Assessing Aphasia and Neurogenic CDs
These theories focus on function of areas surrounding the injury; in the case of language impairment
Fluent (aphasic patients) have normal or near normal speech rates and use a variety of different grammatical constructions; function words and grammatical inflections are present, and usually syntactically appropriate. Intonation patterns are present and usually appropriate. Nonfluent (aphasic patients) have slow and labored speech. The variety of grammatical constructions is often restricted and intonation may be reduced or absent; function words and grammatical affixes may be omitted, and patients may rely a lot on nouns (Howard & Hatfield, 1987, p. 147).
Damage posterior to the Rolandic Fissure
Sph flows smoothly and effortlessly
Fluent aphasic spkrs. Usually manipulate rate, intonation, and stress
Damage anterior to the Rolandic Fissure
Sph is halting and made with great effort
Rate is slower than normal, intonation is limited, stress is missing (diminished)
