Depression can cause cognitive impairment, affecting memory, concentration, and decision-making abilities. It’s important to recognize and treat these symptoms, especially in older individuals who may be at risk for Alzheimer’s or dementia.
The connection between depression and cognitive impairment is well known. It is most commonly associated with major depression, but mild to moderate depression can cause some cognitive impairment as well. Depression causes chemical changes in the brain and affects neurotransmitters that are known to regulate mood, including serotonin and dopamine; these neurotransmitters not only impact mood, but can also decrease cognitive abilities. As a result, depression and cognitive impairment can make it difficult to pay attention or focus on the task at hand, harder to remember things, and make it impossible to think quickly or make decisions on the spot.
It is important for individuals, as well as doctors and mental health professionals, to recognize and understand the connections between depression and cognitive impairment, because they are real and can be very frustrating for people undergoing treatment. Memory and concentration problems are two of the most common symptoms of problems with depression and cognitive impairment. People may have trouble listening to others or concentrating while at work, or they may have trouble remembering previously learned information. Getting distracted in the middle of a task and forgetting to complete it is also common.
Additionally, people with depression and cognitive impairment often feel as though they are just thinking slowly. They may sense that other people are talking too fast to be understood and may find it a challenge to keep up with conversations. If they are forced to make a decision, solve a problem or respond quickly, they may find it a difficult or impossible task. All of these issues can quickly impact your work and relationships, so it’s important to discuss these issues with a psychiatrist or psychologist to get treatment. This may include different medications or practicing particular activities and skills to improve cognitive function.
Older people with depression are more likely to experience cognitive impairment than any other group; this can lead to health problems or other problems due to behavioral changes caused by confusion and lack of concentration. It can also make an individual more likely to have Alzheimer’s disease or dementia later in life. In the case of older people, however, it can be difficult to determine how much of the cognitive impairment is caused by depression and how much is the result of simple aging, which can make the condition more difficult to treat.
