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).
Impulsivity- MedGen UID:
- 43850
- •Concept ID:
- C0021125
- •
- Mental or Behavioral Dysfunction
Acting on the spur of the moment in response to immediate stimuli; acting on a momentary basis without a plan or consideration of outcomes; having difficulty establishing or following plans; experiencing a sense of urgency and engaging in self-harming behavior when under emotional distress.
Myoclonus- MedGen UID:
- 10234
- •Concept ID:
- C0027066
- •
- Finding
Very brief, involuntary random muscular contractions occurring at rest, in response to sensory stimuli, or accompanying voluntary movements.
Oppositional defiant disorder- MedGen UID:
- 18178
- •Concept ID:
- C0029121
- •
- Mental or Behavioral Dysfunction
An enduring pattern of uncooperative, defiant, and hostile behavior towards authority figures that does not involve major antisocial violations, is not accounted for by the child's developmental stage, and results in significant functional impairment. A certain level of oppositional behavior is common in children and adolescents.
Tremor- MedGen UID:
- 21635
- •Concept ID:
- C0040822
- •
- Sign or Symptom
An unintentional, oscillating to-and-fro muscle movement about a joint axis.
Encephalopathy- MedGen UID:
- 39314
- •Concept ID:
- C0085584
- •
- Disease or Syndrome
Encephalopathy is a term that means brain disease, damage, or malfunction. In general, encephalopathy is manifested by an altered mental state.
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.
Short attention span- MedGen UID:
- 82652
- •Concept ID:
- C0262630
- •
- Finding
Reduced attention span characterized by distractibility and impulsivity.
Global developmental delay- MedGen UID:
- 107838
- •Concept ID:
- C0557874
- •
- Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
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.
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
Brisk reflexes- MedGen UID:
- 382164
- •Concept ID:
- C2673700
- •
- Finding
Tendon reflexes that are noticeably more active than usual (conventionally denoted 3+ on clinical examination). Brisk reflexes may or may not indicate a neurological lesion. They are distinguished from hyperreflexia by the fact that hyerreflexia is characterized by hyperactive repeating (clonic) reflexes, which are considered to be always abnormal.
Impaired tandem gait- MedGen UID:
- 476998
- •Concept ID:
- C3275367
- •
- Finding
Reduced ability to walk in a straight line while placing the feet heel to toe.
Bilateral tonic-clonic seizure with generalized onset- MedGen UID:
- 1368929
- •Concept ID:
- C4476643
- •
- Sign or Symptom
A bilateral tonic-clonic seizure with generalized onset is a type of bilateral tonic-clonic seizure characterized by generalized onset; these seizures rapidly engage networks in both hemispheres at the start of the seizure.
Type 2 muscle fiber predominance- MedGen UID:
- 478817
- •Concept ID:
- C3277187
- •
- Finding
An abnormal predominance of type II muscle fibers (in general, this feature can only be observed on muscle biopsy).
Horizontal nystagmus- MedGen UID:
- 124399
- •Concept ID:
- C0271385
- •
- Disease or Syndrome
Nystagmus consisting of horizontal to-and-fro eye movements.
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.
Slow saccadic eye movements- MedGen UID:
- 232942
- •Concept ID:
- C1321329
- •
- Finding
An abnormally slow velocity of the saccadic eye movements.
- Abnormality of the eye
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
