30. How might one of the common deficits associated with right hemisphere disorders show up in the everyday social communication of an individual? Please illustrate with your own example.

31. Explain the diagnostic criteria for identifying primary progressive aphasia (PPA).

Mesulam (2001), to be conferred a diagnosis of PPA, an individual’s language disturbance must have had a gradual onset and should be the initial and primary symptom for at least the first 2 years and must remain the most prominent impairment throughout disease progression. In the early stages of the disease, any disruptions in daily life should be related to language problems. PPA diagnosis is not appropriate if visuospatial processing impairments, episodic memory deficits, or behavioral disruptions are prominent in the initial stages of the disease or if deficits can be clearly linked to stroke, brain tumor, traumatic brain injury, or psychiatric conditions.

32. On the next page, please read the descriptions of three evidence-based management strategies for dementia. These were not covered in your textbook, but you may still find them useful when working with this population. The description of each approach was taken from the ASHA Dementia Practice Portal.  For the last essay question, please select any one of these three approaches, and describe how you would maximize treatment effectiveness using one or more of the nine “Evidence-Based Features of Successful Interventions for Persons with Dementia” listed in your textbook.

1.Repeated and rich presentation of target information

2.Contexts for learning by doing and multiple opportunities to practice generating target responses

3.Ways to capitalize on relatively spared cognitive capacities (such as sustained attention)

4.Cognitive stimulation to activate experience-dependent neuroplasticity

5.Task formats that reduce the likelihood of errors during initial learning and increase the chance of early success

6.Exposure to personally meaningful, tangible sensory stimuli

7.Structured cues or cueing hierarchies that support information retrieval

8.Opportunities for creative and symbolic activity (e.g., using art, music, gardening)

9.Experiences that offer community engagement, intergenerational programming, and regular physical activity

                                                           iii.     Reduced use of emotionally-laden words

h.     Acropodia types: not universal, subgroups are emerging based on characteristic and severity

                                                              i.     Linguistic aprosodia:

                                                            ii.     Receptive linguistic aprosodia: impaired ability to interpret prosodic features that indicate that a question has been asked

1.     Expressive linguistic aprosodia: impaired ability to use prosodic features to indicate that a question is being asked

i.       Affective or emotional aprosodia:

                                                              i.     Receptive emotional aprosodia: impaired ability to interpret mood or emotion through prosodic features

                                                            ii.     Expressive emotional aprosodia: impaired ability to convey mood or emotion through prosodic features

30. How might one of the common deficits associated with right hemisphere disorders show up in the everyday social communication of an individual? Please illustrate with your own example.

31. Explain the diagnostic criteria for identifying primary progressive aphasia (PPA).

Mesulam (2001), to be conferred a diagnosis of PPA, an individual’s language disturbance must have had a gradual onset and should be the initial and primary symptom for at least the first 2 years and must remain the most prominent impairment throughout disease progression. In the early stages of the disease, any disruptions in daily life should be related to language problems. PPA diagnosis is not appropriate if visuospatial processing impairments, episodic memory deficits, or behavioral disruptions are prominent in the initial stages of the disease or if deficits can be clearly linked to stroke, brain tumor, traumatic brain injury, or psychiatric conditions.

32. On the next page, please read the descriptions of three evidence-based management strategies for dementia. These were not covered in your textbook, but you may still find them useful when working with this population. The description of each approach was taken from the ASHA Dementia Practice Portal.  For the last essay question, please select any one of these three approaches, and describe how you would maximize treatment effectiveness using one or more of the nine “Evidence-Based Features of Successful Interventions for Persons with Dementia” listed in your textbook.

1.Repeated and rich presentation of target information

2.Contexts for learning by doing and multiple opportunities to practice generating target responses

3.Ways to capitalize on relatively spared cognitive capacities (such as sustained attention)

4.Cognitive stimulation to activate experience-dependent neuroplasticity

5.Task formats that reduce the likelihood of errors during initial learning and increase the chance of early success

6.Exposure to personally meaningful, tangible sensory stimuli

7.Structured cues or cueing hierarchies that support information retrieval

8.Opportunities for creative and symbolic activity (e.g., using art, music, gardening)

9.Experiences that offer community engagement, intergenerational programming, and regular physical activity
