Transcortical motor aphasia (TMoA), also known as commissural dysphasia or white matter dysphasia, results from damage in the anterior superior frontal lobe of the language-dominant hemisphere. This damage is typically due to cerebrovascular accident (CVA).
Transcortical sensory aphasia is characterized as a fluent aphasia. Fluency is determined by direct qualitative observation of the patient’s speech to determine the length of spoken phrases, and is usually characterized by a normal or rapid rate; normal phrase length, rhythm, melody, and articulatory agility; and normal or paragrammatic speech.

Mixed transcortical aphasia is the least common of the three transcortical aphasias (behind transcortical motor aphasia and transcortical sensory aphasia, respectively). This type of aphasia can also be referred to as "Isolation Aphasia". This type of aphasia is a result of damage that isolates the language areas (Broca's, Wernicke’s, and the ...
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.

In his work, Goldstein studied transcortical sensory aphasia (TSA), characterizing it as impaired auditory comprehension, with intact repetition and fluent speech. [2] Goldstein studied word comprehension in patients with aphasia, theorizing that naming shows relatively little specificity to the site of lesion within the left hemisphere. [3]
A person with anomic aphasia have word-finding difficulties. Anomic aphasia, also known as anomia, is a non-fluent aphasia, which means the person speaks hesitantly because of a difficulty naming words or producing correct syntax. [medical citation needed] The person struggles to find the right words for speaking and writing. [4]
