Stroke (cerebral Thrombosis)
Cerebral thrombosis is also recognized as atherosclerotic and thrombotic cerebral infarction and is caused by the pathological changes of cerebral arterial wall together with elevation of blood coagulability, leading to vascular narrowness, obstruction and ischemic changes of the corresponding cerebral tissue, which may be followed by necrosis.
Main points of diagnosis:
1 Stroke is more common in middle-aged and old people. There may be transient numbness of limbs, fatigue and aphasia before the onset of the disease.
2 The attack often occurs in sleep, when the blood pressure is lower and blood flow is slower. A few cases may be seen after strenuous exercise.
3 Neural manifestation include central monoplegia and hemiplegia. They may be accompanied with aphasia, but are often with hemihypoesthesia and hemianopia.
There may also be disphagia and disturbance of consciousness. Unilateral optic atrophy and Horner's syndrome may be present.
