Differential Diagnosis for Dizziness that Resolves with Laying Down

  • Single Most Likely Diagnosis
    • Benign Paroxysmal Positional Vertigo (BPPV): This condition is characterized by brief, episodic vertigo triggered by specific head movements, which can include standing up or changing positions. The symptoms often resolve when the individual lays down, as this position does not trigger the vertigo. BPPV is a common cause of vertigo and is typically benign.
  • Other Likely Diagnoses
    • Orthostatic Hypotension: This condition involves a significant drop in blood pressure when standing up, leading to dizziness or lightheadedness that improves upon laying down. It can be due to dehydration, medication side effects, or autonomic nervous system dysfunction.
    • Vestibular Migraine: Although not exclusively related to positional changes, vestibular migraines can cause vertigo and dizziness that may improve with rest or laying down. These migraines are a type of migraine headache that affects the vestibular system.
  • Do Not Miss Diagnoses
    • Cardiac Arrhythmias: Certain arrhythmias, such as atrial fibrillation or other rhythm disturbances, can cause dizziness or near-syncope that may improve when the individual lays down, due to increased cardiac output in the supine position. Missing this diagnosis could lead to serious cardiac complications.
    • Transient Ischemic Attack (TIA) or Stroke: While less common, TIAs or strokes can present with vertigo or dizziness, especially if the posterior circulation is involved. These conditions are medical emergencies and must be promptly identified and treated.
  • Rare Diagnoses
    • Meniere's Disease: An inner ear disorder that involves vertigo, hearing loss, and tinnitus. While vertigo in Meniere's can be severe and debilitating, it does not typically resolve simply by laying down.
    • Autoimmune Inner Ear Disease: A rare condition characterized by sudden hearing loss and vertigo, which can be constant or episodic. The vertigo may not have a clear positional component but can be severe and debilitating.
