The general term dizziness is used by nonmedical people for those symptoms but often refers to a feeling of light-headedness, giddiness, drowsiness, or faintness, all of which must be differentiated from true vertigo, [3 ...
The diagnosis is based on symptoms and a high opening pressure found during a lumbar puncture with no specific cause found on a brain scan. [1] [2] Treatment includes a healthy diet, salt restriction, and exercise. [2] The medication acetazolamide may also be used along with the above measures. [2]
Treatment Low molecular weight heparin [ 1 ] Cerebral venous sinus thrombosis ( CVST ), cerebral venous and sinus thrombosis or cerebral venous thrombosis ( CVT ), is the presence of a blood clot in the dural venous sinuses (which drain blood from the brain ), the cerebral veins , or both.
The proposed treatment has been termed "liberation therapy" though the name has been criticized for suggesting unrealistic results. [14] Balloon angioplasty in a preliminary, uncontrolled, unblinded study by Zamboni improved symptoms in MS in a minority of treated people. [44]
The first study of the human brain at 3.0 T was published in 1994, [13] and in 1998 at 8 T. [14] Studies of the human brain have been performed at 9.4 T (2006) [15] and up to 10.5 T (2019). [16] Paul Lauterbur and Sir Peter Mansfield were awarded the 2003 Nobel Prize in Physiology or Medicine for their discoveries concerning MRI.
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
The treatment for PRES is supportive: removal of the cause or causes and treatment of any of the complications, such as anticonvulsants for seizures. PRES may be complicated by intracranial hemorrhage, but this is relatively rare. The majority of people recover fully, although some may experience some residual symptoms.
Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
