Final answer:
Alpha lipoic acid, carnitine, and substances like Erythropoietin (EPO) and human growth hormone (hGH) can be used to increase mitochondrial function as a treatment for HD.
Step-by-step explanation:
When it comes to increasing mitochondrial function in the treatment of HD, there are several options available. One option is to use α-lipoic acid (ALA), which has been shown to improve memory performance and delay mitochondrial decay in diseases like Alzheimer's and Parkinson's. Another option is the use of carnitine and lipoic acid, which has also been found to enhance mitochondrial function. Additionally, substances like erythropoietin (EPO) and human growth hormone (hGH) can be used by endurance athletes to improve aerobic respiration and muscle recovery.
