Sleep duration and brain-derived neurotrophic factor correlate with cognitive impairment in insomnia

Takeaway

  • This is the first study to assess the role of brain-derived neurotrophic factor (BDNF), a mediator in neuroplasticity, in the cognitive function of people with different degrees of insomnia.

Why this matters

  • BDNF could be a useful biomarker for the cognitive impairment associated with short sleep duration in insomnia.
