Traumatic Brain Injuries And Anoxic Brain Injuries Flashcards
What can acquired brain injuries be
Traumatic
or non traumatic- which are a result of stroke, infections, tumours surgical complications, endocrine disorders drug reactions, anoxia
What’s a traumatic brain injury
Injury to the brain caused by trauma to the head many possible causes
Causes of TBI
Automobile accidents, slipping, falling, being shaken violently, sports related acts
Types of TBI
Closed head injuries, diffuse axonial injury, coup contraction concussion, temporary disruption of brain function, intracranial haematoma- ruptured blood vessel results in pool of blood around brain or between brain and skull, cerebral contusion- bleeding on the brain
What are open wound injuries
Often life threatening occur when a blow occurs that is forceful enough to penetrate the skull
What are crushing injuries
Occur when the brain is compressed between 2 objects, although rare most damaging and life threatening
Signs and symptoms
Difficulty concentrating or confusion changes in consciousness, dizziness, headaches, vomiting, mood changes and behaviour, swelling and site of the injury difficulty with speech, changes in vision, hallucination
What’s a vegetative state
Severe, sleep cycles, no conscious awareness of themselves or surroundings
Minimally conscious state
Show limited signs of awareness. And response to stimulation, difficult to remain responsive or awake for any length of time
What’s locked in syndrome
Condition where someone is aware of themselves or surroundings but unable to move or speak
What’s anoxic brain injury
Occurs when the brain is deprived of oxygen, left without oxygen for too long, neural cells begin to die through apoptosis when a large number of brain cells die patients can be left with diminished brain function
Causes of anoxic brain injury
Stroke, TIA, anaphylactic shock, pneumothorax, electrocution, low blood pressure, oxygen deprivation at birth, physical attack, drug overdose
Types of anoxic brain injuries
Diffuse cerebral hypoxia, focal cerebral ischaemia, global cerebral ischaemia, cerebral infarction
Immediate Signs and symptoms of ABI
Confusion, loss of consciousness, feeling woozy or dizzy , intense headache, vomiting, changes in behaviour or sensation
Signs and symptoms of all acquired BIA
Dependent on area of the brain affected, frontal lobe, temporal lobe, occipital lobe, parietal lobe, brain stem, cerebellum
