Dysarthria is a speech disorder that occurs when the muscles used for speaking are weak or difficult to control. This condition can result from various neurological disorders, such as stroke, Parkinson's disease, or multiple sclerosis. People with dysarthria may have slurred or slow speech, making it hard for others to understand them. Treatment for dysarthria often involves speech therapy, where a speech-language pathologist helps individuals improve their communication skills. Techniques may include exercises to strengthen the speech muscles and strategies to enhance clarity. In some cases, assistive devices may also be used to aid communication.
