Anarthria
Anarthria is a speech disorder characterized by the loss of the ability to articulate words clearly due to impaired motor mechanisms of speech. This condition differs from aphasia, which impairs the ability to understand or produce speech at the level of the brain's language functions. Anarthria results from physiological problems, such as damage to the nerves or muscles involved in speaking.
People with anarthria have difficulty controlling the muscles used for speech, including the lips, tongue, and larynx, making their speech unclear or even impossible. It is important to note that in anarthria, cognitive functions such as language comprehension and thinking usually remain intact.
Anarthria has many possible causes, including stroke, traumatic brain injury, neurological diseases such as Parkinson's disease, and other disorders affecting the neuromuscular system.
