In aphasia (sometimes called dysphasia), [ a ] a person may be unable to comprehend or unable to 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 the Global North. [ 3 ]
The most common cause of expressive aphasia is stroke. A stroke is caused by hypoperfusion (lack of oxygen) to an area of the brain, which is commonly caused by thrombosis or embolism. Some form of aphasia occurs in 34 to 38% of stroke patients. [23] Expressive aphasia occurs in approximately 12% of new cases of aphasia caused by stroke. [24]

[2] Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate ...
Conduction aphasia is a mild language disability, and most people return to their normal lives. [11] [14] Broca's and Wernicke's aphasia are commonly caused by middle cerebral artery strokes. [15] Symptoms of conduction aphasia, as with other aphasias, can be transient, sometimes lasting only several hours or a few days.
Anomic aphasia (also known as dysnomia, nominal aphasia, and amnesic aphasia) is a mild, fluent type of aphasia where individuals have word retrieval failures and cannot express the words they want to say (particularly nouns and verbs).
