How Schooling Shapes Brains in Parkinson's and Lewy Body Disease

People with Parkinson's disease dementia (PDD) and Lewy body dementia (DLB) have different brain activities. Scientists looked at how much schooling people had. They wanted to see if it affected brain waves in these patients. They checked brain waves in people with PDD, DLB, and healthy older adults. Everyone was split into two groups: those with less education and those with more. In healthy adults, more schooling meant more brain activity in the alpha range. This might mean that education helps protect the brain. But in PDD patients, more schooling led to less brain activity in the alpha range. This could mean that education helps the brain find new ways to work around problems. In DLB patients, education level didn't seem to make a difference in brain activity. So, education might help the brain cope with Parkinson's disease. But it doesn't seem to help with Lewy body disease. More research is needed to understand how education affects the brain in these diseases. Governments should think about investing in early education. This could help prevent cognitive problems in old age. It could also reduce the social and economic costs of these diseases. Brain waves show how the brain is working. The alpha range is important for staying alert and focused. Education might change how the brain uses these waves. In healthy brains, more education means more alpha activity. But in PDD brains, more education means less alpha activity. This could be because the brain is finding new ways to work. People with PDD and DLB have different brain problems. PDD is linked to Parkinson's disease. DLB is a different type of dementia. Both affect how the brain works. Education might help the brain cope with PDD. But it doesn't seem to help with DLB. More research is needed to understand why. Education is important for many reasons. It helps people get jobs and live better lives. But it also affects how the brain works. In old age, education might help the brain stay healthy. It might also help the brain cope with diseases like PDD. Governments should think about investing in education. It could help prevent cognitive problems in old age. It could also reduce the costs of these diseases.
