cerebrovascular accidnet (CVA) "Stroke" development of an infarct due to loss in the blood supply to an area of the brain
concussion brain shaken inside of skull from blow or impact; can result in unconsciousness, vomiting, dizziness, unequal pupil size, and shock; 24hrs
epilepsy recurrent disorder of the brain; seizures and loss of consciousness as result of uncontrolled electrical activity of neurons in the brain
hydrocephalus cerebrospinal fluid within the ventricles of the brain; enlarged head
