When I read an article about a gambler with addiction, I noticed that he often mentioned that when he started to accumulate debts among friends, and loans from banks, he began to eat worse, stopped buying new clothes. He began to live in the Syndrome of Deferred Life. What kind of syndrome is this?



First we need to know the reason why the person is living in a deferred life syndrome.  You have stated that the person has lots of debt and that makes me think that the person don't have the money to buy new clothes and buy decent foods for sustenance due to overspending.

Overspending in terms of most of his money goes to gambling.  As the article stated, with uncontrol urge to gamble, his priority is to gamble and if the person don't get a decent win he will surely be left with nothing.  So in case the person hit a jackpot, this deferred life syndrome will likely be gone, and the person's activities would be more lively and luxurious since he has all the money to treat himself.
