まとめ
本研究では、虚血性脳卒中患者を対象とした初のアジア睡眠データベースであるiSLEEPSデータセットを紹介します。睡眠呼吸障害(SDB)の有病率が高いことが示され、今後の研究に役立ちます。
科学分野:
- 神経学
- 睡眠医学
- データサイエンス
背景:
- 睡眠障害は虚血性脳卒中生存者において一般的であり、神経回復および認知機能に影響を与えます。
- 睡眠呼吸障害(SDB)は、この集団において頻繁に見られる併存疾患です。
- 脳卒中特異的な睡眠データの欠如は、これらの相互作用の研究を妨げています。
研究 の 目的:
- 虚血性脳卒中患者の睡眠分析のためのポリソムノグラフィーデータセット(iSLEEPS)を導入すること。
- 脳卒中研究のための包括的で注釈付きの睡眠データベースを提供すること。
- アジアの脳卒中コホートにおけるSDBの有病率を調査すること。
主な方法:
- インドの虚血性脳卒中患者から100件の夜間ポリソムノグラフィー(PSG)記録を収集しました(2018年9月~2021年12月)。
- AASM(2017)ガイドラインに従って、睡眠段階、呼吸イベント、四肢運動、および酸素飽和度低下を専門家が注釈付けしました。
- 自動睡眠段階分類のために深層学習モデル(LSTM、Transformer、CNN)を適用しました。
主要な成果:
- iSLEEPSデータセットには、100人の脳卒中患者の詳細なPSGデータと臨床指標が含まれています。
- 研究コホートにおいてSDBの高い有病率が観察されました。
- Long Short-Term Memory(LSTM)モデルは、74.70%の自動睡眠段階分類精度を達成しました。
結論:
- iSLEEPSデータセットは、脳卒中睡眠研究における重要なギャップに対処します。
- このリソースは、脳卒中-睡眠病態生理学の研究を促進します。
- 虚血性脳卒中後の睡眠障害の包括的な分析をサポートします。

Insufficient Sleep and Sleep Deprivation
962
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Stages of Sleep
1.5K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Understanding Sleep
1.6K
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Sleep Apnea
591
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Sleepwalking and Sleep Talking
1.0K
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Substance Use Disorders Affecting Sleep
462
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
