Altered sense of smell
False sensory perception in the ictal and post-ictal phase is also a notable feature of epilepsy. Most physicians group it with the aura phase of seizures. A lot of sensory perception is altered. This may result in auditory and visual hallucinations. Though less common, olfactory hallucinations do occur. The patients may smell something rancid, burning, chemical or sweet. The presentation is only short-lived, and the patient recovers soon after the spell.
