Dysequilibrium of ageing (presbyastasis)

Area of Science:

• Otolaryngology
• Geriatrics
• Neurology

Background:

• Dizziness is a common complaint in patients over 65.
• A thorough neurotologic evaluation is crucial for diagnosing dizziness in the elderly.

Purpose of the Study:

• To investigate the causes of dizziness in patients over 65.
• To classify and understand primary dysequilibrium of ageing (presbyastasis).

Main Methods:

• Reviewed clinical findings of 740 patients over 65 presenting with dizziness.
• Performed neurotologic evaluations to identify specific causes.
• Classified dysequilibrium of ageing based on dizziness characteristics.
• Reviewed histological findings of temporal bones in four cases.

Main Results:

• A specific cause of dizziness was identified in 21% of patients.
• Primary dyseququilibrium of ageing (presbyastasis) was diagnosed in 79% of patients.
• Histological findings suggest non-peripheral vestibular changes contribute to presbyastasis.

Conclusions:

• Primary dysequilibrium of ageing is the most common diagnosis for dizziness in older adults.
• Pathological changes beyond the peripheral vestibular system are implicated in presbyastasis.
• Treatment strategies vary from observation to medication and vestibular exercises based on severity.
