SNOMED CT Concept\Clinical finding (finding)\...

\Head finding (finding)\Finding of brain\Seizure\Seizure disorder\A disease of the brain characterized by an enduring predisposition to generate epileptic seizures.\A type of epilepsy with only focal onset epileptic seizures. Seizures can arise from a single location or multiple locations.\A group of epilepsies characterized by age-dependent occurrence of drug responsive focal seizures in otherwise normal children. Seizures are focal motor or sensory with or without impaired awareness and may evolve to bilateral tonic-clonic seizures. Remission usually occurs by puberty. Development and cognition are typically normal. Neurological examination is normal. No significant structural lesions of the brain are present, and presumed genetic factors have an important role. The electroencephalogram (EEG) background activity is normal. Seizure semiology and EEG features are specific for each of the syndromes included in this group.\A type of self-limited focal epilepsy with onset typically between day two and seven of life. Seizures are focal tonic at onset, affecting the head, face, and limbs. Focal clonic or tonic seizures may evolve to bilateral tonic or clonic seizures. Onset may alternate between hemispheres. Autonomic features (apnea and cyanosis) are present in one third of seizures and may be the predominant manifestation. Seizure semiology may progress in a sequential pattern with tonic, clonic, myoclonic and autonomic features following each other without a single predominant feature. Clusters of seizures may occur over hours or days with the neonate behaving normally between events. Developmental progress is usually normal. The electroencephalogram (EEG) background is normal or has minor nonspecific abnormalities. Focal interictal epileptiform abnormalities can be seen in the central, centrotemporal or frontotemporal regions. MRI is normal or has nonspecific findings. Pathogenic variants are seen in KCNQ2, KCNQ3 and SCN2A.\A familial type of self-limited focal epilepsy with onset typically between day two and seven of life.

A familial type of self-limited focal epilepsy with onset typically between day two and seven of life. Seizures are focal tonic at onset, affecting the head, face, and limbs. Focal clonic or tonic seizures may evolve to bilateral tonic or clonic seizures. Onset may alternate between hemispheres. Autonomic features (apnea and cyanosis) can be seen. Seizure semiology may progress in a sequential pattern with tonic, clonic, myoclonic and autonomic features following each other without a single predominant feature. Clusters of seizures can occur over hours or days with the neonate behaving normally between events. Developmental progress is usually normal. The electroencephalogram (EEG) background is normal or has minor nonspecific abnormalities. Focal interictal epileptiform abnormalities can be seen in the central, centrotemporal or frontotemporal regions. MRI is normal or has nonspecific findings. Pathogenic variants are seen in KCNQ2, KCNQ3 and SCN2A.
