A number of nervous system diseases (NSD), such as nerve trauma and neurodegenerative diseases, are a major cause of disability and mortality.[157] It has been reported that electrical stimulation upregulates brain‐derived neurotrophic factor (BDNF) and its high‐affinity receptor tropomyosin receptor kinase B (TrkB) in neuronal cells. Here, BDNF is linked to neurodegenerative disease.
