Enzymes for Autism and other
Neurological Conditions: A Practical Guide

Karen L. DeFelice

Amazon.com reviews

Fascinating journey and learning experience in one book, January 13, 2003
Reviewer: A reader from USA
This book was written with an intelligence, wit, and clarity that is very rare for such a technical subject. Don't be fooled by the title. The book covers autism, PDD, ADHD, Sensory integration disorder, irritable bowel syndrome, and many other neurological and gastrointestinal conditions. The author teaches rather than preaches on the science, experiences, and the how-to of using long overlooked digestive enzymes to help with many related health conditions. I went away with the knowledge I needed to understand the options and make my own informed decisions. Read it before you start any biomedical or behaviorial program. And if you have already started a program, read it so you can finally understand what is really going on, and how it can be improved with enzymes.

Excellent for professionals; very practical, realistic, January 6, 2003
Reviewer: Linda Nichols, School Principal from Missouri, USA
As an educator and grandparent of a child with an Asperger diagnosis, I found Karen DeFelice's book to be invaluable in helping to understand how enzymes work and why they are so successful for many children. Her straightforward manner of explaining a complicated subject was refreshing. In addition, her reflections on the challenges an adult with an Asperger
diagnosis faces, provided valuable insight into the challenges ahead. Those of us who have experienced the positive changes in a family member as a result of the Nutraceutical enzymes are grateful for her contribution.

Very easy to understand, January 2, 2003
Reviewer: Patricia from PA ,United States
I found the information in this book very easy to understand. It put the pieces of the puzzle together that were missing for me so I could finally understand the whole picture of why food affects my child. I could clearly make a mental picture of the digestive system in my mind and how it works by the way it was described in this book, and that helped me a lot. I have purchased extra copies of this book to give to family members and friends so they too can understand how this is all affecting my child.

Great book, easy to understand and very helpful, January 1, 2003
Reviewer: Julie from Green Bay, wi United States
I wish there would of been a book out like this 5 years ago, Karen DeFelices book Enzymes for Autism and other Neurological Conditions is great and I have found so much valuable information.Having a child with Autism I understood her struggle and need to find anything to help her children. The book is so well written and I am so grateful that she was able to write about her struggle and her findings and put them into a book that everyone can understand..I am able to now go to my daughters doctor and go over different approaches I feel will benefit her..Thanks Karen for the wonderful gift you gave to many..

Very Worthwhile, December 28, 2002

This book covers a range of applications of enzyme therapy, which is not a topic I was in a rush to read about in the past, but this book was excellent. The use of enzymes for autism is described in great detail, with many examples from real-life families. I was pleased to find the book made the subject interesting and easy to understand, even with all that research included.

As a parent, I especially enjoyed reading about the families that participated in the creation of this book and how their lives were changed through using certain enzymes. I would recommend this book for anyone investigating ways to help with neurological conditions, including autism.

enzymes really work!, December 28, 2002
andrew levin from tasmania australia
i have been using enzymes for over a year now and they give sustainable, greatly improved neural functioning and solve a lot of digestive issues. a portion of the enzymes taken also get in
the blood where they have important functions as well, promoting
healing, general well being and also having pronounced anti-cancer activity.... indeed enzyme shortfalls with aging are a major factor in cancer since enzymes encourage cell turnover and help break up potentially tumourous clusters.

autism, aspergers syndrome, add, spd are in reality conditions of neural starvation(except perhaps for brain viral infection....) and you cannot remedy this in any way except by improving the nutrient uptake to the brain and this i think is what the book is about.

a sunbeam is a world made cretinous by medical worship. parents
with children on autistic spectrum will greatly benefit by the information in this book and also themselves.....
drugs use by and large has long term toxicity issues that outweigh any short term benefit...enzymes and supplements are metabolically safe and give promise and hope for sustained future functioning.

Totally WOW book., December 8, 2002
Reviewer: A
reader from in USA
This is a unique book alright in that it brings a lot of aspects of the biology and gut issues together in an easy to understand way. It is totally WOW. It is something I think everyone who has any type of neurological issue or gastrointestinal problem should read, even if you are not interested in enzymes. If you are interested in enzymes, it gives very practical guidelines on what enzymes are, how they work, and how to start them. Since enzymes occur in all foods and in your body anyway all the time, this book is very helpful in understanding how enzymes function in digestion and overall health. Like many people, I just couldn't put it down. It was so captivating and appealing.

It was much more helpful than all the other 'technical' books I've read. Even the research was presented in an interesting way. I finally understood how it all worked together. It makes sense now. I had no idea so much was known about enzyme therapy and how extensively enzymes are used.

And it was even humorous. The author seemed to spell out what a lot of us are thinking and feeling inside. I especially appreciated that different situations were given and how enzymes were used by different families, instead of the rigid one size fits all you see with a lot of therapies. It's wonderful: one book and one alternative that is geared to making our life easier without a huge expense. Definitely worth reading.

Is There an Alternative to Gluten Free/Casein Free?, December 5, 2002
Liane Gentry Skye from Myrtle Beach, SC USA
Karen DeFelice's "Enzymes for Autism and Other Neurological Conditions" presents a heartwarming story of the marked cognitive, social and sensory improvements of her son's with Autism Spectrum Disorders after the introduction of dietary enzymes to their supplement programs. As an added bonus, Ms. Defelice employs her background as a scientist to share the vast research, solid science and biomedical good sense of utilizing enzymes as either:

-A replacement for the Gluten Free/Casein Free Diet for individuals wihtout celiac disease.
-A valuable tool to have on hand for the inevitable infractions on the GF/CF diet
-A second chance option for children who have tried the Gluten free/casien free option, but have had little to no success. This is where my children fit in.

Ms. Defelice's concise "to the point" writing style makes absorbing the scientific principals and vast research behind dietary enzymes "user friendly" for the layperson.

As the parent of two boys with Autism Spectrum Disorders, I came into enzyme therapy with great skepticism. Time proved my suspicions wrong. Moving into dietary enzyme therapy finally gave them much needed relief from harrowing, painful GI symptoms, head pain and sensory issues when nothing else could.

The cognitive gains I've seen in my children and their abilities to benefit from educational therapies after beginning dietary enzymes several months ago have been nothing short of incredible.

As a parent, the peace of mind that has come with knowing that my children are no longer in pain has been the answer to a million and one prayers.

This is a book that every family who cares about an individual with autism should take a look at. There is life--and hope-- beyond GF/CF, even for children who are well beyond their early childhoods.

This book is well-written. Topic sounds dry, but writing is enjoyable and easy to understand. I couldn't put it down. If you know someone with a neurological disorder get this for them.
