"What Are the Causes of Dizziness in Cerebral Infarction?"

Cerebral Infarction (Ischemic Stroke)

Cerebral infarction, generally referring to ischemic stroke, often entails various causes for dizziness, including increased intracranial pressure and vestibular dysfunction. It is crucial to seek medical attention promptly and follow the doctor's instructions for treatment.

I. Non-Disease Factors

1. Increased Intracranial Pressure: Cerebral infarction leads to necrosis of brain tissue, causing surrounding edema that compresses adjacent healthy tissue, elevating intracranial pressure and potentially resulting in cerebral hernia. This can manifest as headache, nausea, vomiting, and papilledema. Mannitol injection is administered as prescribed to lower intracranial pressure, and surgery may be necessary to alleviate symptoms.

2. Vestibular Dysfunction: If cerebral infarction occurs in the cerebellum or brainstem, it can disrupt balance and sensory functions, triggering symptoms of vertigo, such as dizziness and unsteady gait. Medications like Flunarizine Hydrochloride Capsules and Ginkgo Leaf Extract Tablets can be prescribed to alleviate these symptoms.

II. Disease Factors

Apart from the aforementioned conditions, diseases like cervical spondylosis, hypertension, hypotension, and anemia may also induce similar symptoms, necessitating careful differential diagnosis.

For instance, Cervical Spondylosis: Disc herniation stimulating sympathetic nerves or vertebral arteries can cause abnormal vasoconstriction in the head, leading to dizziness accompanied by numbness and pain in the upper limbs. Traction therapy can be employed to manage this condition.
