Memory Loss: When To Be Concerned About Memory Decline And What To Do About It
Many people might experience forgetfulness, but when temporary lapses in memory seem to become the norm, it can be easy to assume the worst.
We do want to note that memory loss can happen naturally over time. A bit of memory loss, especially short-term memory loss, can be a normal part of aging and begin to progress when a person is as young as 50. However, extensive memory loss could be a sign of something serious.
Memory loss causes
There are many potential causes of memory loss, most of which might relate to changes in or behaviors that can affect the brain. Some memory loss might be temporary and can be corrected, while other types can be permanent. The severity and long-term implications of memory loss generally relate to the cause(s) behind them.
Below are a few common causes of memory loss that can contribute to your experience:
Statins medications may increase the risk of memory loss or disease
There has recently been a link between statins and memory loss. Statins are known by most as a certain type of medication used for lowering cholesterol, possibly making this finding more impactful. A recent study published by Harvard had mixed results on the severity of this implication—prompting many to seek explicit recommendations from their practitioners.
Other medications or impairment
Many have found that there are many other medications that have been linked to permanent or temporary memory loss. These drugs can include some antidepressants, antihistamines, sleep aids, anti-anxiety medications, muscle relaxers, tranquilizers, and certain stronger pain medications. For this reason, it can be important to report all medications you currently take or have been taking for a long period of time to your doctor when you talk to them about your memory loss.
Most of these medications may not cause memory loss right away. The memory loss that some may experience with the use of these medications can be gradual at first, increasing more quickly over the span of several years. Taking medication and making any sort of defensive lifestyle changes recommended by your physician can be helpful ways to preserve your memory while on certain medications.
Alcohol and substance use connection with memory loss
Long-term alcohol and substance use may be linked to memory loss. It can also lead to a loss or degradation of long-term memories, and you may have trouble remembering things that happened while intoxicated or affected by the substance in question.
Sometimes this memory loss can recede with time if one becomes and stays sober. Short-term memory usually improves with long-term sobriety—however, one may still have trouble recalling parts of the past, particularly points in time when the alcohol or substance use was most severe.
Sleep deprivation leads to memory decline or unusual forgetfulness
The amount and quality of sleep a person gets can both be important. If you frequently wake in the night or don't sleep at least eight hours a day, you may be more likely to have memory problems over time. This sort of memory loss can be temporary and avoidable through the establishment of healthy sleep patterns.
Mental health disorders
Some mental illnesses, such as depression, bipolar disorder, schizophrenia and others, may impact a person’s memory. In these cases, memory loss may or may not be linked to an actual inability to recall information in general. Instead, symptoms may interfere with a person’s memories at a certain time or lessen their likelihood of feeling present enough to form powerful memories.
No matter what, if memory loss associated with mental illness is new or sudden, it may be worth speaking to a doctor about.
Nutritional deficiencies and brain health functions
Nutritional deficiencies can have an effect on how well the brain functions and can lead to problems with memory. The body generally needs to get enough nutrients, including fats and proteins, for the brain to function properly.
More specifically, drastic deficiencies in B1 and B12 can lead to short-term memory loss. Supplements can sometimes support people who are in this situation, possibly allowing memory to return. You may also consider speaking to a nutritionist to see where you can add these important nutrients in your diet.
Injuries and chronic health disorders
Head injuries can sometimes lead to short-term or long-term memory loss. Complete amnesia can occur with a head injury, which is different than memory loss. Memory loss generally only affects a short time period before the accident.
Certain head injuries can also lead to an inability to make new memories and problems with short-term memory. Sometimes head injuries can cause one to forget names and places but remember certain major life events.
The memory loss that can occur with a head injury can be largely unpredictable and may depend on what areas of the brain are affected. However, many might find that memory loss related to a head injury is temporary.
Strokes can also lead to brain damage that can affect memory. A stroke can occur when a blood vessel leading to the brain is blocked or when a blood vessel in the brain ruptures. Unless the stroke is very severe, though, most stroke victims can remember things from the past, especially the distant past. However—they may have trouble remembering things from day to day, or even moment to moment. They might repeat themselves frequently or forget what they had to eat that day.
Finally, other illnesses such as AIDS, syphilis, and tuberculosis can cause memory loss if they become severe or last for a long period of time. These illnesses may cause damage to the brain, which can in turn cause loss of memory.
Dementia and memory loss: Alzheimer’s disease and other types of dementia
One of the leading causes of memory loss is Alzheimer's disease and other types of dementia. Alzheimer's disease typically can cause memory loss over some time, possibly gradually worsening. A person’s short-term memory, in this case, may be the first to falter—then memories of the past can also begin to disappear.
