Fronto-striatal connectivity is linked to the dopaminergic motor response in Parkinson's disease. Analyzing DFC we show that his relationship is time-sensitive...

Thank you for the great collaboration @cejdoppler, M. Sommerauer and @annabonkhoff

It will be crucial to be able to perform population screening for iRBD. This paper demonstrates again that it's possible, and using additional measures such as wearables and sensors would make it even easier in the near future.

Seger and colleagues validate an important community-based screening approach to identify and enroll research study participants with iRBD. https://t.co/HScBgOpSIG

The diagnosis of REM sleep behavior disorder as prodromal #parkinsons sx at bedside can be tricky. We don't want to 'overcall it.' An attempt at an algorithm which used PSG-proven iRBD, it examined cost-effectiveness. Early days on important symptom. https://t.co/PeHaNUohl9

Remember the preprint I shared a couple of months ago? The final article is now online 🧠🧮 We describe the screening procedure for the local #iRBD cohort @UKKoeln and provide a calculator with the built-in screening algorithm! Check it out @MDJ_Journal https://t.co/Rb1Do9L6qu

Out now: Our results of the ultra-high-field functional MR spectroscopy (fMRS) study on visual processing & visuo-cognition in people w/ #Parkinson's (PD) compared to healthy controls (HC). https://t.co/Z9NTJutHi0 @EANeurology @fz_juelich @MedPsy_Cologne What did we find? A 🧵..

Excited to share our preprint on a novel screening tool to optimize the identification of subjects with isolated REM sleep behavior disorder from the general population. https://t.co/rcLHpNsmtD @AlineDSeger et al. @UKKoeln @fzj_inm3 A 🧵...

@MTJBetts @ChariteBerlin That’s great, Matt! All the best for you and your family and greetings from parental leave. 😉

[Anja Ophey @anjaophey]

We are incredibly excited - we waited for this moment to come for more than 1 year. Isolated #RBD is known to constitute THE prodromal marker for #Parkinsons and RBD patients are vulnerable to develop cognitive dysfunctions. Let's train their brains!💪🧠 @julia_pauquet @DanSchfbg

FIRST SUBJECT IN! 🧠📋 Today, the first subject for our clinical trial on the effects & mechanisms of cognitive training and a program on a healthy, active lifestyle in patients with isolated REM sleep behavior disorder was enrolled! @MedPsy_Cologne #Neurology @UKKoeln @fzj_inm3

If you are just starting out or considering a career in neuroscience, learn to code! Honestly, pick any language and just learn to do the basics: loops, indexing, conditionals. You don't need much more than that for 90% of workflows.

Huge thanks to all co-authors! @M3kinnerup @MTJBetts @perborghammer @fzj_inm3 @UKKoeln

[Christopher Doppler @cejdoppler]

Very happy to announce that our new paper on noradrenergic dysfunction in Parkinson's disease has just been published in @Brain1878 https://t.co/1OfAlxR2su

However, the individual ratios of noradrenaline transporter density and LC MRI contrast were lower in PD patients, suggesting a pronounced noradrenergic terminal loss relative to cellular LC degeneration in Parkinson’s disease. 🧠
