Epilepsia del lóbulo temporal de inicio tardío en etapa post-Covid. Post-Covid Late onset temporal lobe epilepsy.

Introduction: Temporal lobe epilepsy (TLE) of is the most frequent form of adult epilepsy, temporal mesial sclerosis (TMS) is a common abnormality associated. It could appear at the end of second decades in life.

Case report: We report a male patient, 67 years old, who suffered moderated Covid 19. Six months, he started with seizures which characterized by gastric disturbances, hand and oral automatisms, teeth snapping, upper extremities rigidity and change of hands coloration. EEG showed interictal paroxystic activity over left frontal and central-temporal regions and also abnormalities in quantitative measures. MRI described frontal, parietal, occipital and temporal mesial atrophy with hyperintensity on mesial and hippocampal areas. The volumetric value was diminished on middle frontal and temporal gyrus, pre-central gyrus, parietal lobe, insular cortex and operculum, the value of cortical thickness was diminished on pre-central gyrus.

Conclusions: This is a case with unusual beginning of TLE due to TME post-Covid.

Intoxicación por Monóxido de Carbono, Presentación de un Caso.

A 35-year-old patient experienced 2 months, low levels of carbon monoxide exposure, produced by the motor of his vehicle. He experienced drowsiness in the morning. Because of drowsiness he had an automotomobile accident with traumatic brain injury. The only symptom at the time of neurological examination was anterograde amnesia. The magnetic resonance (MRI) of the brain revealed bilateral necrosis of the globus pallidus. We present this case for prevention of carbon monoxide poisoning and as an example of the utility of MRI and neuropsychological examinations in detecting central nervous system dysfunction secondary to CO exposure.
