palsy/pal·sy/ (pawl´ze) paralysis.
palsyNeurology Complete paralysis, see there, of a particular body region or extremity, rendering the region incapable of voluntary motor activity. See Bell's palsy, Cerebral palsy, Crutch palsy, Erb's palsy, Facial palsy, Progressive supranuclear palsy, Pseudobulbar palsy, Saturday night palsy.
palsyAn obsolete term for PARALYSIS, retained for historical reasons in a few cases such as those of BELL'S PALSY and CEREBRAL PALSY.
paralysis; palsy loss of voluntary movement due to muscle injury, neuromuscular pathology, loss of blood supply to subserving motor nerve, or motor nerve dysfunction
abducens nerve palsy See paralysis of the sixth nerve.
Bell's palsy A paralysis of the upper and lower muscles of the face on one side, due to an inflammation of the facial nerve. It results in a wider palpebral aperture and inability to close the eye on the affected size and drying of the cornea. See Bell's sign; artificial tears; crocodile tears.
double elevator palsy A condition characterized by limited or complete inhibition of the upward rotation of an eye, due either to paresis of its superior rectus and inferior oblique muscles, or to entrapment of the inferior orbital tissues. It may be congenital or acquired (e.g. a lesion in the pretectum). Treatment is principally surgical.
gaze palsy Inability of the eyes to make conjugate movements due to a lesion in the cortical or subcortical oculomotor centres. See paralysis of the fourth nerve; paralysis of the sixth nerve; paralysis of the third nerve.
supranuclear gaze palsy A disturbance of the conjugate movements of the eye. If the lesion is in the frontal lobe, the patient is unable to direct the eyes to the contralateral side of the lesion (frontal gaze palsy). In bilateral lesion the patient is unable to turn the eyes voluntarily in any direction but is able to maintain fixation and perform pursuit movements. If the lesion is in the midbrain it produces Parinaud's syndrome, in which there is an inability to elevate (and sometimes depress) the eyes on command and the pupils are large and may not react to light. If the lesion is in the paramedian pontine reticular formation there is ipsilateral horizontal gaze palsy, while lesions in the medial longitudinal fasciculus produce internuclear ophthalmoplegia. See internuclear ophthalmoplegia.
paralysis but preferred by some to refer to certain types of paralysis.
n 2. a nonspecific term representing a group of pathologic conditions having the following common, related characteristics: agenesis, or a lesion of nervous tissue within the cranium; interference with voluntary muscular movements; disabling disorders of a chronic nature, neither acute nor progressive; and occurrence of the original lesion at the date of birth of the patient or before the development of learned muscular function.
3. a condition caused by damage to the motor centers of the brain, resulting in varying disturbances of motor function and often accompanied by mental subnormality.
Patient discussion about palsy
Q. What Is Bell's Palsy? A friend of mine has been told she has Bell's palsy. What happens in this disease?
Here you can learn more about what exactly is Bell's palsy-
Q. What are the causes of bell's palsy?
In my case I have just found out that I have a non milignate tumor behind my left eye which was likely to be the cause of the Bell Pausy in the first place. I encourage anyone who has symptoms or pain spanning more than 8 weeks to see their doctor and if possible request request or demand a MRI scan for peace of mind.
If pain persists get a second opinion and dont let the Dr. shrugg you off.
Q. I go to sleep & use to wake up paralyzed in my sleep. I go to sleep & use to wake up paralyzed in my sleep. But not asleep, just laying there, eyes wide open paralyzed. I couldn't breath, I couldn't speak, move anything but my eyes. I could look around but I couldn't even breathe. This has happened a few times in my old house, once in my mother's house (she lived by the side of a graveyard), and then only once in my new house. What is it and what do you think is causing it?
