[ 1] Also called double vision, it is a loss of visual focus ...
Diplegia is the most common cause of crippling in children, specifically in children with cerebral palsy. [ 2] Other causes may be due to injury of the spinal cord. There is no set course of progression for people with diplegia. Symptoms may get worse but the neurological part does not change.
A diagnosis for children often requires a shorter symptom duration. For example, the CCC definition only requires three months of persistent symptoms in children compared to six months for adults. [10]: 17–18 NICE requires only four weeks of symptoms to suspect ME/CFS in children, compared to six weeks in adults.
Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy. The main symptom is loss of vision, with colors appearing subtly washed out ...
Education about symptoms and their usual time course is a part of psychological therapy, and is most effective when provided soon after the injury. [51] Since stress exacerbates post-concussion symptoms, and vice versa, an important part of treatment is reassurance that PCS symptoms are normal, and education about how to deal with impairments.

Its symptoms include loss of the brain's ability to control the movement of muscles, tremors, and cardiac arrhythmia. [3] Many cases of LHON plus have been compared to multiple sclerosis because of the lack of muscular control [4] and the presence of demyelinating lesions in the CNS. It is therefore a subtype of MS, according to McDonald's ...
Spaceflight associated neuro-ocular syndrome ( SANS ), [1] previously called spaceflight-induced visual impairment, [2] is hypothesized to be a result of increased intracranial pressure (ICP), although, experiments directly measuring ICP in parabolic flight have shown ICP to be in normal physiological ranges during acute weightless exposure.
