The Dysarthria is like a speech disorder, which is caused due to the weakness of the muscles. In this disorder, the person may have trouble understanding what you say.

3. Dysarthria vs Aphasia

Both dysarthria and aphasia can affect any person’s ability to produce speech but on the other hand, their causes are different from each other.

Dysarthria is a term which is used for certain kind of disorders that can impact muscles used in speaking which includes the throat, lips, tongue, diaphragm, and vocal cords. There are several symptoms of dysarthria such as uneven starts and stops, drolling, irregular volume, breathing, and nasal speech, and many more.

Aphrasia can cause due to an injury to the brain. Its symptoms mainly depend on the severity and location of brain injury.

Usually, dysarthria describes a large group of the same related terms. Some people also prefer dysarthrias. Most of the people prefer the term dysphasia in place of aphasia. The prefix “a” means absence of ability, on the other hand, “dis” signifies a partial loss of ability. Therefore, both the terms dysphasia and aphasia are used interchangeably. Only there is one difference that dysphasia term is preferred in Ewhereasere as aphasia term is preferred in North America.
