Sleep disorders can be a warning sign of the risk of cerebral infarction. The three most common sleep-related issues associated with this risk include:

1. Sleep Apnea: Sleep apnea, especially obstructive sleep apnea, disrupts breathing during sleep, leading to low blood oxygen levels and increased strain on the cardiovascular system. This condition increases the risk of stroke and other cardiovascular problems.

2. Insomnia: Insomnia, or difficulty sleeping, can cause stress and negatively affect the cardiovascular system. Studies have shown that insomnia may be associated with an increased risk of stroke, although the exact mechanism needs further research.

3. Sleep-Related Movement Disorders: Disorders such as restless legs syndrome or periodic leg movements during sleep can disrupt sleep and affect the quality of rest. While the direct link to stroke requires more research, poor sleep quality can indirectly increase the risk of stroke.

Recognizing and treating these sleep disorders in a timely manner can help reduce the risk of stroke and improve quality of life.
