causes of flaccid dysarthria

Dysarthria (also called slurred speech) involves disturbances in control over speech muscles.Thus, dysarthria is grouped in the category of motor speech or speech motor disorders.Dysarthria occurs due to impairment or damage to the nervous system (brain, spinal cord, nerves in the body). The hallmark of flaccid dysarthria is difficulty pronouncing consonants. People with this condition may experience the following symptoms: Hyperkinetic dysarthria occurs as a result of damage to parts of the brain that doctors refer to collectively as the basal ganglia.
