12 Common Memory Loss Causes 2023

To live a healthy and happy life, you need to be aware of the most common memory loss causes and try to eliminate them as soon as possible.

Almost everyone has experienced a degree of memory loss in their lifetime. It can be something as simple as forgetting where you put your house or car keys.

It can also be as serious as completely forgetting past experiences or failure to recall facts.

Episodes of memory loss are often associated with the development of dementia, especially as a person ages.

While this illness is responsible for multiple cases of memory loss, dementia is not always the sole cause. There are other reversible factors that can also stimulate memory loss.

The Most Common Memory Loss Causes

1. Stress

Too much stress may be one of the reasons you forget things. Stress overloads the mind and if left untreated, it can result in a myriad of issues including depression, diabetes, high blood pressure, brain drain, distractions, etc.

Persons undergoing stress are always tense, finding it difficult to focus; hence, the ability to remember suffers. Moderate stress often triggers short-term memory problems.

Exposure to chronic stress may escalate the risk of developing dementia.

It’s important to employ effective stress management strategies to enrich memory. This also helps to maintain and improve the health of the body, brain, and the quality of life.

2. Medications

Several over-the-counter and prescription medicines are among the leading memory loss causes. Possible meds that may impair memory include:

  • Antihistamines
  • Muscle relaxants
  • Antidepressants
  • Anti-anxiety medicines
  • Sleeping pills
  • Diabetes medication
  • Cholesterol-lowering medicine
  • Tranquilizers
  • Some painkillers especially the ones that doctors administer after surgery, etc.

When seeing different doctors for various conditions, it is important that each professional knows the complete list of medication you are on. It’s the only way to avoid taking medicines that will interact with the ones that you are already taking.

You can also ask your physician whether he or she can adjust the medications you are taking to reduce confusion and forgetfulness.

3. Alcohol and Drug Abuse

Chronic alcoholism and use of illicit drugs can affect your memory. From blacking out when you overindulge to amplified risk of dementia later on, alcohol and drugs have both instant and long-lasting memory loss effects.

Alcohol causes memory loss because it alters the hippocampus activities in the brain. Heavy drinking and the use of hard drugs interfere with the ability to create fresh long-term memories.

Studies show that men who drink heavily end up showing signs of mental decline years earlier than light drinkers.

The two are also known to be the cause of other health issues like liver failure, anemia, heart diseases, and so forth.

4. Nutritional Deficiency

nutritional deficiency
Your diet plays an important role in your ability to keep information and recall things. Lacking certain vitamins in the body are among the common memory loss causes that people experience.

An example is B12 an essential B vitamin that assists with regular nerve function.

When you lack this vitamin, it is easy to experience memory issues. In some cases, vitamin B12 deficit has shown symptoms that are easily mistaken for dementia.

The solution is to make sure you are getting enough B12 vitamin. You can get this from many sources like:

  • Fish
  • Dairy products
  • Meats
  • Foods fortified with vitamin B12

5. Traumatic Brain Injury

traumatic brain injury can cause memory loss
Memory issues are common in individuals who have TBI (traumatic brain injury). The injuries can damage sections of the brain that handle remembering and learning.

Generally, TBI affects newer memories more than the older ones. Some people may have problems remembering the exact cause of the injury. This means that the brain does not store specific injuries as a series of memory.

A majority of traumatic brain injury victims may not be able to store memories for some time after the injury.

Post-traumatic amnesia refers to the loss of consciousness from the TBI moment. It can last for a few minutes, weeks, or several months, depending on the severity of the brain injury.

6. Grief

Grief is amongst the emotional memory loss causes that affects many people. When you lose someone or even something you love or feel closely connected to, your body will use up lots of emotional and physical energy as a coping mechanism.

This may end up reducing your ability to focus on current events or people around you.

Consequently, your memory may suffer. A person needs time to process grief.

To some extent, grief is similar to depression, only that it stems from an acute loss or specific situation.

Depression, on the other hand, may occur without any particular cause. Support groups and individual counseling can help you successfully deal with grief.

7. Smoking

Whilst some people smoke for fun, cigarettes can harm memory. This is because smoking reduces the amount of oxygen that travels to the brain.

Studies reveal that smoking, particularly during midlife, causes poor memory.

Additionally, it makes it harder for you to learn and think. Smoking when you are over thirty years damages blood vessels in your brain and the rest of the body.

Scientists recognize smoking as a top dementia risk factor. Researchers also conclude that people who smoke are at higher risk of heart diseases.

It is best to quit smoking if you want to enjoy better functioning memory and overall health.

8. Mild Cognitive Impairment (MCI)

MCI is at the top of the list when it comes to common cognitive memory loss causes. This is when you experience a decline in mental abilities that develop slowly without necessarily changing your ability to go about your day to day activities.

There are different types of MCI.

Amnestic mild cognitive impairment is the one most associated with memory loss.

Individuals with amnestic MCI tend to have more memory problems than others in their age group. Some of the signs of MCI are:

  • Forgetting to go to appointments or events
  • Frequently losing things
  • Having challenges coming up with words than other individuals of the same age

9. Sleep Deprivation

This is not just light sleeping; you need to ensure that you are enjoying rapid eye movement sleep also known as deep sleep which plays a crucial role in memory.
