One of the unique characteristics of AHC is that hemiplegic attacks, as well as other symptoms which may co-occur with hemiplegia, cease immediately upon sleep. During strong attacks, the symptoms may reoccur upon waking. [4] [6] Hemiplegic attacks can occur suddenly or gradually, and the severity of an attack can vary over its duration. [6]
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
Guillain-Barr can certainly be life-threatening, although most people make a full or nearly full recovery, according to the Mayo Clinic. The condition becomes dangerous if the paralysis spreads to ...
Paralysis is a very late sign of acute arterial ischemia and signals the death of nerves supplying the extremity. Foot drop may occur as a result of nerve damage. Because nerves are extremely sensitive to hypoxia, limb paralysis or ischemic neuropathy may persist after revascularization and may be permanent. [9]
Cerebral palsy is the most common movement disorder in children, [13] occurring in about 2.1 per 1,000 live births. [2] It has been documented throughout history, with the first known descriptions occurring in the work of Hippocrates in the 5th century BCE. [ 14 ]
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
Continued oxygen deprivation results in fainting, long-term loss of consciousness, coma, seizures, cessation of brain stem reflexes, and brain death. [7] Objective measurements of the severity of cerebral hypoxia depend on the cause. Blood oxygen saturation may be used for hypoxic hypoxia, but is generally meaningless in other forms of hypoxia ...
The most common cause of compartment syndrome in children is traumatic injury. [77] In children <10 years of age, the cause is usually vascular injury or infection. [78] In children >14 years of age, the cause is usually due to trauma or surgical positioning. [78] Treatment for compartment syndrome in children is the same as adults. [72]
