Key result
Chronic orthostatic intolerance symptoms warrant autonomic and neurodegenerative evaluation even without objective orthostatic hypotension.
Why the study?
Orthostatic dizziness and lightheadedness are frequent in patients aged 60 and above with diverse etiologies, requiring comprehensive evaluation to identify autonomic dysfunction and neurodegenerative disorders.
Subjective reports of orthostatic dizziness in older adults are clinically significant and warrant comprehensive autonomic and neurologic evaluation, even in the absence of objective orthostatic hypotension.
May warrant autonomic evaluation in symptomatic patients without hypotension; leaves open need for prospective validation.
Orthostatic dizziness and lightheadedness are frequent complaints in patients age 60 and above, whereas various common and uncommon etiologies need to be considered, including medication side effects, cardiovascular and metabolic causes and neurologic disorders. Autonomic dysfunction is a common etiology that warrants comprehensive medical and neurologic evaluations for identification of neurogenic orthostatic hypotension, prodromal Parkinson's disease, Lew body dementia, pure autonomic failure and others. In this article, key historical details, physical exam findings and diagnostic investigations for orthostatic dizziness are discussed. Patients' report of chronic and persistent orthostatic intolerance, even in the absence of objective orthostatic hypotension, should serve as a reliable and sufficient key feature should prompt an evaluation for autonomic and neurodegenerative disorders.

Svetlana Blitshteyn (2026) conducted a review in Orthostatic dizziness and lightheadedness. Comprehensive medical and neurologic evaluation was evaluated. Patient reports of chronic orthostatic intolerance should prompt evaluation for autonomic and neurodegenerative disorders, even in the absence of objective orthostatic hypotension.