Therapy and supportive treatment regimens prescribed by a provider can help many with the listed conditions to have more fulfilling experiences overall.
Warning signs and symptoms of memory loss
Though the potential causes for short- and long-term memory loss can vary significantly, in many cases, experiencing some degree of memory loss is nothing to be concerned about. However, if you see certain warning signs from yourself or your loved ones, especially if they are sudden, you may want to consult a doctor to determine the cause and extent of the memory loss.
Severe impairment of the mind or memory can be a sign of an underlying cause that requires immediate treatment, so it is often better to be safe than sorry. Below are a few key symptoms you can look out for that might indicate memory loss stems from something bigger than the natural tendency to forget from time to time:
- Sudden memory loss: If memory loss is sudden, this can be a warning sign that something is seriously wrong. The patient may have had a small stroke that went undetected, or another cause could be to blame.
- Inability to perform tasks: Memory loss so severe that it prevents you or your loved one from basic self-care tasks may be cause for concern. A physician can run diagnostic tests to determine possible causes, treating
- Social deficits or changes in behavior: Irritability, lashing out and other behavioral changes that may make a person seem unlike themselves can be a sign that something bigger is going on beneath the surface. Whether directly related to memory loss or not, signs like these can indicate changes in cognitive function or physical wellness.
- Development of mental health symptoms: Extensive memory loss can change a person’s life significantly enough to lead to things like depression or anxiety disorders. Likewise, memory loss that accompanies other symptoms of mental health disorders (such as hallucinations or delusions) may itself be a sign of mental illness.

This can be especially true for those who are experiencing time- or cost-related constraints.
Takeaway
What causes memory loss like in dementia and Alzheimer’s disease?
Memory loss can be caused by a wide range of factors, and it can vary in severity and duration. Some common causes of memory loss include:
- Aging: According to the National Institute of Aging, mild memory changes are a part of the normal aging process. Older adults may experience occasional forgetfulness and slower recall. This is known as age-related cognitive decline and may not be a sign of a more serious condition like dementia.
- Stress and Anxiety: High levels of chronic stress and anxiety can affect memory function. Stress hormones like cortisol can impair memory consolidation and retrieval.
- Depression: Depression can lead to cognitive symptoms, including memory problems. People with depression may have difficulty concentrating and recalling information.
- Medical Conditions: Various medical conditions can impact memory, including:
- Alzheimer's Disease: A progressive neurodegenerative disease that leads to significant memory loss and cognitive decline, blood tests may be able to provide an early diagnosis for Alzheimer’s disease.
- Other Types of Dementia: Conditions like vascular dementia, Lewy body dementia, and frontotemporal dementia can also cause memory problems or mild cognitive impairment. Dementia memory loss may be mild or more severe depending on the individual and type of dementia.
- Traumatic Brain Injury (TBI): Head injuries or brain surgery can result in memory impairments, depending on the severity of the injury.
- Epilepsy: Seizures and certain epilepsy medications can affect memory.
- Thyroid Disorders: Both hyperthyroidism and hypothyroidism can influence cognitive function, including memory.
- Nutritional Deficiencies: Deficiencies in vitamins like B12 and folate can lead to memory problems.
- Infections: Some infections of the central nervous system, such as encephalitis or meningitis, can affect memory and mental abilities.
- Chronic Medical Conditions: Conditions like diabetes and cardiovascular disease can have an impact on cognitive function.
- Medications: Certain medications, including some sedatives, antihistamines, and antipsychotic drugs, can cause memory problems as a side effect.
- Substance Use: The excessive use of alcohol or illegal drugs can impair memory function, both in the short term and long term along with impacting other thinking skills as well.
- Sleep Disorders: Sleep disturbances, such as sleep apnea or chronic insomnia, can affect memory and cognitive performance.
- Psychological Factors: Psychological conditions like dissociation and certain dissociative disorders can lead to memory gaps or memory alterations.
What are the signs of memory loss?
Signs of memory loss can vary in severity and may manifest differently in individuals. Some common signs and symptoms of memory loss include:
- Forgetting Recent Information: Frequent forgetfulness of recent events, conversations, or appointments may be a sign of memory loss. This might include forgetting where you placed your keys, what you had for breakfast, or details of recent conversations.
- Difficulty Remembering Names: Struggling to recall the names of people you know or have recently met may be another sign of a memory-related challenge.
- Repetitive Questions or Stories: Repeatedly asking the same questions or telling the same stories, often because you can't remember that you've asked or told them before.
