We all forget things in our daily lives, don't we? Sometimes it's where our house keys are, someone's name, or something on our shopping list. But this isn't just about simple forgetfulness. Imagine a serious condition where you forget important events in your life, sometimes even who you are. This is what we medically call amnesia.
What exactly is Amnesia?
Simply put, amnesia is a serious loss of memory. It can be a symptom of another illness, or it can occur as a standalone condition.
There's a big difference between normal forgetfulness and a condition called amnesia. Imagine you forgot the date of your friend's wedding. That's normal. But if you can't remember whether you went to the wedding or who that friend was, that could be a serious condition called amnesia. It's the complete loss of important events, information, and experiences from your life.
Are there main types of amnesia?
Yes, amnesia can be divided into several main types. Each type is different from the other. Let's take a look at what they are.
| Type of amnesia | A simple explanation |
|---|---|
| Retrograde amnesia | This is when you lose your memories of the past. That is, you don't remember things that happened before this condition occurred. But you can form new memories. |
| Anterograde amnesia | What happens here is that you can't form new memories. That is, you won't remember anything else after this condition occurs. But old memories may still be there. |
| Post-traumatic amnesia | Memory loss that occurs after an accident, especially a head injury. This can be a combination of both types mentioned above. |
| Transient global amnesia | This is a very short-lived state, usually less than 24 hours. During this time, old memories are lost, as well as the formation of new ones. But after a while, things return to normal. |
| Infantile amnesia | This is something that we all have. We don't remember things that happened when we were very young, that is, when we were babies. That's why it's called this. It's not a medical condition. |
| Dissociative amnesia | This is caused by a psychological cause. Due to unbearable psychological stress, such as severe trauma or abuse, the brain erases memories related to that event as a protective mechanism. |
What symptoms does someone with amnesia show?
Symptoms of amnesia can vary depending on the type. Common symptoms include:
- Changes in your ability to remember events or things that happened to you.
- Difficulty remembering people's names and faces .
- Losing memory of places and routes to them.
- Forgetting about upcoming events you planned to attend.
Filling in the gaps in memory (Confabulation)
This is also a characteristic of amnesia. What happens here is that your brain automatically creates false information or stories to fill in the gaps in your memory. For example, you may remember a recent event as happening on a different day, or you may completely misremember the details of a past event.
The important thing is that the person who tells false memories like this is not intentionally lying. They actually believe that the memory is correct. It's just a glitch in the brain.
What are the causes of memory loss?
There are many possible causes of amnesia. Let's divide them into two main categories: neurological causes and psychological causes.
| Main causes of amnesia | |
|---|---|
| Neurological Causes | |
|
|
| Psychological Causes | |
Memory loss can also occur due to traumatic events, such as severe trauma or abuse. This is especially common with conditions like dissociative disorders and post-traumatic stress disorder (PTSD) . Experts believe that this temporary erasure of memories is a protective mechanism that the brain uses to protect itself from unbearable emotional pain. | |
How does a doctor diagnose this condition?
When you go to see a doctor, he or she will try to diagnose the condition by asking you questions about yourself, your life, recent events, and your symptoms. In addition, they may perform various tests to find the exact cause.
- Physical and neurological exam .
- Special tests on memory and mental functioning (Neuropsychological assessment).
- Brain imaging tests, such as CT scans (Computed tomography scans) or MRI scans (Magnetic resonance imaging scans) .
- An EEG (Electroencephalogram) test that looks at the electrical activity of the brain.
- Blood tests to check for things like infections and vitamin deficiencies.
- Sometimes a spinal tap may be done to check the fluid in the brain.
Is there a treatment for this? Can it be cured?
To be honest, there is no specific cure or treatment for amnesia. The best treatment is to treat the underlying condition that caused the memory loss. For example, if it is an infection, it is treated. If it is a vitamin deficiency, it is supplemented.
In most cases, once the underlying cause is treated, the brain will recover on its own and memory will gradually begin to return.
Additionally, treatments such as cognitive rehabilitation and occupational therapy teach the skills and strategies needed to cope with the difficulties caused by memory loss. This provides great relief to both the patient and their caregivers.
When should we seek medical advice?
When memory loss occurs gradually, you may not even realize it. Often, a family member or friend is the first to notice the change. If you have self-doubt, never be ashamed to ask for help.
Situations when you need to go to the hospital urgently
Sudden memory loss is always a medical emergency. Whether there is an obvious cause or not, the safest thing to do is to see a doctor immediately.
Especially after a head injury, such as a fall, if you do not lose consciousness but have no memory of the event, it could be a sign of a traumatic brain injury (concussion or TBI) . In such a case , go to the nearest hospital's Emergency Department (ETU) immediately. It is not advisable to delay this.
Can we prevent this situation from occurring?
While we can prevent some causes of amnesia, not everything is in our control. However, there are some things we can do to reduce our risk:
- Wear safety equipment: Avoid possible head injuries. For example, if you are riding a bicycle or motorcycle, be sure to wear a helmet.
- Eat a balanced diet: Provide the nutrients needed for a healthy brain.
- Sleep well, relax, and manage stress.
- Maintain a healthy weight.
- Don't ignore ear or eye infections: These infections can sometimes spread to the brain.
- Control your other medical conditions, such as diabetes and high blood pressure.
- Keep your brain active: read books, solve puzzles.
- Maintain social connections: Talking to others is a good exercise for the brain.
- Avoid using tobacco products.
