Balance Problems: Clinical Meaning

Parkinson's Disease

Parkinson's disease is a progressive neurological disorder affecting movement, caused by the loss of dopamine-producing neurons. Symptoms include tremor, rigidity, slowness of movement, and balance problems. There is no cure, but treatments can manage symptoms.

Alzheimer's Disease

Alzheimer's disease is the most common cause of dementia — a progressive neurological disorder that destroys memory and other cognitive functions. It typically begins with mild memory loss and progresses to severe cognitive impairment.

Stroke

A stroke occurs when blood supply to part of the brain is cut off (ischemic) or a blood vessel ruptures (hemorrhagic), causing brain cells to die. Fast action is critical — every minute matters. Use the FAST acronym: Face drooping, Arm weakness, Speech difficulty, Time to call emergency.

Multiple Sclerosis

Multiple sclerosis is a chronic autoimmune disease in which the immune system attacks the myelin sheath of nerve fibers in the central nervous system. It causes episodes of neurological symptoms including vision loss, muscle weakness, balance problems, and cognitive changes.

Guillain-Barré Syndrome

Guillain-Barré syndrome is an acute autoimmune polyneuropathy typically triggered by infection, causing rapidly ascending muscle weakness that can lead to respiratory paralysis. Most patients recover with immunotherapy (IVIG or plasmapheresis).

Peripheral Neuropathy

Peripheral neuropathy results from damage to peripheral nerves, causing numbness, tingling, burning pain, and weakness in the hands and feet. Diabetes, alcohol, vitamin B12 deficiency, and chemotherapy are common causes.

Essential Tremor

Essential tremor is the most common movement disorder, causing involuntary rhythmic shaking, most often affecting the hands during purposeful movement. It is distinct from Parkinson's tremor; propranolol and primidone are first-line treatments.

Normal Pressure Hydrocephalus

Normal pressure hydrocephalus presents with the classic triad of gait disturbance, urinary incontinence, and cognitive decline in older adults. It is caused by abnormal CSF accumulation and can be treated with ventricular shunting.

BPPV (Benign Paroxysmal Positional Vertigo)

BPPV is the most common cause of vertigo, caused by displaced calcium crystals in the inner ear. It causes brief but intense vertigo triggered by head position changes, treatable with repositioning maneuvers.

Labyrinthitis

Labyrinthitis is inflammation of the inner ear labyrinth, typically following a viral infection. It causes sudden severe vertigo, hearing loss, and tinnitus, significantly impacting daily functioning.

Chronic Vertigo

Chronic vertigo encompasses multiple conditions causing persistent or recurrent episodes of dizziness and spinning sensation. Common causes include BPPV, Meniere's disease, vestibular migraine, and labyrinthitis.
