Objective:
To study the effect of therapeutic hypothermia on the sleep quality of patients in the early recovery period of ischemic stroke (IS).
Material And Methods:
The study included 32 patients in the early recovery period of IS. The test group included 22 patients (10 with IS in the vertebral-basilar system (VBS) and 12 with IS in the carotid system), and the control group included 10 patients (5 with IS in the VBS and 5 with IS in the carotid system). Control group patients received drug therapy, physiotherapy (magnetic therapy and electrotherapy), exercise therapy, and massage. Treatment in the test group also included craniocerebral hypothermia (CCH); 10 daily sessions of 90 min. Non-invasive radiothermometry was used to measure cerebral cortical temperature.
Results:
After CCH, the test group showed a statistically significant decrease in cerebral cortical temperature compared to the control group (p<0.015). Of note, the test group showed a statistically significant decrease in cerebral cortical temperature only in patients with IS in the VBS (p<0.001). It was shown that rehabilitation treatment with CCH significantly improved sleep efficiency, increasing the total sleep amount from 263 [101; 401] to 327 [181; 435] minutes, the sleep efficiency index from 51 [18; 72.6] to 62.3 [46; 85.3] %, the N2-stage of sleep from 25.6 [15.7; 36.9] to 29.0 [22; 42.9] %, and reducing the wake time during sleep from 40 [13; 57] to 34.5 [11; 44] % (p<0.05). Improved sleep quality in the test group was observed in patients with IS in the VBS. Sleep efficiency was unchanged in the control group.
Conclusion:
Thus, the data obtained support the relationship between brain temperature and sleep processes. With a decrease in brain temperature, sleep quality improves.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
