Patients who experienced an ischemic stroke may recover in the days and weeks following the stroke, and then experience a plateau and gradual slowing of recovery. On the contrary, patients who experienced a hemorrhagic stroke experience a slower recovery in the first 4–8 weeks, followed by a faster recovery which eventually stabilizes. [62]
Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...
Symptoms progress over time unlike many other aphasias where symptoms appear immediately after stroke. [17] Wernicke-Korsakoff Syndrome: A well described syndrome of neurological and cognitive problems that comprises both Wernicke's Encephalopathy (WE) and Korsakoff Syndrome (KS). It is often characterized by impairment in memory formation and ...
Broca's, Wernicke's, and the arcuate fasiculus are left intact; however, they are isolated from other brain regions. [2] A stroke is one of the leading causes of disability in the United States. [3] Following a stroke, 40% of stroke patients are left with moderate functional impairment and 15% to 30% have a severe disability as a result of a ...
These fibres are the link between the Wernicke's and Broca's area. Damage to the area connecting comprehension and expression together has the following symptoms: fluent speech, good comprehension, poor oral reading, repetition is poor and transpositions of sounds within words is very common.

When compared to individuals with Broca’s, Wernicke’s, anomic, and conduction types of aphasia, those with Broca’s aphasia showed the best rate and extent of improvement followed by global aphasia. The rate of improvement in language function was highest in the first four weeks after stroke. [30]
Disconnection syndrome can also lead to aphasia, left-sided apraxia, and tactile aphasia, among other symptoms. Other types of disconnection syndrome include conduction aphasia (lesion of the association tract connecting Broca’s area and Wernicke’s), agnosia, apraxia, pure alexia, etc. [4]
Damage to the inferior left temporal lobe, which is shown in green, is associated with TSA. Transcortical sensory aphasia is caused by lesions in the inferior left temporal lobe of the brain located near Wernicke's area, and is usually due to minor hemorrhage or contusion in the temporal lobe, or infarcts of the left posterior cerebral artery (PCA).
