Chronic insomnia is linked to significant cognitive deficits and emotional alterations, particularly in individuals with a hereditary vulnerability. These issues impact attention, memory, and exacerbate anxiety-depression comorbidities.
Area of Science:
- Neuroscience
- Psychiatry
- Sleep Medicine
Background:
- Limited understanding of cognitive and emotional changes in chronic insomnia.
- Chronic insomnia involves complex etiological factors including vulnerability and heritability.
Purpose of the Study:
- To review current knowledge on cognitive deficits and emotional alterations in chronic insomnia patients.
- To explore the role of vulnerability, stress coping, and emotional regulation in insomnia.
Main Methods:
- Literature review of insomnia etiology and pathophysiology.
- Analysis of predisposing, precipitating, and maintaining factors.
- Examination of cognitive and emotional phenotypes in insomnia.
Main Results:
- Vulnerability to insomnia linked to non-adaptive stress coping and emotional internalization.
- Individuals with <6 hours of sleep show significant cognitive deficits (attention, memory).
- High comorbidity observed between insomnia and anxiety-depression.
Conclusions:
- Insomnia vulnerability is hereditary and involves hyperactivation disrupting sleep.
- Cognitive deficits suggest prefrontal dysfunction in severe insomnia.
- Insomnia and anxiety-depression have a bidirectional, intensifying relationship.
