Ankle clonus- MedGen UID:
- 68672
- •Concept ID:
- C0238651
- •
- Finding
Clonus is an involuntary tendon reflex that causes repeated flexion and extension of the foot. Ankle clonus is tested by rapidly flexing the foot upward.
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.
Fasciculations- MedGen UID:
- 5124
- •Concept ID:
- C0015644
- •
- Sign or Symptom
Fasciculations are observed as small, local, involuntary muscle contractions (twitching) visible under the skin. Fasciculations result from increased irritability of an axon (which in turn is often a manifestation of disease of a motor neuron). This leads to sporadic discharges of all the muscle fibers controlled by the axon in isolation from other motor units.
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.
Torticollis- MedGen UID:
- 11859
- •Concept ID:
- C0040485
- •
- Sign or Symptom
Torticollis is a twisted neck as a result of shortening of sternocleidomastoid muscle. This short and fibrotic muscle pulls the head laterally and rotates the chin and face to the opposite end. Facial asymmetry may be a manifestation (summary by Engin et al., 1997).
Tremor- MedGen UID:
- 21635
- •Concept ID:
- C0040822
- •
- Sign or Symptom
An unintentional, oscillating to-and-fro muscle movement about a joint axis.
Hyperreflexia- MedGen UID:
- 57738
- •Concept ID:
- C0151889
- •
- Finding
Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.
Dysmetria- MedGen UID:
- 68583
- •Concept ID:
- C0234162
- •
- Finding
A type of ataxia characterized by the inability to carry out movements with the correct range and motion across the plane of more than one joint related to incorrect estimation of the distances required for targeted movements.
Mental deterioration- MedGen UID:
- 66713
- •Concept ID:
- C0234985
- •
- Mental or Behavioral Dysfunction
Loss of previously present mental abilities, generally in adults.
Cerebral atrophy- MedGen UID:
- 116012
- •Concept ID:
- C0235946
- •
- Disease or Syndrome
Atrophy (wasting, decrease in size of cells or tissue) affecting the cerebrum.
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.
Gait ataxia- MedGen UID:
- 155642
- •Concept ID:
- C0751837
- •
- Sign or Symptom
A type of ataxia characterized by the impairment of the ability to coordinate the movements required for normal walking. Gait ataxia is characteirzed by a wide-based staggering gait with a tendency to fall.
Head titubation- MedGen UID:
- 299071
- •Concept ID:
- C1608410
- •
- Sign or Symptom
A head tremor of moderate speed (3 to 4 Hz) in the anterior-posterior direction.
Spastic ataxia- MedGen UID:
- 376528
- •Concept ID:
- C1849156
- •
- Disease or Syndrome
Frequent falls- MedGen UID:
- 163408
- •Concept ID:
- C0850703
- •
- Finding
Distal amyotrophy- MedGen UID:
- 338530
- •Concept ID:
- C1848736
- •
- Disease or Syndrome
Muscular atrophy affecting muscles in the distal portions of the extremities.
Reduced visual acuity- MedGen UID:
- 65889
- •Concept ID:
- C0234632
- •
- Finding
Diminished clarity of vision.
Horizontal nystagmus- MedGen UID:
- 124399
- •Concept ID:
- C0271385
- •
- Disease or Syndrome
Nystagmus consisting of horizontal to-and-fro eye movements.
- Abnormality of limbs
- Abnormality of the eye
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
