A sample of brain tissue from a person with Parkinson’s disease, showing clumps of protein known as Lewy bodies High levels of a certain enzyme in the fluid around a person’s brain and spinal cord could be a sign that they have Parkinson’s disease – potentially enabling the condition to be diagnosed earlier.
Hansson and his colleagues carried out tests on 81 people with Parkinson’s disease or DLB and 347 people who had no symptoms of the conditions. They collected each person’s cerebrospinal fluid, which bathes the brain and spinal cord, by inserting a needle into the spinal canal.

– Mysterious RNA Circles Produced by Cells Damaged in Parkinson’s and Alzheimer’s DiseaseResearchers are gaining new insights into neurological diseases by studying circular RNAs (circRNAs) in brain cells. Investigators found and cataloged mysterious RNA circles that are linked to brain cell identity Findings show that circular RNA is produced by brain cells damaged in Parkinson

Newly discovered trigger of Parkinson's upends common beliefsA new study challenges a common belief in what triggers Parkinson's disease. Degeneration of dopaminergic neurons is widely accepted as the first event that leads to Parkinson's. But the new study suggests that a dysfunction in the neuron's synapses leads to deficits in dopamine and precedes the neurodegeneration. The findings open a new avenue for therapies in which drugs target neuron synapses before neurons degenerate.
