Benign Paroxysmal Positional Vertigo (BPPV): This condition is characterized by brief, intense episodes of vertigo triggered by specific head movements. It's a common cause of vertigo and often presents with a normal head examination, making it a likely diagnosis for normal head reeling.

Vestibular Migraine: A condition that involves vertigo, often without headache, and can be triggered by various factors including position changes. It's a common cause of episodic vertigo.
Labyrinthitis: An inner ear disorder characterized by inflammation of the labyrinth, which can cause vertigo, hearing loss, and tinnitus. The symptoms can vary, and some cases might present with normal head examination findings.
Inner Ear Infection: Infections like viral or bacterial labyrinthitis can cause vertigo. While some may present with systemic signs of infection, others might have a more subtle presentation.

Posterior Circulation Stroke: Although less common, a stroke in the posterior circulation can present with vertigo as a primary symptom. It's crucial to rule out this condition due to its severe implications and the need for urgent treatment.
Multiple Sclerosis: In rare cases, multiple sclerosis can present with vertigo as an initial symptom due to central nervous system demyelination affecting the brainstem or cerebellum.
Acoustic Neuroma: A benign tumor on the nerve connecting the inner ear to the brain can cause vertigo, among other symptoms like hearing loss and tinnitus. Early detection is important for treatment planning.

Meniere's Disease: A disorder of the inner ear that causes episodes of vertigo, ringing in the ears (tinnitus), hearing loss, and a feeling of fullness in the ear. It's less common than other causes of vertigo but should be considered in the differential diagnosis.
Mal de Debarquement Syndrome: A rare condition that occurs after a period of exposure to motion, like being on a boat, and is characterized by a feeling of swaying or rocking that persists after the motion has stopped.
