Memory Loss: Causes and Management

What is Memory Loss ?

Memory loss refers to a decline in one’s ability to recall information and past experiences. It is a normal part of aging, but can also be caused by other factors such as head injury, dementia, Alzheimer’s disease, depression, stress, sleep deprevation, or alcohol and drug abuse. The severity and extent of memory loss can vary greatly, and some people may experience more difficulty remembering recent events, while others may have trouble remembering events from the distant past. In some cases, memory loss may be temporary and can be improved with treatment, while in other cases it may be permanent.

Alternative Names of Memory Loss

Memory loss is also known as:

• Amnesia: a condition that affects memory and can result in a complete or partial loss of memories from the past. This can be transient, or permanent.
• Forgetfulness: refers to the inability to remember things that were previously known, or to remember details such as where you put the keys or what someone just said.
• Impaired memory: when one’s ability to recall information is diminished.
• Cognitive decline: a decline in mental abilities, including memory and other mental faculties, that can occur as a result of aging, some medications, illicit drug or alcohol use,  or a medical condition.
• Dementia: a general term used to describe a decline in cognitive function, including memory loss, as well as other symptoms such as disorientation, confusion, and difficulty communicating.To know more about Dementia read our latest article: Dementia : Cause and Management
• Alzheimer’s disease: a progressive neurodegenerative disease that affects memory and other cognitive functions.

It’s important to keep in mind that not all memory loss is the same and that different types of memory loss can have different causes and require different treatments.

Causes of Memory Loss

Memory loss can be caused by a variety of factors, including:

Normal aging: As we get older, our memory and mental abilities can decline. This is a normal part of aging and is often referred to as age-related memory loss.

Normal aging is a common cause of memory loss. As we grow older, our memory and mental abilities can decline, and it can become more difficult to recall information and events. This type of memory loss is often referred to as age-related memory loss or age-associated memory impairment.

However, it’s important to note that age-related memory loss is not the same as dementia, which is a more serious condition that affects multiple aspects of cognitive function. In normal aging, memory loss is usually mild and occurs gradually over time. People with age-related memory loss are still able to live independently and perform everyday activities, although they may need to use memory aids or compensate for their memory loss in other ways.

There are several ways to help minimize age-related memory loss, including staying mentally and physically active, eating a healthy diet, getting enough sleep, and managing stress. Some people may also benefit from memory-enhancing activities, such as learning new skills or practicing mindfulness and meditation.

Head injury : Head injury, especially traumatic brain injury (TBI), can cause memory loss. TBI can occur as a result of a blow to the head or a sudden jolt to the head and neck. The extent and duration of memory loss will depend on the severity of the injury.

Mild TBI, also known as concussion, can cause temporary memory loss, confusion, and disorientation. In more severe cases of TBI, memory loss can be long-lasting and can affect multiple aspects of cognitive function, including the ability to form new memories, recall past experiences, and concentrate.

In the days and weeks following a TBI, memory loss can be particularly pronounced, and people may have difficulty remembering events that happened around the time of the injury. In some cases, memory loss can persist for a long time, and people may need rehabilitation and other forms of treatment to manage their symptoms.

If you or someone you know has sustained a head injury, it’s important to seek medical attention as soon as possible. Early diagnosis and treatment can improve the chances of a full recovery and reduce the risk of long-term complications.

Substance abuse:  Substance abuse, including alcohol and drug abuse, can cause memory loss. Alcohol, in particular, can have a toxic effect on the brain and can interfere with memory function. Chronic alcohol abuse can lead to a condition known as alcoholic brain syndrome, which is characterized by memory loss, disorientation, and other cognitive impairments.

Drug abuse can also affect memory, depending on the type of drug and the method of use. For example, certain drugs, such as marijuana, can impair short-term memory and make it difficult to recall recent events. Other drugs, such as cocaine and methamphetamine, can cause brain damage that affects memory and other cognitive abilities.

In some cases, the memory loss caused by substance abuse may be temporary, and the person’s memory may improve after they stop using the substance. However, in other cases, the memory loss may be long-lasting and permanent, and people may need treatment and rehabilitation to manage their symptoms.

It’s important for anyone who is struggling with substance abuse to seek help as soon as possible. Substance abuse can have serious and long-lasting effects on physical and mental health, and early treatment can improve the chances of recovery and reduce the risk of complications.

