Individuals who have agraphia with fluent aphasia write a normal quantity of well-formed letters, but lack the ability to write meaningful words. Receptive aphasia is an example of fluent aphasia. [4] Those who have agraphia with nonfluent aphasia can write brief sentences but their writing
Examples include specific language impairment, better defined as developmental language disorder, or DLD, and aphasia, among others. Language disorders can affect both spoken and written language, [1] and can also affect sign language; typically, all forms of language will be impaired.
For example, individuals with linguistic dysprosody may have difficulty distinguishing the production of interrogative and declarative sentences, switching or leaving out the expected rising and falling shift, respectively. [5] Thus, linguistic dysprosody alters an individual's vocal identity and impairs verbal communication. [citation needed]
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in developed countries. [3]
Paraphasia is associated with fluent aphasias, characterized by "fluent spontaneous speech, long grammatically shaped sentences and preserved prosody abilities." [4] Examples of these fluent aphasias include receptive or Wernicke's aphasia, anomic aphasia, conduction aphasia, and transcortical sensory aphasia, among others.
Sentences that are usually problematic will be reworded into active-voiced, declarative phrasings of their non-canonical counterparts. [58] The simpler sentence phrasings are then transformed into variations that are more difficult to interpret. For example, many individuals who have expressive aphasia struggle with Wh- sentences.
The hallmark deficit of this disorder, however, is in repetition. Aphasic people will show an inability to repeat words or sentences when asked by an examiner. [6] [7] After saying a sentence to a person with conduction aphasia, he or she will be able to paraphrase the sentence accurately but will not be able to repeat it. This is possibly ...
Clinical signs include fluent aphasia, anomia, impaired comprehension of word meaning, and associative visual agnosia (inability to match semantically related pictures or objects). As the disease progresses, behavioral and personality changes are often seen similar to those seen in frontotemporal dementia .
