Aphasia: the causes

Aphasia results from an alteration in a cerebral area of ​​the language. The determination of its location depends on its symptomatology.

Thus, an alteration in the area of ​​Broca causes a lack of the word and a difficulty of articulation. Indeed, this area, located in the frontal lobe (part of the brain that is in front), is responsible for the production of speech.

An attack on the Wernicke area causes a loss of understanding and denomination. The person only utters a simple incomprehensible jargon. This area located in the temporal lobe (part of the brain that is on the side) is responsible for understanding the language.

As for the supramarginal convolution, this is the area not far from the Wernicke area and responsible for the repetition of the words heard.

It also happens that a deeper attack of the brain, in the central gray nuclei or the white substance, causes an aphasia. Indeed, language is a complex phenomenon for which many brain functions come into play.

The type of cerebral involvement involved in aphasia is variable: the alteration may be secondary to an accident or physical aggression that caused head trauma, or following a neurosurgical operation with removal of part of the brain

Other diseases, such as stroke, brain tumor, brain infection (encephalitis), may be involved in the development of aphasia. Finally, dementia, the most common being Alzheimer's disease, may explain aphasia.
