50 million are currently living with dementia, a figure which is set to increase substantially as worldwide populations age and people live longer. Dementia differs from normal aging in that our cognitive functions, or how we think and remember things about ourselves and others, begin to breakdown. Researchers have some theories as to why this happens and in some specific cases what might prevent it but they simply don't know enough to help the millions of people who suffer from dementia on a daily basis. However, all is not lost, what they do know is that that there may be early warning signs which if detected, which could allow researchers to put treatments in place years before disease onset. It's too early to say with certainty but researchers hope that once we can detect the disease early, we can stop it from progressing completely. Mental health conditions affect 1 in 4 people around the world. Through decades of research, researchers have identified important risk factors for mental health like early stress or neglect, and have built an enormous body of knowledge regarding cognitive and brain changes that go hand in hand with mental illness. This research has typically taken a bird’s eye view - studying groups of people and looking for associations with diagnostic categories like depression. Unfortunately, it has proven difficult to use these insights to make predictions about individuals. At Neureka, they want to change that. They want to conduct the largest and most detailed study of YOU that has ever been attempted. By playing games and telling Neureka how you feel, day by day, they aim to figure out how mental health issues evolve over time. Neureka wants to know why some people are more resilient than others, how emotions like mood, irritability and motivation interact with one another and the environment and how they can kick-start vicious cycles that are difficult to break free from. Participate in Neureka by taking part in their Science Challenges. Science Challenges contain combinations of games and questionnaires that tell researchers things about how your brain works and interacts with the world around you. Take part in the ‘Risk Factors’ challenge to contribute to the science of early dementia diagnosis or ‘Multi-Mood’ to contribute to the neuroscience of depression. The more science challenges you complete, the more achievements you collect and the more you contribute to science Every minute you spend completing science challenges, playing games and completing questionnaires in the app helps researchers move the needle forward in the global fight against Dementia and Depression. Join us and make a difference to science and to people’s lives across the world. We can only make a difference with your help!
