Common Causes of Dizziness: Neurological, Otolaryngological, Cardiological, and Psychological Factors
Dizziness is a frequent complaint, affecting up to 35% of people at some point, and can arise from a wide range of causes. These include neurological (such as central nervous system disorders), otolaryngological (inner ear or vestibular system problems), metabolic, cardiological (heart and blood vessel issues), and psychological factors (like anxiety or depression) Woźniak2025Karataş2008Staab2006+1 MORE. Dizziness can be described as a spinning sensation (vertigo), unsteadiness, or lightheadedness, and may be accompanied by symptoms like nausea or vomiting depending on the underlying cause Woźniak2025Karataş2008.
Peripheral and Central Causes of Dizziness
Dizziness is often categorized as either peripheral or central, based on where the problem originates. Peripheral causes are usually related to the inner ear or vestibular system, such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis, Meniere’s disease, and vestibular migraine Woźniak2025Karataş2008Turner2020+1 MORE. Central causes involve the brainstem or cerebellum and include cerebrovascular disorders (like strokes in the vertebrobasilar circulation), migraine, multiple sclerosis, tumors, neurodegenerative diseases, and side effects from certain drugs Karataş2008Haidar2020. Psychiatric disorders can also present as dizziness, especially in the form of chronic subjective dizziness or psychophysiologic dizziness Karataş2008Staab2006.
Cardiovascular and Drug-Related Causes, Especially in the Elderly
In elderly patients, cardiovascular disease is a leading cause of dizziness, often presenting as presyncope (a feeling of near-fainting) . Other common causes in this age group include peripheral vestibular disease, psychiatric illness, and adverse drug effects, with many elderly patients experiencing more than one contributing factor at the same time Maarsingh2010Jahn2019Iwasaki2015. Medications, especially sedatives and antihypertensives, can also contribute significantly to dizziness in older adults .
Age-Specific Causes: Children, Adolescents, and the Elderly
The causes of dizziness can vary by age. In children, benign paroxysmal vertigo of childhood (BPVC) and vestibular migraine are most common, while in adolescents, vestibular migraine becomes more prevalent, with some cases of Meniere’s disease and cardiogenic vertigo also appearing . In the elderly, age-related decline in vestibular function, sensory deficits, polyneuropathy, impaired vision, and sarcopenia (loss of muscle mass) are frequent contributors Jahn2019Iwasaki2015.
Psychiatric and Multifactorial Causes
Psychiatric conditions, such as anxiety, depression, and panic disorder, are recognized contributors to dizziness, either as primary causes or as factors that worsen symptoms from other medical conditions Karataş2008Staab2006. Chronic subjective dizziness is a common presentation at the intersection of psychiatric and neuro-otologic disorders . Many patients, especially the elderly, have multiple overlapping causes for their dizziness, making diagnosis and management more complex Maarsingh2010Jahn2019.
Conclusion
Dizziness is a complex symptom with many possible causes, including inner ear disorders, brain and nerve conditions, heart and blood vessel problems, medication side effects, and psychological factors. The most common causes vary by age group, with cardiovascular and drug-related causes more prominent in the elderly, and vestibular disorders and migraines more common in younger people. Accurate diagnosis relies on a thorough medical history, physical examination, and sometimes specialized tests, as effective treatment depends on identifying the underlying cause Woźniak2025Karataş2008Maarsingh2010+6 MORE.
