Causes of Brain Damage

- Brain Tumors

- Cerebrovascular disorders

- cell death

- Closed-head injuries

- Infections of the brain

- Neurotoxins

- Genetic factors

Brain Tumors

- A tumour (neoplasm) = independently growing cell mass without any physiological function (cancer)

- Types of tumors

- Meningiomas: 20% of tumours; growing between meninges; encapsulated (within own membrane), usually benign

- Infiltrating tumours: Most tumours are inflitrating. Grow diffusely through surrounding tissue, typically malignant, difficult to remove or destroy

- Metastatic tumours: 10% of brain tumours; originate elsewhere, usually lunga, skin, breats

- Metastasis - transmission of disease from one organ to another
