Depression not only depletes your energy and motivation, but it can also bring about various physical and cognitive changes that can impact your day-to-day life. The term cognitive or cognition refers to the mental action or process of acquiring and understanding knowledge through our thoughts, experiences, and senses. People with major depressive disorder (MDD or depression) often notice differences in their ability to plan, problem-solve, and make decisions as a result of the cognitive symptoms of depression. If left untreated, these symptoms can last longer and become more severe over time. Fortunately, treatment is available.
The cognitive model of depression suggests that the presence of negative life events in addition to one’s perception of or reaction to those events can contribute to the development and maintenance of depressive signs and symptoms. The cognitive theory of depression believes that negative cognitions and an underlying all-or-nothing form of thinking contribute to and worsens depression symptoms.1
Moreover, the cognitive-vulnerability stress model suggests that, in cases of negative life events, people who tend to make negative attributions about the cause of said events, themselves, and future consequences are more likely to develop depression.2 This theory goes hand in hand with the hopelessness theory of depression, which predicts that the interaction between negative cognitive styles (ways of thinking) and negative life events causes a sense of hopelessness.3
There’s also a triad of cognitive patterns linked to depression known as the depressive cognitive triad. The cognitive triad of depression connects negative views about the world to negative views about the future to negative views about oneself, from which the cycle starts all over again.
These theories and models help explain the cognitive symptoms of depression, how the disorder impacts a person’s thoughts and behaviors, and how they can be properly addressed and treated with mental health care.
When most people think of depression, they think of feeling sad and down for long periods. They might think of losing your energy, wanting to stay in bed all day, and avoiding people and the things you once enjoyed doing.
However, in addition to these changes in mood and motivation, depression can also affect your ability to think. It can impair a person’s attention, memory, the way they process and understand information, and their ability to make decisions.
Depression can also impact a person’s cognitive flexibility (the ability to adapt one’s goals and strategies to changing situations) and executive functioning (the ability to take all the necessary steps to get something done). To better understand how this mental health disorder impacts a person’s ability to think and problem-solve, below are common cognitive symptoms of depression.
There are many reasons a person might struggle to pay attention or concentrate, such as fatigue or boredom. Depression can also cause these issues.
Reduced attention and concentration are some of the most common cognitive effects of depression, and often people who experience this show some of these signs:
An impaired or inhibited ability to remember things is another example of how depression affects cognition. Learning new things is also difficult with depression, especially since memory is part of acquiring new information.
People who experience impairment in learning and memory might:
Some researchers theorize that the connection between depression and memory problems is due to a lower dopamine reward signaling, which can make it difficult for memories to form.
The executive dysfunction system is also known as the CEO of the brain because of the way it allows you to supervise your thoughts. You use executive functions to manage your life and achieve your goals.
Depression can cause executive dysfunction, which can lead to changes in your abilities to:
This can be stressful, but you are not alone. One study featuring 448 participants found cognitive changes in students with depression. Participants experienced cognitive dysfunction in areas like memory, inhibition control, planning, and flexibility.4
Processing speed, in this case, refers to the rate at which you can acquire information, process it, and then respond. Sometimes depression can slow down this ability, making it difficult for us to process and appropriately react to certain situations.
People with depression who experience slower process speed may:
Research indicates that people with depression have a slower processing speed and reaction times for the things they see, except for sad faces, which generate a faster response. This also suggests that people with depression have a bias toward negative information, which ties back into the hopelessness theory of depression and the cognitive triad of depression we mentioned earlier.
Remember that these cognitive changes do not reflect your intelligence or abilities but are rather a result of depression. Depression cognitive impairment is a common side effect of this disorder that occurs in most if not all people who develop major depression.
Cognitive symptoms of depression can impair one’s ability to complete mental tasks, remember things, learn things, focus, and make plans or decisions. Moreover, these symptoms can manifest themselves in decreased reaction time, difficulty with communication, and reduced motor function.
In other words, depression can make you feel as if your mind is going one mile per hour, which can be stressful for you and your loved ones. Fortunately, help is available.
