no diagnose after 6 years

[bonbon2220]

My friends daughter has been to over 50 doctors and no one seems to be able to help.
She is 24 years old was totally healthy until she started having bouts of vertigo 6 years ago. She has been treated for everything from mold, lymes, migraines, and any and all holistic medicines. Some have made her much sicker and she literally has been laying flat in bed for the past 6 years other than being transported to hospitals and clinics, only to be sent home with no apparent reason for the dizziness.
At whits end and pray for some relief for my friend and her family.

Hi
Thanks for writing to the forum!
I am sorry to hear about your friend’s daughter. There are various causes for vertigo and a systematic approach is required to reach a diagnosis.
“Vertigo can be caused by disorders of body parts that are involved in maintaining balance:
• Inner ear
• Brain stem and cerebellum
• Nerve tracts connecting the brain stem and cerebellum or within the brain stem
Inner Ear Disorders: Most commonly, vertigo results from motion sickness. Motion sickness may develop in people whose inner ear is sensitive to particular motions, such as swaying or sudden stopping and starting.
Another common cause of vertigo is an abnormal collection of calcium particles in one semicircular canal of the inner ear. The resulting disorder, called benign paroxysmal positional vertigo, or BPPV, is especially common among older people. It occurs when the head is moved in certain ways.
Meniere's disease produces attacks of vertigo. The cause of Meniere's disease is thought to involve excess fluid in the inner ear (hydrops). What triggers this is unknown, but it may result from an autoimmune reaction, an allergy, an imbalance in the autonomic nervous system, a blockage to certain structures in the ear, or a viral infection.
Disorders of the vestibulocochlear nerve can cause vertigo, a hearing disorder, or both.
Other disorders that may cause vertigo by affecting the inner ear or its nerve connections include the following:
• Bacterial or viral infections, such as vestibular neuritis, herpes zoster, and mastoiditis
• Paget's disease
• Tumors, such as an auditory nerve tumor
• Inflammation of nerves
The inner ear may also be damaged by drugs, such as aminoglycoside antibiotics, aspirin
, the chemotherapy drug cisplatin, the sedative Phenobarbital, the anticonvulsant phenytoin, the antipsychotic chlorpromazine and certain diuretics including furosemide Excessive use of alcohol can cause temporary vertigo.
Disorders That Affect the Brain: A decrease in the blood supply through arteries to the brain stem, cerebellum, and back of the brain can cause vertigo. This decrease is called vertebrobasilar insufficiency because the arteries affected include the vertebral and basilar arteries. If the decreased blood supply causes temporary symptoms, a transient ischemic attack (TIA) is diagnosed. If permanent damage results, a stroke is diagnosed.
Less common disorders that cause vertigo by affecting the brain stem or cerebellum include multiple sclerosis, fractures at the base of the skull, head injuries, seizures, infections, and tumors growing in or near the base of the brain. Vertigo can sometimes be part of a migraine attack and occasionally occur without the headache.
Occasionally, vertigo is caused by disorders that suddenly increase pressure within the skull, putting pressure on the brain. These disorders include benign intracranial hypertension, brain tumors, and bleeding (hemorrhage) within the skull.” Refer: http://www.merck.com/mmhe/sec06/ch080/ch080c.html
Hope this helps. I think your friend  should discuss these possibilities with her doctor. It is difficult to comment beyond this without examining. A comprehensive investigation is required keeping all the points in mind. Please let me know if there is any thing else and do keep me posted. Take care!
