Military deployment is associated with increased risk of mild cognitive impairment (MCI). Combat stress related memory deficits has been well documented. Mild cognitive impairment such as memory deficits are the most common and earliest symptoms of Alzheimer?s disease and related dementia (ADRD). The complaints about declined memory are common in healthy and cognitively intact civilian older adults, but less understood in aging combat veterans. Brain training strategies to enhance cognitive skills and especially memory processes are unmet needs in aging combat veterans who are at additional risk for MCI induced by ADRD. Since currently there is no effective drug treatment to stop cognitive decline, noninvasive brain training to boost memory functions in older veterans is an increasingly attractive option to attenuating decline in memory. The proposed project is poised to investigate state-of-art neurofeedback (NF; biofeedback of brain activity) training for self-modulation of neural plasticity to boost memory performance in veterans. The recent advance of NF with Brian-Computer Interface (BCI) has provided a novel way to examine brain functions and plasticity. Thus far, there has been limited application in developing effective experimental and clinical paradigms for rehabilitation in veterans. Historically, brainwave patterns during memory task performance have been analyzed offline, a methodology which does not allow real-time NF modulation and training. The proposed project is poised to investigate state-of-art neurofeedback (NF; biofeedback of brain activity) training for self-modulation of neural plasticity to boost memory performance in veterans. The central hypothesis guiding this research is that optimal memory-related brainwave patterns of a veteran can be trained. The online NF allows maximization of brainwave patterns associated with healthier memory states. The development of efficient NF paradigms to augment memory performance is an important first step for the application of this nonpharmacologic intervention to improve combat veterans? memory functions and potential for treating MCI due to mild TBI or pain. We will use state-of-the-art wearable wireless brain-computer interface headset, which is affordable and can be easily set up in VAMCs and eventually in remote assessment settings. This innovative, cognitive neuroscience based, nonpharmacologic intervention serves to revolutionize the diagnosis and treatment of combat veterans who are at risk for degenerative dementia.
