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. 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. There isn’t just one brain SPECT pattern for sufferers of ADHD. Shortly after I began brain SPECT imaging work over thirty years ago, I realized that ADHD is not a single or simple disorder. The reality is that ADHD is for the most part being treated with too much medication and not enough case-by-case understanding. 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. There is a lot to learn, and clearly ADHD medications have long term benefit for many.
He or she may be even more vulnerable than before taking medication. Imagine, then, what happens to the person with ADHD who wants to stop taking medication. It appears that while methylphenidate is blocking the transporters, it’s also somehow inspiring the multiplication of them. The ADHD subjects treated with the drug showed a 24% average increase in dopamine transporters, while the control subjects showed no increase in transporters. They compared the ADHD adults to 12 normal control subjects, also scanned at baseline and then a year later. They took 18 never medicated ADHD adults and did PET scans on them before and one year later. 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. You don’t want excessive amounts of dopamine transporters hanging out in your brain, or whatever dopamine you do have gets cleared quickly. Methylphenidate gets results by blocking dopamine transporters, giving your brain more opportunity to get the benefit of the dopamine. The more quickly dopamine gets cleared from the synapse, the less dopamine is available to do its work. Dopamine transporters are responsible for clearing dopamine from the synapse into surrounding cells once the dopamine has “fired” its signal. In your brain, synapses are the places where neurotransmitters like dopamine stimulate action. How Can Ritalin Make ADHD Worse?ĭopamine is the brain chemical largely thought to be responsible for reward-motivated behavior, and ADHD is often associated with low dopamine activity. 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. For many patients, the popular ADHD medication methylphenidate (Ritalin) has been shown to have both positive and negative effects.
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. Hormone Evaluation and Replacement Therapy.