- Misplacing Items: Frequently misplacing everyday items like glasses, phones, wallets, or remote controls and having difficulty retracing your steps to find them.
- Getting Lost in Familiar Places: Experiencing disorientation and getting lost in familiar surroundings, such as your neighborhood or home.
- Difficulty Following Instructions: Having trouble following multi-step instructions or forgetting the steps involved in completing a task.
- Impaired Judgment: Making poor decisions, especially in financial matters, due to impaired judgment or reasoning abilities.
- Difficulty Managing Daily Tasks: Struggling to manage daily life or everyday tasks such as cooking, cleaning, and personal hygiene, which were previously routine and manageable.
- Confusion About Time or Place: Becoming disoriented about the current date, day of the week, or the location where you are.
- Trouble Remembering Conversations: Difficulty remembering recent conversations, including what was discussed, who was present, or the context of the conversation.
- Decreased Awareness: A decreased awareness of memory problems or an inability to recognize the extent of memory loss, known as anosognosia.
- Personality and Behavior Changes: Memory loss can sometimes be accompanied by changes in personality or behavior, such as increased irritability, mood swings, or social withdrawal.
What is memory loss and decline called?
Memory loss is often referred to as "amnesia." Amnesia is a general term used to describe the impairment or loss of memory, whether it's a partial or total loss, temporary or permanent. Amnesia can manifest in various forms, including transient global amnesia, anterograde amnesia, or retrograde amnesia, and can be caused by different factors, including medical conditions, head injuries, psychological trauma, or substance use disorder. The specific type and cause of amnesia can vary from person to person, and it may affect different aspects of memory, such as short-term memory, long-term memory, or both.
How can I treat my memory loss?
The treatment for memory loss may depend on the underlying cause and severity of the condition. It may be important to identify the cause of memory problems through a comprehensive evaluation by a healthcare provider or specialist. Here are some general strategies that may be considered for managing and treating memory loss:
- Medical Evaluation: If one of your friends or family members is experiencing significant memory loss or having difficulty with familiar tasks, the first step may be to seek a thorough medical evaluation. A healthcare provider can perform a physical examination, review medical history, and conduct cognitive assessments to determine the cause of memory problems.
- Address Underlying Medical Conditions: If memory loss is associated with a medical condition (e.g., thyroid dysfunction, vitamin deficiency, or infection), addressing and treating that underlying condition may improve memory function.
- Medication Review: Some medications can cause memory problems as a side effect. A healthcare provider may review current medications and make adjustments or changes if necessary.
- Lifestyle Modifications: Adopting a healthy lifestyle can support cognitive health and memory function. This includes regular physical activity, a balanced diet, adequate sleep, and stress management.
- Mental Stimulation: Engaging in mentally stimulating activities, such as puzzles, crossword puzzles, reading, and learning new skills, can help keep the brain active and support memory.
- Memory Strategies: Learning memory-enhancing strategies, such as mnemonic techniques and organizational tools, can help compensate for memory difficulties.
- Counseling and Therapy: If memory loss is related to psychological factors, such as stress or depression, therapy or counseling may be beneficial in addressing these issues.
- Medications: In cases of cognitive decline or dementia, healthcare providers may prescribe medications that can slow down the progression of memory loss and improve cognitive function. These medications are typically used in conditions like Alzheimer's disease.
- Memory Rehabilitation: Memory rehabilitation programs, often offered by cognitive rehabilitation specialists, can provide structured interventions and exercises to improve memory function.
Can lack of sleep cause memory loss or Alzheimer’s disease?
A lack of sleep may cause memory problems and cognitive impairment. Sleep can play a crucial role in memory consolidation, which is the process of transferring information from short-term memory to long-term memory. Here's how sleep deprivation can impact memory:
- Disrupted Consolidation: During sleep, especially during the deep stages of non-REM (rapid eye movement) sleep, the brain processes and consolidates the information acquired during the day. This consolidation is vital for the formation of long-term memories. When sleep is disrupted or insufficient, this consolidation process can be compromised, leading to difficulties in retaining and recalling information.
- Impaired Attention and Concentration: Sleep deprivation can result in impaired attention, concentration, and focus. When you're tired, it may become more challenging to pay attention to new information and encode it effectively into memory.
- Reduced Hippocampal Activity: Sleep deprivation has been shown to affect the hippocampus, a brain region crucial for memory and learning. Sleep-deprived individuals may experience reduced hippocampal activity, which can hinder the formation of new memories.
