Impaired decision-making skills
Depression patients become indecisive as well because they lack the confidence they need to make decisions and maintaining them. Their drowsiness, low energy levels, and slow thinking might further impair their capacity to solve problems, and their lack of interest would make them feel they do not care whether or not issues at work or school are solved. As the disease progresses, they may become either aggressive and unreliable, or unresponsive and absent.
