Athetosis- MedGen UID:
- 2115
- •Concept ID:
- C0004158
- •
- Disease or Syndrome
A slow, continuous, involuntary writhing movement that prevents maintenance of a stable posture. Athetosis involves continuous smooth movements that appear random and are not composed of recognizable sub-movements or movement fragments. In contrast to chorea, in athetosis, the same regions of the body are repeatedly involved. Athetosis may worsen with attempts at movement of posture, but athetosis can also occur at rest.
Chorea- MedGen UID:
- 3420
- •Concept ID:
- C0008489
- •
- Disease or Syndrome
Chorea (Greek for 'dance') refers to widespread arrhythmic involuntary movements of a forcible, jerky and restless fashion. It is a random-appearing sequence of one or more discrete involuntary movements or movement fragments. Movements appear random because of variability in timing, duration or location. Each movement may have a distinct start and end. However, movements may be strung together and thus may appear to flow randomly from one muscle group to another. Chorea can involve the trunk, neck, face, tongue, and extremities.
Dystonic disorder- MedGen UID:
- 3940
- •Concept ID:
- C0013421
- •
- Sign or Symptom
An abnormally increased muscular tone that causes fixed abnormal postures. There is a slow, intermittent twisting motion that leads to exaggerated turning and posture of the extremities and trunk.
Cerebral atrophy- MedGen UID:
- 116012
- •Concept ID:
- C0235946
- •
- Disease or Syndrome
Atrophy (wasting, decrease in size of cells or tissue) affecting the cerebrum.
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.
Inability to walk- MedGen UID:
- 107860
- •Concept ID:
- C0560046
- •
- Finding
Incapability to ambulate.
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).
Focal tonic seizure- MedGen UID:
- 199867
- •Concept ID:
- C0752324
- •
- Disease or Syndrome
A type of focal motor seizure characterized by sustained increase in muscle contraction, lasting a few seconds to minutes.
Generalized tonic seizure- MedGen UID:
- 322935
- •Concept ID:
- C1836508
- •
- Disease or Syndrome
A generalized tonic seizure is a type of generalized motor seizure characterized by bilateral limb stiffening or elevation, often with neck stiffening without a subsequent clonic phase. The tonic activity can be a sustained abnormal posture, either in extension or flexion, sometimes accompanied by tremor of the extremities.
Absent speech- MedGen UID:
- 340737
- •Concept ID:
- C1854882
- •
- Finding
Complete lack of development of speech and language abilities.
EEG with burst suppression- MedGen UID:
- 369943
- •Concept ID:
- C1969156
- •
- Finding
The burst suppression pattern in electroencephalography refers to a characteristic periodic pattern of low voltage (<10 microvolts) suppressed background and a relatively shorter pattern of higher amplitude slow, sharp, and spiking complexes.
Delayed CNS myelination- MedGen UID:
- 867393
- •Concept ID:
- C4021758
- •
- Anatomical Abnormality
Delayed myelination in the central nervous system.
- Abnormality of the nervous system
