简要总结
This study will gather data to see if infrared and near infrared light frequency can increase the activity of brain cells and provide support for the cell's ability to repair and protect themselves against further damage.
详细描述
Research suggests that impaired regional cerebral blood flow (rCBF) [flow of blood in certain parts of the brain] plays an important role in dementia. Infrared and near infrared light frequency has been shown to increase the activity of brain cells and provide support for the cell's ability to repair and protect themselves against further damage. This study will evaluate the effects of repeated brief exposure to near infrared light stimulation twice a day on subjects that have problems such as attention span, working memory, strategies of learning and remembering, planning, organizing, self-monitoring, inhibition and flexible thinking for an 8 week period.

研究组 & 干预措施
Helmet Active Device
Patients will be randomized 2:1 ratio to receive either the helmet active device or the helmet sham matched device. EACH device will be delivered with a highly visible tag with either an 'A' or 'B' respective to the study group the patient was randomized to.

结局指标
主要结局
Memory Score
时间窗: Before first treatment, at 4 weeks and then at 8 weeks.
Mini Mental State Exam will be performed in beginning of the study (before first treatment), in the middle of the treatment (in 4 weeks) and in the end of treatment (in the end of 8 weeks). This quick assessment will be able to score assessed individuals using 0-30 scoring range. Collected scores will be compared at different time points and any numerical change in score will be evaluated.
Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog test) test
时间窗: Before first treatment, at 4 weeks and then at 8 weeks.
ADAS-Cog test will be performed in beginning of the study (before first treatment), in the middle of the treatment (in 4 weeks) and in the end of treatment (in the end of 8 weeks) to measure cognition. This comprehensive test will measure patient's ability of language and memory. Test consist of 11 parts and will help to assess baseline and determine cognitive change over period of treatment using patient's ability to answer questions and given score.
Quantitative Electro Encephalography (QEEG)
时间窗: Before first treatment, at 4 weeks and then at 8 weeks.
QEEG measurement will be performed in beginning of the study (before first treatment), in the middle of the treatment (in 4 weeks) and in the end of treatment (in the end of 8 weeks). This measurement will use modern analytic software to process activity of the brain during cognitive task in the forms of electrical signals received from the surface of the scalp. Analytical software uses algorithms to assess recorded brain impulses and evaluate brain function, helping to track changes in the brain function due to treatment. Waveforms of EEG being assessed: 1. Delta frequencies (1-4 HZ) are produced during sleep are widespread in the frontal central region. Delta is necessary for sleep and stillness. 2. Theta frequencies (4-8 HZ) are associated with selective attention, retrieving newly learned information, and preceding sleep. Theta aids creativity and problem solving. 3. Alpha frequencies (8-12 HZ) appear in the posterior when the eyes are closed. It is associated with idling and
