Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
A stroke on the right side of the brain (especially parietal lobe), in addition to producing a homonymous hemianopsia, may also lead to the syndrome of hemispatial neglect. Transient homonymous hemianopsia does not necessarily mean stroke. For instance, it can constitute the aura phase of migraine.
Stroke is the most common source of damage for a right hemisphere damage. The stroke for this disorder occurs in the right hemisphere of the brain. Other etiologies that cause right hemisphere damage include: trauma (traumatic brain injury), disease, seizures disorders, and infections.
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
Hemiparesis, also called unilateral paresis, is the weakness of one entire side of the body (hemi-means "half"). Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body.

[2] [3] Signs and symptoms often appear soon after the stroke has occurred. [3] If symptoms last less than 24 hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. [3] Hemorrhagic stroke may also be associated with a severe headache. [3] The symptoms of stroke can be permanent. [5]
