Scientists usually use animal models when studying Parkinson's disease because these models mimic the disease well. They are ...

Newly-discovered markers in peoples’ blood can help identify the earliest signs of Parkinson’s disease years before symptoms start, Swedish researchers said Thursday. A blood test for these markers ...

For decades, Parkinson’s disease has been diagnosed only after tremors, stiffness and slowed movement are already disrupting daily life. Now a wave of research suggests a simple blood draw could ...

Cognitive decline and anxiety in Parkinson's disease are often only recognized at a late stage, yet they can greatly impact people's lives. Research by Marit Ruitenberg focuses on new tests and ...

Two trained dogs learned to detect Parkinson's disease by sniffing scent samples from human skin. They were part of a study aiming to improve early diagnosis of the condition. Bumper and Peanut ...

Many people think of a tremor as the quintessential warning sign of Parkinson’s disease. But other symptoms — many of them not involving changes in movement — can appear much earlier than what’s known ...

A team led by researchers at Chalmers University of Technology, Sweden, has succeeded in identifying biomarkers for Parkinson's disease in its earliest stages, before extensive brain damage has ...

Parkinson’s disease is a progressive neurodegenerative disorder with both motor and non-motor symptoms. Mental and behavioural non-motor symptoms such as cognitive impairment, sleep disturbances, ...

For over a century, the assessment of motor and cognitive abilities in Parkinson’s disease (PD) has relied primarily on in-person testing methods. Despite the importance of motor and cognitive ...

Researchers develop a non-toxic Parkinson's disease model using the TMEV virus, proving viral infections can trigger dopamine neuron loss and gait issues.

A cross-sectional study published in PM&R found that people with early-stage Parkinson's disease who regularly performed ...
