Absence seizures are often associated with impaired or loss of consciousness clinically proved to have an impact on motor and cognitive abnormalities of the nerve cells of the brain. Seizure admits several etiopathophysiological events leading to several neurofunctional changes in the reticulothalamocortical circuitry zones of the central nervous system. This paves the episodes of absence seizure events. A clinical case report of absence seizure in a 25 years age adult patient came to the hospital with impaired consciousness. The brain magnetic resonance imaging scanning of the patient detected a small focal flair hypertensive area in the right parasellar region close to cavernous sinus with mild flair hypersensitivity in the left cavernous sinuses, right maxillary, and ethmoid sinusitis. The electroencephalogram of the brain showed normal waves with electrode artifacts was observed. The patient was confirmed with absence seizures, and he was treated with oxcarbazepine 150 mg twice daily. The patient was recovered from seizure and discharged with medications. He was called for follow-up examination once in 3-month period.
