I'm asking this question on behalf of my father - he is an otherwise healthy 58 yr old that exercises regularly and tends to take good care of himself. He has had a progressively worse problem the past year that is hard to describe. He states that he has trouble walking in that he feels conscious of walking, almost like he has to try or like he could fall over any second. He states that it has become such a problem that when he walks through the hallways at work he always makes sure that he is right by a wall; he has never fallen once but he feels funny walking, almost like he could any second or that he has to make a conscious effort to walk properly.
Additionally, every once in a while (this has been increasing in frequency) he feels for 1-2 seconds like he loses complete control of himself, like a rug has been pulled out from beneath him, and he has to go sit down. He never falls but he always feels like it. Its not the type of dizziness characterized by the world spinning; visually everything is normal, he just describes it as a momentary loss of control. This never occurs when he is sitting. He is worried that this is the beginning of something.
He has had an MRI of his brain which was normal. He had the test done where they pour warm water into one ear - that indicated a slight imbalance between the ears; they suggested he do therapy but they weren't sure if this would necessarily cause his worsening symptoms since the results weren't that bad. The only other issue he has is a major problem sleeping. He wakes up in the middle of the night, is up for at least 2 hours before he can go back to bed; in turn he is tired during the day. I don't know if this could be contributing or could be due to the same root cause...
Any ideas? What could this be? I have trouble searching it since it isn't really dizziness but rather a more unique sensation.

Without the ability to examine your father and obtain a history, I can not tell you what the cause of his symptoms is. However, I will try to provide you with some possibilities.
The general medical term for gait instability is ataxia. In general, ataxias could be divided into a few groups (1) those with a known external cause such as alcoholism or other medications or drugs (2) those that occur following infection (3) those that are neurodegenerative, due to loss of cerebellar cells because of a primary abnormality in cerebellar cells as opposed to an external cause such as infection (4) due to an inborn error metabolism and/or a genetic defect that disrupts metabolism in cerebellar cells (5) those that occur in the setting of cancer, known as "paraneoplastic ataxias", and (6) others, including those due to neuropathy, what is termed sensory ataxia.
Cerebelllar ataxia is one type of ataxia occuring due to a problem in the cerebellum, one of the structures in the brain involved in coordination (among other things). In some patients, cerebellar ataxia occurs following an infection that affects the nervous system, in which case it often resolves. Chronic alcoholism can cause cerebellar ataxia; stopping alcohol intake can improve the ataxia but if it is severe, some permanent symptoms may remain. In patients with cerebellar stroke, with intensive physical and occupational therapy over weeks to months, symptoms may become minimal and may even resolve completely. In patients with cerebellar ataxia due to a tumor in the cerebellum, removal of the tumor often improves ataxia significantly, though some remaining symptoms may persist due to removal of normal cerebellar tissue following surgery. And so on. With a normal MRI, stroke and tumor are an unlikely cause of your father's symptoms.
For the inborn errors of metabolism, some treatable examples include betalipoproteinemia, adrenomyeloneuropathy, cerebrotendinous xanthomatosis, familial vitamin E deficiency, maple syrup urine disease, pyruvate dehydrogenase deficiency, Refsum disease, and Wilson disease. Certain features in your history and physical examination will suggest these disorders, because they are most often associated with other abnormalities. Many of these disorders begin in childhood or adolescence/young adult-hood. Management typically relies on dietary modification, vitamin/cofactor supplementation, or drugs to reduce the load of the accumulating toxic metabolite, or removal of abnormal proteins from the blood by a procedure called plasmapharesis. These disorders are exceedingly rare in adults, but can occur.
In cerebellar ataxia due to cancer, what is called a paraneoplastic process and can be diagnosed with blood tests, with removal of the tumor and treatment with an intravenous medication or immunosuppresants, cerebellar function improves.
Other types of cerebellar ataxias that are genetic such as the large group of genetic disorders called "spino-cerebellar ataxias", Ataxia-telangiectasia, Friedreich ataxia, and other mitochondrial disorders are being studied, certain modifications may be helpful but there is not a cure. These have specific features that suggest one type versus another and genetic testing is available for some of them.
Other potential causes of ataxia include a parkinson's plus syndrome such as multi-system atrophy. Symptoms can predominantly be gait instability.
Neuropathy, or a problem in the nerves of the hands and legs, can lead to a gait disturbance. Symptoms may also include sensory loss in the feet, burning, and tingling, and in some cases, muscle weakness. The most common cause is diabetes, but there are several other causes. Neuropathy is best diagnosed by physical examination and a test called EMG/NCS.
Disorders of the lower spine, such as spinal stenosis, can also lead to gait problems.
As you can see, there are many many potential causes to your father's symptoms. If he has not been evaluated by a neurologist, this is recommended. If he has seen a neurologist, then seeing one specialized in gait disorders, such as a movement disorders specialist, may be of benefit.
Thank you for using the forum I hope you find this information useful good luck.
i have the same simptoms , i olso did he MRI, after that the doctor tall me that this "dizzness" is not from the head, i did a complete blood analysis and everything wan normal, X-ray to the lang everything was normal , but for me the problem contunues to go bad by the day
one doc. tall me that the problem cames from the poor brain blood flow and he give to me some pills for expanding the blood vanes, it solve the problem a little bit, so u can resarch about it a litlle bit
