What Causes Wernicke's Aphasia?

Head Trauma

Another common cause of Wernicke’s aphasia is head trauma, where physical damage to the Wernicke’s area leads to this type of aphasia. The most common causes of brain damage include car crashes, falls, and being struck in the head by an object. Often, when there is trauma to the head, the brain moves inside the hard skull, striking the bone, leading to bruising of brain tissue, damage to neurons and the body’s natural response to trauma, swelling. Swelling in the brain can lead to impaired function at the site of the damage. However, if the aphasia is the result of swelling and the pressure can be relieved, the aphasia may be temporary. If the aphasia is the result of direct damage to the tissue, the condition will be permanent.
