General | Latest Info

Sometimes, it is difficult to get out of bed. Under the fog of depression, daily tasks are just tedious, they can seem purposeless. Moving through routines is a struggle. Happy things appear mute, and bad news sounds even worse. Depression affects how people feel. But it can also change how they think. When I see patients, they complain of memory problems, says Carrie Holmberg, postdoc in Psychiatry and behavioral sciences at Stanford University who studies mood disorder. Patients may have trouble finding their keys or retaining information theyve read in a book. People often point to just not being able to function as well. These anecdotal reports reflect a growing body of research showing that depression can affect memory and cognition in diverse and surprising ways. Depressed people have trouble remembering fine details of events theyve experience. General experiences, like vacation, come to mind easily but not specifics, like enjoyable meals from vacation. People prospective memory, or remembering to carry out planned activity in the future, also suffer from depression. It is harder to remember to return library book or take daily medication. While details and prospective memories take a hit, there is no trouble recalling bad memories. Healthy, non - depressed people usually have better memory of positive events than neutral or negative events, says Daniel Dillon, assistant professor of Psychiatry at Harvard University. Meanwhile, depressed people have stronger recall of bad memories. In Depressed folks, people think negative memory improves, but really, positive bias has decrease, Dillon say. Its obvious to people, and more obvious in clinical interview, you have this dominant negative recall. In 2014, researchers examined negative cognition in people who were formerly depressed and groups who never had depression. People who previously had depression were better at remembering negative adjectives from selection of words than group who had never been depress. Scientists conducting research in 2007 examined the role of positive memory in mood regulation, finding that depressed people's moods worsen when encouraged to recall happy memories. When people who were formerly depressed recall happy memories, their sad moods do not change. Brain may reveal some clues about depression hold over memory. The area of the brain dealing with learning and memory hippocampus is sensitive to stress, and tends to be smaller in people with depression. Diminish hippocampal volume could explain poor recollection, Dillon say. In addition, ruminative thoughts characteristic of disorder could make it hard for people to concentrate on other tasks. Rumination, or fixating on upsetting situations or events, occupies neural resources that the brain could spend on other things, like memory. Those findings may not PROVIDE the full picture. The Small hippocampus does explain the emotional component of memory problems. There is no reason it would disrupt positive memories, explains Dillon. What's more, some people prone to depression may have smaller hippocampi before developing disease. We still have poor functional understanding of what is going on with memory and depression, says Dillon.

Other causes of memory loss

Memory loss due to depression is typically managed with regular counseling or therapy and antidepressants. Leading an active lifestyle and getting involved in your community can also elevate your mood. You can also manage your memory loss by using memory aids. Depending on your needs, this could mean using alarm clocks to keep track of time, color - coding household items, or placing safety notes with instructions on appliances. You may also consider getting a home care provider to help you as you need You may also consider joining a support group. Medications that can improve memory and brain function in people with Alzheimer's disease or other neurological disorders are also available.

Heres the science

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. It doesnt affect other types of memory, such as long - term memory and procedural memory, which control motor skills. Feeling sad, anxious, numb, or hopeless Loss of interest in activities or hobbies, having little energy and feeling fatigue, feeling restless or irritable Feeling shame, guilt, worthlessness, or powerlessness Loss of appetite and drastic changes in weight, having trouble sleeping or sleeping too much thinking about death or suicide, having physical problems, such as headaches, stomachaches, and back pain


Other causes of memory loss

Other reasons you may experience memory loss can include the following: normal age - related memory loss is common and manageable. One example of this is forgetting where you put your glasses but remembering later in the day. Alzheimer's disease is the most common form of dementia. It can cause progressive, irreparable brain damage and memory loss. Mild cognitive impairment can alter thinking skills and eventually progress to Alzheimer's disease or other forms of dementia. Minor head injury or trauma can trigger slight memory problems, even if you do lose consciousness. Forgetfulness is a potential side effect of certain medications. Brain tumors or brain infections can affect your memory or trigger dementia - like symptoms. Vitamin B - 12 deficiency can create problems with your memory. This is because youre not maintaining healthy nerve cells and red blood cells. Alcoholism or drug abuse can impair your mental state and abilities. This can also occur when alcohol interacts with medications. Hypothyroidism slows your metabolism, which can lead to memory problems and other issues with thinking. Brain or nerve damage caused by diseases such as Parkinsons disease or multiple sclerosis can cause memory problems. A 2013 study found that people with depression have a greater risk of developing Parkinsons disease. Electroconvulsive therapy can cause memory loss. Ect alters brain chemistry, which can reverse symptoms of depression and other mental illnesses. If you have ECT, your doctor will perform it while youre under general anesthesia. During ECT, your doctor sends small electric currents through your brain, triggering a brief seizure. People can experience confusion and short - term memory loss after receiving ECT treatments.

