Loss of expression power due to brain injury or disease is known as?

1. Trismus

2. Aphasia

3. Anti-emetic

4. Hypoxia

The correct answer is: Aphasia

The term that describes the loss of the ability to express oneself through speech or written language due to brain injury or disease is indeed aphasia. This condition often arises from damage to specific areas of the brain that are responsible for language processing, typically following a stroke, traumatic brain injury, or degenerative disorders. Aphasia can affect various aspects of communication, including the production and comprehension of language, leading to challenges in speaking, understanding spoken language, reading, and writing. Speech therapy is commonly employed as part of the rehabilitation process for individuals experiencing aphasia. The other terms listed relate to different medical conditions: - Trismus refers to a restriction of the opening of the jaws, often resulting from muscle spasms. - Anti-emetic is a type of medication that helps control nausea and vomiting. - Hypoxia refers to a reduced level of oxygen in tissues and can result in various complications in the body, but it does not specifically address language expression. Thus, aphasia is the precise term for the loss of expressive power in the context of brain injuries or diseases.
