The impact of olfactory dysfunction on interoceptive awareness.

Krajnik J, Kollndorfer K, Notter LA, Mueller CA, Schöpf V - Psychophysiology (2014)

Bottom Line: Interoception is known as the awareness of one's body or the sense of the condition of the body; more precisely, this construct is defined as the processing, representation, and perception of the internal physical state.Interoceptive awareness was predicted by odor detection threshold, as well as the duration of olfactory loss in patients who suffered from reduced olfactory function-the longer the olfactory impairment, the worse the perception of bodily signals.The results of this study will significantly contribute to the basic understanding of the multifaceted effects of olfactory alterations.

Box plot diagram depicting data distribution of BDI scores of the two groups, olfactory dysfunction and normosmics. Due to incomplete BDI data of the olfactory dysfunction group, 53 patients (41 anosmics, 12 hyposmics) were compared to 16 healthy controls. Associated mean BDI scores (M) and standard deviation scores (SD) are represented below each group.

Figure 2: Box plot diagram depicting data distribution of BDI scores of the two groups, olfactory dysfunction and normosmics. Due to incomplete BDI data of the olfactory dysfunction group, 53 patients (41 anosmics, 12 hyposmics) were compared to 16 healthy controls. Associated mean BDI scores (M) and standard deviation scores (SD) are represented below each group.

Mentions: With regard to the known impact of olfactory impairment on the BMI and depressive symptom scores obtained by BDI, Mann-Whitney tests were executed for both groups. While BMI scores tended to differ between normosmics (median = 22.9) and subjects with reduced olfactory function (median = 25.0) U = 390, z = −1.93, p = .054, a significant difference between the groups (norm: median = 1.5; olf dys: median = 4.0) for depressive symptoms, U = 268, z = −2.23, p = .026 (see Figure 2) was observed.
