Which condition is described as a sensation of dizziness or "room spinning"?

The sensation described as dizziness or "room spinning" is known as vertigo. Vertigo is specifically characterized by the false feeling that you or your surroundings are moving or spinning. This condition often results from issues in the inner ear or the vestibular system, which is responsible for balance. Individuals experiencing vertigo may feel a strong, unsettling sensation that can be quite disorienting and may even lead to nausea or difficulty walking.

In contrast, syncope refers to a temporary loss of consciousness due to a drop in blood flow to the brain, often described as fainting. Dizziness is a more general term that encompasses a range of feelings, including lightheadedness or unsteadiness, but does not specifically refer to the spinning sensation. Presyncope describes a feeling of lightheadedness or impending faintness, often a precursor to syncope. Therefore, vertigo is the accurate term for the specific sensation of spinning described in the question.
