Palsy

Palsy is a medical term which refers to various types of paralysis^[1] or paresis, often accompanied by weakness and the loss of feeling and uncontrolled body movements such as shaking. The word originates from the Anglo-Norman paralisie, parleisie et al., from the accusative form of Latin paralysis, from Ancient Greek παράλυσις (parálusis), from παραλύειν (paralúein, "to disable on one side"), from παρά (pará, "beside") + λύειν (lúein, "loosen"). The word is longstanding in the English language, having appeared in the play Grim the Collier of Croydon, reported to have been written as early as 1599:

Rob. I'll have thee come, I say. Why tremblest thou?
Grim. No sir, not I; 'tis a palsy I have still.^[2]

In some editions, the Bible passage of Luke 5:18 is translated to refer to "a man which was taken with a palsy". More modern editions simply refer to a man who is paralysed. Although the term has historically been associated with paralysis generally, "is now almost always used in connection to the word cerebral—meaning the brain".^[1]

Specific kinds of palsy include:

• Bell's palsy, partial facial paralysis
• Bulbar palsy, impairment of cranial nerves
• Cerebral palsy, a neural disorder caused by intracranial lesions
• Conjugate gaze palsy, a disorder affecting the ability to move the eyes
• Erb's palsy, also known as brachial palsy, involving paralysis of an arm
• Spinal muscular atrophy, also known as wasting palsy
• Progressive supranuclear palsy, a degenerative disease
• Squatter's palsy, a common name for bilateral peroneal nerve palsy that may be triggered by sustained squatting^[3][4][5]
• Third nerve palsy, involving cranial nerve III
