Damage to the cerebellum can manifest in any level of speech production.
True
Ataxic dysarthria is characterized by accurate force and range of motion in speech movements.
False
Perceptually, ataxic dysarthria is often described as a lack of accents by the listener.
False
The primary function of the cerebellum is to process visual information during speech production.
False
Ataxic dysarthria may present with atypical stress patterns in speech.
True
The cerebellum is responsible for the movements in speech production.
False
Cerebellar ataxia may lead to challenges with motor learning.
True
Ataxic dysarthria is characterized by undershooting movements in speech.
False
Dysmetria refers to a lack of coordination of movement with overshoot or undershoot of intended position.
True
Ataxic dysarthria may present with typical stress patterns in speech.
False
Unilateral Upper Motor Neuron Dysarthria is considered the most severe form of dysarthria.
False
Lesions in the indirect activation pathway are characteristic of ataxic dysarthria.
False
Damage to the cerebellum can manifest in any level of speech production.
True
Ataxic dysarthria is the most common type of motor speech disorder.
False
The cerebellum influences speech control primarily through connections to the direct activation pathway.
False
Lesions in the direct activation pathways can result in hyperactive stretch reflexes.
False
UMN damage is commonly caused by degenerative, inflammatory, and toxic-metabolic diseases.
False
Trauma is not a potential cause of UMN damage.
False
In ataxic dysarthria, phonation is often characterized by a decreased loudness.
False
Spasticity is a common symptom of lesions in the indirect activation pathway.
True
Mixed Dysarthria is characterized by any one of the components predominating over others.
True
________ processes sensory information from all over the body and integrates that information into execution of a movement
Cerebellum
Which structure is responsible for coordinating movement, planning motor activities, learning and remembering physical skills, and some cognitive abilities?
Cerebellum
The cerebellum has a dual ability to coordinate and modify planned and ongoing speech movements by the cerebellum.
The cerebellum has a dual ability to and planned and ongoing speech movements by the cerebellum.
You are assessing an individual with suspected dysarthria. The demonstrate difficulty coordinating voluntary movements, and coordinating the force of movements. They also have a broad-based gait and hypotonia of muscles. Which dysarthria type is likely?
Ataxic
An individual with Ataxic dysarthria will have a normal oral mechanism exam.
True

Non-speech AMRs
Which is the most mild form of dysarthria?
Unilateral Upper Motor Neuron
Which of the following is not a result of lesions in the direct activation pathway?
Spasticity
Which of the following is not a result of lesions in the indirect pathway

Irregular articulatory breakdowns
A patient complains that their speech sounds slurred, their lower face is drooping, drooling, and mild swallowing difficulty. Which dysarthria type is most likely?
Mixed
Which dysarthria type accounts for 27% of all dysarthrias?
Mixed
Learn about Ataxic Dysarthria, which accounts for 13.3% of motor speech disorders and 14.6% of all dysarthrias. It is caused by damage to the cerebellum, affecting respiratory, phonatory, resonatory, and articulatory levels of speech. Symptoms include atypical stress patterns, incoordination, and reduced muscle tone.
