Hemiplegia
Definition: paralysis of one side of the body due to pyramidal tract lesion at any point from its origin in the cerebral cortex down to the 5th cervical segment.

B) - Embolic : The source of embolus may be:-
1- Heart2-Distal vessels3-Rare sources: . *Lung
*Bones
C)- Haemorrhagic:1-Intracerebral2-Subarachnoid3-Subdural or extradural

The causes of intracranial haemorrhage are:
•1-Hypertension:
2-Rupture of an intracranial aneurysm angioma
3 -Haemorrhagic blood diseases
4-Trauma to the head:

CLINICAL PICTURE
Onset & Course:•-Acute onset & regressive course (vascular ,
infective & traumatic lesions.)
•-Gradual onset & progressive course (neoplastic lesions).
•-Remittent & relapsing course (D.S.).
![Page 8: Hemiplegia Dr. Shamekh M. El- Shamy. Hemiplegia Definition: paralysis of one side of the body due to pyramidal tract lesion at any point from its origin.](https://reader035.fdocuments.in/reader035/viewer/2022062320/56649cd65503460f9499d66d/html5/thumbnails/8.jpg)
Symptoms & Signs
1-Acute lesions: the clinical picture passes through 2 stages:
•A)-Stage of flaccidity: due to neuronal shock.
•B)-Stage of spasticity: this is the stage of established hemiplegia.
•2-Gradual lesions: the hemiplegia passes directly to the stage of spasticity.
