在某一天風和日麗的下午，我的line久違的被心理學老師敲了一下
心理學老師： 這幾年有文獻顯示，看著40hz的燈光可以幫助失智病人的大腦清掉斑塊 （但這個工具可能涉及醫療服務所以需要收費）
居然有這麼神奇的事！於是我找了一下這篇研究的出處，然後找到了底下這篇論文
Light and Cognitive Therapy for Alzheimer's Disease
What Is This Study About? Electrical activity in the brain known as gamma brainwaves helps connect and process information throughout the brain. Research suggests that exposure to a light flickering at 40 Hz may promote gamma-wave brain activity, which could potentially activate cells in the brain to eliminate beta-amyloid plaques that are common in Alzheimer's disease. This one-year observational study will test the ability of an iPad application, also called an app, to improve cognition, function, and quality of life in people with Alzheimer's disease. Participants will use the iPad app on a daily basis to play cognitive games (e.g., Sudoku, Tic-Tac-Toe) while being exposed to light therapy at 40 Hz. Each month, the participant's caregiver will use the app to report on the participant's functioning in daily living activities. portal for the research
畢竟也沒什麼技術難度，體感覺得10分鐘以內可以寫完 所以我就快速寫了一個demo
step 1 list usecase
step 2 直接寫完（？
step 3 大功告成～
