At present, about 1/5 of stroke patients in China worldwide, of which about 56% -68% of patients experience insomnia after onset, and the proportion of insomnia after ischemic stroke is higher than that after hemorrhagic stroke. The daytime functional impairment caused by insomnia, such as anxiety and depression, can exacerbate the negative emotions and cognitive impairment of stroke patients, and cause significant burden on their families and society. Therefore, improving insomnia after stroke is crucial. Western medicine treatment mainly relies on sedation and hypnosis, which may have certain side effects or dependencies, while traditional Chinese medicine treatment has outstanding advantages.
Traditional Chinese Medicine believes that insomnia after stroke is a comorbidity, which includes both "stroke" and "insomnia". Its etiology and pathogenesis are complex, and it may occur due to liver depression turning into fire, disturbing the mind and spirit; Or it may occur due to liver and kidney yin deficiency and loss of mental and spiritual nourishment. Among them, patients with insomnia after stroke are often diagnosed with liver stagnation and blood deficiency syndrome. According to the Treatise on Cold Damage, Suanzaoren Tang can relieve depression, relieve annoyance, nourish blood and calm the mind. It also has phlegm and stasis stagnation in the meridians after stroke. Adding products that promote blood circulation, remove blood stasis, and invigorate the spleen and phlegm can form a modified Suanzaoren Tang. Clinical reports have shown that liver stagnation and blood deficiency syndrome are more common. Suanzaoren Tang has a significant therapeutic effect on insomnia by clearing heat, eliminating annoyance, nourishing blood, and calming the mind. However, due to the pathogenic factors of excessive phlegm and blood stasis after stroke, which may be biased towards liver depression or blood deficiency, Suanzaoren Tang is often used for reducing symptoms during clinical practice.
