Efficacy and Safety of Near Infrared Light Therapy for Alzheimer's Disease
- Conditions
- Mild to Moderate Alzheimer's Disease
- Registration Number
- NCT06008639
- Lead Sponsor
- Danyang Huichuang Medical Equipment Co., Ltd.
- Brief Summary
To explore the efficacy and safety of near infrared light therapy for Alzheimer's disease. Each subject will be numbered and their medical records will be established. The subjects will be randomly assigned to the treatment group or the control group for 30 minutes/day (5-6 days a week) for 4 months while the treatment group is active settings and the control group is sham settings.Follow-up visits will be conducted at 2 months, 4 months and 2 months after treatment. At each follow-up, scale assessment, blood, MRI, and EEG were observed

- Primary Outcome Measures
Name Time Method Change from baseline in ADAS-cog 8 weeks, 16 weeks and 24 weeks Alzheimer's Disease Assessment Scale - Cognitive section ,ADAS-Cog；The higher the score, the worse.
Change from baseline in MMSE 8 weeks, 16 weeks and 24 weeks (Mini-Mental State Examination, MMSE ;The higher the score, the better.
Change from baseline in ALFF 8 weeks, 16 weeks and 24 weeks The amplitudeof low-frequency fluctuations, ALFF;The increase of ALFF indicates that neuronal excitability and metabolism are enhanced, while the decrease of ALFF indicates that neuronal spontaneous activity is inhibited.
- Secondary Outcome Measures
Name Time Method Change from baseline in HAMD 8 weeks, 16 weeks and 24 weeks Hamilton depression scale,HAMD; The higher the score, the worse.
Change from baseline in ADCS-ADL 8 weeks, 16 weeks and 24 weeks Alzheimer's Disease Cooperative study-Activities of Daily Living Scale，ADCS-ADL;The higher the score, the better.
Change from baseline in MOCA 8 weeks, 16 weeks and 24 weeks Montreal Cognitive Assessment, MoCA；The higher the score, the better.
Change from baseline in ADCS-CGIC 8 weeks, 16 weeks and 24 weeks Alzheimer's Disease Cooperative study-clinical global impression of change scale，ADCS-CGIC
Change from baseline in NPI 8 weeks, 16 weeks and 24 weeks Neuropaychiatic Inventory，NPI；The higher the score, the worse.
Aβ amyloid and tau levels 8 weeks, 16 weeks and 24 weeks Plasma Aβ and Tau proteins are thought to be related to the pathogenesis of AD; The lower the protein level, the better.
MRI 8 weeks, 16 weeks and 24 weeks Magnet Resonance Imaging,MRI; The brain volume, hippocampus volume, links between brain regions will be observed.
