What causes balance problems
Balance is maintained by the integration of vestibular (inner ear), visual, proprioceptive (joint position sense), cardiovascular and cerebellar systems. Dysfunction in any domain produces unsteadiness. Vestibular causes include BPPV (positional unsteadiness), vestibular neuritis (acute imbalance with spinning), vestibular migraine (fluctuating unsteadiness with headache history) and bilateral vestibular loss (oscillopsia and unsteadiness in dark environments). Neurological causes include peripheral neuropathy (reduced proprioception from feet), cerebellar ataxia (wide-based gait, midline instability), Parkinson's disease (postural instability, festinating gait) and stroke.
Cardiovascular causes include orthostatic hypotension (unsteadiness on standing, relieved by sitting) and cardiac arrhythmias. Musculoskeletal causes include lower limb weakness, joint stiffness and pain. Falls in older adults are multifactorial — identifying and addressing each contributing domain reduces recurrence. A systematic approach avoids attributing balance problems to a single cause when multiple domains are involved.
- Vestibular — BPPV, vestibular neuritis, vestibular migraine, bilateral loss
- Neurological — neuropathy, cerebellar ataxia, Parkinson's disease
- Cardiovascular — orthostatic hypotension, arrhythmia
- Musculoskeletal — weakness, joint stiffness, pain

Evaluation approach
Evaluation maps the onset, duration, triggers (position change, standing, walking, dark environments) and associated features (spinning, nausea, hearing change, weakness, numbness, urgency). Timed Up and Go (TUG) test and Romberg test quantify balance impairment. Neurological examination includes gait assessment, cerebellar testing, proprioception, reflexes, motor power and orthostatic blood pressure measurement.
Vestibular assessment includes positional testing (Dix-Hallpike for BPPV), head impulse testing and dynamic visual acuity where available. Blood tests may include glucose, B12, thyroid function and haemoglobin to exclude reversible contributors. Imaging is considered when neurological signs suggest central causes. Management addresses each identified domain — vestibular rehabilitation for vestibular dysfunction, physiotherapy for musculoskeletal weakness, medication review for orthostatic hypotension, and neurological management for central causes.
- Timed Up and Go and Romberg tests — quantify balance impairment
- Positional testing — Dix-Hallpike for BPPV
- Orthostatic blood pressure — identify cardiovascular contribution
- Targeted management for each identified domain