Chronic stress: Chronic stress can have a significant impact on memory and cognitive function. When a person experiences chronic stress, their body releases stress hormones, such as cortisol, which can affect brain chemistry and causes changes in the brain that can impair memory.

Chronic stress can also interfere with the formation of new memories and make it more difficult to recall information. This could be due to the effects of chronic stress on sleep quality, or through some other mechanism. It can also affect attention and concentration, making it more difficult to focus and process new information.

In addition to its effects on memory, chronic stress can also have other negative effects on physical and mental health, including increased risk of heart disease, depression, sleep, and anxiety. Chronic stress in mid life is also thought to enhance the risk of developing Alzheimer’s disease in later life.

To help minimize the effects of chronic stress on memory and cognitive function, it’s important to manage stress levels through healthy coping strategies, such as exercise, relaxation techniques, and social support. Maintaining a healthy diet, getting enough sleep, and engaging in mentally stimulating activities can also help to minimize the effects of stress on memory.

If you’re struggling with chronic stress and its effects on your memory and cognitive function, it’s important to seek help. A doctor or mental health professional can help you develop a plan to manage your stress and reduce its impact on your health and well-being.

Depression:  Depression can have a negative impact on memory and cognitive function. People with depression may have difficulty concentrating and focusing, which can make it more difficult to process new information or recall events and experiences. Depression can also affect the formation of new memories and make it more difficult to recall information from the past.

In addition to its effects on memory, depression can also have other negative effects on physical and mental health, including fatigue, loss of interest in activities, joylessness, and decreased motivation.

To help minimize the effects of depression on memory and cognitive function, it’s important to seek treatment for depression. This may involve therapy, medication, or a combination of both. Engaging in mentally stimulating activities, staying physically active, and maintaining a healthy diet can also help to improve memory and cognitive function.

If you’re struggling with depression and its effects on your memory and cognitive function, it’s important to seek help. A doctor or mental health professional can help you develop a plan to manage your depression and improve your mental and physical health.

Vitamin deficiencies: Vitamin deficiencies can have an impact on memory and cognitive function. For example, a lack of vitamin B12 can lead to anemia, which can cause fatigue, memory loss, and other cognitive impairments.

Vitamin B12 is important for the functioning of the brain and nervous system, and a deficiency can cause damage to the nerve cells, leading to memory loss and other cognitive impairments.Similarly, a lack of other B vitamins, such as vitamin B1 (thiamine) and vitamin B9 (folate), can also lead to cognitive impairments and memory loss. Thiamine is important for the metabolism of glucose in the brain, and a deficiency can cause brain damage and memory loss. Folate is important for the formation of neurotransmitters, which are chemicals that transmit signals between nerve cells, and a deficiency can interfere with neurotransmitter function and affect memory. 

To help prevent vitamin deficiencies and their impact on memory and cognitive function, it’s important to eat a balanced diet that includes a variety of nutrient-dense foods. Foods that are high in B vitamins include poultry, fish, dairy products, legumes, and leafy green vegetables. Also, it is estimated that up to 50% of the US population could carry a polymorphism in the MTHFR gene which makes the enzyme that activates folate and for these people special care should be taken to consume only MTHFR safe types of folate including natural folate from foods such as beans and avocados, folinic acid, or 5-LMTHF.  Folic acid can make folate deficiencies worse in people with the MTHFR variant.

If you’re concerned about a vitamin deficiency and its impact on your memory and cognitive function, it’s important to speak with your doctor. They can help you determine if you have a deficiency and recommend the appropriate treatment, which may include dietary changes, vitamin supplements, or other forms of treatment.

Chronic illness: Chronic illness can have a significant impact on memory and cognitive function. Chronic illnesses, such as cardiovascular disease, diabetes, and Parkinson’s disease, can affect the brain and cause changes that impair memory and other cognitive abilities.

For example, cardiovascular disease can affect blood flow to the brain and cause damage to the blood vessels and brain tissue. This can lead to memory loss, confusion, and other cognitive impairments. Diabetes can also affect blood flow to the brain and lead to changes in brain function that affect memory and other cognitive abilities. Even metabolic syndrome, the precursor to diabetes, can lead to blood sugar fluctuations which can damage brain tissue.

Similarly, Parkinson’s disease and other neurodegenerative conditions can cause progressive damage to the brain and lead to memory loss and other cognitive impairments.

