Depression and anxiety can affect the body in many different ways. They both wreak havoc on the person’s mental state and physical wellbeing. But can depression and anxiety cause memory loss? If so, how? The way that depression and anxiety tend to affect the body can interrupt the formation of new memories. Understanding the facts about depression, anxiety, and memory formation can help someone to see how the two disorders tend to affect memories, as well as how they can be treated.

These symptoms and the intense bodily responses to the symptoms of anxiety can make it extremely hard to live life normally day to day. Those who suffer with anxiety tend to do things to avoid triggering their anxiety from flaring up, making socialization and daily living difficult.
12 nofollow noopener noreferrer3>Depression is a condition that can affect the way you feel, how you think and how you act. It can cause major feelings of sadness and loss of interest in activities that were once enjoyable. The disruptions to life that depression can cause can have a huge impact on a person’s life. It can cause isolation, changes in behaviors, and if left untreated, depression can lead to far worse consequences. Fortunately, both anxiety and depression can be effectively treated.
When it comes to the formation of memories, there are generally 3 steps to creating them. The first step of memory formation is encoding. During this phase, meaning is attached to one of the five senses (touch, smell, hearing, sight, or taste).
The next step in memory formation is storage. This means the brain stores the memories in small portions and in different areas for recall later on.
The final step is called recall. This is when the brain pulls the memories back out. Those small chunks are pulled together from their storage locations, they then come together and form what is known as a memory. During this process, nerve pathways that were created when the memory was formed are activated. As an example, when you smell cooking in a restaurant it brings you back to grandma’s kitchen when you were a kid. Depression and anxiety can cause the loss of some of these memories due to the body’s response to these conditions.
When you experience depression and anxiety, it throws the body into what is known as the “fight or flight” response. This means the body is trying to either stand and fight the real or perceived threat, or run from it. Signals are sent from the eyes and ears into the brain, and the emotional processing center of the brain then determines if it is a threat. Adrenaline is then pumped throughout the body, causing higher pulse rate, rapid breathing, and sensory changes. From there, if the perceived danger still exists, cortisol is released. This is a stress hormone, and once the danger has passed and the brain processes that it is gone, levels will diminish.
When the body goes into fight or flight due to anxiety and depression, it can disrupt the normal functionality of the brain. Depression and anxiety can cause memory loss during this response to real or perceived threats. The body is so focused on fending off danger that it is not processing new memories or focusing on anything other than fighting off the threats.
Can depression and anxiety cause memory loss? The short answer is yes. There have been many studies done on the subject matter, and there are many studies still in the works. However there have been some results showing that those who suffer from depression have been known to have short term memory loss. There are a few instances where the memory loss affects long term memories as well.
The link between depression and dementia has also been noted in medical journals. Anxiety can also impact how memories are formed. Because this condition is so taxing on the body, it can make it difficult to recall childhood memories. Untreated depression and anxiety can have a huge impact on memory loss.
Anxiety and depression can cause major disruption to your everyday life, and can make it extremely difficult to function normally. Leaving these two conditions untreated can exacerbate the symptoms, and make the disruptions far more taxing on your quality of life. If you or a loved one are struggling with depression and anxiety, there is help.

Yes, depression and anxiety can absolutely contribute to memory problems, and this is more common than many people realize. When someone is struggling with anxiety or depression, the brain is often overwhelmed by stress, emotional fatigue, and constant mental strain. This makes it harder for the brain to focus, process information, and form new memories effectively.
Anxiety places the brain in a heightened state of alertness, while depression can slow cognitive functioning and reduce motivation. Both conditions disrupt attention and concentration, which are essential for memory formation. As a result, many people experience forgetfulness, difficulty recalling details, or feeling mentally “foggy.” The good news is that these memory issues are often treatable once the underlying mental health conditions are properly addressed.
Anxiety affects memory largely because it keeps the brain stuck in a state of worry and hypervigilance. When someone is anxious, their mind is often focused on perceived threats, worst-case scenarios, or intrusive thoughts. This makes it difficult to pay attention to what is happening in the present moment.
Since memory begins with attention and encoding, anxiety can interrupt the brain’s ability to store information properly. People with anxiety may find themselves rereading the same sentence multiple times, forgetting conversations, or struggling to retain new information because their mental energy is being consumed by stress. Over time, chronic anxiety can create ongoing cognitive exhaustion, making memory recall even more difficult.
Depression can impact memory by slowing down brain function and interfering with motivation, focus, and emotional processing. Many individuals with depression experience what is sometimes called “brain fog,” where thinking feels slower, concentration is harder, and recall becomes less sharp.
Depression also affects neurotransmitters such as serotonin and dopamine, which play important roles in mood regulation and cognitive functioning. When these chemicals are imbalanced, memory formation and recall may suffer. People with depression may struggle with remembering appointments, completing tasks, or recalling details from daily life. In more severe cases, depression can even affect long-term memory and create a sense of emotional numbness or detachment from past experiences.
Memory formation happens in three main stages: encoding, storage, and recall. Encoding is when the brain first takes in information through the senses. Storage is when that information is organized and saved in different parts of the brain. Recall is when the brain retrieves those stored pieces and brings them together as a memory.
Depression and anxiety interfere most with the encoding stage. If someone is distracted by fear, sadness, or emotional distress, the brain may not fully process what is happening. If the memory is never properly encoded, it becomes much harder to store or recall later. This is why people often feel like they are forgetting things—not because the memory is gone, but because it was never fully formed in the first place.
The fight-or-flight response is the body’s natural survival mechanism. When the brain senses danger—real or perceived—it triggers the release of stress hormones like adrenaline and cortisol. This increases heart rate, raises blood pressure, and prepares the body to respond to a threat.
While this response is helpful in true emergencies, chronic anxiety or severe depression can keep the body in a constant state of stress. When the brain is focused on survival, it prioritizes immediate safety over long-term thinking and memory processing. This can make it harder to concentrate, learn new information, and recall memories. Essentially, the brain is too busy trying to manage stress to function normally.
In many cases, the memory issues associated with anxiety and depression are temporary and improve with treatment. However, untreated or severe mental health conditions over long periods can have more lasting cognitive effects.
Research has shown connections between chronic depression and increased risk of cognitive decline later in life. Anxiety can also contribute to persistent memory difficulties if stress remains unmanaged. This is why early intervention is so important. The sooner someone receives care, the better the chances of restoring emotional well-being and cognitive functioning.
No, memory problems caused by depression or anxiety are not the same as dementia, although they can sometimes feel frighteningly similar. Depression-related memory issues are often due to poor concentration, slowed thinking, and emotional exhaustion rather than permanent brain damage.
Dementia involves progressive neurological decline that worsens over time. In contrast, cognitive symptoms from anxiety or depression often improve significantly with proper treatment. If someone is experiencing memory loss, it is always important to speak with a healthcare professional to determine the cause and rule out other medical concerns.
Yes. Treating anxiety and depression often leads to major improvements in memory, focus, and mental clarity. When stress levels decrease and mood stabilizes, the brain can return to healthier patterns of functioning.
Treatment may include therapy, lifestyle changes, medication, or structured mental health programs. As emotional health improves, many people notice that they are able to think more clearly, remember details more easily, and feel more present in daily life.
If memory loss is interfering with daily functioning, relationships, school, or work—or if it is accompanied by severe anxiety, depression, hopelessness, or emotional distress—it is important to seek professional support.
Memory difficulties can be a sign that mental health symptoms have become overwhelming. A trained provider can help identify the root cause and recommend appropriate treatment options. No one should have to struggle alone, especially when effective help is available.
