Glutamate is an excitatory neurotransmitter that, in excessive amounts, causes excitotoxicity by promoting calcium influx into neurons. [8] This influx can lead to neuronal death, [8] contributing to brain damage of the emotional regulation and reward pathways in the prefrontal cortex, amygdala, and especially the hippocampus.
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]
