错把“耳石症”当中风，一招复位搞定眩晕

Core Viewpoint - The article discusses the common condition known as Benign Paroxysmal Positional Vertigo (BPPV), often mistaken for a stroke, highlighting its symptoms, causes, and treatment options [2][3]. Summary by Sections Symptoms and Diagnosis - Patients may experience sudden dizziness when changing head positions, often leading to concerns about serious conditions like stroke. A case study illustrates a patient who, after ruling out central nervous system issues, was diagnosed with BPPV [2]. - BPPV is characterized by brief episodes of vertigo triggered by specific head movements, lasting from a few seconds to a minute, and may be accompanied by nausea but not hearing loss [3][7]. Causes and Risk Factors - The condition is primarily caused by the displacement of calcium carbonate crystals (otoliths) in the inner ear, which disrupts balance perception [3]. - Age is a significant risk factor, with incidence increasing after 40 years, and women are 1.5 to 2 times more likely to be affected than men due to hormonal changes and bone metabolism issues [4]. - Lifestyle factors such as sleep deprivation, anxiety, and depression can also contribute to the risk of otolith displacement [4][5]. Treatment and Management - Diagnosis typically involves positional tests, and treatment may include specific maneuvers to reposition the displaced otoliths, which can lead to significant symptom relief [2]. - While BPPV is generally benign, it can severely impact daily life and may require medical intervention for recurrent cases [7].
