What condition is characterized by palpitations at night and poor memory?

The condition characterized by palpitations at night and poor memory aligns well with Heart Blood deficiency. In Traditional Chinese Medicine (TCM), the Heart is not only responsible for circulation but is also considered the residence of the mind (Shen). When there is a deficiency of Heart Blood, there is often insufficient nourishment to support both the physical functions of the heart and the mental faculties. This can lead to symptoms such as palpitations, particularly noticeable during quieter times like at night, as well as cognitive issues including poor memory and concentration.

Heart Blood deficiency reflects a lack of substance that nourishes the Heart, which can ultimately lead to feelings of anxiety, insomnia, and a general sense of weakness or fatigue. The nourishing aspect of Heart Blood is crucial, and its deficiency can affect emotional well-being as well as cognitive function.

In contrast, the other conditions, while potentially exhibiting some similar symptoms, do not specifically correlate with the combination of nighttime palpitations and poor memory. For instance, each condition has distinct attributes that focus on different organ systems and associated symptoms, making Heart Blood deficiency the most fitting choice for the symptoms described.
