Exam 10: Neurogenic Disorders of Speech in Children and Adults

In addition to dysarthria,children with cerebral palsy may have feeding problems because

Flaccidity refers to muscle weakness.

Shaun's speech is unintelligible.All aspects of his speech production are impaired including articulation,resonance,phonation and respiration.His speech is characterized by imprecise consonant articulation,monopitch,reduced stress,harsh voice quality,strangled voice quality,pitch breaks and hypernasality.Shaun most likely is exhibiting

Brian's speech is characterized by imprecise consonant articulation,slow labored speech,monopitch,low pitch,monoloudness and hypernasality.His speech-language pathologist wants to assist Brian with monitoring his attempts to vary his pitch and loudness as well as increase his motivation to participate in speech therapy.She decides to use

Researchers have identified eight types of dysarthria.

Casey is four years old.She presents with a phonemic inventory of 5 consonants and 5 vowels,and inconsistent substitution,omission and distortion errors involving these speech sounds.The frequency of her speech sound errors increase as word length increases.She also exhibits monopitch and monoloudness.Her likely diagnosis is

The most frequently occurring type of cerebral palsy is spastic cerebral palsy.

Greene has Tourette's Syndrome.He experiences brief,recurrent compulsive movements.He also has vocal tics that include coughing,and grunting.Stuttering-like repetitions,echolalia,and coprolalia characterize his speech.His type of dysarthria is referred to as

Shaun's condition was probably caused by damage to the brain that may have occurred

Six year old Brian has cerebral palsy resulting from bilateral upper motor neuron damage.He exhibits hypertonia,hyperreflexia,dysarthria,dysphonia,bilateral hemiparesis,and drooling.Brian has been diagnosed with

The most frequently occurring dysarthria is spastic dysarthria.

Shaun was born with the inability to coordinate and control motor movement and posture.Specifically,Shaun exhibits involuntary and uncontrolled movements of his arms and legs,hands and feet.His purposeful movements are slow and writhing.He also exhibits distorted facial patterns and drooling.Shaun's diagnosis is probably

Fasciculations refer to voluntary twitches of individual muscles.

Shaun's hypernasality most likely results from

Developmental dysarthria is most commonly associated with children with cleft lip and palate.

Apraxia of speech is a well-understood neurogenic speech disorder.

Many children with DAS make slow progress in speech therapy.

Myasthenia Gravis is a neurological disorder in which the patient experiences muscle weakness that progressively worsens with activity.The effort the patient puts forth during speech eventually leads to muscle fatigue resulting in hypernasality,onset of dysphonia,reduced speech intelligibility and reduced loudness.The type of dysarthria manifested by a patient with myasthenia gravis is most likely to be

Neurogenic speech disorders are caused by damage to the nervous system.
