Aphasia is a language disorder caused by brain injury, often as a result of a stroke (CVA). People with aphasia have difficulty speaking, understanding, reading or writing because language areas in the brain are damaged. Thinking, however, remains intact, but the ability to use or understand language is impaired.

What are the causes of aphasia?

Aphasia is usually caused by a stroke or another type of brain injury, such as a brain hemorrhage, cerebral infarction, trauma or tumor. The brain injury often affects the language areas in the left hemisphere of the brain, affecting speech and language skills.

What forms of aphasia are there?

There are different forms of aphasia, depending on the type and severity of the brain injury:

• Expressive aphasia (Broca aphasia): Difficulty pronouncing words or forming sentences, but comprehension of language is largely intact.
• Receptive aphasia (Wernicke aphasia): Difficulty understanding spoken or written language, while speaking is often fluent, but sometimes incoherent or meaningless.
• Global aphasia: Severe damage to both understanding and production of language, often due to extensive brain damage.

What are the consequences of aphasia?

Aphasia has a major impact on daily life. People with aphasia may have difficulty communicating, which can cause frustration and affect social relationships. Aphasia can also lead to problems at work or in studies, as communication is essential in many tasks. In addition, it can lead to social isolation and psychological symptoms such as anxiety or depression.

How is aphasia treated?

The treatment of aphasia focuses on restoring language skills through speech therapy. Speech therapists help people with aphasia by providing exercises aimed at improving speech, language comprehension, reading and writing. Treatment is tailored to the patient’s specific needs and abilities. In many cases, long-term therapy is needed to make progress. Early intervention after a stroke or brain injury is important to increase the likelihood of recovery.
