Sectiоn 6: Cаse Study 2 The next 5 questiоns refer tо the following informаtion (cаse also provided under Section 6 in paper exam). --- A 66-year-old man was referred for a speech evaluation by a neurologist to “see if there were any hints in his speech as to the type of problem he has”. When the patient comes to your office, you note that he has somewhat decreased facial expression, and doesn’t blink very often. During your intake conversation, you note that he has: Equivocally fast speech rate Slightly quiet, hoarse voice Occasional repeated phonemes at the beginning of words Slightly decreased intelligibility, especially near the ends of sentences. You then conduct an oral mechanism exam. You note: Symmetrical face with defined nasolabial folds Mild tremulousness of tongue, lips, and jaw during sustained postures Good strength when resisting tongue and cheek pressure Slightly decreased palatal elevation during repeated “ah” You then ask the patient to complete the DDK tasks. You note: Accelerated rate during AMRs Normal rate during SMRs Decreased articulatory distinction between consonant and vowel intervals You then ask the patient to say ah as long as they possibly can. You observe: 12 seconds sustained voicing, but quiet Mild vocal flutter You asked the patient to take a deep breath and try to produce ah as loud as they can. He produces a noticeably louder ah, but still can’t sustain it for very long.
