| progressive bulbar paralysis | Progressive weakness and atrophy of the muscles of the tongue, lips, palate, pharynx, and larynx, usually occurring in later life; most often caused by motor neuron disease. Synonym: bulbar palsy, bulbar paralysis, Duchenne's disease, Erb disease, glossolabiolaryngeal paralysis, glossolabiopharyngeal paralysis. (05 Mar 2000) |
|---|---|
| pseudobulbar paralysis | Paralysis of the lips and tongue, simulating progressive bulbar paralysis, but due to supranuclear lesions with bilateral involvement of the upper motor neurons; characterised by speech and swallowing difficulties, emotional instability, and spasmodic, mirthless laughter. (05 Mar 2000) |
| sensory paralysis | Loss of sensation; anaesthesia. (05 Mar 2000) |
| hyperkalaemic periodic paralysis | A form of periodic paralysis in which the serum potassium level is elevated during attacks; onset occurs in infancy, attacks are frequent but relatively mild, and myotonia is often present; autosomal dominant inheritance. (05 Mar 2000) |
| hypokalaemic periodic paralysis | <biochemistry> A rare inherited disorder, affecting men more often than women, characterised by intermittent episodes of muscle weakness or paralysis. One form, known as hypokalaemic periodic paralysis, is an autosomal recessive disorder that is characterised by bouts of muscle weakness (or paralysis) accompanied by low serum potassium levels. Inheritance: autosomal recessive. Incidence: 1 in 100,000. (11 Jan 1998) |
| sleep paralysis | <neurology, physiology> A condition that occurs in REM stage sleep. There is no movement of the skeletal muscles in this stage of sleep. See: REM stage sleep. (27 Sep 1997) |
| hysterical paralysis | A psychosomatic numbness of a limb sometimes to the point of paralysis. See: hysteria. (05 Mar 2000) |
| sodium-responsive periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| spastic spinal paralysis | A type of cerebral palsy in which there is bilateral spasticity, with the lower extremities more severely affected. Compare: flaccid paralysis. Synonym: Erb-Charcot disease, infantile diplegia, Little's disease, spastic spinal paralysis, tabes spasmodica. (05 Mar 2000) |
| spinal paralysis | Loss of motor power due to a lesion of the spinal cord. Synonym: myeloparalysis, myeloplegia, rachioplegia. (05 Mar 2000) |
| normokalaemic periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| supranuclear paralysis | Paralysis due to lesions above the primary motor neurons. (05 Mar 2000) |
| diphtheritic paralysis | <otolaryngology> Paralysis affecting the uvula most frequently, but also any other muscle, due to toxic neuritis; usually appears in the second or third week following the beginning of the attack of diphtheria. Synonym: diphtheritic paralysis. (05 Mar 2000) |
| diver's paralysis | Lay term for decompression sickness. (05 Mar 2000) |
| Duchenne-Erb paralysis | A type of brachial birth palsy in which there is paralysis of the muscles of the upper arm and shoulder girdle (deltoid, biceps, brachialis, and brachioradialis muscles) due to a lesion of the upper trunk of the brachial plexus or of the roots of the fifth and sixth cervical roots. Synonym: Duchenne-Erb paralysis, Erb paralysis. (05 Mar 2000) |
