The likelihood of any American having dementia of their lifetime could also be far better than beforehand thought. For example, a 2025 examine that tracked a big pattern of American adults throughout greater than three a long time discovered that their common probability of developing dementia between ages 55 to 95 was 42%, and that determine was even increased amongst ladies, Black adults and people with genetic danger.
Now, an excessive amount of consideration is being paid to how to stave off cognitive decline within the ageing American inhabitants. However what is commonly lacking from this dialog is the function that power stress can play in how properly individuals age from a cognitive standpoint, in addition to everyone’s danger for dementia.
We’re professors at Penn State within the Center for Healthy Aging, with experience in health psychology and neuropsychology. We examine the pathways by which power psychological stress influences the danger of dementia and the way it influences the flexibility to remain wholesome as individuals age.
Latest analysis reveals that Individuals who’re at the moment middle-aged or older report experiencing more frequent stressful events than earlier generations.
