A study published in Nature suggests that a brain network that controls the execution of actions (SCAN), which was described in 2023, plays an important role in Parkinson's disease. Focusing treatments—such as transcranial stimulation—on the SCAN rather than other brain regions associated with movement could improve their effectiveness, according to the research.
An American team has developed a ‘smart’ computer keyboard that could be used for the early diagnosis of Parkinson's disease. The prototype is a flexible device, linked to a mobile application, whose keys detect slight variations in the pressure applied by the user, allowing for the quantitative analysis of motor symptoms. The study, published in Science Advances, presents the validation of the keyboard with three people with Parkinson's.
In 2050 there will be 25.2 million people with Parkinson's disease worldwide, which represents an increase of 112% from 2021, largely due to the ageing of the population, according to a modelling study published by The BMJ. The number of people living with this disease – prevalence across all ages – per 100,000 inhabitants is expected to increase by 76% – and by 55% when age differences are corrected.
