1. A 35 year old woman presented to the neurology clinic for evaluation of her first onset seizure 1-week back. She was admitted in the hospital at the time and evaluated and all her metabolic parameters were found to be normal. Which of the following statements about this woman is false?
   
1. Neuroimaging with a MRI scan is essential as it clinches the diagnosis in 70% of patients.
2. Neuroimaging is unlikely to show a stroke
3. Neuroimaging is most likely to show vascular abnormalities.
4. Incidence of brain tumors causing such seizures is about 2%.

Answer: The correct answer is (a). In young to middle-aged adults, common MRI findings are mesial temporal sclerosis, sequelae of head injury, congenital anomalies, brain tumors, and vascular lesions. In the elderly, MRIs often reveal strokes, cerebral degeneration, or neoplasms. However, up to 50 percent of patients, regardless of age, have normal neuroimaging studies.
