  1. Mixed dysarthrias are most commonly composed of how many types of dysarthrias?
    2 dysarthrias is most common, then 3, 4, 5, and 6. All six is rare but possible.
  2. Mixed dysarthria can occur when neurological damage extends into _____ or more parts of the nervous system?
  3. What are the two things that determine which characteristics of the single dysarthrias appear in a particular diagnosis of mixed dysarthria?
    location and extention of the neurological damage
  4. Which will SLPs see more cases of... mixed dysarthria or pure dysarthria?
    mixed dysarthria
  5. What determines the speech characteristics of mixed dysarthria?
    It's a combination of the characteristics found in the pure dysarthrias.
  6. A patient's neurological damage is restricted to a single anatomical portion of the motor system. This results in which type of dysarthria?
    Pure dysarthria
  7. True or False: In most instances of mixed dysarthria, one of the dysarthric components will be much more noticeable than the others.
    True-however it is posible for each component of a mixed dysarthria to appear more or less equal in prominence
  8. The prominence of one dysarthric characteristic over another is usually the result of...what?
    the severity and extent of the neurological damage
  9. True or False: the relative prominence of one dysarthric component over another can change over time.
    True. Example: ALS first results in flaccid dysarthia but as the disease progresses, it affects upper motor neurons as well and can become a mixed dysarthria.
  10. Etiologies of Mixed Dysarthia would include:
    Multiple Sclerosis, Multisystems Atrophy (which includes Shy-Drager Syndrome, Progressive Supranuclear Palsy, and Olivopontocerebellar Atrophy), Amyotrophic Lateral Sclerosis, Wilson's Disease, and Freidrich's Ataxia
  11. What is Multiple Sclerosis? (MS)
    A progressive disease in which the myelin covering of axons degenerates.
  12. What is the most common demyelinating disease?
    Multiple Sclerosis (MS)-occurs in about 100 per 100,000 of the population in the US and UK.
  13. What is the etiology of Multiple Sclerosis (MS)?
    The etiology of Multiple Sclerosis (MS) is unknown.Some evidence suggests that it may be an immunological disorder that is triggered by a virus.

    Multiple Sclerosis (MS) affects more women than men-a ratio of 1.7 to 1.
  15. When does Multiple Sclerosis (MS) first appear in individuals?
    In their 30s.
  16. True or False: Multiple Sclerosis (MS) does not directly damage the axon.
    True-the axon remains intact but the destruction of the protective myelin affects its function by slowing or stopping its ability to conduct neural impulses.
  17. What are the symptoms of Multiple Sclerosis (MS)?
    Visual disturbances (among the most common), chronic feelings of tiredness, weakness in the limbs, disturances of sphincter muscle control, dysarthria, numbness, burning sensations, itching, tingling, depression, and mild dementia (in advanced cases)
  18. True or False: the course of Multiple Sclerosis (MS) doesn't vary much from patient to patient.
    False-40% go through relapsing and remitting occurrences of their symptoms during the early stages of the disease, then begin a steady and slow progression of more significant symptoms. 20-30% maintaina relapsing and remitting course for the duration of their lives, 10-20% have a steady progression from the very outset, and 20% experience only one or two relapsing and remitting occurrences of symptoms and are otherwise unaffected by the disease.
  19. True or False: Most individuals with Multiple Sclerosis (MS) demonstrate obvious motor speech deficits.
    False-although MS can cause many types of dysarthia, most individuals with this disease do NOT demonstrate obvious motor speech deficits.

  55. A rare hereditary disease that prevents the normal metabolism of dietary copper-instead of being excreted, excessive amounts of copper are deposited in the corneas of the eyes, kidneys, liver, and brain (especially in the basal ganglia).
    Wilson's Disease.
  56. When do the first signs of Wilson's Disease appear?
    In the teens or twenties
  57. What are the symptoms of Wilson's Disease...broken down into early and late?
    Early-clumsiness, mild decreases in cognitivite abilities and subtle personality changes. Later-rigidity, bradykinesia, tremor, limb ataxia, dementia, dysphagia, and dysarthria. Also, dystonic and choreic movements. Emotional lability, severe depression, mania, behaviors having schizophrenic characteristics.
  58. True or false-there is no treatment for people with Wilson's Disease.
    False-effective treatments are available for nearly all individuals with this disease-most common treatment is oral dosages of penicillamine. It reduces the copper deposits in the body and often leads to dramatic improvements in the symptoms. Permanent damage can occur if not treated quickly-can be fatal within 2-3 years of first symptoms if untreated. Death usually occurs from liver failure.
  59. What are the three most prominent speech errors in people with Wilson's Disease?
    Reduced stress, monopitch and monoloudness.
  60. What is the most noticeable dysarthria in Wilson's Disease?
    Hypokinetic dysarthria.Also has speech errors that are characteristic of ataxic and spastic dysarthria... might appear alone, reflecting a pure rather than mixed dysarthria.
  61. An inherited, progressive disorder that causes neuron degeneration in the cerebelllum, brainstem, and spinal cord.
    Friedreich's ataxia-rare disorder that first becomes evident when individuals are ni their 20s, untreatable, and usually fatal within 10-15 years of the initial appearance of the symptoms, usually the result of heart failure or coma.
  62. Early symptoms of Friedreich's ataxia are...
    unsteadiness and clumsiness, with ataxia being present in the movements of the arms and legs. Mild dysarthria. As the disorder progresses...weakness and muscle atrophy in the arms and legs, visual deficits and SNHL can occur. They eventually develop dementia.

    Ataxic dysarthria...other types are possible though, especially spastic dysarthria.
  64. What is the most common mixed dysarthria associated with Friedreich's ataxia?
    Ataxic-spastic mixed dysarthria.
  65. Which of the following diseases are/are NOT characterized by dementia? (MS, Shy-Drager Syndrome, PSP,Olivopontocerebellar Atrophy, ALS, Wilson's Disease, Freidreich's Ataxia)

    The general rule in treating mixed dysarthria is to first treat the component that is most severely affecting speech production.
  67. What order should the elements of mixed dysarthria be treated when they equally affect speech production?
    1st-respiration, 2nd-resonation, 3rd-phonation, 4th-articulation, 5th-prosody. The reason for this is based on how the different components of speech support each other.
  68. What are the five communicative stages that a patient with ALs will pass through as the disease progresses & what happens in them?
    • 1. No detectable speech disorder-pts and family given general facts about the communication deficits associated with ALS. Start learning basics of Aug Comm systems.
    • 2. Obvious speech Disorder with Intelligible Speech-active SLP involvement advising pts and family on how tom aximize the intelligibility of the patient's speech, introduction to voiec amplification. preliminary steps of choosing aug comm systems should be started.
    • 3. Reduction in Speech Intelligibility-try to help increase of maintain a pt's intelligibility-with things with reduced rate of speech, breath group duration, palatal life, etc.
    • 4. Residual Natural Speech and Augmentative Communication-pts rely heavily on aug comm device to supplement residential intelligible speech. Aug comm now becomes the primary method of communication-family and friends trained on how to best communicate with pt.
    • 5. Loss of useful Speech-depend almost exclusively on aug com systems. a collection of low-tech aug procedures may also be used like yes/no, eye blinks, eye-pointing.