What can you do?

Memory loss isnt simple thing, and there are many factors at work when considering the process of memory loss. There are four different types of Memory, Sensory, Short - Term, Working and Long Term Memory. Short - Term Memory Short - Term Memory loss is one of the first symptoms of Alzheimer's disease. You might recall your loved one asking the same question multiple times in the course of a day or couple of days. This is commonly described as inability to recall information that was just recently given to you. The amount of time concerning Short - Term can be from a couple of seconds, up to a few days. Sensory Memory Sensory Memory is considered the shortest term memory. It usually is only 3 seconds and it relates to recalling sensory experiences. Sensory Memory is often not referred to so much in detecting Alzheimers because it is subtle and these memories are too short. Working Memory Working Memory is also noticed in early stages of Alzheimer's disease, as it is closely linked to Short - Term Memory. Working Memory is what allows our brains to keep limited amounts of information stored up long enough to use it. It helps us to process our thoughts and to form plans, as well as to develop ideas. As you can see, Short - Term Memory and Working Memory work together. Long - Term Memory Long - Term Memory is usually visible in Alzheimer's patients later on in diagnosis. These memories are from few weeks to early memories from life. The process of Memory moves from Sensory to Short - Term to Long - Term. This explains why Long - Term Memory is last to be affected by disease.


Other causes of memory loss

Your doctor will perform a physical exam and ask you questions to help them identify the cause of your memory loss. This can also help them determine the extent of your memory problems. Your doctor may want to know: when you started experiencing memory problems and for how long youve been feeling depressed, anxious, or sad recently, if youre taking prescription or over - counter drugs regularly and at what dose if you start new medication, what tasks are difficult to start or complete how youve treat your memory issues and if it has work how often and how much alcohol you drink if you injured your head or had accident if you were recently ill if your daily routine has change your doctor may also evaluate your memory and thinking skills with short question - and - answer test and perform electroencephalogram to test your brain activity. They may also run blood tests and imaging tests of your brain, such as MRI, to help them make a diagnosis. They could also refer you to a specialist, such as a neurologist or psychiatrist, for diagnosis.

Methods

A lot of the connection between depression and memory loss has to do with how our body handles stress. The link between stress, depression, and physical fatigue is quite cyclical. When someone is experiencing greater amount of stress, they can often feel stuck, leading to a depressive state, says Katie Cunningham, Chicago - base therapist at Mercy Home for Boys and Girls. When you experience chronic stress, your body releases high amounts of stress hormones cortisol and adrenaline to cope, which has a knock - on effect impacting how the rest of your body functions. In terms of your mental health, sustained cortisol levels can create imbalance of certain key neurotransmitters that impact mood, says Cunningham, which can then impact your mood, sleep, and even memory. When it comes to impaired memory and depression, imbalance of neurotransmitters dopamine and adrenaline are part of the problem here, says Teralyn Sell, PhD, licensed psychotherapist. Dopamine and adrenaline are in charge of your concentration, focus, and overall drive; if you have dopamine imbalance, memory could be something that you struggle with. Depression also damages brain cells, says Dorothy Reddy, MD, owner of Neurogenex. This damage can lead to actual shrinking of the hippocampus, part of the brain responsible for your emotions and processing memories impair its function. A 2013 study found that people with depression struggle to identify objects on screen that they have seen before or similar to those they have seen before. This might not sound like a big deal, but it means that their brains couldnt properly recognize patternsa key mechanism for storing memories. Thuston says memory issues she faced were incredibly isolatingwhich made her depression even harder to cope with. You start to lose your sense of self and depression is already making you feel weird and out of sorts, but when you ca remember certain conversations or events, you really start to question your identity, she say.

