Gastroesophageal reflux- MedGen UID:
- 1368658
- •Concept ID:
- C4317146
- •
- Finding
A condition in which the stomach contents leak backwards from the stomach into the esophagus through the lower esophageal sphincter.
Seizure- MedGen UID:
- 20693
- •Concept ID:
- C0036572
- •
- Sign or Symptom
A seizure is an intermittent abnormality of nervous system physiology characterized by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
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.
Hyperreflexia- MedGen UID:
- 57738
- •Concept ID:
- C0151889
- •
- Finding
Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.
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.
Spastic tetraplegia- MedGen UID:
- 98433
- •Concept ID:
- C0426970
- •
- Disease or Syndrome
Spastic paralysis affecting all four limbs.
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.
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).
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.
Intellectual disability, profound- MedGen UID:
- 892508
- •Concept ID:
- C3161330
- •
- Mental or Behavioral Dysfunction
Profound mental retardation is defined as an intelligence quotient (IQ) below 20.
Atrophy/Degeneration affecting the brainstem- MedGen UID:
- 870454
- •Concept ID:
- C4024900
- •
- Disease or Syndrome
CNS hypomyelination- MedGen UID:
- 892446
- •Concept ID:
- C4025616
- •
- Finding
Reduced amount of myelin in the central nervous system resulting from defective myelinogenesis.
Cerebral cortical atrophy- MedGen UID:
- 1646740
- •Concept ID:
- C4551583
- •
- Disease or Syndrome
Atrophy of the cortex of the cerebrum.
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.
Progressive microcephaly- MedGen UID:
- 340542
- •Concept ID:
- C1850456
- •
- Anatomical Abnormality
Progressive microcephaly is diagnosed when the head circumference falls progressively behind age- and gender-dependent norms.
Generalized hypotonia- MedGen UID:
- 346841
- •Concept ID:
- C1858120
- •
- Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Microcephaly- MedGen UID:
- 1644158
- •Concept ID:
- C4551563
- •
- Finding
Head circumference below 2 standard deviations below the mean for age and gender.
