Mendi is not a medical treatment and is not intended to diagnose, treat, cure, or prevent any diseases. However, Mendi can help to strengthen the neural networks of focus and mood that exist in your brain but haven’t been attended to. If your doctor suggests medication that increases the concentration of certain neurotransmitters or chemicals in your brain that she/he deems to be lacking, Mendi can then help to direct them. But it cannot increase or decrease them on its own.
There are significant scientific studies suggesting a positive role of neurofeedback in both ADHD and depression. You can think of Mendi as a tool to access the physicality of your ailment. Kind of like if you sprain your ankle, your healing protocol requires physical feedback as well as physical therapy. Mendi provides the physical feedback for your brain, your doctor provides the necessary physical therapy.
