Recently a friend of mine was given this diagnosis: Psuedotumor cerebri. She had been having terrible headaches and was experiencing increasingly blurry vision. Today she had an MRI and a spinal tap. Unfortunately, the spinal tap did not get any fluid so she has to have one done again on Monday. The first thing I asked myself was whether or not music might be able to help. Now hopefully on Monday she will at least take her iPod with her and have queued up some music that will distract her from the procedure.
There are many medical procedures that can be greatly eased simply by listening to music through headphones or on an iPod. Think about this when you're told that you need a certain procedure and if possible, plan the music that you want to listen to very specifically in advance. I can program headphones for you, but you can also do it for yourself if you have time.
Papilledema is defined as disc swelling produced by increased ICP; it may be asymmetric, UL, or BL. True optic disc swelling or edema can be a very ominous sign. Acutely, the vision, color vision, and pupillary responses are normal, but the blind spot is increased on visual field testing. Chronic forms lead to loss of vision and loss of visual fields. Fortunately, most perceived optic disc swelling is a manifestation of a congenital optic disc variation.
Differential Diagnosis
Pseudotumor cerebri
–Other symptoms: Headache, nausea, and vomiting all worse in morning, transient visual obscurations, diplopia
–Diagnosis includes increased ICP, normal imaging, normal CSF
–More common in obese females
Optic neuritis
–May be associated with postviral syndromes or meningoencephalitis
–Loss of vision, pain on eye movement
–Vision usually improves within a few weeks, but not full recovery
Optic neuropathy
–Compressive: Associated with NF1 and optic nerve glioma, presents with progressive visual loss, strabismus, nystagmus, proptosis
–Infiltrative: From cancers (leukemias, lymphomas), infection, or inflammation (sarcoidosis, TB, toxocariasis, toxoplasmosis, CMV); optic disc swelling, vision loss, and hemorrhages
–Toxic/nutritional optic neuropathy: Symmetric neuropathy from nutritional deficiency (thiamine, B12), drugs (tobacco/alcohol, chloramphenicol, rifampin), toxins (lead, methanol); visual field and vision loss; may recover with treatment
–Leber optic neuropathy: Mitochondrial DNA transmission, presents late teens to middle 20s; visual field and vision loss, may spontaneously improve
Increased ICP: Idiopathic intracranial hypertension, intracranial hemorrhage, space-occupying lesion
Growth hormone supplementation
Retinal hemorrhage and loss of vision
Retinal vein occlusion
Malignant hypertension: Associated with retinal hemorrhage, exudates, and cotton wool spots
Optic neuropathy, nonarteritic or arteritic
Demyelinating disease
Infectious conditions: Toxoplasmosis, Lyme disease, Bartonella; hard exudates may be visible funduscopically
Workup and Diagnosis
History
–History of HA, nausea or vomiting, recent viral illness
–Family history of visual loss, neurologic disorder
–PMH or signs and symptoms consistent with known systemic diseases; e.g., hypertension, diabetes, thyroid disease, growth hormone therapy
–Nutritional deficiencies; exposure to toxins such as tobacco or alcohol; recent drug use; exposure to ticks and animals
Physical exam
–Visual acuity, confrontational visual fields, pupillary response, extraocular muscle movements, proptosis
–Dilated fundus evaluation
–Neurologic exam for signs and symptoms of demyelinating disease, localizing deficit
Labs
–Titers for CMV, Lyme, toxocariasis, toxoplasmosis
Radiology
–CT or MRI of the brain and orbits for suspicion of intracranial mass, mass effect or hemorrhage
Studies
–Lumbar puncture may be indicated to establish presence or absence of, or to relieve, increased intracranial pressure
Ophthalmologic consultation to rule out congenital variation to avoid unnecessary and expensive differential testing
Treatment
Condition-dependent: Treatment of underlying systemic disease is often the only treatment
Pseudotumor cerebri and other causes of intracranial hypertension: Weight loss, Diamox or Lasix, planned recumbency, LP shunt or optic nerve sheath fenestration if loss of visual function
Space-occupying lesion or hemorrhage: Neurosurgical intervention
Meningoencephalitis: IV antibiotics
Infectious optic neuropathy: Treat underlying cause and consider systemic steroids (controversial)
Optic neuritis: IV (not oral) steroids
Optic nerve glioma treatment controversial: Observation if slowly progressive, resection if only one nerve involved, radiation if chiasm involved, shunts if increased ICP
Toxic or nutritional: Stop offending toxin or supply nutritional supplementation

i was diagnosed with psuedocerbral tumor when i was 15 years old, i just tunred 24 on december 20th. music makes it worse for me, some may be different but i know for myself music is not a good idea.
