Causes of Brain Damage
Brain tumors Cerebrovascular disorders Closed-head injuries Infections of the brain Neurotoxins Genetic factors
Brain Tumors
A tumor (neoplasm) is a mass of cells that grows independently of the rest of the body – a cancer
~20% of brain tumors are meningiomas – encased in meninges Encapsulated, growing within their own membranes Usually benign, surgically removable
Brain Tumors
Most brain tumors are infiltrating Grow diffusely through surrounding tissue Malignant, difficult to remove or destroy
About 10% of brain tumors are metastatic – they originate elsewhere, usually the lungs
Cerebrovascular Disorders
Stroke – a sudden-onset cerebrovascular event that causes brain damage Cerebral hemorrhage – bleeding in the brain Cerebral ischemia – disruption of blood supply
3rd leading cause of death in the US and most common cause of adult disability
