Just as the term "articulation" can mean either "speech" or "joint movement", so is the combining form of arthr- the same in the terms "dysarthria", "dysarthrosis", and "arthropathy"; the term "dysarthria" is conventionally reserved for the speech problem and is not used to refer to arthropathy, whereas "dysarthrosis" has both senses but usually refers to arthropathy. Causes
There are many potential causes of dysarthria. They include toxic, metabolic, degenerative diseases, traumatic brain injury, or thrombotic or embolic stroke.Degenerative diseases include parkinsonism, amyotrophic lateral sclerosis (ALS), multiple sclerosis, Huntingtons disease, Niemann-Pick disease, and Friedreichs ataxia. Toxic and metabolic conditions include: Wilsons disease, hypoxic encephalopathy such as in drowning, and central pontine myelinolysis.These result in lesions to key areas of the brain involved in planning, executing, or regulating motor operations in skeletal muscles (i.e. muscles of the limbs), including muscles of the head and neck (dysfunction of which characterises dysarthria). These can result in dysfunction, or failure of: the motor or somatosensory cortex of the brain, corticobulbar pathways, the cerebellum, basal nuclei (consisting of the putamen, globus pallidus, caudate nucleus, substantia nigra etc. ), brainstem (from which the cranial nerves originate), or the neuromuscular junction (in diseases such as myasthenia gravis) which block the nervous systems ability to activate motor units and effect correct range and strength of movements.Causes:
Brain tumor
Cerebral palsy
Guillain–Barré syndrome
Hypothermia
Idiopathic intracranial hypertension (formerly known as pseudotumor cerebri)
Lyme disease
Stroke
Tay–Sachs disease, and late-onset Tay–Sachs disease (LOTS)
Transient ischemic attack, a mini stroke

Diagnosis
Classification
Dysarthrias are classified in multiple ways based on the presentation of symptoms.
Regularity of practice, and when to practice, are the main issues in PML treatments, as they may determine the likelihood of generalization of new motor skills, and therefore how effective a treatment is.Augmentative and alternative communication (AAC) devices that make coping with a dysarthria easier include speech synthesis and text-based telephones. These allow people who are unintelligible, or may be in the later stages of a progressive illness, to continue to be able to communicate without the need for fully intelligible speech. See also
