Calligraphy training, a traditional cultural activity with a 3 000-year history, has recently been demonstrated to positively impact multiple cognitive functions in individuals with cognitive impairment. Research indicates that calligraphy training can enhance cognitive functions. Potential mechanisms through which calligraphy training influence cognitive function include functional reinforcement of the default mode network, co-activation of the visuomotor integration network, involvement of the frontoparietal executive control network, and modulation of neurotransmitter systems and molecular mechanisms underlying neural plasticity. Although existing studies provide preliminary evidence supporting the positive effects of calligraphy training on cognitive function in individuals with cognitive impairment, limitations persist, including small sample sizes, short intervention durations, and a lack of randomized controlled trials. Future research necessitates expanded basic and clinical investigations, particularly evidence-based scientific clinical studies. For example, multi-modal neuroimaging techniques, such as functional MRI and magnetoencephalography, could be employed to parse the spatiotemporal dynamics of visuomotor integration during calligraphic creation. Concurrently, leveraging artificial intelligence to analyze handwriting characteristics derived from calligraphy training could facilitate the development of models correlating these features with electroencephalographic (EEG) signals. Such endeavors are crucial for a deeper exploration of the mechanistic pathways by which calligraphy training impacts cognitive function in this population, ultimately offering novel approaches and methodologies for cognitive impairment intervention.
