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]
Landau–Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, [1] or aphasia with convulsive disorder, is a rare neurological syndrome that develops during childhood. [2] It is named after William Landau and Frank Kleffner, who characterized it in 1957 with a diagnosis of six children. [3] [4]
[19] [12] Aphasia is a disorder that is acquired, therefore it occurs in individuals that have already developed language.

[20] All areas of language are affected by aphasia including expressive and receptive language abilities. [20]

Conduction aphasia is a mild language disability, and most people return to their normal lives. [10] [13] Broca's and Wernicke's aphasia are commonly caused by middle cerebral artery strokes. [14] Symptoms of conduction aphasia, as with other aphasias, can be transient, sometimes lasting only several hours or a few days.

Damage to the surrounding areas (perisylvian region) may also result in Wernicke's aphasia symptoms due to variation in individual neuroanatomical structure and any co-occurring damage in adjacent areas of the brain. [2] Another common cause of Wernicke's aphasia is encephalitis, specifically around the posterior superior temporal gyrus.
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]
