The researchers namely found that the body’s ability to repair the DNA in the neurons diminishes with ageing. The DNA repair mechanism seems to play a central role in the way that our neurons are damaged when we get older. When this happens, our body tries to repair the DNA through a process called DNA repair. However, harmful substances continuously attack the DNA in the neurons and damage them. Like nearly all cells in our body, the neurons contain DNA, which is the genetic information that we inherit from our parents.

The ability to repair DNA damage in the neurons diminishes with age We can start to think about ways to prevent this from happening in the first place, Sengupta states. – Our study is important because it shows that age-related loss of these neurons is not something that we have to accept as an inevitable side effect of ageing. Researcher Tanima Sengupta and her colleagues have recently made a discovery that may explain why these neurons degenerate and die when we get older. However, until today, scientists did not know why these neurons are lost. When symptoms of Parkinson’s disease arrive, most of the dopamine-producing neurons have already died. Researcher Tanima Sengupta and her colleagues found out that neurons are damaged when the neurons’ DNA is not repaired well enough. Dopamine is the neurotransmitter helping the neurons to send the messages. Neurons are therefore crucial for everything we do, from thinking to talking, feeling and moving our bodies. Neurons are a type of nerve cells that transmit information between different areas of the brain, and between the brain and the rest of the nervous system. The disease is caused by a gradual loss of neurons that produce dopamine in the brain. More than 10 million people are living with the condition worldwide. The most common symptoms of Parkinson’s disease are muscle rigidity, tremor, slowness of movement and poor balance.

Parkinson’s disease is a progressive neurological disorder that affects the body’s ability to move.
