The study below adds some evidence to the latter claim and found that extended poverty (20 years or longer) exposure also causes premature aging. Perhaps one of the most striking finding was that even highly educated people and\/or young people easily lost their mental prowess when exposed to poverty. This, again, suggests it is poverty that causes the mental decline and the other way around. Of the four explanations proposed by the authors on how poverty causes this mental decline and premature aging, I think the third one is the most salient &#8211; chronic stress and thus elevated cortisol. There are few things more destructive for the brain than cortisol. Serotonin is probably the only other stress mediator that can give cortisol a good run for its money.<\/p>\n<p><a href=\"https:\/\/www.ajpmonline.org\/article\/S0749-3797(16)30329-4\/pdf\">https:\/\/www.ajpmonline.org\/article\/S0749-3797(16)30329-4\/pdf<\/a><\/p>\n<p><a href=\"https:\/\/www.independent.co.uk\/news\/science\/poverty-intelligence-aging-brain-low-income-inequality-a7333506.html\">https:\/\/www.independent.co.uk\/news\/science\/poverty-intelligence-aging-brain-low-income-inequality-a7333506.html<\/a><\/p>\n<p>&#8220;&#8230;<strong>Falling into\u00a0<span style=\"color: #ff0000;\"><a class=\"body-link\" style=\"color: #ff0000;\" href=\"https:\/\/www.independent.co.uk\/topic\/poverty\" data-vars-item-name=\"BL-7333506-http:\/\/www.independent.co.uk\/topic\/poverty\" data-vars-event-id=\"c6\">poverty<\/a><\/span> appears to <span style=\"color: #ff0000;\">make people become less intelligent and become old before their time<\/span>, according to a new study.
