Choreoathetosis- MedGen UID:
- 39313
- •Concept ID:
- C0085583
- •
- Disease or Syndrome
Involuntary movements characterized by both athetosis (inability to sustain muscles in a fixed position) and chorea (widespread jerky arrhythmic movements).
Focal impaired awareness seizure- MedGen UID:
- 543022
- •Concept ID:
- C0270834
- •
- Disease or Syndrome
Focal impaired awareness seizure (or focal seizure with impaired or lost awareness) is a type of focal-onset seizure characterized by some degree (which may be partial) of impairment of the person's awareness of themselves or their surroundings at any point during the seizure.
Tonic seizure- MedGen UID:
- 82855
- •Concept ID:
- C0270844
- •
- Disease or Syndrome
A tonic seizure is a type of motor seizure characterized by unilateral or bilateral limb stiffening or elevation, often with neck stiffening.
Atonic seizure- MedGen UID:
- 78735
- •Concept ID:
- C0270846
- •
- Disease or Syndrome
Atonic seizure is a type of motor seizure characterized by a sudden loss or diminution of muscle tone without apparent preceding myoclonic or tonic event lasting about 1 to 2 seconds, involving head, trunk, jaw, or limb musculature.
Bilateral tonic-clonic seizure- MedGen UID:
- 141670
- •Concept ID:
- C0494475
- •
- Sign or Symptom
A bilateral tonic-clonic seizure is a seizure defined by a tonic (bilateral increased tone, lasting seconds to minutes) and then a clonic (bilateral sustained rhythmic jerking) phase.
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.
Atypical absence seizure- MedGen UID:
- 108888
- •Concept ID:
- C0595948
- •
- Disease or Syndrome
An atypical absence seizure is a type of generalized non-motor (absence) seizure characterized 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.
Severe global developmental delay- MedGen UID:
- 332436
- •Concept ID:
- C1837397
- •
- Finding
A severe delay in the achievement of motor or mental milestones in the domains of development of a child.
Absent speech- MedGen UID:
- 340737
- •Concept ID:
- C1854882
- •
- Finding
Complete lack of development of speech and language abilities.
Infantile spasms- MedGen UID:
- 854616
- •Concept ID:
- C3887898
- •
- Disease or Syndrome
Infantile spasms represent a subset of "epileptic spasms". Infantile Spasms are epileptic spasms starting in the first year of life (infancy).
Delayed CNS myelination- MedGen UID:
- 867393
- •Concept ID:
- C4021758
- •
- Anatomical Abnormality
Delayed myelination in the central nervous system.
Myoclonic seizure- MedGen UID:
- 1385980
- •Concept ID:
- C4317123
- •
- Sign or Symptom
A myoclonic seizure is a type of motor seizure characterized by 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.
Typical absence seizure- MedGen UID:
- 1790454
- •Concept ID:
- C5551411
- •
- Disease or Syndrome
A typical absence seizure is a type of generalized non-motor (absence) seizure characterized by its sudden onset, interruption of ongoing activities, a blank stare, possibly a brief upward deviation of the eyes. Usually the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. Although not always available, an EEG would usually show 3 Hz generalized epileptiform discharges during the event.
Reduced cerebral white matter volume- MedGen UID:
- 1815057
- •Concept ID:
- C5706151
- •
- Finding
An abnormally low volume of the white matter of the brain.
Hypotonia- MedGen UID:
- 10133
- •Concept ID:
- C0026827
- •
- Finding
Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.
Nystagmus- MedGen UID:
- 45166
- •Concept ID:
- C0028738
- •
- Disease or Syndrome
Rhythmic, involuntary oscillations of one or both eyes related to abnormality in fixation, conjugate gaze, or vestibular mechanisms.
- Abnormality of the eye
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
