Inês Caetano, Liliana Amorim, Teresa Costa Castanho, Ana Coelho, more

European Journal of Neuroscience > 56 > 8 > 5287 - 5298

Daily routines are getting increasingly stressful. Interestingly, associations between stress perception and amygdala volume, a brain region implicated in emotional behaviour, have been observed in both younger and older adults. Life stress, on the other hand, has become pervasive and is no longer restricted to a specific age group or life stage. As a result, it is vital to consider stress as a continuum...
