Parkinson’s drugs may lead to compulsive behavior

Parkinson’s drugs may lead to compulsive behavior

New research reveals that almost half of people with Parkinson’s disease who take dopamine agonists for their condition go on to develop impulse control disorders. Gambling addiction may be a side effect of Parkinson’s drugs, suggests new research. Parkinson’s disease is characterized by a deficiency of a key brain chemical called dopamine. Dopamine plays a […]

Parkinson’s: Could this ‘missing link’ be a cause?

Parkinson’s: Could this ‘missing link’ be a cause?

Scientists have now identified a faulty cell process that may be common to different forms of Parkinson’s, and they propose a mechanism through which it might lead to the disease. Researchers shed new light on the potential cause of Parkinson’s. This process involves a group of lipids or fatty molecules called ceramides, which are found […]

Is Parkinson’s linked to bacteriophages?

Is Parkinson’s linked to bacteriophages?

A recent study concludes that bacteriophages — or viruses that attack bacteria — may play a pivotal role in the development of Parkinson’s disease. These findings provide an intriguing new approach to the condition. Bacteriophages (depicted here) may provide an insight into Parkinson’s disease. Bacteriophages, often abbreviated to phages, are considered to be the most […]

Immunosuppressants may reduce Parkinson’s risk

Immunosuppressants may reduce Parkinson’s risk

A new study links the use of immunosuppressants — drugs that “dampen down” the immune system — with a reduced risk of Parkinson’s disease. Although the findings are preliminary, they may eventually lead to new treatments. Reducing the immune system’s activity might be a way to slow Parkinson’s progression. The authors of the study, from […]

Parkinson’s: ‘Adaptive’ brain implant may improve therapy

Parkinson’s, a neurodegenerative condition, is characterized by symptoms such as muscle stiffness and tremor in the limbs, as well as impaired balance, all of which tend to worsen over time. Has innovative research found a more reliable tool that helps to improve these symptoms? An adjustable new brain stimulation implant could bring Parkinson’s therapy to […]

Why pesticides may cause Parkinson’s in some people

Why pesticides may cause Parkinson’s in some people

New research reveals how the pesticides paraquat and maneb alter gene expression and may lead to Parkinson’s disease in people who are genetically predisposed to the illness. Some people working in agriculture are at a higher risk of developing Parkinson’s disease due to their contact with pesticides. Estimates show that around 50,000 people in the […]

Parkinson’s, dementia: Is this the key to preventive therapy?

Parkinson’s, dementia: Is this the key to preventive therapy?

Parkinson’s disease and dementia with Lewy bodies are both characterized by impaired brain function tied to neural death. A landmark new study has identified how a main culprit behind neuron damage — the alpha-synuclein protein — harms the neurons. A new ‘groundbreaking study’ may help us to understand what drives neural damage in Parkinson’s disease […]
