Sensorineural hearing loss disorder- MedGen UID:
- 9164
- •Concept ID:
- C0018784
- •
- Disease or Syndrome
A type of hearing impairment in one or both ears related to an abnormal functionality of the cochlear nerve.
Hearing impairment- MedGen UID:
- 235586
- •Concept ID:
- C1384666
- •
- Disease or Syndrome
A decreased magnitude of the sensory perception of sound.
Profound sensorineural hearing impairment- MedGen UID:
- 868926
- •Concept ID:
- C4023338
- •
- Disease or Syndrome
Complete loss of hearing related to a sensorineural defect.
Cerebellar ataxia- MedGen UID:
- 849
- •Concept ID:
- C0007758
- •
- Disease or Syndrome
Cerebellar ataxia refers to ataxia due to dysfunction of the cerebellum. This causes a variety of elementary neurological deficits including asynergy (lack of coordination between muscles, limbs and joints), dysmetria (lack of ability to judge distances that can lead to under- or overshoot in grasping movements), and dysdiadochokinesia (inability to perform rapid movements requiring antagonizing muscle groups to be switched on and off repeatedly).
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.
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.
Abnormal pyramidal sign- MedGen UID:
- 68582
- •Concept ID:
- C0234132
- •
- Sign or Symptom
Functional neurological abnormalities related to dysfunction of the pyramidal tract.
Mental deterioration- MedGen UID:
- 66713
- •Concept ID:
- C0234985
- •
- Mental or Behavioral Dysfunction
Loss of previously present mental abilities, generally in adults.
Cognitive impairment- MedGen UID:
- 90932
- •Concept ID:
- C0338656
- •
- Mental or Behavioral Dysfunction
Abnormal cognition is characterized by deficits in thinking, reasoning, or remembering.
Peripheral axonal neuropathy- MedGen UID:
- 266071
- •Concept ID:
- C1263857
- •
- Disease or Syndrome
An abnormality characterized by disruption of the normal functioning of peripheral axons.
Motor delay- MedGen UID:
- 381392
- •Concept ID:
- C1854301
- •
- Finding
A type of Developmental delay characterized by a delay in acquiring motor skills.
Progressive neurologic deterioration- MedGen UID:
- 381506
- •Concept ID:
- C1854838
- •
- Finding
Hypointensity of cerebral white matter on MRI- MedGen UID:
- 866563
- •Concept ID:
- C4020908
- •
- Finding
A darker than expected signal on magnetic resonance imaging emanating from the cerebral white matter.
Elevated brain lactate level by MRS- MedGen UID:
- 868368
- •Concept ID:
- C4022762
- •
- Finding
An increase in the level of lactate in the brain identified by magnetic resonance spectroscopy (MRS).
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).
Progressive visual loss- MedGen UID:
- 326867
- •Concept ID:
- C1839364
- •
- Finding
A reduction of previously attained ability to see.
- Abnormality of metabolism/homeostasis
- Abnormality of the eye
- Abnormality of the nervous system
- Ear malformation
