Bruce Willis' family shared on Instagram that the actor is stepping away from his career due to health concerns, including a recent aphasia diagnosis. Aphasia is a condition that can impact one’s ability to communicate.
What exactly is aphasia?
Aphasia comes in various forms, but all of them share the common issue of impairing one’s ability to speak or comprehend speech. (The term comes from Greek, meaning “without speech.”)
Aphasia is a condition that specifically affects the areas of the brain responsible for language, even though a person may still have normal cognition and no issues with their hearing or speech organs. People with aphasia may find it difficult to express themselves or understand spoken language, despite being mentally sharp otherwise.
For instance, Wernicke’s area in the brain is crucial for processing language. When this area is damaged, it can lead to Wernicke’s aphasia, where individuals can speak but struggle to comprehend what others say, or even understand themselves. A hallmark symptom is speaking in long, nonsensical sentences.
Another critical region, Broca’s area, governs language production. Damage to this part of the brain causes Broca’s aphasia, where individuals may manage a few words but struggle to form coherent sentences.
Other forms of aphasia include conduction aphasia, which impairs the ability to repeat what one hears, and anomic aphasia, where people forget the names of objects. Global aphasia can affect multiple aspects of language use. Related conditions such as alexia (difficulty reading) and agraphia (difficulty writing) can also occur, and some individuals may experience more than one of these at once.
What causes aphasia in individuals?
Anything that causes localized damage to the brain can potentially lead to aphasia. Stroke is one of the primary causes of aphasia, and it can itself be triggered by cardiovascular diseases or other conditions that affect the circulatory system. For most individuals, the brain's language processing regions are located on the left side, meaning that a stroke affecting the left side of the brain can cause aphasia, in addition to weakness or paralysis on the right side of the body.
Other factors that can contribute to aphasia include brain injuries, infections, and tumors that impact the brain.
Is it possible to recover from aphasia?
As individuals recover from the cause of their aphasia, they may often regain some of their brain functions. Speech-language therapy can assist by helping them relearn lost abilities and also by enabling them to utilize the skills they retained. For instance, someone struggling with speech may rely more on gestures or written communication.
If someone in your life is affected by aphasia, the National Institute of Deafness and Communication Disorders provides further information on aphasia here, and the Aphasia Institute offers resources for patients and families here.