To help minimize the impact of chronic illness on memory and cognitive function, it’s important to manage the underlying illness and treat any related symptoms. This may involve medication, dietary changes, lifestyle changes, and other forms of treatment. Engaging in mentally stimulating activities, staying physically active, and maintaining a healthy diet can also help to improve memory and cognitive function.

If you’re struggling with the effects of a chronic illness on your memory and cognitive function, it’s important to seek help. A doctor or healthcare professional can help you develop a plan to manage your illness and reduce its impact on your health and well-being.

Neurological conditions: Conditions such as Parkinson’s disease, multiple sclerosis, and epilepsy can cause memory loss.

There are several neurological conditions that can cause memory loss and other cognitive impairments. Some of the most common neurological conditions that affect memory include:

• Alzheimer’s disease: This is the most common cause of dementia and is characterized by progressive memory loss, confusion, and difficulty with everyday tasks. This can happen as early as midlife, but is more common in the elderly.

• Leafy green vegetables: Foods like spinach and kale are high in antioxidants and nutrients that can help improve brain function and reduce the risk of memory problems.
• Berries: Berries, such as blueberries and strawberries, are high in antioxidants and can help improve memory and cognitive function.
• Fish: Fish, especially those high in omega-3 fatty acids, such as salmon, sardines, and tuna, have been shown to improve memory and cognitive function.
• Nuts and seeds: Nuts and seeds, such as almonds and chia seeds, are rich in healthy fats and antioxidants that can help improve brain function and reduce the risk of memory problems.
• Whole grains: Whole grains, such as oatmeal and brown rice, are high in fiber and can help improve cognitive function and reduce the risk of memory problems.
• Turmeric: Turmeric is a spice that contains a compound called curcumin, which has been shown to improve memory and cognitive function.
• Dark chocolate: Dark chocolate is high in antioxidants and can improve blood flow to the brain, which can help improve memory and cognitive function.

It’s important to eat a balanced diet that includes a variety of foods from each food group, as well as to limit sugar, saturated fat, and processed foods, which can have a negative impact on memory and cognitive function.

If you’re concerned about memory loss, it’s important to speak with your doctor, as there may be underlying medical conditions that need to be treated. They can help determine the cause of your symptoms and recommend the appropriate diet and lifestyle changes to help improve your memory and cognitive function.

What Foods Are Worst  If You Have Memory Loss

While diet is only one piece of the memory-loss puzzle, there are some foods that can make memory loss significantly worse. These include:

• Sugar: Diets high in sugar, especially sugar and starch without any protein, fiber, or good fat to help moderate it’s effects on blood sugar levels, have been shown to increase the likelihood of memory loss and to reduce circulation to the brain. Sugary Cutting back on sugar as well as starchy foods such as white bread, pasta, potatoes, and white rice, can help your body to stabilize blood sugars and reduce memory loss.
• Trans fats: A study presented at the American Heart Association Scientific Sessions shows that eating trans fats reduces a person’s ability to recall words. These fats are found in hydrogenated or partially hydrogenated oils and vegetable shortening.
• Artificial sweeteners: Research has shown that long term use of artificial sweeteners, especially in teenage years, can cause memory loss later in life. These effects were especially noted with saccharin, ACE-K, and stevia.
• Alcohol: The overconsumption of alcohol is directly related to neuronal damage and toxic effects on the brain cells that can lead to memory loss.  The threshold at which normal use becomes overconsumption varies greatly from person to person and at different ages of one’s life. It is important to limit alcohol consumption especially if you  notice negative symptoms or side effects.
• Vegetable oil: Vegetable oils that are high in omega-6 fats such as safflower, corn oil, sunflower oil, and canola oil can upset the balance between omega-6 fats and beneficial omega-3 fatty acids, which can lead to impaired memory and brain function.

Paying attention to your diet and eating lots of fruits and vegetables, with moderate lean protein, good fats, and fiber can help you to protect your memory and your brain health long term.

