• casued by a blow to the head
• Brain injury that may result in a headache altered levels of lertness, loss of consciousness, or memory loss of events surrounding injury
• most people who sytain a concussion never lose consciousness or even realize thaey had concusssion

• memory
• judgement
• reflexes
• speech
• balance and coordination

a form of traumatic brain injury that may lead to leakage of small blood vessels in the brain(blood clots may form and the brain swells interupting motor functions of the brain)

surgery to reduce intracranial pressure and remove blood clot

• Break in a bone surrounding the brain
• may occur with or without brain damage

• Brain stem (vital cener) disruption may occur iwth fracture at base of the skull
• increased cerbrospinal fulid
• bleeding
• incrfeased intracranial pressure
• bacerial infection

• Considered a type of stroke
• caused by artery in the brain bursting and produsing localized bleeding in the surrounding tissues
• accoutns for about 13% of strokes
• often casue by a skull fracture

• blood from trauma irritaes brain tissues cand cause swelling aka cerebral edema
• pooled blood collects into a mass called a hematoma
• these conditions increase pressure on nearby brain tissue, and reduce vital blookd flow and kills brain cells

• extradural or epidural hemorrhage -bleeding into the space between the dura mater and the skull
• subdural hemorrhage - collection of blood on the surface of the brain

• may grow and compress vital nerve centers
• encapsulated
• removed surgically
• example - astrocytoma, behign slow-growing tumor

• May have exensive projections and invade other tissues making complete removal difficult or impossible
• usuallyl metastasize form other organs such as lung and breast

• gliomas-tumors of glial (cell that supports the verve tissue) cells
• i.e. giobastomas are highly maligant, rapidly-growing tumors

• headaches due to increased intracranial pressure
• behavioral or personality changes
• memory loss
• visual disturbancess
• imparied speech
• muscle weakness
• impaired corrdination
• seizures
• coma

brain imaging

• osmotic diuretics
• glucocorticosteroids
• surgery

• trigeminal neuraligia, aka tic doulorex
• inflamation of the fith cranial or trigeminal verve
• casuses severe intermittent pain
• idiopathic
• know triggers include stress MS, tumor compressing the nerve

• pain med
• anitconvulsant med
• centrally-actiing muscle relaxants
• alcohol or phenol injection into nerve as it exits skull for cases
• rhizotomy

• inflamation of the seventh cranial or facial nerve that innervates facial muscle and salavary gladns
• causes saddign of facial muscle on one side of the face and watery eye
• causes frooling and slurred speech
• idopathic
• known triggers include viruses, autoimmune disorders or vascular ischemia
• recovery takes weeks
