Insomnia may be related to cerebrovascular diseases, but clinical insomnia is mostly considered to be due to psychological or physiological factors. Insomnia is mostly caused by psychosocial factors, such as experiencing blows, anger and fire, and high work pressure, which can easily cause depression, tension, anxiety and other states. If the patient is in a state of high tension and rumination for a long time, it may be manifested as irritability, tension, thoughtfulness and insomnia over time. In addition, physiological factors can also lead to insomnia, such as hunger before bedtime, too full before bedtime, too tired, too excited, etc. Meanwhile, cerebrovascular diseases can also lead to insomnia, such as insufficient blood supply to the brain can make patients feel dizzy and headache frequently, which can lead to poor sleep quality and may cause insomnia. Insomnia is not a specific symptom of cerebrovascular disease, so patients cannot assume the presence of cerebrovascular disease just because of insomnia. If cerebrovascular disease is suspected, patients can consult a neurologist.
