Cortisol, DHEA, and depression in the elderly: the influence of physical capacity

Abstract: Major depressive disorder (MDD) is a public health problem and the second cause of years lived with disability after lower back pain 1 . The neurobiology of depression has not yet been completely understood, but there is evidence indicating that stressful life events and dysregulation on the stress physiology, especially in the hypothalamus-pituitary-adrenal (HPA) ABSTRACTObjective: Major depression have been associated with cortisol and dehydroepiandrosterone (DHEA) changes in old depressed patients.

“…Higher levels of BDNF (brain-derived neurotrophic factor), which has been shown to improve synaptic plasticity and long-term memory, may decrease the risk of dementia [17]. Dementia and depression in older adults are also associated with changes in hormone levels, such as cortisol and dehydroepiandrosterone (DHEA) levels [18]. Despite the important roles of these biomarkers, the specific effects of HT on the above-mentioned biological markers remain largely unknown.…”

“…DHEA is secreted by the adrenal in a pulsatile way, accompanying the diurnal rhythm similar to that of cortisol, being stimulated by corticotrophin releasing hormone (CRH) and adrenocorticotrophic hormone (ACTH) [22].…”

“…Os resultados dos artigos analisados mostraram que a eficácia da atividade física no tratamento da depressão em idosos funciona de maneira proporcional inversa, pois o indivíduo mais ativo fisicamente apresenta menor probabilidade de desenvolver doenças e comprometer a qualidade do envelhecimento 14,22,28 . Outra descoberta foi a presença de baixos níveis de cortisol controlados por meio de exercício físico, o que também diminui o risco de depressão nos idosos 11 .…”

“…A depressão tem sido associada a alterações nos níveis de cortisol e dehidroepiandrosterona (DHEA) em idosos depressivos. As análises de uma pesquisa evidenciaram que a prática física modula a relação entre depressão e os níveis de cortisol 11 .…”
