Hemiplegia is a condition in which one-half of a patient's body is paralyzed. Hemiplegia is more severe than hemiparesis, wherein one half of the body is weakened but not paralysed.[1]

[edit] Causes
Hemiplegia can be congenital or acquired, as from illness or stroke.
It is usually the result of a stroke, although disease processes affecting the spinal cord and other diseases affecting the hemispheres are equally capable of producing this clinical state. Hemiplegia can be a more serious consequence of stroke than spasticity.[2]
Cerebral palsy can also affect one hemisphere, resulting in limited function. This does not cause paralysis but instead causes spasms. Cerebral palsy where this is the only symptom is often referred just as hemiplegia.
Other causes include Type 2 diabetes mellitus, which can lead to transient hemiplegia, a type of spinal injury called Brown-Sequard syndrome, medial medullary syndrome, and injections of local anaesthetic accidentally given intra-arterially instead of into a nerve branch. Lesions of the posterior limb of the internal capsule can also lead to hemiplegia.
it's a pyramidal tract lesion from the origin at the cerebral cortex down to 5th cervical segment of the spinal cord.
1-vascular:- stroke ((the most common cause))
2-infective:- encephalitis -meningitis - brain abscess
3-neoplastic:- glioma-meningioma
4-demylination:- DS disseminated sclerosis
5-traumatic:- cerebral lacerations
6-congenital:-cerebral palsy
7-hysterical:-absence of organic pyramidal lesion
[edit] Hemiplegic migraine
Hemiplegic migraine is a form of migraine during which the person will experience the feeling of numbness on one side of their body. This feeling will usually pass within 2-12 hours. Oliver Sacks writes on this subject in his book 'Migraine'.
