Dizziness can be used as a general term for several disturbances of equilibrium, or in the narrow sense for a sensation of imbalance without spinning for short time interval.
I prefer the definition of dizziness as a disequilibrium that lasts few seconds to few minutes, while the sufferer can not define a direction of revolving.
Part of the attack is a fear that the patient may fall, but falling is a rare condition.
Between the attacks the patient feels steady and can walk without any help.
The advantage of relating to dizziness as one medical condition is the prevention of contradictory interpretations of the disturbance in medical records and a discussion between a patient and his medical doctor.
A different approach to the definition includes vertigo, imbalance, pre-syncope.
Essential part of the vertigo is the sensation of spinning movement, leading to the terminology of "spinning dizziness". It can be reported as "my head is moving" or as "the room is moving".
Imbalance does not include a sensation of revolving movement.
The patient reports of a sensation that he is losing his balance and may fall. The risk of falling is real in such patients and it usually occurs in a specific direction. No nausea or vomiting occurs in these patients.
Pre-syncope includes attacks of weakness without loss of consciousness. If the patient is unconscious, even for short duration of time, it is a real syncope.
The auditory system diseases that may include dizziness are: Meniere's Disease, otitis media, acoustic neuroma, Benign paroxysmal positional vertigo (see image above) and labirinthitis.
The Central Nervous System diseases that are associated with dizziness are: Multiple sclerosis, Migraine, Chronic motion sickness.
The systemic diseases and medical conditions are: Anemia (the most common is Iron deficiency anemia), pregnancy (may include anemia, hormonal changes), hypotension, hypoxia, hypoglycemia, hormonal abnormality, Ramsay Hunt syndrome.
Emotional instability: panic disorder, anxiety, depression, hyperventilation.
Mr. Cohen came to me for repeated attacks of severe vertigo and dizziness.
For him, his tinnitus was a symptom that he was ready to tolerate. In the process of treatment he started with disappearance of the severe attacks and remained with low grade vertigo. After one year of treatment he did not have vertigo, but the small episodes of dizziness that attacked him for about one second every time, remained for about 6 months.
Today, when he is free of vertigo for 3 years, he wants to be cured from his tinnitus too. I agree with him that it is important to eliminate all the symptoms.
Mrs. Shachar (Speaks Hebrew and Arabic) started the treatment and when she felt improvement she stopped it without consulting me. Her vertigo attacks came back, and when she tried other treatment, the severity of the attacks increased.
Now, she is again under my care and feels much better.
Mrs. Cohen suffered many years, but used some treatments that enabled her to have relive.
The dysfunction in her vestibular (Equilibrium) system was responsible for her inability to work regularly.
She have a loving husband who enabled her to stay at home.
Mrs. Halio experienced her first attack at work. She went to her office and felt that there is no floor. It was anxiety provoking symptom.
Today she does not have any symptoms.
