Aphasia is classified by
1. Pattern of language deficits
2. Site of lesion
Name the 4 lobes of the brain
Frontal, parietal, temporal, occipital
Altered level of consciousness, sudden weakness, numbness, drooling, paralysis, difficulty speaking, headache
Stroke signs and symptoms
Wernikes, anomic, conduction, transcortical sensory is what kind of aphasia
Fluent Aphasia
Caused by blockage of an artery (thrombosis, embolism)
Ischemic stroke
Type of aphasia causing the person to be unable to understand or produce meaningful language
Wernikes aphasia
Regulates responsiveness of primary motor cortex, controls speech, hands, finger and hand-eye coordination, Brocas area
Premotor cortex
Diet and exercise, reducing hypertension, reducing stress, etc.
Stroke prevention
Word retrieval/word finding problems
Anomia
Blood clot within the brain
Thrombosis
When a person is unable to speak fluently, mispronounce words, and speak haltingly
Broca's aphasia
Language association; wernikes area, analysis and elaboration of speech sounds, comprehension of spoken language, verbal memory, language in dominate hemisphere, etc.
Temporal lobe
3 structural levels of blood supply
arteries in neck, interconnecting arteries in base of the brain (circle of willis), cerebral arteries on surface of the cortex
Speech production and comprehension are intact but person is unable to repeat something that has been said
conduction aphasia
Clot that forms in other parts of the body
embolism
Non fluent aphasia with impairment to both Broca's and Wernikes' area
Global Aphasia
Regulates motor function and muscle tone
Basal ganglia
Ischemic core
Comprehension is poor but ability to repeat is retained
Transcortical sensory aphasia
Bleeding in the brain
hemmoragic stroke
mixed non fluent aphasia
Relays messages between lower brain centers and cerebral cortex. Contributes to cortically mediated speech and language functions
Thalamus
Smoking, high cholesterol, high blood pressure, diabetes, heart disease
Risk factors of stroke
Brocas, transcortical motor, and global are what kinds of aphasia
Non fluent aphasia
Other etiologies of a stroke
TBI, Brain tumor, infection, neurogenic disease
