what diseases cause slurring of speech
Slurred speech is the result of weakened or uncoordinated muscles within the throat or mouth. All of the aforementioned ailments can cause these types of speech impairment and muscular issues, states Mayo Clinic. Neuromuscular diseases, which affect the nervous system and the muscles, are often causes of dysarthria. Multiple sclerosis, cerebral palsy, muscular dystrophy and myasthenia gravis are all known to cause dysarthria. Additionally, face or neck trauma or surgery affecting the tongue or voice box may also cause slurred speech, according to MedlinePlus.
