The causes of dizziness according to the decreasing incidence are;
1) Benign paroxysmal positional vertigo (BPPV) 20%
2) Vestibular 15%
3) Migraine and motion sensitivity 15%
4) Anxiety and depression 10%
5) Meniere's disease 7%
6) Cerebellar disease 6%
7) Transient ischemic attacks 5%
8) Orthostatic hypotension 4%
Your primary care physician should refer you to a neurologist, cardiologist and ENT specialist for evaluation as the causes can be divided on the system, which is involved;
1) Inner ear or internal ear disease
2) Central nervous system
3) Cardiovascular, or
4) Systemic diseases.
Dizziness and imbalance are amongst the most common complaints in your age.
Although the causes of dizziness are multifactorial, peripheral vestibular dysfunction is one of the most frequent causes. Benign paroxysmal positional vertigo is the most frequent form of vestibular dysfunction, followed by Meniere’s disease. Every factor associated with the maintenance of postural stability deteriorates during aging.
The underlying cause of dizziness can be complex and multi-factorial in your age group.
Dizziness and imbalance can be caused by changes in any of the factors associated with the balance system, be they of sensory, visual, vestibular (internal ear), neurologic, and muscular origin.
Since the causes of dizziness in older people are multi-factorial, management of this disease should be customized according to the etiology of dizziness in each individual. Management of dizziness includes various approaches, including medical and rehabilitative ones as well as the use of prosthetic devices.
Vestibular rehabilitation includes;
1) VOR adaptation exercises to assist the central nervous system to adapt to a change or loss in inputs to the vestibular system,
2) habituation exercises to reduce pathologic responses to a provoking stimulus, and
3) substitution exercises to promote the use of the remaining sensory system.
You may consider consulting an MD in physical medicine and rehabilitation.
Currently, these exercises are found to be effective in treating people with dizziness caused by vestibular dysfunction, anxiety, cerebellar dysfunction, or Parkinson’s disease. Several studies have provided evidence that vestibular rehabilitation exercises are effective in improving postural control, dizziness symptoms, and emotional status in dizzy patients with nonspecific causes.
But I would again like to say here; the anxiety of something serious may be the underlying factor for your dizziness/imbalance/instability etc.
If you have fear of falling:
Various prosthetic devices have been developed to improve postural balance in the elderly. Vibrotactile feedback devices, which fit around the waist and provide augmented feedback about body tilt thorough vibration, have been shown to improve postural balance during quiet standing and walking. Vibrating insoles that enhance sensory input from the lower extremities have been reported to improve postural performance in the elderly.
Oral supplementation with antioxidants such as alpha-lipoic acid and coenzyme Q10 has been shown to reduce age-dependent hair cell loss in the inner ear.
