|
|
|
Necrosis
|
Cell death as a result of lack of oxygen/lack of blood flow to region of brain
|
|
|
Infarct

|
|
Hematoma
|
A swelling or mass of blood caused by a break in a blood vessel

|
|
|
Atrophy
|
Wasting away/shrinking in size
|
|
|
Arteriosclerosis
|
Thickening, hardening and loss of elasticity of the walls of the arteries

|
|
Atherosclerosis
|
A type of arteriosclerosis in which there is a focal accumulation of lipids, complex carbohydrates, blood and blood products, fibrous tissue and calcium deposits along the walls of the arteries
|
|
|
Thrombosis
|
Build up of lipids and other items (see atherosclerosis) resulting in stenosis and eventually occulsion of artery
|
|
|
Embolus
|
A thrombosis that breaks away from the arterial wall and travels up the artery and lodges in a more distal artery or vessel
|
|
|
TIA
|
A temporary interruption of blood circulation to a portion of the brain. The symptoms are dependent on the area of the brain affected.
|
|

Loss of voluntary movement/gross limitation in movement

|
|
Hypertension
|
High blood pressure which is a risk factor for stroke and other cerebrovascular diseases.
|
|
|
Aneurysm
|
Localized, balloon like dilation of a blood vessel caused by a weakened arterial wall or congenital defect.

|
Anoxia

Arteriovenous Malformation (AV malformation)
|
Congenital condition in which arteries and veins are tangled and twisted together in a localized area.
|
|
|
Cerebral Vascular Accident (CVA)
|
Sudden onset of focal (not gradual) neurological deficits as a result of ischemia or hemorrhage.
|
|
|
Aphasia
|
A language impairment resulting from a stroke. It affects all modalities of language including speaking, listening, reading and writing although not necessarily to the same degree. It may be accompanied by impairments in cognition and memory.
|
|
|
Stroke/Brain attack
|
Suddenly emerging neurological deficits caused by vascular circulation impairments (e.g. embolism, thrombosis, or hemorrhage)
|
