Grandma was an independent woman who supported a family of five during the great depression by working a full time job as well as running a boarding house. In her mid 60s, she started eating lots of icecream and chocolates and drinking more alcohol. In her late 60s, she started having car accidents and getting lost. We helped her move into assisted living, but she died as a result of the stress of a motor vehicle accident soon after that. I always wondered if her love of high fat foods contributed to her relatively early dementia. Back in those days, they often just called it senility and did not give a diagnosis.
