Trauma and more disorders.. Psychology 2617
Introduction • Lesions • Anoxia a hypoxia • Anoxia is a complete cutoff of oxygen while hypoxia is a decrease • Hypoxia is usually caused by some environmental factor
Cerebrovascular disorders • Stroke • Aka CVA • Used to be treated basically like there was nothing you could do • Now more like a ‘brain attack’
Ischemia • Usually short lived • Usually a near complete or complete recovery occurs • More likely later on to have a big time stroke • Usually involves impairment of speech, vision, maybe neglect
Infarctions • Thrombosis • Basically a blockage • Embolism • Clot that moves to the brain • Both are related to fat type build ups in the arteries
hemorrhage • Rupture and spilling of blood in the brain • Usually a weak spot (aneurysm) • Intracerebral • Subarachnoid
diagnosis • Depends on the problem • Tough sometimes for TIAs • Easier with other problems, hemorrhage is easy, but the outlook is not that good anyway • Use of imaging
Psychological problems post event • Sensory problems • Cognitive issues • Memory • Motor • Speech • Abstract reasoning • Not always associated with where the injury happened!
Tumors • Malignant or benign • Infiltrative or encapsulated • MUCH easier to diagnose nowadays what with MRI and CT scanning • Radiation and chemo • Chemo best when the tumor is growing • Early detection is key then
Head injury • Is it just me or is all of this stuff getting depressing…. • We didn’t evolve in an environment that allowed us to travel at hundreds of km/h • Penetrating injury • Closed head injury
Glasgow Coma Scale • Eye opening • Verbal response • Motor response • From 3-15, 15 is ok, 3 is very bad • The funny funny story of Donnie…
Types of injuries • Edema • Herniation • Hemorrhage • Bleeding • Skull fractures
Concussion • A mild form of closed head injury • Well mild sure, but, you should get looked at • They are cumulative • The funny story of Donnie maybe ain’t that funny • Brett is the smart Lindros • Post concussion syndrome
Treatment • Amnesia is often the result or one of them • Neuropsychological evaluations • Coping skills can be taught • As usual, less severe, easier to treat
