Key result
Panic and phobia symptoms in elderly insomnia patients were negatively correlated with normalized high-frequency power (β=-0.59, p<0.01), suggesting decreased parasympathetic nervous system activity.

Panic symptoms in elderly insomnia patients are associated with reduced parasympathetic nervous system activity as measured by heart rate variability.
Hypothesis-generating for autonomic imbalance in elderly insomnia with panic symptoms; prospective studies needed before clinical adoption.
Objective: This study investigated the association between anxiety symptoms in elderly insomnia patients and heart rate variability (HRV) parameters. Methods: In total, 46 elderly patients (67.91±5.61 years old, 11 males, 35 females) were enrolled. The Pittsburgh Sleep Quality Index, Beck Anxiety Inventory, Albany Panic and Phobia Questionnaire (APPQ), Penn State Worry Questionnaire, and Liebowitz Social Anxiety Scale were used to measure sleep quality and anxiety. Resting-state HRV was also obtained. The associations between anxiety measures and HRV were analyzed. Results: Female sex was related to higher normalized high-frequency (HF norm) power (β=0.32, p=0.04). The APPQ score was negatively correlated with the HF norm (β=-0.59, p<0.01). Age was negatively correlated with low-frequency power/high-frequency power (LF/HF) ratio (β=-0.33, p=0.04). Female sex was correlated to lower LF/HF ratio (β=-0.36, p=0.02). The APPQ score was positively correlated with LF/HF ratio (β=0.68, p<0.01). Conclusion: Panic symptoms in elderly insomnia patients were negatively correlated with parasympathetic nervous system activity.

Seo et al. (2022) conducted a cross-sectional in Insomnia (n=46). Panic and phobia symptoms (APPQ score) was evaluated on Correlation between Albany Panic and Phobia Questionnaire (APPQ) score and normalized high-frequency (HF norm) power (β=-0.59, p=<0.01). Panic and phobia symptoms in elderly insomnia patients were negatively correlated with normalized high-frequency power (β=-0.59, p<0.01), suggesting decreased parasympathetic nervous system activity.
