Dysarthria

From WikiMD's Wellness Encyclopedia

(Redirected from Dysarthric)

Dysarthria encompasses a collective group of motor speech disorders stemming from abnormalities in the strength, speed, range, steadiness, tone, or accuracy of movements required for the control of the respiratory, phonatory, resonatory, articulatory, and prosodic aspects of speech production. The primary cause is damage to the brain or nerves that control the muscles involved in speech.

Characteristics of Dysarthria[edit | edit source]

Dysarthria is marked by a variety of speech changes, which can be mild to severe, depending on the extent and location of the neurological impairment. Changes can include slurred or slow speech, limited tongue, lip, and jaw movement, abnormal intonation, changes in voice quality, and difficulty maintaining regular speech volume.

Underlying Causes and Classifications[edit | edit source]

Dysarthria can result from neurological conditions that affect the motor control of speech muscles. These may include stroke, brain injury, Parkinson's disease, Amyotrophic lateral sclerosis (ALS), Multiple sclerosis, Huntington's disease, and Cerebral palsy.

Dysarthrias are typically classified based on the primary location of neurological damage, such as flaccid dysarthria (lower motor neuron damage), spastic dysarthria (upper motor neuron damage), ataxic dysarthria (cerebellar damage), and hypokinetic or hyperkinetic dysarthria (basal ganglia damage).

Diagnosis and Management[edit | edit source]

The diagnosis of dysarthria involves a thorough medical history, neurological examination, and specific speech and language assessments. These evaluations help identify the type of dysarthria and develop an appropriate treatment plan.

Management often involves speech and language therapy. Techniques can include exercises to improve speech muscle strength and coordination, breath control techniques, and strategies to make speech clearer, such as speaking slowly or in a louder voice.
