The research was carried out by Dr. Lester Mitscher at the University of Kansas. Antioxidants help prevent the development of certain diseases, especially cancers. If free radicals are left alone they can cause damage to cellular DNA, and trigger disease. A new generation of drugs has been developed that treats depression by increasing your motivation. Depression is thought to arise from abnormal levels of nonadrenaline and serotonin in the brain.
Serotonin regulates mood, while nonadrenaline regulates energy, motivation, and drive.
Depressed people have both these substances in very low levels. In the past, sufferers have largely relied on antidepressants, such as Prozac, which alter serotonin levels to elevate their mood. However, a new drug, called reboxetine, works uniquely on the brain's nonadrenaline levels to improve motivation and drive. Until now these symptoms of depression have been largely neglected.
