Aphasia
| Question | Answer |
|---|---|
| Frontal lobe | FRont of brain...reasoning motor skills higher level of cognition.. Brocas area for expressive language. motor cortex recieved info fm lobes and uses to carry out body movements |
| parietal Lobe | middle of brain assocaited with tactile sensory info like pressure touch pain.. somatosensory cortex processes body senses |
| Temporal loBe | located at the bottom primary auditory cortez associated with interpreting sounds and language. Wernickes are needed for lang comprehension |
| Occipital Lobe | located at the back of brain associated with visual stimuli. primary auditory cortex recived interprets info fm the retinas of the eyes. |
| Corpus callosum | connects left and right hemispheres |
| Perisylvian region and Language | important region for language comprehension and production. surrounds the sylvian fissure in LH. includes the brocas, wernickes, angualr gyrus(read and writing) and arcuate fasciculus connects wernickes and brocas imp for repiition |
| Aphasia | language disorder caused by lesion in brain area of production and comphresion. Results from selective involvement of blood vessel or arteries in the brain. |
| Hemiparesis | weakness on one side of the body |
| Hemiplegia | paralysis of one side of body |
| Dysarthria | Difficulty producing speech |
| Dysphagia | Trouble swallowing |
| Causes of aphasia | Stroke,tbi,tumors,seizue,dementia |
| Stroke | CVA leading cause of death wekness numbness on one side of body impaired vision, onset of slurred speech, dizzines dificutly understanding. headches ,nause vomiting. |
| Ischemic Stroke | Obstruction occlusion thromboic/embolic |
| Thrombotic stroke | artery in brain has a blockage accumulation of plaque hardens arteries and causes stenosis or naorrwing of artery |
| Emoblic Stroke | sudden occlusion or narrowing of the artery cause by an embolus a blodd clot borken off a blood vessel. |
| Hemorrahagic strokes | caused by leakage or rupture of blood vessel due to aneurysm or arteriovenous |
| Anuerysm | A baloon like bulge in a weaken artery wall |
| Arteriovenous | Collections of weak thin wall veins and arteries on the surface of the brain or within the brain. |
| recoery of ischemic vs hemmorahgic | ischemic best recovery in first week and then it slows. hemorrhagic more severe very little recovery 4-8 weeks then rapid recovery then it stablizies and then it goes up like stair cases. |
| Medical conditions associated with stroke | diabetes, hypertension, obesity, high cholesterol,smoking,drug abuse, |
| Anomia | naming difficulty |
| Aggramatism | ommision of grammatical elements like prepositions (she shovel snow-she was shoveling the snow) |
| paraphrasia | word subsitution..phonemic paraphrasia |
| phonemic paraphrasia | phoneme substitution |
| Semantic paraphrasia | in same category |
| jargon | meaningless irrelevant speech |
| neologism | novel word |
| Types of aphasia | fluent)anomic, wernickes, conduction vs non fluent (brocas, global) |
| Brocas aphasia | damge to front of lobe where its important for language production and primary motor cortex.... non fluent speech..short sentences with aggramatism, anomia, poor repetition,slow speech and writing, phonemic paraphrasia, good comprehension |
| Wernickes Aphasia | temporal lobe damage important for language comprehension. Fluent speech.. poor comprenhension good production logorrhea, semantic paraphrasia anomia poor repetition, neologism, jargons. |
| Anomic Aphasia | anomia severe, fluent speech mild to moderate speech comprehension. |
| Conduction Aphasia | damage to arcuate, bad repeption, fluent speech anomia mild comprehension defecits |
| Global aphasia | non fluent poor comprehension poor repetions, anomia, profound language impairments in all modalities. |
| Diagnosis of Aphasia | anomia, speech fluency, paraphrasia, neologism, repetition, language comprehension |
