Clinical Trial Summary

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive cognitive dysfunction and behavioral impairment. It is currently the most common type of dementia in the old age. At present, the clinical treatment of Alzheimer's disease is expensive and has side effects, so it is very important to explore new methods of treatment for AD. Investigators designed a prospective, randomized, double-blinded and placebo-controlled trial to investigate the effect of transcranial alternating current stimulation (tACS) on cognitive function in AD patients and to assess the biological effectiveness of the treatment.

Clinical Trial Description

As the population is aging, there is an urgent need to develop new methods of treatment for AD. Noninvasive neuro-regulation is a new technique in treating neuropsychiatric diseases. It include transcranial magnetic stimulation, traditional transcranial direct current stimulation, traditional transcranial alternating current stimulation and etc. Previously, conventional transcranial direct current stimulation had shown inconsistent results in the treatment for AD. This may be related to the low current density of traditional electrical stimulation in deep brain areas, such as hippocampus and amygdala, and leading to poor stimulation effect. Compared with the traditional transcranial electrical stimulation technology, the high intensity tACS greatly improves the current intensity, so that the electric field intensity to the deep brain nucleus during stimulation is greatly increased, and it avoids side effects such as burning sensation. Therefore, it could be used for AD patients. However, there are few clinical studies on high intensity tACS on AD, so investigators designed a randomized double-blinded placebo-controlled trial to explore the effect of high-current tACS on AD. At the same time, multimodal functional brain imaging before and after treatment will be used to compare the changes of brain function activation and cerebral hemodynamics in AD. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