Measures

Stressful life events are believed to contribute to the development of human psychopathologies including anxiety and depression, as well as cognitive impairment. Although there exists a large body OF evidence demonstrating the negative impact of stress on emotional symptoms including depression, anxiety and cognitive impairment, however, studies investigating the role OF stress in comorbid prevalence OF anxiety, depression and cognitive impairment in humans, or co - occurrence OF anxiety and depression - like behaviors as well as learning - memory impairment, in animals are limited. Although impressive mechanistic insights have been offered by several groups, with regard to co - occurrence of anxiety - and depression - like behaviors in animal models, studies addressing underlying biology OF stress - induce co - occurrence of depression, anxiety and cognitive impairment are scarce. In the last few years, using a variety of animal models, we have focused on examining mechanistic basis for co - occurrence OF anxiety, cognitive impairment and hypertension,. More recently, we have reported that direct pharmacological induction OF oxidative stress in rats causes anxiety - like behavior and learning and memory impairment while antioxidant treatment prevents these behaviors, suggesting a causal role OF oxidative stress in this co - occurrence. While these observations are interesting, important question has emerged - whether induction of psychological stress is associated with pathogenesis of depression. These behavioral and biochemical consequences are similar to those produced upon pharmacological induction OF oxidative stress? Therefore, in the present study, we have examined behavioral and biochemical outcomes OF application of chronic stress in rats using a social defeat model. Social stress in rats is known to induce long - lasting, adverse physiological, behavioral and neuronal deficits, which seem to resemble certain human psychopathologies OF depression and anxiety. The Ethologically relevant animal model of social stress used for studying the link between stress and psychopathologies is the resident - intruder paradigm. This model involves intimidation and aggressive encounters by large, aggressive male rat toward smaller male rat, and is regarded as one OF most robust models OF Post - traumatic stress disorder, depression, and other stress - related illnesses, and hence is considered to be OF translational relevance. Socially defeated animals reportedly demonstrate social avoidance for weeks after the last social defeat session, and also exhibit depression - and anxiety - like behavioral abnormalities as well as cognitive impairment. Simultaneous occurrence of these behaviors in this model has never been examine. Therefore, in the present study, using this animal model, we have studied the effect of social defeat induced stress, on depression - like behavior, anxiety - like behavior and cognitive impairment as well as the status OF oxidative stress in rats. Oxidative stress has been reported to modulate several behaviors, including learning and memory function, anxiety -, depression -, mania -, nociceptive - and schizophrenia - like behaviors. We also measure the effect of social defeat - induced stress on oxidative stress within three critical brain areas, considered vital for depression, anxiety and cognition, namely, hippocampus, amygdala and prefrontal cortex.

The Link to Memory

Stress response helps you confront life - threatening situations, and its benefits extend to psychological functions like memory. This notion is verified in research, although there are caveats. Everyday anxiety can help you remember things better, according to a study published in Brain Sciences. Researchers split participants who had levels of anxiety into two groups: those with low and high anxiety. No participants had clinically significant levels of anxiety. Two groups were asked to answer questions about spelling or meaning of words overlaid onto neutral images, like house, or negative images, like car accident.S Memory performance didnt differ based on anxiety levels, but the study found that the group with higher anxiety was able to remember words displayed over negative images. Their memories were more emotionally tint, says study co - author Myra Fernandes, and, as result, render more memorable. The study verifies previous research suggesting that emotional content can strengthen memories. Of course, there is a limit to that effect. To some degree, there is an optimal level of anxiety that is going to benefit your memory, according to Fernandes. But we know from other research that high levels of anxiety can cause people to reach tipping point, which impacts their memories and performance. Excessive anxiety can exhaust your body and undermine benefits associated with stress response. Chronic stress can lead to physical problems like headaches, breathing problems, and increased risk of hypertension, heart attack, and stroke. There is also negative psychological impact, such as on your memory.

When Memory Loss Leads To Depression

You 've probably heard of a lot of different symptoms of Depression, but Memory Loss may not be one that you 've heard of before. When people experience Memory Loss, they are quick to jump to conclusions about what cause it could be. And they usually include very serious conditions such as Alzheimer's. However, Memory Loss can be caused by many other problems that don't necessarily have long - term effects on your memory. One of these causes is Depression. There was extensive study conducted at Brigham Young University to investigate the impact of Depression on Memory. They tested almost hundred adults to find what their results would be doing pattern separation test. A study found that the higher level of Depression score of participant, lower the score they receive on the pattern separation test. Researchers believe that when someone is suffering from Depression, they also experience higher levels of memory interference than they would if they were not experiencing symptoms of Depression. Memory interference is when a person is unable to take in and recall new information because of past situations or experiences that they are dealing with. In the example of depression, because someone is experiencing changes in their thought pattern, energy levels, and motivation, they are unable to really take in and recall new information in the same way that they would otherwise. In a sense, they are not able to pay attention in the same way that they would if they were not depress. After the results of study, researchers believe that a process called pattern separation is damaged when someone is experiencing Depression. This process is what allows people to different situations and things that are similar to each other. With this process not working correctly, someone with depression is not able to recall details of a situation that would help them to separate it from anything else. In a sense, memories blend together because the Depression did not allow them to pick up enough different things to separate them from each other. So there's nothing that stands out to them about information that makes it easy for them to recall. On top of that, researchers found that the hippocampus, which is responsible for memory, has decreased growth rate in situations of Depression. The hippocampus is also an area of the brain that grows new brain cells. Therefore, when someone is living with Depression, actual ability of their brain to take in and recall new information is negatively impact.
