acuired neurological impairment of processing for receptive &/or expressive language; fluent vs non-fluent; good vs poor comprehension; good vs poor repetition
Dysarthria
Upper motor neuron lesion that affects mm's used to articulate words/sounds; motor disorder of speech; slurred speech; may be an effect on respiratory or phonatory systems due to the weakness
Wernicke's Aphasia
LESION: post. region of superior temporal gyrus; major fluent aphasia; AKA receptive aphasia; comprehension (r/a) impaired; use of paraphasias; use of neologisms; impaired writing; poor naming ability; good articulation; often unaware of mistakes/environ.
Fluent Aphasia
LESION:often temporal lobe of DOM Hem; word output fxn'l; speech production fxn'l; prosody acceptable; "empty speech" or jargon; speech lacks any substance; use of paraphasias
Broca's Aphasia
LESION:3rd convolution of frontal lobe; major NFA; AKA expressive aphasia;most common; intact a/r comprehension;impaired repetition/naming skills;frustration w/lang. skills/errors;speaks short meaningful phrases produced c/great effort; assoc. w/R hemipar
Poor prognosis
perseveration of speech; severe auditory comprehension impairments; unreliable yes/no answers; use of "empty speech" w/o recognition of impairment
Conduction Aphasia
LESION:supramarginal gyrus & arcuate fasciculus; major fluent aphasia; severe impairment c/repetition; speech interrupted by word finding difficulties; impaired writing; good comprehension; reading intact; intact fluency;
Anomic Aphasia
LESION:angular gyrus; minor fluent aphasia; word finding dificulties c/writing speech; speech seems empty - words regarding content are dropped; fxn'l comprehension; good repetion skills
Non-fluent aphasia
LESION:often frontal region of DOM Hem; poor word output; increased effort for producing speech; poor articulation; dysprosodic speech; content of speech is present but syntactical words are impaired
Verbal Apraxia
LESION:usually L frontal lobe adj. to Broca's Area; Non-dysarthric; non-aphasic; verbal impairment of prosody/articulation of speech due to deficits in motor planning
