Kieran Breen: The race against time to unlock this terrible illness
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.The area of the brain Parkinson's researchers are most interested in is the substantia nigra, where nerve cells die in the disease. The substantia nigra of a Parkinson's-affected brain contains cells which are alive, cells which are dying, and remains of cells which are dead.
There are specific pathological changes characteristic of Parkinson's. Changes in the levels of specific proteins or even the appearance of new proteins may provide us with valuable insights into what is happening when the nerve cells die.
The brain rapidly deteriorates after death, so it should arrive in the bank within 24 hours. The longer it takes, the more chance of cells being damaged. Because of this, we may miss subtle changes that occur in Parkinson's that may have particular importance.
Some changes during the progression of Parkinson's are likely to be associated with general ageing, so we need to compare a Parkinson's brain with a control brain. Changes specific to Parkinson's can then be identified. We will then be closer to identifying factors that may halt, reverse or prevent nerve cell death.
