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

"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 started working with my coach, Twila, I was looking for a coach because I was extremely frustrated by several things: my boss, lack of planning, disorganization, impatience... etc. Most of the goals I had initially (e.g. being calm, less angry, submitting expense reports, paying bills, starting to plan my day/week...) I accomplished in the first 6-9 months of coaching. Twila was excellent at helping me develop systems that worked for me.I appreciated that she was relatively available when I was having a hard issue with my boss. I developed an excellent relationship and friendship with my boss (who at the start I was saying I would never work for).Coaching has helped with the following:1. Keeps me focused on achieving my goal2. Provides supportive accountability (I had great experience at sliding by... without anyone noticing)3. Over time, Twila could help spot repeated cycles/behaviors I was not as aware of4. Ongoing encouragement... which I needed5. Helped me develop ways of "naturally" doing many of the mundane tasks I had avoided.6. My base salary has increased by 30%7. My work hours have decreased by 30%8. Return on investment (ROI) is approximately 525%9. My performance appraisal no longer says: "I should be more patient... or that I should not be frustrated by others." :-)I also enjoyed/enjoy the "coaching" time and found that just having the call would start calming/relaxing me.Twila has worked with me to allow me to keep and exploit the traits I like about ADHD (i.e. energy- some may call hyperactivity, ability to pay attention to several things at once, and handle urgent tasks) while changing the traits that frustrate me (and often others)."

Twila is a super coach -- attentive, caring, organized and skillful. I worked with Twila for several years and gained the much needed skills to handle numerous drises that I was experiencing after a divorce and in establishing myself in a career. Twila is nonjudgmental, very easy to talk to and insightful. One of the important life skills that I gained from our sessions was learning the difference between discernment and judgment and how to employ these insights in interpersonal relationships. If you are in transition and trying to figure out a new path, Twila will be a tremendous resource and personal advocate.

“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!”

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’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.
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.

"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.”
Glen H.
"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."
