apahsia (dysphasia)
an acquired neurological impairment of processing for receptive and/or expressive language. The result of brain injury, head trauma, CVA, tumor, or infection
fluent aphasia
lesion often in temporoparietal lobe of dominant hemisphere; word output is functional; speech production is function; prosody is acceptable; "empty speech" or jaron; speech lacks any substance; use of paraphasias (substitution of incorrect words)
Wernicke's aphasia
lesion found at the posterior region of the superior temporal gyrus; major fluent aphasia; also known as receptive aphasia; comprehension (reading/auditory) impaired; use of paraphasias; good articulation; use of neologism (fabricated words); impaired writing; poor naming ability
conduction aphasia
lesion of the supramarginal gyrus and arcuate fasciculus; major fluent aphasia; severe impairment with repetition; intact fluency; good comprehension; speech interrupted by word-finding difficulties; reading intact; writing impaired
anomic aphasia
lesion of angular gyrus; minor fluent aphasia; word finding difficulties with writing and speech; functional comprehension; good repetition skills; speech can seem empty; words regarding content are dropped
non-fluent aphasia
lesion often in frontal region of the dominant hemisphere; poor word output; increased effort for producing speech; poor articulation; dysprosodic speech; content of speech is present, but syntactical words are impaired
Broca's aphasia
major non-fluent aphasia; alsown known as "expressive aphasia"; most common form of aphasia; lesions of the 3rd convolution of the frontal lobe; intact auditory and reading comprehension; impaired repetition and naming skills; frequent frustration regarding language skill errors
global aphasia
major non-fluent aphasia; lesion of frontal, temporal, and parietal lobes; comprehension (reading and auditory) is severely impaired; impaired naming and writing skills; impaired repetition skills; may involuntarily verbalized; usually without correct context; may use nonverbal (gestures) skills for communication
verbal apraxia
a non-dysarthric and non-aphasic impairment of prosody and articulation of speech. Verbal expression is impaired secondary to deficits in motor planning. A pt is unable to initiate learned movment even hough they understand the task. lesions are usually found in the left frontal obe adjacent to Broca's area
dysarthria
a motor disorder of speech that is caused by an upper motor neuron lesion that affects the muscles that are used to artculate words and sounds. Speech is often noted as "slurred" and there may also be an effect on respiratory or phonatory systems due to the weakness
