Musical tasks targeting preserved and impaired functions in two dementias.

Halpern AR, Golden HL, Magdalinou N, Witoonpanich P, Warren JD - Ann. N. Y. Acad. Sci. (2015)

Bottom Line: Behavioral and neural evidence confirms involvement of perceptual networks in imagery, and these are relatively spared in early stages of the illness.Thus, we expected patients to have relatively intact imagery in a mental pitch comparison task.We probed inhibitory skills by asking for a speeded pitch or timbre judgment when the irrelevant dimension was held constant or also changed.

fig03: Accuracy in deciding if the second note is higher or lower than the first in perceived and imagined familiar songs, in Alzheimer's disease (AD) patients and controls. *P < 0.05.

Mentions: The dependent measure was d ′. Patients did not differ significantly from controls in age (t = −1.43, P = 0.16), gender distribution (χ2 = 0.72, P = 0.40), or years of musical training (t = −1.7, P = 0.11). Years of musical training significantly affected d ′ scores (β = 0.20, CI = 0.1–0.3, P = 0.01), but age did not (β = 0.04, CI = −0.05 to 0.1, P = 0.39). Condition had a significant effect on d ′ scores (β = −1.56, CI = −2.2 to −0.9, P < 0.001), as did group (β = −1.15, CI = −2.3 to −0.02, P = 0.046). There was no interaction between condition and group (F(1,25) = 0.77, P = 0.39). However, as an exploratory analysis, we compared the groups on both tasks. The patients were clearly equivalent to the controls on imagery but were less accurate than the controls in the perceptual version (which was the easier task; Fig.3).
