Do people with Parkinson’s disease smell different?

Using the skills of a “super smeller,” researchers have identified how Parkinson’s disease alters the way a person smells. They hope that the discovery will help aid early diagnosis. A recent study investigated the links between odor and Parkinson’s. Parkinson’s is a progressive neurodegenerative condition. The National Institutes of Health (NIH) estimate that around half […]

Manganese and Parkinson’s: Mechanism may explain link

New research, published in the journal Science Signaling, details the mechanism through which exposure to manganese can trigger protein misfolding in the brain — which may, in turn, lead to Parkinson’s-like symptoms. The findings may enable an earlier diagnosis of the neurological condition. New research helps explain how and why manganese exposure could lead to […]

Parkinson’s: Study reveals how cancer drug reduces toxic protein in brain

Laboratory and animal studies have suggested that the leukemia drug nilotinib could alleviate symptoms of Parkinson’s disease. Now, using early results from a clinical trial in humans, scientists have worked out how the drug reduces toxic protein and raises dopamine levels in the brain. New research explains how a cancer drug increases levels of the […]

This sleep disorder puts people at ‘very high risk’ of Parkinson’s

Research has linked a particular sleep disorder called rapid eye movement (REM) sleep behavior disorder with a diagnosis of Parkinson’s disease. What characterizes this sleep problem, and can its presence be a good way to predict Parkinson’s risk? People who experience a sleep disorder that causes them to act out their dreams have a high […]

How does exercise impact cognitive function in Parkinson’s?

Experts have already concluded that exercise can help people with Parkinson’s disease improve their motor symptoms, but what is its effect on the cognitive symptoms of this condition? Besides boosting motor function, exercise could improve memory in people with Parkinson’s disease. Parkinson’s disease is a neurological condition that usually stands out for the motor symptoms […]

New treatment under trial could restore brain cells in Parkinson’s

A series of clinical trials have tested an experimental treatment for Parkinson’s disease that uses a novel approach: administering the drug straight into the brain via implanted ports. The leading researchers believe this may be a “breakthrough” therapeutic strategy for neurological conditions. Newly trialed therapy could launch a fresh chapter in the treatment of Parkinson’s […]

Parkinson’s: How stem cells can help repair the brain

New research examines the potential of stem cell therapy in the replacement of damaged neurons in Parkinson’s disease. The authors say that stem cells could “provide superior treatment, possibly using different types of cells to treat different symptoms” of Parkinson’s. Could stem cell therapy one day help treat Parkinson’s disease? Parkinson’s disease affects around half […]

Are we facing a Parkinson’s pandemic?

According to one new study paper, evidence is emerging that Parkinson’s disease is becoming a pandemic. The authors discuss their concerns and the challenges ahead. Parkinson’s is on the rise, but can we slow its march? Parkinson’s disease is a neurodegenerative condition. Primarily affecting the motor regions of the central nervous system, symptoms tend to […]

13 early signs of Parkinson’s disease

The hallmark symptoms of Parkinson’s disease are tremors and slow, rigid movements. Small changes in a person’s movements and behavior can signal the onset of Parkinson’s disease before diagnosis. Parkinson’s disease is a nervous system disorder that affects around 1 percent of people aged 65 years and older. Symptoms usually develop slowly over several years. […]
