Is Your ADHD Treatment Making You Worse?

If you are being treated or are going to be treated for ADHD, it is important to look at a study released last week by the journal PLOS One. For many patients, the popular ADHD medication methylphenidate (Ritalin) has been shown to have both positive and negative effects. This study shows that treatment with methylphenidate increased the amount of dopamine transporters in the brain by 24% over the course of just one year of use. Likely, this is not a good thing.

Dopamine is the brain chemical largely thought to be responsible for reward-motivated behavior, and ADHD is often associated with low dopamine activity. In your brain, synapses are the places where neurotransmitters like dopamine stimulate action. Dopamine transporters are responsible for clearing dopamine from the synapse into surrounding cells once the dopamine has “fired” its signal. The more quickly dopamine gets cleared from the synapse, the less dopamine is available to do its work. Methylphenidate gets results by blocking dopamine transporters, giving your brain more opportunity to get the benefit of the dopamine.
You don’t want excessive amounts of dopamine transporters hanging out in your brain, or whatever dopamine you do have gets cleared quickly.

This study, done by noted neuroscientists Gene-Jack Wang and the National Institutes of Drug Abuse Director Nora Volkow and others, dealt with adult sufferers of ADHD who had never before been treated with medication.

They took 18 never medicated ADHD adults and did PET scans on them before and one year later. They compared the ADHD adults to 12 normal control subjects, also scanned at baseline and then a year later. The ADHD subjects treated with the drug showed a 24% average increase in dopamine transporters, while the control subjects showed no increase in transporters.

It appears that while methylphenidate is blocking the transporters, it’s also somehow inspiring the multiplication of them. Imagine, then, what happens to the person with ADHD who wants to stop taking medication. He or she may be even more vulnerable than before taking medication.

There is a lot to learn, and clearly ADHD medications have long term benefit for many. However, it brings into sharp relief the reality that we ought to be cautious in the prescription and use of pharmaceuticals in the treatment of any condition of the brain, including ADHD.

The reality is that ADHD is for the most part being treated with too much medication and not enough case-by-case understanding.

Shortly after I began brain SPECT imaging work over thirty years ago, I realized that ADHD is not a single or simple disorder. There isn’t just one brain SPECT pattern for sufferers of ADHD. It took me several years and thousands of scans to identify at least seven unique SPECT patterns in ADHD patients, each of which ought to be treated differently.

If you had chest pain, your doctor would go through a series of diagnostics to discover the exact nature of it before prescribing you any medication or suggesting any procedure. In my experience, ADHD should be approached with the same attitude of caution, discovery, thoroughness and sensitivity. One treatment does not fit every ADHD patient!

Have you ever discontinued use of Ritalin or other stimulants for the treatment of ADHD, only to find symptoms return?

ADD is a complex medical condition that cannot be summed up by simple, blanket statements. These ADD myths attempt to oversimplify and stigmatize individuals with ADD. The truth about ADD is that given effective treatments, support, and strategies for overcoming challenges, individuals with ADD, can and do, thrive.

    When my son was in the 4th grade we put him on Quillavent for ADHD. For the first 4-5 months his school work improved. Then he started experiencing hallucinations, nightmares and facial tics. The doctor had us stop the meds immediately. I believe the meds plus the immediate withdrawal made the progression of his disease alot worse. He is now on the autism spectrum, ADD with developmental dyspraxia. We recently had a SPECT and EEG, showing severe inflammation. He is now on Lamictal, supplements, going to OT and soon to start neuro therapy. Too soon to know if this is going to be the right course of action, but I do believe we are on the right path now.

    hey there! I have a son who is adhd, anxiety, odd, He was on Ritalin and it made is behavior unbearable. Someone mentioned to me to have him checked for Temporal Lobe Epilepsy. He has told me his eyes shake sometimes, he seems to be staring into space…and sometimes i feel like he just isn’t my kid…there are other symptoms I have with him…but is this possible? Thank you for your time.

    • Hi Amy, Temporal Lobe Epilepsy is a possibility. It might be a good idea to have a phone appointment with one of our doctors. Please give us a call at 866-260-8227.

