Some such symptoms that may accompany vertiginous epilepsy include:

Auditory hallucination
Cognitive impairment
Motor activity
Ictal behavior
Limbic aurasMany people tend to mistake dizziness as vertigo, and although they sound similar, dizziness is not considered a symptom of vertiginous epilepsy. Dizziness is the sensation of imbalance or floating, impending loss of consciousness, and/or confusion. This is different from vertigo which is characterized by the illusion of rotational movement  caused by the “conflict between the signals sent to the brain by balance- and position-sensing systems of the body”. Mechanism
Although a specific cause has not been identified to always induce vertiginous epilepsy there have been a number of supported hypotheses to how these seizures come about, the most common being traumatic injury to the head. Other causes include tumor or cancers in the brain, stroke with loss of blood flow to the brain, and infection. A less tested hypothesis that some believe may play a larger role in determining who is affected by this disease is a genetic mutation that predisposes the subject for vertiginous epilepsy. This hypothesis is supported by occurrences of vertiginous epilepsy in those with a family history of epilepsy. Vertiginous epilepsies are included in the category of the partial epilepsy in which abnormal electrical activity in the brain is localized. With current research, it is presumed that the most likely cause to produce vertigo are epilepsies occurring in the lateral temporal lobe. These abnormal electrical activities can either originate from within the temporal lobe or may propagate from an epilepsy in a neighboring region of the brain.
Epilepsies in the parietal and occipital lobes commonly propagate into the temporal lobe inducing a vertiginous state. This electrical propagation across the brain explains why so many different symptoms may be associated with the vertiginous seizure. The strength of the electrical signal and its direction of propagation in the brain will also determine which associated symptoms are noticeable. Diagnosis
The most important factor in diagnosing a patient with vertiginous epilepsy is the subject’s detailed description of the episode. However, due to the associated symptoms of the syndrome a subject may have difficulty remembering the specifics of the experience. This makes it difficult for a physician to confirm the diagnosis with absolute certainty. A questionnaire may be used to help patients, especially children, describe their symptoms. Clinicians may also consult family members for assistance in diagnosis, relying on their observations to help understand the episodes. In addition to the description of the event, neurological, physical and hematologic examinations are completed to assist in diagnosis. For proper diagnosis, an otological exam (examination of the ear) should also be completed to rule out disorders of the inner ear, which could also be responsible for manifestations of vertigo. This may include an audiological assessment and vestibular function test.
