This study is a prospective cohort study. Investigators plan to include 50 patients in whom the IIH-diagnosis is suspected. Patients are referred from general practitioners, neurologists or ophthalmologists to the Danish Headache Center or admitted to the Neurology ward when the IIH diagnosis is
This study is a multicenter, prospective, population-based cohort study with consecutive inclusion of patients in which the diagnosis of IIH is suspected. This study is carried out in collaboration between the Danish Headache Center, Rigshospitalet-Glostrup, and the Neurological Department at Odense
24 patients with IIH according to the modified Dandy criteria were enrolled. Headache impact test (HIT6), ophthalmological assessment including Frisen classification for papilledema, visual acuity, visual field by perimetry, and visual evoked potentials were performed to the patients.

Primary brain tumors in adults are less common than metastatic tumors. The most frequent are glioblastoma multiforme, metastases, anaplastic astrocytoma, meningioma, pituitary tumors and vestibular schwannoma. 70% of the tumors in adults are supratentorial. The most infratentorial tumors are
The need for non-invasive evaluation of ICP is an active area of study. The current gold standard is intraventricular or intraparenchymal catheters but these are invasive, expensive, and require sedation; and thus the need for an effective non-invasive screening tool. The utility of funduscopy in
Research design This study is a double blind randomized clinical trial to determine differences in wave amplitude P50 and N95 on pattern ERG examination, visual field defects (LP) with Humphrey HFA (Humphrey Field Analyzer) II-i 750, 24-2 threshold and ganglion cell thickness with OCT CirrusTM
Hypophosphatasia (HPP) is a rare genetic disorder characterized the abnormal development of bones and teeth. These abnormalities occur due to defective mineralization, the process by which bones and teeth take up minerals such as calcium and phosphorus. These minerals are required for proper
Screening evaluation: Screening will include standard-of-care IIH evaluation including general medical and neurological examinations, blood chemistries, complete blood count, prothrombin time (PT),partial thromboplastin time (PTT), and pregnancy test. Ophthalmological evaluation will include visual
Despite the fact that the results of venous stenting in IIH are still preliminary, it suggests that this technique could become a viable alternative for medically refractory IIH patients with transverse sinus stenosis. However, prospective studies with long-term, standardized and independent
Clinical Phase: Phase II Investigators: NORDIC Network sites Study Centers: 38 study centers Coordinating Center - University of Rochester Statistical Center - University of Rochester Study Period Planned enrollment duration: 2 years Planned duration of treatment: 6 months followed by open-label
Background
Because of the broad clinical spectrum it is often difficult to establish the diagnosis of cerebral venous thrombosis (CVT). Combined MRI/MRV and contrast-enhanced CT are the most accurate methods for diagnosis of CVT. However these methods are often not available on an emergency basis.
The craniospinal cavity is enclosed by a rigid, non-compressible bone and thus has a constant volume. It is filled with soft tissue (brain, spinal cord and connective tissue), cerebrospinal fluid (CSF) and circulating blood. Intracranial pressure (ICP) is the pressure of the fluid that bathes the
During the follow-up of cystinosis patients under protocol #78-HG-0093 "Use of Cysteamine in the Treatment of Cystinosis", we found that 6 of our NIH patients developed papilledema and were diagnosed with pseudotumor cerebri (PTC), whose occurrence has not been previously reported in cystinosis. The
