Network analysis of emotional symptoms and cognitive function changes in primary insomnia

Area of Science:

• Neuroscience
• Psychiatry
• Sleep Medicine

Background:

• Primary insomnia is a prevalent disorder with diverse symptoms and consequences.
• Chronic sleep disturbances are linked to increased risk of anxiety, depression, and cognitive deficits.
• Understanding the interplay between emotional state and cognitive function in insomnia is crucial.

Purpose of the Study:

• To investigate the relationship between emotional changes and cognitive dysfunction in primary insomnia patients.
• To identify factors influencing the development and severity of primary insomnia.

Main Methods:

• Study included 40 primary insomnia patients and 48 healthy controls.
• Utilized Pittsburgh Sleep Quality Index, Montreal Cognitive Assessment, and Hamilton Anxiety/Depression Scales.
• Employed t-tests, chi-square tests, Pearson correlation, and network analysis for data examination.

Main Results:

• Primary insomnia patients showed significantly impaired immediate and delayed memory compared to controls.
• Naming and language abilities were significantly lower in the insomnia group.
• Higher Pittsburgh Sleep Quality Index scores correlated positively with anxiety and depression symptoms.

Conclusions:

• A significant correlation exists between emotional symptoms and cognitive dysfunction in primary insomnia.
• Anxiety and depression levels are positively associated with the degree of cognitive impairment in these patients.