Differences Between Normal Aging and Alzheimer’s Disease

Normal aging and Alzheimer’s disease are two different conditions, but they can both cause changes in memory and cognitive function. However, there are several key differences between normal aging and Alzheimer’s disease:

• Onset: Forgetfulness and memory loss are normal parts of aging, but they generally occur gradually over time. On the other hand, Alzheimer’s disease typically causes more rapid and severe memory loss and changes in cognitive function.
• Progressive nature: Memory loss and cognitive changes associated with normal aging tend to be mild and stable over time, while Alzheimer’s disease causes progressive, worsening symptoms.
• Other symptoms: In addition to memory loss and cognitive changes, Alzheimer’s disease can cause other symptoms, such as changes in mood, behavior, and communication.
• Impact on daily life: Normal aging may cause some difficulties with memory and cognitive function, but they usually don’t significantly impact daily life. On the other hand, Alzheimer’s disease can significantly affect a person’s ability to carry out daily activities and may eventually lead to a loss of independence.
• Treatment: There is no cure for Alzheimer’s disease, but there are treatments and therapies that can help manage symptoms and improve quality of life. On the other hand, memory loss and cognitive changes associated with normal aging can often be improved with lifestyle changes, such as exercise, a healthy diet, and mentally stimulating activities.

It’s important to speak with your doctor if you’re experiencing significant changes in memory or cognitive function, as early diagnosis and treatment of Alzheimer’s disease can help improve outcomes and quality of life.

Memory Loss : Medical History and Symptoms

A medical history and symptoms play an important role in diagnosing and understanding the cause of memory loss. When a doctor evaluates a patient for memory loss, they typically ask about:

• Medical history: The doctor will ask about past illnesses, surgeries, traumas, medications, and family history of memory loss or other neurological conditions.
• Symptoms: The doctor will ask about the nature of the memory loss, such as when it started, how severe it is, and if it’s getting worse over time. They may also ask about other symptoms, such as confusion, difficulty with everyday tasks, and changes in mood or behavior.
• Substance use: The doctor will ask about alcohol and drug use, as substance abuse can impair memory and cognitive function.
• Lifestyle factors: The doctor may ask about the patient’s diet, exercise habits, and sleep patterns, as well as any stressors or changes in their life that could be impacting their memory.

Based on the medical history and symptoms, the doctor may perform a physical exam, as well as neurological and cognitive tests, to help determine the cause of the memory loss. If necessary, the doctor may refer the patient for additional tests, such as imaging studies or a biopsy, to help diagnose the underlying condition.

It’s important to seek medical attention if you’re experiencing memory loss, as prompt diagnosis and treatment can help manage the condition and improve quality of life.

When to Visit the Doctor for Memory Loss

You should visit a doctor if you are experiencing significant changes in your memory or cognitive function that are affecting your daily life. Some signs that you may need to see a doctor include:

• Forgetting important dates, appointments, or events
• Difficulty remembering recent conversations or events
• Struggling to remember the names of people, places, or objects
• Frequently misplacing things or having trouble finding them
• Struggling to complete familiar tasks or follow familiar routines
• Changes in mood, behavior, or communication
• Difficulty making decisions or solving problems
• Difficulty with spatial orientation, such as getting lost in familiar places
• A sudden or rapid decline in cognitive function

If you’re experiencing any of these symptoms, it’s important to speak with your doctor, who can evaluate your memory and cognitive function and determine if there is an underlying medical condition that needs to be addressed. Early diagnosis and treatment of conditions such as alcohol-related dementia or Alzheimer’s disease can help improve outcomes and quality of life.

How Are MTHFR Mutations and Memory Loss Related?

The MTHFR polymorphism is a small change in the gene that codes for the MTHFR enzyme, which activates folate so that it can be used within your body. This causes the enzyme to work slowly and can create a functional deficiency in active folate. Active folate and an effective MTHFR enzyme are necessary for the formation of neurotransmitters including serotonin, dopamine, and norepinephrine.  Balanced neurotransmitters contribute to all areas of brain functioning, not just mood, and contribute to the formation of new memories and the retrieval of information in your brain. Therefore, having balanced functioning of the MTHFR enzyme is an important step in preserving your memory and cognitive function.

The MTHFR mutation, as well as folate deficiency, have also been associated with increased risk for Alzheimer’s disease.  MTHFR polymorphisms are also associated with addictive tendencies, which can contribute to alcohol related dementia.  It is crucial, in working with memory loss or working to protect your  memory for the future, to balance the functioning of your MTHFR enzyme and ensure that you have functional, optimal levels of active folate.  You can do this by following the steps outlined in the plan set out on this website, or if you would like step-by-step guidance, the MTHFR for Life course is a great place to start.  If you prefer to have extra support, Dr. Amy is available for one-on-one consultations.
