"Dementia is not a single disease but a term that describes a collection of changes to memory, thinking, and personality that interfere with a person's ability to function," says Scott Kaiser, MD, a board-certified geriatrician and director of geriatric cognitive health at Providence Saint John's Health Center in Santa Monica, California. "This disorder can be caused by a variety of brain diseases or conditions." 

Alzheimer's disease is the most common form of dementia, affecting more than five million Americans.

Language difficulties, such as forgetting the right words for things, can be a sign of dementia. 

"People living with Alzheimer's may have trouble following or joining a conversation," says the Alzheimer's Association. "They may stop in the middle of a conversation and have no idea how to continue or they may repeat themselves. They may struggle with vocabulary, have trouble naming a familiar object or use the wrong name (e.g., calling a "watch" a "hand-clock")."

People with dementia may "use substitutions or talk around the word they cannot recall," says Thomas C. Hammond, MD, a neurologist with Baptist Health's Marcus Neuroscience Institute in Boca Raton, Florida. "These may be subtle language changes that are not readily noticed." To cope with language difficulties, a person with dementia may become withdrawn and socially isolated.

Matthew Diggity : Takes the conclusions of some research at face value without taking the implications to the next level. For example the recommendation of fish for one purpose but without sufficient consideration of other factors taking into consideration ocean pollution.
Matthew Diggity : There are a large number of diet articles around, espousing a variety of “healthy” lifestyles, and often these are unsustainable over the long term either for financial or health reasons. Many look at such factors as calories, fat, carbohydrates and more without really considering the foods themselves beyond that. This article isn’t a diet, per se; instead, it looks at the individual foods and explains how the body uses them to heal and regenerate itself.
Matthew Diggity : This article made me feel like I can actually EAT again. Doesn't give you a list of 100 foods you can't eat and doesn't feel like a fad diet (and not a diet at all). I also loved that the author gives you access to all his research - so you can look it up for yourself (probably won't, because I trust this dude). Really excited to help heal my gut with this article!
