What Are the Types of Dysphasia?
Dysphasia can be divided into different types and subtypes. Each type is associated with damage to a particular region of the brain. However, people with dysphasia have less common distinctions. Brain damage is clear-cut.
Broca’s dysphasia
Broca’s dysphasia, also known as Broca’s aphasia, is one of the most popular types of dysphasia. It occurs when a region of the brain, known as the Broca’s area, is damaged. Broca’s area [6] is a region of the brain that helps with speech production. People with Broca’s dysphasia usually find it difficult to form words and sentences. They may also speak with difficulties or not at all. They usually understand what others say better than their ability to speak.
Transcortical dysphasia
Transcortical dysphasia, also known as transcortical aphasia, is the least common type of dysphasia. It is also known as isolation dysphasia. It affects the nerve fibers that transmit information between the brain’s language centers, and other centers that integrate and process subtle aspects of communication. These usually include facial expressions, emotion, and tone of voice.
Transcortical dysphasia can be divided into three categories, including;
- Transcortical sensory dysphasia
- Transcortical motor dysphasia
- Mixed transcortical dysphasia
Wernicke’s dysphasia
Wernicke’s dysphasia, also known as Wernicke’s aphasia, occurs when a part of the brain, known as Wernicke’s area, is affected. Wernicke’s area [7] is a part of the brain that helps you understand the meaning of language and words. People with this condition can speak fluently, but their use of nonsensical irrelevant words and phrases can make what they say incomprehensible. They may also find it difficult to understand spoken languages.
Anomic dysphasia
Anomic dysphasia, also known as anomic aphasia, is a less severe type of dysphasia. People with this disorder usually find it difficult to recollect certain words, such as names. When they find it difficult to remember a word, they might pause, use gestures, or substitute a general word or description.
Conduction dysphasia (also known as conduction aphasia)
Conduction dysphasia is one of the rarest receptive types of dysphasia. People with this disorder can understand and produce speech, but may find it difficult to repeat it.
Global type
Global dysphasia, also known as global aphasia occurs due to a widespread damage to the brain’s language centers. People with this type of dysphasia usually find it difficult to express and understand language.
