NAC - N-Acetyl Cysteine Donate Fundraise NAC (N-Acetyl Cysteine) is a readily available health supplementIn its clinical strength it is used to treat paracetamol overdose and to loosen thick mucous in conditions like Cystic FibrosisNAC works by increasing the levels of an amino acid called cysteine available to the brain, which in turn increases the amount of a major antioxidant called glutathione - this, it is believed, helps to reduce neuronal death Past research has shown that people with Parkinson's have reduced levels of glutathione - we hypothesise that by using NAC to increase levels of glutathione in the brain, we can reduce neuronal death and slow down the progression of Parkinson'sThis work has been championed throughout by Professor Caroline Tanner and originally a trial was planned to take place across multiple centres in California, US. However, fundraising has proved challenging and the benefits including financially of conducting a trial in the UK under Prof Tanner’s supervision are evident and this strategy is being pursued by CPT.FUNDING IS STILL NEEDED FOR THIS TRIAL
