Document Summary
Types o stroke o anoxia o aneurysm o tumour. Traumatic brain injury o not: congenital disorders, progressive disorders or psychiatric disorders stroke. Ischaemic (thrombosis or embolism) o clot stops blood supply to an area of the brain o atheroma (line artery endothelium: haemorrhagic: rupturing of an aneurysm o blood leaks out into the brain tissue o pressure. = tissue death o can occur in any blood vessel which supplies the brain (including eye) o. Intracerebral haemorrhage (inside the brain) o subarachnoid haemorrhage (inside the sub arachnoid space) Increased intracranial pressure o hypoxia o brain swelling o post-traumatic epileptic seizures: consequences o physical. Irritability: fatigue, headache, paralysis, chronic pain o emotional, amotivation, socially inappropriate behaviour, depression o cognitive, memory problems, slowed responses, poor planning and problem solving. Encoding: transform sensory stimuli into neural signals: retrieval: locating the item and using it (recall vs recognition) Stimuli sensory register stm ltm o can be lost at all stages but stimuli (obvs)
