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.
Fatigable weakness- MedGen UID:
- 451076
- •Concept ID:
- C0947912
- •
- Disease or Syndrome
A type of weakness that occurs after a muscle group is used and lessens if the muscle group has some rest. That is, there is diminution of strength with repetitive muscle actions.
Easy fatigability- MedGen UID:
- 373253
- •Concept ID:
- C1837098
- •
- Finding
Increased susceptibility to fatigue.
Prolonged miniature endplate currents- MedGen UID:
- 350370
- •Concept ID:
- C1864238
- •
- Finding
An abnormal prolongation of the miniature endplate potentials, i.e. the postsynaptic response to transmitter released from an individual vesicle at the neuromuscular junction.
Decreased size of nerve terminals- MedGen UID:
- 871144
- •Concept ID:
- C4025615
- •
- Anatomical Abnormality
A reduction in the size of nerve terminals.
Hyperlordosis- MedGen UID:
- 9805
- •Concept ID:
- C0024003
- •
- Finding
Abnormally increased curvature (anterior concavity) of the lumbar or cervical spine.
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.
Myopathy- MedGen UID:
- 10135
- •Concept ID:
- C0026848
- •
- Disease or Syndrome
A disorder of muscle unrelated to impairment of innervation or neuromuscular junction.
Scoliosis- MedGen UID:
- 11348
- •Concept ID:
- C0036439
- •
- Disease or Syndrome
The presence of an abnormal lateral curvature of the spine.
Neck muscle weakness- MedGen UID:
- 66808
- •Concept ID:
- C0240479
- •
- Finding
Decreased strength of the neck musculature.
Generalized muscle weakness- MedGen UID:
- 155433
- •Concept ID:
- C0746674
- •
- Sign or Symptom
Generalized weakness or decreased strength of the muscles, affecting both distal and proximal musculature.
Decreased muscle mass- MedGen UID:
- 373256
- •Concept ID:
- C1837108
- •
- Finding
Type 1 muscle fiber predominance- MedGen UID:
- 344274
- •Concept ID:
- C1854387
- •
- Finding
An abnormal predominance of type I muscle fibers (in general, this feature can only be observed on muscle biopsy).
Generalized hypotonia- MedGen UID:
- 346841
- •Concept ID:
- C1858120
- •
- Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Type 2 muscle fiber atrophy- MedGen UID:
- 355249
- •Concept ID:
- C1864580
- •
- Pathologic Function
Atrophy (wasting) affecting primary type 2 muscle fibers. This feature in general can only be observed on muscle biopsy.
EMG: decremental response of compound muscle action potential to repetitive nerve stimulation- MedGen UID:
- 892749
- •Concept ID:
- C4021728
- •
- Finding
A compound muscle action potential (CMAP) is a type of electromyography (EMG). CMAP refers to a group of almost simultaneous action potentials from several muscle fibers in the same area evoked by stimulation of the supplying motor nerve and are recorded as one multipeaked summated action potential. This abnormality refers to a greater than normal decrease in the amplitude during the course of the investigation.
Respiratory insufficiency- MedGen UID:
- 11197
- •Concept ID:
- C0035229
- •
- Pathologic Function
Impairment of gas exchange within the lungs secondary to a disease process, neoplasm, or trauma, possibly resulting in hypoxia, hypercarbia, or both, but not requiring intubation or mechanical ventilation. Patients are normally managed with pharmaceutical therapy, supplemental oxygen, or both.
Respiratory insufficiency due to muscle weakness- MedGen UID:
- 812797
- •Concept ID:
- C3806467
- •
- Finding
Anti-acetylcholine receptor antibody positivity- MedGen UID:
- 868186
- •Concept ID:
- C4022578
- •
- Finding
The presence of autoantibodies (immunoglobulins) in the blood circulation that react against ganglioside-monosialic acid (GM1), which is a type of glycosphingolipid with one sialic acid. GM1 is located on the outer layer of the plasma membrane, and plays a vital role in neurogenesis, nerve development, differentiation and repair after injury.
Weak cry- MedGen UID:
- 65892
- •Concept ID:
- C0234860
- •
- Finding
Ptosis- MedGen UID:
- 2287
- •Concept ID:
- C0005745
- •
- Disease or Syndrome
The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective).
Ophthalmoparesis- MedGen UID:
- 155551
- •Concept ID:
