Head CT Wedge shaped I'll defined hypodense focus is seen in the cortical subcortical region of the right parietal lobe. Underlying gyrus and sulci are effaced. Patchy hypodensities along the periventricular white matter of both frontal and parietal lobes are also noted. The rest of the grey-white matter interface is maintained. Initial Imaging Studies
CT Malacic changes CBC Hgb 138 Hct .42 WBC 8.5 N .72 L .24 M .04 PC 137 PT 12.2 INR 0.89 ALT 27.04 BUN 4.48 Creatinine 99.01 Na 137 K 3.9 Lipid Profile (results to follow) Initial Diagnostics
Initial Management • Phenytoin • Loading dose 1gm • Maintained at 100 mg/cap TID • Admit to ACSU • Cardiac, CBG monitoring • O2 Support, seizure precautions • Diazepam 5 mg IV • Ketorolac 30 mg IV then q8 prn for headache • Continue maintenance medications
Imaging Results • Cranial MRI • Wedge-shaped Right inferior parietal cortical-subcortical encephalomalacia, gliosis and siderosis, presumably sequelae of a previous water-shed type infarction with hemorrhagic conversion • Mild microvascular white matter ischemic changes on the left centrum semiovale • Mild central cerebral volume loss
Imaging Results • MRA: No aneurysm or any significant stenosis or vascular malformations seen • MRV: No evident cortical vein or dural sinus thrombosis
Diagnostics • ECG: Atrial Fibrillation, RVR • TFT: • TSH 3.01 uIU/mL • FT3 2 pg/mL • FT4 0.83 ng/dL • EEG: abnormal EEG due to a focal theta slowing on the right temporo-parietal occipital region with wave epileptiform discharges on the right temporo-occipital region consistent with a focal cerebral dysfunction and a tendency toward localization-related seizures at the right temporo-occipital region
Epileptogenesis • Transformation of a normal neuronal network into one that is chronically hyperexcitable • Trauma, stroke, or infection • Injury lowers the seizure threshold in the affected region
CVD is the number one cause of epilepsy in the elderly • Oxfordshire Stroke Community Project (OSCP) • 11.5% of patients with stroke are at risk of developing late-onset post-strokeseizures within 5 years • Naess and colleagues • 10.5% developed post-stroke seizure over mean follow up of 5.7 years. • Hart and colleagues • recurrence after a first seizure after stroke of 40% in 12 months
Early Onset Seizure Late Onset Seizure occurs after two weeks of stroke onset peak 6-12 months after stroke associated with the persistent changes in neuronal excitability and gliotic scarring • occurs w/in first two weeks • peak 24 hrs after stroke
Stroke severity Independently associated with the development of seizures after ischemic stroke (HR, 10; 95% CI, 1.16 to 3.82; P<0.02) Seizures and Epilepsy After Ischemic Stroke OsvaldoCamilo and Larry B. Goldstein, 2004 • Cortical location • Best-characterized risk factor for early seizures after ischemic stroke • Significant risk factor in the SASS study (HR, 2.09; 95% CI, 1.19 to 3.68; P<0. 01)
Management • Antiepileptic Drug Therapy • Goal: completely prevent seizures without causing untoward side effects • Treat the underlying conditions • Reverse the problem and prevent its recurrence
