Area of Science:

• Gerontology
• Neuroscience
• Otolaryngology

Background:

• Vestibular disorders are prevalent in the general population and increase with age.
• The relationship between falls and vestibular impairment in older adults is not well understood.
• This study investigates vestibular impairment in older adult fallers versus non-fallers.

Purpose of the Study:

• To determine if older adults who fall have a higher prevalence of peripheral vestibular impairment compared to age-matched healthy controls.
• To compare the characteristics of individuals referred to falls clinics versus neuro-otology clinics.

Main Methods:

• A case-controlled study involving community-dwelling older adults.
• Participants were categorized into three groups: fallers (≥2 falls in 12 months), those with confirmed peripheral vestibular disorders, and healthy non-fallers.
• Quantitative vestibular function tests, gait assessments (FGA), physiological profile assessments (PPA), and subjective symptom measures were administered.

Main Results:

• Clinically significant vestibular impairment was found in 80% of fallers versus 18.75% in healthy controls (P < 0.01).
• Fallers performed worse on gait tasks and reported more falls than both control groups.
• No significant difference in vestibular symptom scores was observed between fallers and those with diagnosed vestibular disorders.

Conclusions:

• Vestibular dysfunction is significantly more common in older adult fallers than non-fallers.
• Individuals attending falls clinics are typically older, more impaired, and report more falls than those seen in neuro-otology clinics.
• Increased awareness and targeted management of vestibular impairments can improve outcomes for older adults who fall.
