Mild Cognitive Impairment Community Screening and Early Intervention Via Stem Cell Therapy and Wearable Brain Computer Interface Device.

Participants engage in structured wellness programs, including cognitive training exercises (e.g., memory games, problem-solving tasks) and lifestyle counseling focused on diet, physical exercise, sleep hygiene, and stress management. Sham elements may be included for blinding consistency.

Participants use an active non-invasive brain-computer interface (BCI) device for neurofeedback training, designed to enhance cognitive function through real-time brain activity monitoring and modulation. Sham (non-functional) devices are provided to other arms for blinding.

Participants receive administration of autologous or allogeneic stem cells through intravenous or targeted delivery methods aimed at neuroregeneration. Placebo saline infusions are used in other arms to preserve blinding.

Participants receive no active treatment. To maintain blinding, they undergo placebo procedures, such as saline infusions mimicking stem cell therapy or sham (non-functional) devices simulating BCI therapy.
