What causes dizziness and the sensation that objects are spinning?

Dizziness is a common functional disorder of the brain and one of the most frequent clinical symptoms. It manifests as sensations such as lightheadedness, head fullness or pressure, unsteadiness (a “light-headed” or “floating” feeling), a sensation of internal head movement or swaying, and blurred or dimmed vision. But what causes dizziness accompanied by a spinning visual sensation? Below, we address this question.

What Causes Dizziness Accompanied by a Spinning Visual Sensation?

Numerous underlying conditions can cause dizziness and vertigo (a sensation of spinning). For instance, patients with cervical spine disorders may experience vertigo—often described as “the room spinning”—if they adopt improper postures during daily activities. This typically results from degenerative changes in the cervical joints, leading to compression of adjacent nerves and blood vessels. Such compression impairs cerebral blood flow, causing cerebral hypoperfusion and hypoxia, which in turn trigger dizziness and a spinning visual sensation. In severe cases, patients may also develop headache, nausea, vomiting, numbness in the arms, or tingling in the fingers. Alternatively, hypertension may be the underlying cause.

In hypertensive patients, emotional stress or excessive psychological pressure can provoke acute blood pressure elevation, resulting in dizziness and vertigo. Similarly, cerebrovascular disease—including atherosclerosis, arterial wall thickening, and luminal narrowing—can compromise cerebral perfusion, leading to cerebral ischemia and hypoxia. Consequently, patients may experience dizziness, rotational visual disturbances, and generalized fatigue; severe cases may involve vomiting and headache. Therefore, it is strongly recommended that patients seek evaluation at a reputable hospital. Diagnostic workup may include cranial CT, cervical CT, and routine blood tests to identify the precise etiology. Once diagnosed, patients should follow their physician’s recommendations and actively adhere to prescribed treatment.

The above outlines potential causes of dizziness accompanied by a spinning visual sensation. We hope this information is helpful to you.
