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. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
This condition is similar to idiopathic intracranial hypertension, however the etiology in this instance is a drug. [16] The most frequent symptoms are headaches, pulsatile tinnitus, diplopia, and impairment of visual acuity. [15] [17] The only observable signs of the condition may be papilledema and bilateral sixth cranial nerve (abducens ...
The study of visual changes and ICP in astronauts on long-duration flights is a relatively recent topic of interest to space medicine professionals. Although reported signs and symptoms have not appeared to be severe enough to cause blindness in the near term, long term consequences of chronically elevated intracranial pressure are unknown. [4]
This is a dangerous sign, indicative of a brain tumor, CNS inflammation or idiopathic intracranial hypertension (IIH) that may become manifest in the near future. Thus, a biopsy is routinely performed prior to the treatment in the initial stages of papilledema to detect whether a brain tumor is present. If detected, laser treatment, radiation ...
Which can result in a variety of neurological symptoms, such as pseudotumor cerebri, chronic fatigue syndrome, different types of headaches, visual disturbances, pulsatile tinnitus and various neurodegenerative diseases.

Symptoms are frequently accompanied by visual disturbances such as gaze paresis, reduced vision, and dizziness. [1] Increased pressures within the skull can cause a compensatory elevation of blood pressure to maintain cerebral blood flow , which, when associated with irregular breathing and a decreased heart rate , is called the Cushing reflex ...
Visual symptoms: “Visual aura is the most common,” says Dr. Natbony. “There are different types of visual aura, but it usually is a partial loss of vision that’s surrounded by colors ...
Traction and inflammatory headaches are symptoms of other disorders, ranging from stroke to sinus infection. Specific types of headaches include: Tension headache; Migraine; Idiopathic intracranial hypertension (headache with visual symptoms due to raised intracranial pressure) Ictal headache; Cluster headache
