CoQ10 supplementation has been widely used for mitochondrial disorders. The rationale for using CoQ10 is very powerful when this compound is primary decreased because of defective synthesis. Primary CoQ10 deficiency is a treatable condition, so heightened \u201cclinical awareness\u201d about this diagnosis is essential. CoQ10 and its analogue, idebenone, have also been widely used in the treatment of other neurodegenerative disorders. These compounds could potentially play a therapeutic role in Parkinson\u2019s disease, Huntington\u2019s disease, amyotrophic lateral sclerosis, Friedreich\u2019s ataxia, and other conditions which have been linked to mitochondrial dysfunction. This article reviews the physiological roles of CoQ10, as well as the rationale and the role in clinical practice of CoQ10 supplementation in different neurological diseases, from primary CoQ10 deficiency to neurodegenerative disorders.<\/jats:p>","DOI":"10.3390\/ph203134","type":"journal-article","created":{"date-parts":[[2009,12,2]],"date-time":"2009-12-02T03:06:01Z","timestamp":1259723161000},"page":"134-149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Coenzyme Q10 and Neurological Diseases"],"prefix":"10.3390","volume":"2","author":[{"given":"Michelangelo","family":"Mancuso","sequence":"first","affiliation":[{"name":"Department of Neuroscience, Neurological Clinic, University of Pisa, Tuscany, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniele","family":"Orsucci","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Neurological Clinic, University of Pisa, Tuscany, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria","family":"Calsolaro","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Neurological Clinic, University of Pisa, Tuscany, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Choub","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Neurological Clinic, University of Pisa, Tuscany, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriele","family":"Siciliano","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Neurological Clinic, University of Pisa, Tuscany, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2009,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1016\/S0891-5849(00)00307-5","article-title":"Regulation of ubiquinone metabolism","volume":"29","author":"Dallner","year":"2000","journal-title":"Free Radic Biol.
