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).

- 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.
Abducens nerve palsy- MedGen UID:
- 1645218
- •Concept ID:
- C4551519
- •
- Disease or Syndrome
Malfunction of the abducens nerve as manifested by impairment of the ability of the affected eye to be moved outward. Patients who develop abducens nerve palsy often present with binocular horizontal diplopia, which is a double vision when looking at objects side by side. There will be a notable weakness of the ipsilateral lateral rectus muscle leading to a deficit in of eye abduction on the affected side. Some patients may present with a constant head turning movement to maintain binocular fusion and to lessen the degree of diplopia.
Brain atrophy- MedGen UID:
- 1643639
- •Concept ID:
- C4551584
- •
- Disease or Syndrome
Partial or complete wasting (loss) of brain tissue that was once present.
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.
Bradypnea- MedGen UID:
- 66670
- •Concept ID:
- C0231837
- •
- Finding
Bradypnea is referring to breathing that is abnormally slow.
Respiratory failure- MedGen UID:
- 257837
- •Concept ID:
- C1145670
- •
- Disease or Syndrome
A severe form of respiratory insufficiency characterized by inadequate gas exchange such that the levels of oxygen or carbon dioxide cannot be maintained within normal limits.
Lactic acidosis- MedGen UID:
- 1717
- •Concept ID:
- C0001125
- •
- Disease or Syndrome
An abnormal buildup of lactic acid in the body, leading to acidification of the blood and other bodily fluids.
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).
Skin erosion- MedGen UID:
- 854383
- •Concept ID:
- C3887524
- •
- Disease or Syndrome
A discontinuity of the skin exhibiting incomplete loss of the epidermis, a lesion that is moist, circumscribed, and usually depressed.
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.
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.
Vertical supranuclear gaze palsy- MedGen UID:
- 334385
- •Concept ID:
- C1843369
- •
- Disease or Syndrome
A supranuclear gaze palsy is an inability to look in a vertical direction as a result of cerebral impairment. There is a loss of the voluntary aspect of eye movements, but, as the brainstem is still intact, all the reflex conjugate eye movements are normal.
