AD/HD is not a new diagnosis as some believe. It has been around for over a century, but it has been called different things like "minimal brain dysfunction", "hyperkinetic impulsive disorder," and "attention deficit disorder (ADD)." Currently the official recognized term since 1994 is Attention Deficit/Hyperactivity Disorder (AD/HD). However this term did not begin to be used more frequently until 2005. There are still many, including professionals, who use the terms ADD, ADHD and AD/HD interchangeably.  Now there is a trend to use ADD for the type that is inattentive and ADHD for the type that is hyperactive.

According to the DSM IV (the manual used by those diagnosing individuals with AD/HD) there are three different types of AD/HD:

  1. Predominantly Inattentive Type (some people refer to this as ADD)
  2. Predominantly Hyperactive/Impulsive Type (some refer to this as ADHD)
  3. Combined Type

It is estimated that the prevalence of AD/HD is:

  • 5% - 7.5% in children
  • 3-6% in adults

Once thought to be a childhood disorder predominately affecting males, we now know that approximately 75-85% of children will continue experiencing this condition on into adulthood and that it also affects females.

AD/HD has different causes and there are differing theories that have been studied, such as:

  • Genetics
  • Neurobiological challenges in several different areas of the brain, including the pre-frontal cortex
  • Developmental disorder of self-control (Barkley 1995)
  • Brain Insults – head trauma, toxins/chemicals
  • AD/HD is NOT caused by sugar intake or poor parenting. Learn more about causes

There are several myths about AD/HD that are being dispelled. Learn more about myths...
Treatments for AD/HD typically involve a multi-modal approach. Learn more about treatment...

Some people with AD/HD are successful to a certain point and others suffer devastating failures.

ADHD Coaching: What Our Clients Are Saying

"Before I worked with Twila I was feeling like life was pretty chaotic. I didn't seem to have a grip on things and I felt like my communication skills were poor. "I wasn't doing a good job of letting co-workers and my partner know what I needed from them. I seemed to be working under a general state of overwhelm. I have worked with Twila for a couple years. For me this has been time and money WELL SPENT. I am much more organized, thoughts and life. Before I couldn't see past the chaos but now I seem to be able to step back from things and see the real issues. I have been able to identify key areas needing attention in my life. I have made a lot of healthy improvements. This was something I didn't seem to be able to do on my own. I have improved my communication skills, personal and professional, and relationships are better. My partner said he has seen a great change in me all for the better. He has seen me grow and better myself and this has encouraged him to do some of his own work. Twila seems genuinely interested in my success as a person."
Kelly J., Washington

"What have I accomplished through coaching? A better question is what haven't I accomplished through coaching! To state it briefly, I have accomplished a Ph.D., salary raises of $60,000 over 6 years, 4 promotions, respected positions in Fortune 500 companies, and my own business. I have also accomplished a home-life balance, a positive focus on more structure in my parenting, and a greater sense of peace and direction in both my personal and professional lives. "Thank You" does not say it. "Bless you" comes closer."
Jeane F., PhD., Manager of Organizational Effectiveness
“Coaching has been a true life changer & saver for me. Most likely the results are going to be different for everyone, as dictated by different situations. For me, this has not only helped my career and college goals become enjoyable and achievable, but it has almost essentially helped me to combine all of the important things in my life much more efficiently, so that I have been able to pretty much save the severe degradation of my marriage. ADD/ADHD has, without knowing that it even existed, been an absolute key product of absolute upheaval and chaos in my life. Since I’ve been getting help from Twila, I’m truly realizing what I’ve been missing most all of my life. Needless to say, I would highly encourage you to consider life coaching if it has been recommended, or you think it might possibly be helpful for you. So far so good for me.”

If you have come to a point in your life where you deeply desire to make adjustments in your thinking, habits, processes and/or performance, but feel stuck, Twila can provide tools, training, coaching and accountability necessary to get going and to achieve long term change.

ADD can be an overwhelming condition that affects every facet of life….from personal relationships and careers to the mundane. Over the years I’ve worked very hard to educate myself on my condition, believing that through sheer will and determination I could navigate life’s extra ADD challenges. This proved to be a stressful exercise while only producing mixed results. So with my life in disarray it was my great fortune to find Twila Gates. You will not meet a more understanding and compassionate individual with the talent, know-how and desire to see you succeed. Partnering with her produced measureable gains with every goal we set out to achieve. She helped me lift the burden of frustration which had accumulated over a lifetime with strategies tailored to my specific needs. I will always appreciate that she helped me develop the tools to overcome those challenges as well as embrace the positive aspects of ADD as a gift. Twila is an absolute gem and you will count yourself among the fortunate if you have the opportunity to work with her.

"I have always felt like I take two steps forward and four back. Having a coach helps me to keep the steps I take and more. The last two years has been life changing financially, physically and mentally. I look forward to my calls. I can never thank Twila enough for her support and encouragement."
Lori S., Arizona
“My new house is coming along well. It should be ready by spring... When I move into the new home, my life has progressed in a way that will fit the new home, sort of like a snail growing and needing a new shell... Yes, I now have a full and well-rounded social life!”
Patricia T., Florida
“I’m doing really well. My business continues to flourish. One of my goals when I came to you was to make $90,000... Well, this year I made $113,000. I find that amazing. And I owe so much of my success to you, Twila. I have enough work lined up for next year to make that much again, but work 240 hours less! Now that’s even more amazing!
Kelly C.
"This note comes to say how much I appreciated your support and wisdom as my coach. You were an awesome aspect of my life. I'm not sure what this year has coming ... but whatever it is I am excited and looking forward to "it" ! All in all, I'm looking for good things to happen this year and I still recognize this past year as my "MIRACLE" Year because God provided immensely but most of all with help from him and others like you, Twila – I survived !!! "
Janice M.
"When I first contacted Twila the "overwhelm" factor in my life was so debilitating that I was unable to perform functions as basic as paying my bills on time. I didn't have a job and had no money coming in. I had just decided to close the business I had been running, or stated more correctly, had been running me for almost five years. This was the fifth career in which I achieved "failure" status. My wife was feeling very insecure, which had a major effect, of course, on our family. At age 46 and just weeks away from turning 47, I was very dejected, to say the least, and sinking fast. That's when I realized I had all the symptoms of ADD, and found coaching.Twila helped me gather my thoughts, decide on the best career course to follow and smooth out relations with my wife and children. She helped me do all this within the span of a few months. I secured a job in which I was able to employ my strengths and achieve harmony and satisfaction for the first time in my life. Within less than two years, my salary has increased more than 50%, I am valued and respected at work, my wife feels much more secure and I am back on track with my family. I have a system for keeping my overwhelm factor in check and am improving my efficiency through use of tools for ADHD. Thank you for helping me find my life."
