Poor dissociation of patient-evaluated apathy and depressive symptoms.

Njomboro P, Deb S - Curr Gerontol Geriatr Res (2012)

Bottom Line: Research on the relationship between apathy and depression has, however, produced mixed results.Patient-rated, and not informant-rated apathy significantly correlated with depression.We discuss the implication of these results on the relationship between the two neuropsychiatric conditions and also in relation to the utility of patient self-evaluations in apathy.

ABSTRACT
Apathy has traditionally been conceptualised as part of depression. The appropriateness of this conceptualisation has now been questioned, with the realization that apathy constitutes a distinct neuropsychiatric condition, with separate rehabilitation and patient-care implications to depression. Research on the relationship between apathy and depression has, however, produced mixed results. One reason for this inconsistency may lie behind who does the apathy evaluation. In this study we investigated whether the relationship between apathy and depression would differ when apathy was evaluated by the patients or an informant. A total of 49 brain damaged patients were assessed on self- and informant-rated Apathy Evaluation Scales. The relationship between the apathy scores and depressive symptoms was then investigated. Patient-rated, and not informant-rated apathy significantly correlated with depression. We discuss the implication of these results on the relationship between the two neuropsychiatric conditions and also in relation to the utility of patient self-evaluations in apathy.

(Adopted from Goel and Grafman, 1995). Start states for 9 of the 10 ToH trials used in the study. The tenth trial (not included in the diagram) had a start state in which discs A to E were all placed on the right peg, and it was administered after the 9th trial.

fig1: (Adopted from Goel and Grafman, 1995). Start states for 9 of the 10 ToH trials used in the study. The tenth trial (not included in the diagram) had a start state in which discs A to E were all placed on the right peg, and it was administered after the 9th trial.

Mentions: The ToH puzzle provided a cognitive measure of executive function. Solving the puzzle requires the use of forward planning and capacities related to anticipatory, insightful means end problem-solving strategies. A series of 10 ToH trials of varying levels of difficulty were administered to each of the participants. The puzzle consisted of a flat wooden board with three vertical pegs of equal height and diameter fixed equidistantly from each other and five wooden disks (disks A, B, C, D, and E). On each of the 10 trials, the disks were placed in some predetermined arrangement on the pegs (start state), and participants had to rearrange the disks until they were all staked in a descending order according to size on the middle peg (the goal state; see Figure 1 below). Participant had to follow three rules: (a) only one disk could be moved at a time, (b) any disk not being moved had to remain on a peg, and (c) a larger disk could not be placed on top of a smaller disk. The number of trials successfully completed on the task provided the ToH score. For various reasons, scores on the ToH were obtained for 25 patients.
