Hi there. Various causes of balance loss abnormalities are due to visual, vestibular and somatosensory deficits in the brain like cataracts, glaucoma, acoustic neuroma, spinal cord injury, stroke, brain trauma, multiple sclerosis, parkinson’s or cerebellar ataxia, musculoskeletal problems.
.diagnosis would require a physical therapy diagnosis to assess cognition, cranial and peripheral nerves, muscle strength, posture, reflexes, etc. Treatment would be relevant to the diagnosis of cause. Take care.
