  • Treatment involves dietary changes, exercise, and lipid-lowering drugs. (msdmanuals.com)
  • Historically, an overnight fast was deemed necessary before lipid screening, but adult data suggest nonfasting lipids may be appropriate for initial screening for cardiovascular risk. (medscape.com)
  • It is now evident from improvements noted in this Huntington model, a placebo-controlled phase 1/2 disease clinical trial in Friedreich's ataxia, continuing improvement in two Expanded Access subjects with the strictly progressive, fatal disease, infantile neuroaxonal dystrophy, and dozens of specific animal and cell models of diseases, that lipid peroxidation is a validated, druggable target across many diseases of neurodegeneration," Dr Shchepinov added.
