Presentation
Pathophysiology Any lesion affecting the central vestibular apparatus will present with vertigo as the main presenting symptom. [ncbi.nlm.nih.gov]
Cardiovascular
- Hypertension
Thrombolytic therapy should be considered if the patient is suffering from an acute posterior circulation ischemic stroke within 3 to 4.5 hours of onset, although it is critical to be aware of any contraindications (e.g., recent surgery, severe hypertension [ncbi.nlm.nih.gov]
Neurologic
- Dysarthria
A stroke in the brain can trigger not only vertigo but dysarthria (slurred speech), ataxia (problems moving), weakness, and numbness/tingling. You should get emergency help right away. [webmd.com]
[…] posture, any tinnitus or hearing impairment, any previous episodes, any sick contact, any fever, any skin rash, vascular risk factors, medications and dosage, any headache, and lastly any brainstem symptoms including weakness, numbness, diplopia or dysarthria [ncbi.nlm.nih.gov]
Treatment
There are drugs and other treatments for both types. Finding out which one you've got -- and what's causing it -- can help you and your doctor decide how to manage it. [webmd.com]
Once a diagnosis of central vertigo has been established, treatment is aimed at the underlying cause. [ncbi.nlm.nih.gov]
Prognosis
Prognosis The prognosis of central vertigo depends on the underlying cause. The most common is acute lateral medullary syndrome due to occlusion of the vertebral artery or the posterior inferior cerebellar artery. [ncbi.nlm.nih.gov]
Etiology
Etiology Central vertigo occurs when there is any lesion or dysfunction of the brainstem vestibular apparatus as described above. [ncbi.nlm.nih.gov]
Epidemiology
Other less common causes include infection, trauma, posterior fossa brain tumors, and migraine.[2] Epidemiology In the United States, approximately 800,000 individuals per year experience a stroke. Of these, about 85% are ischemic. [ncbi.nlm.nih.gov]
