Abnormal vestibulo-ocular reflex- MedGen UID:
- 867213
- •Concept ID:
- C4021571
- •
- Anatomical Abnormality
An abnormality of the vestibulo-ocular reflex (VOR). The VOR attempts to keep the image stable on the retina. Ideally passive or active head movements in one direction are compensated for by eye movements of equal magnitude.
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.
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.
Areflexia- MedGen UID:
- 115943
- •Concept ID:
- C0234146
- •
- Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Positive Romberg sign- MedGen UID:
- 66017
- •Concept ID:
- C0240914
- •
- Finding
The patient stands with the feet placed together and balance and is asked to close his or her eyes. A loss of balance upon eye closure is a positive Romberg sign and is interpreted as indicating a deficit in proprioception.
Sensory ataxia- MedGen UID:
- 66020
- •Concept ID:
- C0240991
- •
- Sign or Symptom
Incoordination of movement caused by a deficit in the sensory nervous system. Sensory ataxia can be distinguished from cerebellar ataxia by asking the patient to close his or her eyes. Persons with cerebellar ataxia show only a minimal worsening of symptoms, whereas persons with sensory ataxia show a marked worsening of symptoms.
Dysesthesia- MedGen UID:
- 97901
- •Concept ID:
- C0392699
- •
- Disease or Syndrome
Painful sensations elicited by a nonpainful cutaneous stimulus such as a light touch or gentle stroking over affected areas of the body. Sometimes referred to as hyperpathia or hyperalgesia. Often perceived as an intense burning, dyesthesias may outlast the stimulus by several seconds.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk. In general, this can refer to neurological diseases but also fractures or other sources of pain that is triggered upon walking. However, in the current context gait disturbance refers to difficulty walking on the basis of a neurological or muscular disease.
Hyporeflexia- MedGen UID:
- 195967
- •Concept ID:
- C0700078
- •
- Finding
Reduction of neurologic reflexes such as the knee-jerk reaction.
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.
Distal sensory impairment of all modalities- MedGen UID:
- 322937
- •Concept ID:
- C1836527
- •
- Finding
Reduced ability to sense pain, temperature, touch, vibration stimuli in the distal regions of the extremities.
Gait instability, worse in the dark- MedGen UID:
- 324663
- •Concept ID:
- C1837016
- •
- Finding
Impaired distal vibration sensation- MedGen UID:
- 381262
- •Concept ID:
- C1853767
- •
- Finding
A decrease in the ability to perceive vibration in the distal portions of the limbs.
Abnormal cerebellum morphology- MedGen UID:
- 400925
- •Concept ID:
- C1866129
- •
- Anatomical Abnormality
Any structural abnormality of the cerebellum.
Impaired distal proprioception- MedGen UID:
- 867227
- •Concept ID:
- C4021585
- •
- Finding
A loss or impairment of the sensation of the relative position of parts of the body and joint position occuring at distal joints.
Decreased amplitude of sensory action potentials- MedGen UID:
- 870496
- •Concept ID:
- C4024943
- •
- Finding
A reduction in the amplitude of sensory nerve action potential. This feature is measured by nerve conduction studies.
Frequent falls- MedGen UID:
- 163408
- •Concept ID:
- C0850703
- •
- Finding
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
- Ear malformation
