"Untangling Dementia is a winner. Complex ideas are presented in a way that caregivers can apply them to their loved ones on a daily basis. It is a book I wholeheartedly recommend.”
DENNIS R. MYERS Ph.D., LCSW, Kronzer Professor in Family Studies, Baylor University

“This book will be given to every family who visits our community and be required reading for all my employees. Tam does a marvelous job walking the reader through dementia – from diagnosis to death – in a caring, loving way.”
CARLA COCHRAN, RN, Owner,Clonial Gardens Memory Care Communities of Texas —

“Tam has a true gift when it comes to helping others understand Alzheimer’s and dementia. The information she provides in this book is invaluable for anyone who provides care for a loved one.”
MARY NORRIS, Family Caregiver, Alexandria, Virginia

"Untangling Dementia" is absolutely the most enlightening thing I have read since facing Frontaltemporal Dementia. It has answered so many questions you would not believe. My whole attitude has changed as a result of this book and the beautifully laid out stages of dementia. This woman knows her stuff!"
G.L. Hamnet

"This book is the best! I am mailing them out to family members along with your chart so my husband's children and siblings can read it and understand where he is. Your book and chart made me realize that he is much further along than I thought - he just still has good social skills and compensates well. Thank you for your wonderful work!"
B. A. Hanson

"Thank you so much! I have ordered five copies for my family and the caregiver. I'll have a copy for those who care for my husband so they might better understand the disease. Very few Home Care Agencies educate the caregivers so I find it's my "job" to try to do that and having your book is a great help."
A. Tholsen

"Just wanted to let you know that we gave your book to a new resident's family. Two of the children were "on the same page," but unfortunately the son was not. At our support group this week the daughter told me that her brother had read your book and called her on the phone to tell her that he had an epiphany after reading your newest book and he now "gets it," as they say... Thank GOODNESS, and THANKS, TAM!!!"
N. Thurenco

"This book presents the reader with a very honest and candid look at Alzheimer's Disease and its progression. Ms. Cummings' experience has obviously allowed her to develop a "compassionate directness" that is hard to come by. While one must understand what to expect in a loved one as he or she progresses through the stages of the disease process, Ms. Cummings also presents the reader with valuable insight into what all people involved may experience as well. And she does so with the voice of a teacher, of wisdom of a trained Gerontologist, and the heart of an experienced care-giver. Thanks for writing this book. The language you use and the stories you tell fill a much-needed niche in the Alzheimer's literature."
Dr. Melody Madlem

"I have been dealing with my mother's rapidly advancing dementia for a couple of years and was given this book by the memory care facility where she now lives. I wish I had this book a couple of years ago. It provides a VERY helpful road map for the different stages of dementia. I was going along fairly blindly from one stage to the next, wondering what was happening. Once I read the book I realized she had been progressing through the stages described in the book. I now feel better prepared to cope with the next stages. While it is not easy to read about what is to come, at least I can prepare myself and better help my mother. If you have a family member or friend suffering from dementia this is a must read book!"
Rick Mayo

"This book is fabulous! It is such a great guide for anyone struggling with dementia, whether it is in their family or if they are working in an industry where they care for people with this disease. I am a marketing director for a memory care community, and I find that so many families I encounter have such a hard time understanding dementia. They are usually stressed out and overwhelmed from caring for their family member who is suffering with this terrible disease. There is not enough time in my office to give them all the help and education that I would like to, so I have started using Tam's book as a resource. This book has been a blessing! I ordered my first box and have been giving them out to every family that comes into my office. I have had the most wonderful feedback from everyone! Thanks Tam for sharing your knowledge and experience! It is immeasurable to all of us!"
Blitz' Mom

"My husband suffers from Alzheimer's. I have purchased this book for our children, grandchildren, and caregivers. It is an essential read if you are dealing with this cruel disease. It is easy to read and the Points to Remember at the close of each chapter really help. The book includes information about other forms of dementia too. You may think you understand Alzheimer's and other dementias, but I am certain you will learn more about the diseases, how to cope with them, and how to specifically care for those with the diseases by reading this book. The author will tell you that if the reading becomes too difficult - put the book down & return to it later. She understands how emotional reading such truths can be. I highly recommend this book."

"One of the wonderful things about this book is Cummings’s gifted way of using true-to-life examples that illustrate her points and make them easier to understand. Her explanations are matter-of-fact, but they are not without compassion for the experience. Her book contains nuggets of wisdom that every family who has someone with dementia should hear. If you are someone or know someone who has received a diagnosis of dementia and would like a great read that will give you some understanding, support, and implementable takeaways in facing your new journey, Untangling Dementia is a wonderful place to start. Thank you, Tam, for this great resource. "

"Hello Tam, I’m M.L., from Corpus Christi. I attended this year, for the first time, the Face to Face Caregivers Workshop. My intention was to go and listen to your presentation and I’m glad I did. You were fantastic! While listening to you, I kept on thinking of so many friends that should have been there to listen to what you had to say. So, thank you for your presentation!!"

"Now, about your book… oh my gosh, it’s a must have book for any Caregiver! I only bought two books, I could have bought a couple more, to give to friends. I will visit your website and buy them. The book is so well written. I found your book easy to read, very real… (really, thanks for not hiding anything from us J!) and practical. This book is now my “security blanket” always close by, to help me with any down moments I may be having."
