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.
Spasticity- MedGen UID:
- 7753
- •Concept ID:
- C0026838
- •
- Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
Myoclonus- MedGen UID:
- 10234
- •Concept ID:
- C0027066
- •
- Finding
Very brief, involuntary random muscular contractions occurring at rest, in response to sensory stimuli, or accompanying voluntary movements.
Intellectual disability, severe- MedGen UID:
- 48638
- •Concept ID:
- C0036857
- •
- Mental or Behavioral Dysfunction
Severe mental retardation is defined as an intelligence quotient (IQ) in the range of 20-34.
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).
Hypokinesia- MedGen UID:
- 39223
- •Concept ID:
- C0086439
- •
- Finding
Abnormally diminished motor activity. In contrast to paralysis, hypokinesia is not characterized by a lack of motor strength, but rather by a poverty of movement. The typical habitual movements (e.g., folding the arms, crossing the legs) are reduced in frequency.
Cerebral atrophy- MedGen UID:
- 116012
- •Concept ID:
- C0235946
- •
- Disease or Syndrome
Atrophy (wasting, decrease in size of cells or tissue) affecting the cerebrum.
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.
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.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk.
Cerebellar atrophy- MedGen UID:
- 196624
- •Concept ID:
- C0740279
- •
- Disease or Syndrome
Cerebellar atrophy is defined as a cerebellum with initially normal structures, in a posterior fossa with normal size, which displays enlarged fissures (interfolial spaces) in comparison to the foliae secondary to loss of tissue. Cerebellar atrophy implies irreversible loss of tissue and result from an ongoing progressive disease until a final stage is reached or a single injury, e.g. an intoxication or infectious event.
Developmental regression- MedGen UID:
- 324613
- •Concept ID:
- C1836830
- •
- Disease or Syndrome
Loss of developmental skills, as manifested by loss of developmental milestones.
Focal hemiclonic seizure- MedGen UID:
- 335477
- •Concept ID:
- C1846620
- •
- Disease or Syndrome
A type of focal clonic seizure characterized by sustained rhythmic jerking rapidly involves one side of the body at seizure onset.
Absent speech- MedGen UID:
- 340737
- •Concept ID:
- C1854882
- •
- Finding
Complete lack of development of speech and language abilities.
Multifocal seizures- MedGen UID:
- 482664
- •Concept ID:
- C3281034
- •
- Finding
Seizures that start from several different areas of the brain (i.e., with multiple ictal onset locations).
Hyperkinetic movements- MedGen UID:
- 854367
- •Concept ID:
- C3887506
- •
- Disease or Syndrome
Motor hyperactivity with excessive movement of muscles of the body as a whole.
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.
Rigidity- MedGen UID:
- 7752
- •Concept ID:
- C0026837
- •
- Sign or Symptom
Continuous involuntary sustained muscle contraction. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from muscle spasticity.
Cogwheel rigidity- MedGen UID:
- 57469
- •Concept ID:
- C0151564
- •
- Sign or Symptom
A type of rigidity in which a muscle responds with cogwheellike jerks to the use of constant force in bending the limb (i.e., it gives way in little, repeated jerks when the muscle is passively stretched).
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
