Can My Memory Loss be Caused by Depression?

Can My Memory Loss be Caused by Depression?

Some people who are struggling with a mental health problem such as depression will experience issues with their memory, becoming confused or forgetful from time to time. But because most of us associate depression with feelings of sadness or hopelessness, it is common for memory problems to be overlooked or considered a symptom of something else. 

Memory Problems Linked to Depression

However, according to an article in The Conversation, cognitive impairments are actually quite common in those suffering from depression. Moreover, an article in MedicalNewsToday explains that depression affects a variety of functions, including memory. 

Depression Symptoms

There are many symptoms associated with depression. Most people will experience some of the following:

  • Feelings of sadness or loneliness
  • Fatigue or no energy
  • Negative thoughts
  • Lack of interest in activities previously enjoyed
  • Short temper or irritability
  • Loss of appetite
  • Weight changes
  • Trouble sleeping
  • Aches and pains
  • Restlessness
  • Confusion or forgetfulness.

In many individuals, it is the working or short-term memory that is affected by depression. Other symptoms such as restlessness, irritability, and fatigue can make it harder to concentrate, and affects the ability to remember things from one moment to the next. 

In older people, issues with memory caused by depression are often first considered to be the onset of dementia. However, over time and left untreated, depression can actually increase the risk for dementia, according to an article published in the British Journal of Psychiatry. 

What Else Causes Memory Loss? 

While there is a definite link between depression and cognitive function, there are also other conditions that can cause memory loss, so it is quite important to not make assumptions. If you are having trouble with your memory and cognitive function, you should speak to your doctor. It is best to rule out other causes of memory loss, which can include: 

  • age-related cognitive decline
  • dementia or Alzheimer’s disease
  • trauma or head injury
  • medication
  • vitamin B-12 deficiency
  • drug or alcohol abuse
  • hypothyroidism
  • brain tumor or infection
  • multiple sclerosis
  • Parkinson’s disease. 

How is the Cause of Memory Loss Diagnosed? 

The counselors at Psych Blossom (find their website here) say that when memory loss is linked to depression, it is often diagnosed during depression therapy sessions. However, many people will visit their doctor when they realize that they are having problems with their working memory. A doctor will ask a series of questions to try to determine the cause. If you are suffering from this, you will likely be asked about when you started noticing problems with your memory and how it is affecting daily life. Doctors will also want to know whether you have been also experiencing feelings of anxiety or depression. 

You might also be asked about any medications you are taking and how much alcohol you drink. Your doctor will also want to know if you have recently been ill or had an accident where you suffered a minor head injury. These questions coupled with some exploratory tests will usually help the doctor to make an accurate diagnosis. You may need to have an MRI, blood tests, or a test to examine your brain activity, known as an electroencephalogram. 


Most people do not realize that their memory problems are linked to their mental health condition. However, research has shown that depression can cause issues with cognitive function. If you are depressed, it may be that this is causing your memory problems. Nonetheless, there are a number of other causes of memory problems, so it is important to get checked out by your doctor to rule these out. If your memory issues are linked to depression, therapy may help.
