanent visual impairment. The exact etiology of this condition is poorly understood, and the population at risk and clinical presentation seems to be homogeneous. However, little attention has been paid to the clinical features of IIH patients with anemia The incidence of idiopathic intracranial hypertension is 1/100,000 population per year or 19.3/100000 in obese women with age between 20 to 44 years [].The only major morbidity associated with IIH is the visual troubles which occur in most of the patients [].Idiopathic intracranial hypertension (IIH) is characterized by signs and symptoms of increased intracranial pressure in a conscious patient Article: Idiopathic Intracranial Hypertension.