- Memory Interference: Sleep is thought to help clear the brain of irrelevant or redundant information, making it easier to remember essential details. Lack of sleep may lead to memory interference, where new information is mixed up or overwritten by other information.
- Poor Retrieval: Sleep deprivation can also impact the retrieval of existing memories. It may become more challenging to recall previously learned information or experiences when sleep is inadequate.
- Working Memory Impairment: Working memory can be impaired by sleep deprivation. This can affect tasks that require multitasking or problem-solving.
Can memory loss go away?
Memory loss can either be temporary and reversible or persistent and long-lasting, depending on its underlying cause. Temporary memory loss often arises from factors like stress, sleep deprivation, medication side effects, or minor head injuries. In such cases, addressing the root cause or providing appropriate interventions can lead to a return to normal memory function. For instance, memory problems due to stress may be resolved with relaxation techniques, and medication-related memory issues may improve upon medication adjustment. Age-related cognitive decline, considered a normal part of aging, typically leads to mild and non-progressive memory changes.
At what age is memory loss normal?
Mild memory changes are considered a normal part of the aging process, and they typically begin to occur in adulthood. While there is no specific age at which memory decline becomes "normal," it's common for individuals to start noticing subtle changes in their memory and cognitive abilities as they age. These age-related memory changes may include occasional forgetfulness, difficulty recalling names or details, and a slower processing speed for new information. These changes may be referred to as age-related cognitive decline or age-associated memory impairment.
Not everyone may experience significant memory decline as they age, and the extent of memory changes can vary widely among individuals. While mild memory changes may happen, if an individual is experiencing more severe memory problems that significantly impact daily functioning and quality of life, it may be beneficial to have a medical professional determine the cause and appropriate management.
How to improve my memory and brain health?
Improving memory involves adopting a combination of lifestyle changes, cognitive strategies, and healthy habits. Here are some effective ways that may enhance your memory:
- Get Adequate Sleep: Quality sleep is crucial for memory consolidation. Getting uninterrupted sleep each night may allow your brain to process and store information effectively.
- Stay Physically Active: Regular physical exercise improves blood flow to the brain and supports overall cognitive function.
- Maintain a Balanced Diet: A diet rich in antioxidants, omega-3 fatty acids, and brain-boosting nutrients can promote cognitive health.
- Manage Stress: Chronic stress can impair memory function, however, stress-reduction techniques such as meditation, deep breathing exercises, yoga, or mindfulness may reduce stress levels.
- Stay Mentally Active: Engaging in mentally stimulating activities may keep your brain active and challenged. Activities like puzzles, crossword puzzles, reading, learning new skills, and playing memory-boosting games may be beneficial.
- Stay Socially Connected: Social interactions and maintaining relationships can help keep your mind active and reduce the risk of cognitive decline.
- Stay Organized: Use calendars, to-do lists, and reminders to help you stay organized and manage daily tasks and appointments effectively.
At what age can memory loss start?
Memory changes can occur at any age, but the nature and severity of these changes may vary throughout life. In childhood and adolescence, occasional forgetfulness and memory challenges may be associated with learning and academic development but may not be indicative of significant memory loss. Young adulthood is generally characterized by optimal memory function, while middle adulthood (in the 40s to 50s) may bring about subtle memory changes related to stress and lifestyle factors.
However, it is in late adulthood (60s and beyond) that more noticeable memory changes become common. Age-related cognitive decline, which includes mild memory alterations, is considered a natural part of the aging process. While these changes are generally manageable and do not lead to severe memory loss, some individuals may develop more serious memory problems related to conditions like Alzheimer's disease or other forms of dementia in their later years.
Can stress cause memory loss?
Stress may impact memory and contribute to memory loss. When the body is under stress, it releases stress hormones like cortisol and adrenaline, which can affect various aspects of cognitive function, including memory. Here's how stress can impact memory:
- Impaired Concentration: Stress can lead to reduced concentration and focus, making it challenging to pay attention to and encode new information effectively.
- Disrupted Sleep: Chronic stress can interfere with sleep quality and quantity. Inadequate sleep may impair memory consolidation, making it difficult for the brain to process and store information.
- Stress Hormones: The release of stress hormones, especially cortisol, can affect the hippocampus, a brain region critical for memory and learning. Elevated cortisol levels can impair the functioning of this region, potentially hindering memory formation and retrieval.
- Memory Retrieval: Stress can also impact the retrieval of existing memories. In stressful situations, people may find it more challenging to locate stored memories or recall specific information.
- Memory Interference: Stress can lead to memory interference, where new information is overshadowed by stress-related thoughts or emotions.
