A Novel MRI Compatible Balance Simulator to Detect Postural Instability in Parkinson's Disease

Conclusions: Deficits in static and dynamic balance control can be detected in PD patients using a novel MRI compatible balance simulator. This technique allows for functional neuroimaging to be combined with balance-relevant tasks, and provides a new means to create insights into the neural substrates contributing to postural instability in PD.

Parkinson's disease is a heterogeneous disorder with both motor and non-motor symptoms that contribute to functional impairment. To develop effective, disease modifying treatments for these symptoms, biomarkers are necessary to detect neuropathological changes early in the disease course and monitor changes over time. Advances in MRI scan sequences and analytical techniques present numerous promising metrics to detect changes within the nigrostriatal system, implicated in the cardinal motor symptoms of the disease, and detect broader dysfunction involved in the non-motor symptoms, such as cognitive impairment.

Conclusion: Anti-CV2 autoimmune encephalitis can present as Parkinsonism with bilateral leukoencephalopathy on MRI. PET scanning can be useful to reveal an occult cancer. Treatment of the cancer may improve the paraneoplastic neurological syndrome without the need of immunosuppressive therapy.

Objective: To investigate the dynamic amplitude of low-frequency fluctuations (dALFFs) in patients with Parkinson's disease (PD) and healthy controls (HCs) and further explore whether dALFF can be used to test the feasibility of differentiating PD from HCs.Methods: Twenty-eight patients with PD and 28 demographically matched HCs underwent resting-state functional magnetic resonance imaging (rs-fMRI) scans and neuropsychological tests. A dynamic method was used to calculate the dALFFs of rs-fMRI data obtained from all subjects. The dALFF alterations were compared between the PD and HC groups, and the correlations between dA...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

A new study has found that lefties ’ brains could be associated with better verbal skills, among other talents. I always knew I was specialBeing a leftie has a genetic component, is linked to better verbal skills and is associated with a lower risk of Parkinson ’s disease, according toa new study published in the journal Brain. Unfortunately for Guardian readers, that ’s leftie in the handedness sense, not political. Fortunately for me, I’m both.The study is a fascinating one, using thousands of brain scans and hundreds of thousands of sequenced genomes to look for associations between genes, brains...
