The Brain Exercise Initiative is a student run non-profit organization that uses math, reading and writing as a form of cognitive development for the elderly. It is found that simple math exercises and reading aloud for just 30 minutes a day can have a positive impact on memory for those with Alzheimer's. This is currently being done extensively in Japan. It was discovered by a Japanese doctor, Ryuta Kawashima, and consists of math exercises and reading aloud of short stories. Done for just 30 minutes a day, 5 times a week, improvements in Alzheimer’s patients have been observed. It is currently being done in 1,400 care homes with 15,000 Alzheimer's patients all over Japan and has had great success. Many individuals showed improvements in communication and behavior. Some went from being bedridden to sitting in a chair or walking. Some showed improvement in controlling their bowel movement. Additionally, they began to feel happier.
