Depression has been linked to memory problems, such as forgetfulness or confusion. It can also make it difficult to focus on work or other tasks, make decisions, or think clearly. Stress and anxiety can also lead to poor memory. Depression is associated with short-term memory loss.
The area of the brain dealing with learning and memory — the hippocampus — is sensitive to stress, and tends to be smaller in people with depression. “Diminished hippocampal volume could explain poor recollection,” Dillon says.
People with depression often struggle with short-term memory loss, but they are also at risk of long-term memory problems. A wealth of research, including a study in the British Journal of Psychiatry, has shown that untreated depression significantly increases the risk of dementia.

A depression not only makes a person feel sad and dejected – it can also damage the brain permanently, so the person has difficulties remembering and concentrating once the disease is over. Up to 20 percent of depression patients never make a full recovery.
This disruption in cognitive function that can accompany depression symptoms can sometimes resemble the symptoms of dementia. Although not a diagnosis of dementia, when this occurs it is often referred to as “pseudodementia,” or dementia of depression.
Depression may cause the release of glucocorticoid in the brain, a type of steroid that can damage the hippocampus and other areas of the central nervous system. When this occurs, you may experience symptoms associated with neurocognitive disorder (dementia), such as memory loss.
Depression, nutritional deficiencies, side-effects from medications and emotional distress can all produce symptoms that can be mistaken as early signs of dementia, such as communication and memory difficulties and behavioural changes.
Stress, anxiety or depression can cause forgetfulness, confusion, difficulty concentrating and other problems that disrupt daily activities. Alcoholism. Chronic alcoholism can seriously impair mental abilities.
Memory and other thinking problems have many possible causes, including depression, an infection, or medication side effects. Sometimes, the problem can be treated, and cognition improves. Other times, the problem is a brain disorder, such as Alzheimer's disease, which cannot be reversed.
Potential signs of cognitive decline
Having trouble recalling the names of unfamiliar people. Having difficulty remembering important details of recent events. A change in memory compared with when you were younger. Difficulty following the plot of a television program or book because of memory problems.
First, depressive symptoms often occur among patients with dementia. Second, depression may be a reaction to early cognitive deficits. Third, depression can impair cognitive function leading to a “pseudodementia” presentation. Finally, depression may be a risk factor or early symptom of dementia.
Both studies found that prolonged depressive symptoms in later life (in the decade before dementia onset, and not earlier) are good predictors of increased dementia risk. Other studies have also found similar associations such that having depression in later life can double the risk of developing dementia.
Being depressed increases the risk of developing Alzheimer's disease and other forms of dementia, a new study reports. The study found that men and women with a diagnosis of depression were at increased risk of getting a dementia diagnosis, and the risk persisted even more than 20 years later.
It can impair your attention and memory, as well as your information processing and decision-making skills. It can also lower your cognitive flexibility (the ability to adapt your goals and strategies to changing situations) and executive functioning (the ability to take all the steps to get something done).
Depression and mood disorders are characterized by structural as well as neurochemical alterations in the brain. However, these changes are not permanent, and can be blocked or reversed with behavioral and pharmacological treatments.
According to an fMRI study, decreased brain activity in the hippocampus was reported82 in depressive patients. Reduced gray matter volume and reduced functional activity in the hippocampus would lead to negative emotion and the inability of cognitive processing in depressive patients.
There's growing evidence that several parts of the brain shrink in people with depression. Specifically, these areas lose gray matter volume (GMV). That's tissue with a lot of brain cells. GMV loss seems to be higher in people who have regular or ongoing depression with serious symptoms.
The hippocampus, an area of the brain responsible for memory and emotion, shrinks in people with recurrent and poorly treated depression, a global study has found.
If you keep taking your medicine, there is a good chance that you will start to feel less depressed and that the side effects will decrease. Most people feel that the benefits of antidepressants are well worth the price of living with some side effects.
In neurophysiology, long-term depression (LTD) is an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus. LTD occurs in many areas of the CNS with varying mechanisms depending upon brain region and developmental progress.
Stress, anxiety or depression can cause forgetfulness, confusion, difficulty concentrating and other problems that disrupt daily activities. Alcoholism. Chronic alcoholism can seriously impair mental abilities.
Sometimes, memory loss occurs with mental health problems, such as: After a major, traumatic or stressful event. Bipolar disorder. Depression or other mental health disorders, such as schizophrenia.
