Seizure- MedGen UID:
- 20693
- •Concept ID:
- C0036572
- •
- Sign or Symptom
A seizure is an intermittent abnormality of nervous system physiology characterised by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
Hypoplasia of the corpus callosum- MedGen UID:
- 138005
- •Concept ID:
- C0344482
- •
- Congenital Abnormality
Underdevelopment of the corpus callosum.
Epileptic encephalopathy- MedGen UID:
- 452596
- •Concept ID:
- C0543888
- •
- Disease or Syndrome
A condition in which epileptiform abnormalities are believed to contribute to the progressive disturbance in cerebral function. Epileptic encephalaopathy is characterized by (1) electrographic EEG paroxysmal activity that is often aggressive, (2) seizures that are usually multiform and intractable, (3) cognitive, behavioral and neurological deficits that may be relentless, and (4) sometimes early death.
Global developmental delay- MedGen UID:
- 107838
- •Concept ID:
- C0557874
- •
- Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
Atypical absence seizure- MedGen UID:
- 108888
- •Concept ID:
- C0595948
- •
- Disease or Syndrome
An atypical absence seizure is a type of generalised non-motor (absence) seizure characterised by interruption of ongoing activities and reduced responsiveness. In comparison to a typical absence seizure, changes in tone may be more pronounced, onset and/or cessation may be less abrupt, and the duration of the ictus and post-ictal recovery may be longer. Although not always available, an EEG often demonstrates slow (<3 Hz), irregular, generalized spike-wave activity.
Hypsarrhythmia- MedGen UID:
- 195766
- •Concept ID:
- C0684276
- •
- Finding
Hypsarrhythmia is abnormal interictal high amplitude waves and a background of irregular spikes. There is continuous (during wakefulness), high-amplitude (>200 Hz), generalized polymorphic slowing with no organized background and multifocal spikes demonstrated by electroencephalography (EEG).
Developmental regression- MedGen UID:
- 324613
- •Concept ID:
- C1836830
- •
- Disease or Syndrome
Loss of developmental skills, as manifested by loss of developmental milestones.
Generalized myoclonic seizure- MedGen UID:
- 892704
- •Concept ID:
- C4021759
- •
- Disease or Syndrome
A generalized myoclonic seizure is a type of generalized motor seizure characterised by bilateral, sudden, brief (<100 ms) involuntary single or multiple contraction of muscles or muscle groups of variable topography (axial, proximal limb, distal). Myoclonus is less regularly repetitive and less sustained than is clonus.
Generalized hypotonia- MedGen UID:
- 346841
- •Concept ID:
- C1858120
- •
- Finding
Generalized muscular hypotonia (abnormally low muscle tone).
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
