AI Article Synopsis
- This study explored the link between insomnia symptoms and the risk of death among stroke survivors using data from the Health and Retirement Study, focusing on participants over 50 with a history of stroke from 2002 to 2018.
- Out of 3,501 stroke survivors monitored for an average of 6 years, it was found that insomnia symptoms, particularly difficulties in initiating and maintaining sleep, were linked to a higher risk of mortality in young male stroke survivors, but no such link was found for females.
- The findings suggest that insomnia may significantly increase the risk of all-cause mortality in younger male stroke survivors, indicating a need for further research in this area, especially since these results were not
Article Abstract
Background: Insomnia is more frequently reported in stroke survivors but its independent role in mortality in stroke survivors is unknown. The purpose of this study was to investigate the association of insomnia symptoms with all-cause mortality among stroke survivors.
Methods: The Health and Retirement Study, a survey of Americans older than 50 years and their spouses of any age from 2002 to 2018 was used. Only participants with a history of stroke were included. The exposure variable of interest was insomnia symptoms including difficulty initiating sleep, difficulty maintaining sleep, waking up too early, and nonrestorative sleep. The outcome was all-cause mortality. Cox proportional hazards regression models were employed to investigate the association between insomnia symptoms and all-cause mortality.
Results: A total of 3,501 stroke survivors were included of which 55% were females. Over a mean follow-up of 6 years, 1,782 deaths occurred. Difficulty initiating sleep (HR = 1.87, 95% CI: 1.07, 3.25) and difficulty maintaining sleep (1.89, 95% CI: 1.09, 3.29) were associated with all-cause mortality only among male stroke survivors younger than 65 years old while nonrestorative sleep (HR = 1.31, 95% CI: 1.05, 1.62) was associated with all-cause mortality only among male stroke survivors aged 65 years and older. Furthermore, male stroke survivors younger than 65 years of age and older than 65 with insomnia symptom scores ranging from 5 to 8 (mean = 6.2) had a higher but statistically nonsignificant risk of all-cause mortality (HR = 1.56, 95% CI: 0.81, 3.01 and HR = 1.08 95% CI: 0.85, 1.38, respectively) compared to their counterparts without insomnia symptoms. There was no association between insomnia symptoms and all-cause mortality among female stroke survivors.
Conclusion: Insomnia symptoms were associated with an increased risk of death especially in male stroke survivors younger than 65 years of age. Future studies should explore the benefit of insomnia symptom management in stroke survivors.

Background: Post-stroke depression (PSD) negatively impacts the physical and mental well-being of stroke survivors. However, data on the prevalence and risk factors of PSD in African countries such as Cameroon are limited.
Aim: This study aims to determine the prevalence and factors associated with PSD among stroke survivors at a hospital in Cameroon and inform clinical practice.

Objectives The study aimed at estimating the triglyceride glucose (TyG) index in patients with ischemic stroke, exploring the correlation between the TyG index and the prognosis of ischemic stroke, and studying the clinical outcome in patients with acute ischemic stroke (AIS) in association with the TyG index. Methods An observational study was conducted on 105 patients with a history of AIS presenting within 24 hours. The TyG index was estimated, and the clinical outcome was studied.

The recent identification of Piezo ion channels demonstrating a mechano-sensitive impact on neurons revealed distinct Piezo-1 and 2 types. While Piezo-1 predominates in neurons linked to non-sensory stimulation, such as pressure in blood vessels, Piezo-2 predominates in neurons linked to sensory stimulation, such as touch. Piezo-1 and 2 have a major bidirectional impact on transient receptor potential (TRP) ion channels, and TRPs also impact neurotransmitter release.
