Vestibular Health and Cognitive Decline
Why balance matters for brain health in older adults

We often associate the vestibular system with balance and dizziness, but its role goes far deeper—particularly when it comes to cognitive function and ageing. Emerging research shows a strong link between declining vestibular function and reduced memory, attention, and spatial awareness, especially in older adults.

At Advanced Vestibular Clinics, we take a holistic approach to vestibular health, recognising its potential to influence not just physical stability, but also mental clarity and cognitive resilience.

🧠 The Vestibular-Brain Connection

The vestibular system—located in the inner ear—sends signals to the brain about head movement, spatial orientation, and balance. These signals are closely linked to areas of the brain involved in memory (hippocampus), attention, and executive function.

Studies show that reduced vestibular input may accelerate age-related brain changes. For instance:

• Individuals with vestibular dysfunction may experience reduced hippocampal volume (Kremmyda et al., 2016).
• Vestibular loss is associated with cognitive deficits, particularly in visuospatial tasks (Bigelow & Agrawal, 2015; Smith, 2019).

⚖️ How Vestibular Physiotherapy Can Help

Vestibular rehabilitation isn’t just about treating dizziness—it can:

• Improve balance and coordination
• Stimulate brain areas responsible for navigation and focus
• Support dual-task training (e.g. walking while talking), which helps maintain cognitive and physical function
• Reduce falls and the associated cognitive load from fear and inactivity

👵 Who Is Most at Risk?

Age-related vestibular decline affects more than 35% of adults over 70 (Agrawal et al., 2009). Those with:

• Hearing loss
• Cognitive complaints
• History of falls or dizziness
• Sedentary lifestyles
  are at greater risk of both balance and cognitive issues.

🧭 What You Can Do

• Stay active with balance and coordination exercises
• Challenge your brain with tasks involving movement and memory
• Seek a vestibular assessment if you or a loved one notice changes in balance, memory, or spatial awareness
