Absent Achilles reflex- MedGen UID:
- 108240
- •Concept ID:
- C0558845
- •
- Finding
Absence of the Achilles reflex (also known as the ankle jerk reflex), which can normally be elicited by tapping the tendon is tapped while the foot is dorsiflexed.
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).
Chorea- MedGen UID:
- 3420
- •Concept ID:
- C0008489
- •
- Disease or Syndrome
Chorea (Greek for 'dance') refers to widespread arrhythmic involuntary movements of a forcible, jerky and restless fashion. It is a random-appearing sequence of one or more discrete involuntary movements or movement fragments. Movements appear random because of variability in timing, duration or location. Each movement may have a distinct start and end. However, movements may be strung together and thus may appear to flow randomly from one muscle group to another. Chorea can involve the trunk, neck, face, tongue, and extremities.
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.
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.
Choreoathetosis- MedGen UID:
- 39313
- •Concept ID:
- C0085583
- •
- Disease or Syndrome
Involuntary movements characterized by both athetosis (inability to sustain muscles in a fixed position) and chorea (widespread jerky arrhythmic movements).
Unsteady gait- MedGen UID:
- 68544
- •Concept ID:
- C0231686
- •
- Finding
A shaky or wobbly manner of walking.
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.
Dysdiadochokinesis- MedGen UID:
- 115975
- •Concept ID:
- C0234979
- •
- Sign or Symptom
A type of ataxia characterized by the impairment of the ability to perform rapidly alternating movements, such as pronating and supinating his or her hand on the dorsum of the other hand as rapidly as possible.
Delayed speech and language development- MedGen UID:
- 105318
- •Concept ID:
- C0454644
- •
- Finding
A degree of language development that is significantly below the norm for a child of a specified age.
Hyporeflexia- MedGen UID:
- 195967
- •Concept ID:
- C0700078
- •
- Finding
Reduction of neurologic reflexes such as the knee-jerk reaction.
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.
Lower limb spasticity- MedGen UID:
- 220865
- •Concept ID:
- C1271100
- •
- Finding
Spasticity (velocity-dependent increase in tonic stretch reflexes with increased muscle tone and hyperexcitable tendon reflexes) in the muscles of the lower limbs, hips, and pelvis.
Reduced tendon reflexes- MedGen UID:
- 356648
- •Concept ID:
- C1866934
- •
- Finding
Diminution of tendon reflexes, which is an invariable sign of peripheral nerve disease.
Oculomotor apraxia- MedGen UID:
- 483686
- •Concept ID:
- C3489733
- •
- Disease or Syndrome
Ocular motor apraxia is a deficiency in voluntary, horizontal, lateral, fast eye movements (saccades) with retention of slow pursuit movements. The inability to follow objects visually is often compensated by head movements. There may be decreased smooth pursuit, and cancelation of the vestibulo-ocular reflex.
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.
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.
Telangiectasia- MedGen UID:
- 21088
- •Concept ID:
- C0039446
- •
- Finding
Telangiectasias refer to small dilated blood vessels located near the surface of the skin or mucous membranes, measuring between 0.5 and 1 millimeter in diameter. Telangiectasia are located especially on the tongue, lips, palate, fingers, face, conjunctiva, trunk, nail beds, and fingertips.
Hypometric saccades- MedGen UID:
- 98065
- •Concept ID:
- C0423082
- •
- Finding
Saccadic undershoot, i.e., a saccadic eye movement that has less than the magnitude that would be required to gain fixation of the object.
Impaired smooth pursuit- MedGen UID:
- 325176
- •Concept ID:
- C1837458
- •
- Finding
An impairment of the ability to track objects with the ocular smooth pursuit system, a class of rather slow eye movements that minimizes retinal target motion.

- 870464
- •Concept ID:
- C4024910
