Idebenone (trade names Catena, Raxone, Sovrima, among others) is a drug that was initially developed by Takeda Pharmaceutical Company for the treatment of Alzheimer's disease and other cognitive defects. This has been met with limited success. The Swiss company Santhera Pharmaceuticals has started to investigate it for the treatment of neuromuscular diseases. In 2010, early clinical trials for the treatment of Friedreich's ataxia and Duchenne muscular dystrophy have been completed. As of December 2013[update] the drug is not approved for these indications in North America or Europe, but it is approved for the treatment of Leber's hereditary optic neuropathy (LHON) in Europe. Chemically, idebenone is an organic compound of the quinone family. It is also promoted commercially as a synthetic analog of coenzyme Q10 (CoQ10).

1.Idebenone increases nerve growth factor (NGF) in the brain.
2.Idebenone is a powerful antioxidant and positively affects brain chemistry.
3.Idebenone has been shown to promote information transfer across the corpus callosum, the membrane separating the right and left brain hemispheres. 
4. Idebenone has been used to treat Alzheimer's and to lessen damage from strokes.
5. Idebenone can increase production of the brain neurotransmitters serotonin, dopamine, adrenalin, and noradrenanlin.
