What is the mechanism of speech?
Need to repeat/read aloud Auditory and visual cortex Wernicke’s area -(need for Creative speech—>concept area)- Arcuate fasciculus Brock’s area Bilateral corticobulbar and corticospinals Phonation and articulation

Dysarthrias
Dysphonias
What is dysphasia?
Acquired loss of
Production and/or comprehension
Of spoken and/or written language

Cortical area for expressive language (speech, writing, gesture)
In left cortex, inferior frontal gyrus
What is Wernicke’s area?
Cortical area for receptive language
In left cortex
Angular and transverse gyri
What are the types of dysphasia?

How do you assess speech to diagnose speech disorders?
Hearing Articulation Fluency Grammar Paraphasia Comprehension Repetition Reading Writing
What is dysarthria?
Disturbance of articulation
Content and phonation unaffected
What is dysphonia?
Disturbance of sound production
