Dysarthria- MedGen UID:
- 8510
- •Concept ID:
- C0013362
- •
- Mental or Behavioral Dysfunction
Dysarthric speech is a general description referring to a neurological speech disorder characterized by poor articulation. Depending on the involved neurological structures, dysarthria may be further classified as spastic, flaccid, ataxic, hyperkinetic and hypokinetic, or mixed.
Leukodystrophy- MedGen UID:
- 6070
- •Concept ID:
- C0023520
- •
- Disease or Syndrome
Leukodystrophy refers to deterioration of white matter of the brain resulting from degeneration of myelin sheaths in the CNS. Their basic defect is directly related to the synthesis and maintenance of myelin membranes. Symmetric white matter involvement at MRI is a typical finding in patients with leukodystrophies.
Spastic diplegia- MedGen UID:
- 44181
- •Concept ID:
- C0023882
- •
- Disease or Syndrome
Spasticity (neuromuscular hypertonia) primarily in the muscles of the legs, hips, and pelvis.
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.
Babinski sign- MedGen UID:
- 19708
- •Concept ID:
- C0034935
- •
- Finding
Upturning of the big toe (and sometimes fanning of the other toes) in response to stimulation of the sole of the foot. If the Babinski sign is present it can indicate damage to the corticospinal tract.
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.
Hyperreflexia- MedGen UID:
- 57738
- •Concept ID:
- C0151889
- •
- Finding
Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.
Abnormal pyramidal sign- MedGen UID:
- 68582
- •Concept ID:
- C0234132
- •
- Sign or Symptom
Functional neurological abnormalities related to dysfunction of the pyramidal tract.
Hypoplasia of the corpus callosum- MedGen UID:
- 138005
- •Concept ID:
- C0344482
- •
- Congenital Abnormality
Underdevelopment of the corpus callosum.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk.
Increased CSF lactate- MedGen UID:
- 257904
- •Concept ID:
- C1167918
- •
- Finding
Increased concentration of lactate in the cerebrospinal fluid.
Spastic ataxia- MedGen UID:
- 376528
- •Concept ID:
- C1849156
- •
- Disease or Syndrome
Increased CSF glycine concentration- MedGen UID:
- 1691638
- •Concept ID:
- C5139615
- •
- Finding
Abnormally increased levels of glycine in cerebrospinal fluid.
Hyperglycinemia- MedGen UID:
- 82817
- •Concept ID:
- C0268559
- •
- Disease or Syndrome
An elevated concentration of glycine in the blood.
Increased circulating lactate concentration- MedGen UID:
- 332209
- •Concept ID:
- C1836440
- •
- Finding
Abnormally increased level of blood lactate (2-hydroxypropanoic acid). Lactate is produced from pyruvate by lactate dehydrogenase during normal metabolism. The terms lactate and lactic acid are often used interchangeably but lactate (the component measured in blood) is strictly a weak base whereas lactic acid is the corresponding acid. Lactic acidosis is often used clinically to describe elevated lactate but should be reserved for cases where there is a corresponding acidosis (pH below 7.35).
Reduced tissue glycine cleavage enzyme activity- MedGen UID:
- 1053784
- •Concept ID:
- CN377977
- •
- Finding
Concentration or activity of the glycine cleavage enzyme below the lower limit of normal. This enzyme can be measured in multiple tissues including leukocytes and cultured fibroblasts.
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.
Optic atrophy- MedGen UID:
- 18180
- •Concept ID:
- C0029124
- •
- Disease or Syndrome
Atrophy of the optic nerve. Optic atrophy results from the death of the retinal ganglion cell axons that comprise the optic nerve and manifesting as a pale optic nerve on fundoscopy.
Strabismus- MedGen UID:
- 21337
- •Concept ID:
- C0038379
- •
- Disease or Syndrome
A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error.
Visual impairment- MedGen UID:
- 777085
- •Concept ID:
- C3665347
- •
- Finding
Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery.
Decreased activity of the pyruvate dehydrogenase complex- MedGen UID:
- 326605
- •Concept ID:
- C1839888
- •
- Finding
