Key causes of someone falling like this include neurological conditions like Parkinson's disease (specifically retropulsion or postural instability), normal pressure hydrocephalus, or backward disequilibrium. Other factors include inner ear dysfunction (vertigo), low blood pressure (orthostatic hypotension), or medication side effects. Specific Causes for Backward Falls: • Parkinson’s Disease (Retropulsion): Involuntary, quick, small steps backward, often accompanied by rigid muscles and a tendency to tilt backward. • Backward Disequilibrium: A common condition in the elderly where the body’s center of mass shifts backward, causing loss of balance. • Neurological Damage: Damage to the cerebellum or occipital lobe, or brain disorders like Normal Pressure Hydrocephalus, can cause an instinctual leaning or stepping backward. • Drop Attacks: Sudden loss of postural tone without warning, which can cause an abrupt collapse, sometimes backward. • Functional Neurological Disorder (FND): A type of functional, non-epileptic, or psychological reaction that can manifest as a sudden, unexplained fall. • Vestibular (Inner Ear) Dysfunction: A severe spinning sensation (vertigo) can cause someone to lose their balance and fall. • Muscular/Skeletal Issues: Weakness in the legs or forward-leaning muscles can cause a person to fall backward. If these events occur, they should be investigated by a doctor to determine the underlying neurological, vestibular, or cardiac cause