      HI, I know its been a year since you posted, but I was wondering if you got any answers to your problem? I have ADD and have these times when I stare into space, as well as anxiety and other negative behavioural traits. Just been researching the link with Temporal lobe epilepsy and ADD so that I can get the right treatment here in the UK. Just been put on Ritalin, but still having these weird long stares when Im tired and not sure if the meds are working as I seem to task jump just as much and fast as I did before.

  • P.F.

    You said that stimulants increase chemicals in the temporal lobes. Is it both methylphenidate and amphetamines that stimulate them? Or just amphetamines?

    Hi, I have a situation that bothers me. My son seems to be hyper and always on the go but he is 4. I had him evaluated and he was cleared for ADD, ADHD, and autism spectrum disorders. He listens well and is able to learn quickly. he is already able to read and is farther along in some subjects than many kindergardener at his school. He started pre-k a month after his evaluation. His preschool teacher has been bugging me regularly since then about getting him re-evaluated because she is sure he has ADHD. She compares him to a previous student she had and insists that medication would help. The psychologist that saw my son will not put a label on him and refuses to evaluate him again until the end of the year. The teacher however has pushed and pushed until his pediatrician received a questionnaire the teacher filled out that makes him fall into the ADHD category according to that piece of paper. He has now been prescribed methylin and is taking one dose a day. He’s been on it for a week and the teacher sends good reports home already even though his doctor said it would take a month to really work. I was on the fence about the meds but now I’m just very uncomfortable with it. My son was always a good listener and strived to do what was right and for a 4 year old he was pretty trustworthy, he was just always on the up and up until bedtime. Now my son acts crazy after school like I’ve never seen before. He spins around and gets into things he would never touch before. He colors on the walls, gets angry and has outbursts for no reason. He doesnt listen well anymore and generally just seems like all his regular energy has been packed into the few remaining hours of the day rather than spread out evenly and its not being channeled positively. This kind of behavior has him doing things that get him into trouble at home yet he’s “just great!” At school and I know it’s not right. If my son doesn’t actually have ADHD could this medicine be messing him up? What are the effect of a stimulant on someone without a hyperactive disorder?

    • Veevslav

      High norepinepherine and/or low gaba would be my guess. Gabaergic should be the treatment option, but I am not a doctor and thus I cannot have the brains to know this and figure it out when the standard Dr. is confused by it.

      It sounds to me like he is becoming angry/agitated as the medication wears off at the end of the day. Ritalin boosts dopamine and norepinepherine. If you love your son keep him off Vyvanse and Strattera.

  • Christian Lamon

    I’m an 18 year old guy that was prescribed 60mg/day vyvanse not for diagnosed adhd, but for treatment of anxiety with symptoms/suspicion of Adhd. I have always gotten good grades and have kicked ass at everything I do. I took vyvanse because It turned my brain into a Machine, My grades went from b to A+ and I felt like this is who I am, with more self-control. As time went on the vyvanse grew less effective til I was unconsciously aware of the fact that I was messing my brain up pretty good. Of course I thought if I was it would get better, my doctor told me this was a safer form of adderal, and I never binged on it. I figured this is what a tolerance feels like, until I stopped taking them for 6 months. (cold turkey) I now feel like a once confident respectable person, that people look at like kid. The Medication masked the stress of normality. I lived in auto-pilot for a sizable portion of those six months, and until I had concern about my brain health I was perfectly content living a life-style far from one I had invisioned for myself. Why would I be bored in school when I can write in a notebook all class period and have a blast? I graduated high school, stopped taking the medication, met ends with the girl I loved for a third of my life, moved away from everything I really cared about, and started an apprenticeship. I picked up on things faster than anyone my supervisor had trained, I should be a successful person right? I fuck everything up now. My brain has not come close to a full recovery, it’s all up and down as far as cognitive ability and energy. While a newly found passion for my work ethic has appeared its hard for me to care about much at all. It’s almost like a bipolar switch at stressful times. What the hell do I do? I’m ready to give up.
