According to the dictionary of psychology of the American Psychology Association, episodic amnesia is a memory loss that affects only certain important events.
In this article, I will explore what is this specific type of amnesia known as episodic amnesia, its symptoms, causes, and how it affects individuals. Let’s get started!
What is amnesia?
Before we dive into episodic amnesia, let’s first understand what amnesia is in general.
Amnesia refers to the partial or complete loss of long-term memory, which can be caused by various factors such as brain damage, psychological trauma, or medical conditions.
While some types of amnesia may affect semantic memory or procedural memory, episodic amnesia seems to primarily impact episodic memory.
What is episodic amnesia?
It’s important to mention that there aren’t many mentions of the term ‘episodic amnesia’ in scientific papers. Though the American Psychology Association refers to this condition in its dictionary, there aren’t many studies that use this denomination.
The APA says that this condition may include a temporary capacity to remember an event, followed by periods of inability to access the memory.
A term more known is episodic memory, that is the ability to recall specific events, experiences, or personal episodes that have occurred in the past. It involves the conscious recollection of details such as time, place, emotions, and associated sensory information.
When this episodic memory is severely impaired, it is referred to, commonly, as amnesia.

Symptoms
The symptoms of amnesia can vary from person to person, depending on the underlying cause and severity of the condition.
Amnesia can manifest in various ways, impacting different aspects of memory. Here are some of the key symptoms:
- Altered Recollection: You may experience alterations in your capacity to recall past occurrences or incidents that have taken place in your life.
- Challenges with Recognition: It might become increasingly difficult for you to remember familiar faces and names.
- Geographical Disorientation: You may struggle to remember locations, even ones you’ve visited before, and find it challenging to navigate your way to them.
- Event Forgetfulness: You might find yourself forgetting about future events that you’ve scheduled and intended to participate in.”
Remember, if you or someone you know is experiencing these symptoms, it’s important to seek medical advice. Amnesia can be a sign of underlying health issues that need to be addressed.
Causes
Amnesia is a condition related to old age, normally, but it goes beyond typical age-related forgetfulness. Amnesia can be caused by a variety of factors, including:
- Alzheimer’s Disease: This progressive disease affects memory, thinking, and behavior.
- Brain Aneurysms: An aneurysm in the brain can disrupt normal cognitive function, including memory.
- Brain Tumors: Both cancerous and noncancerous growths in the brain can impact memory.
- Cerebral Hypoxia: Lack of oxygen to the brain can cause memory loss.
- Epilepsy and Seizures: Especially temporal lobe epilepsy, can disrupt memory.
- Frontotemporal Dementia: This form of dementia can lead to significant memory loss.
- Head Injuries: Concussions or traumatic brain injuries (TBIs) can result in temporary or permanent memory loss.
- Degenerative Brain Diseases: Conditions like Parkinson’s disease or multiple sclerosis (MS) can cause memory problems.
- Carbon Monoxide Poisoning: Exposure to this dangerous gas can lead to memory loss.
- Heavy Metal Poisoning: Certain heavy metals, when ingested in large amounts, can affect cognitive function.
- Transient Global Amnesia: This sudden, temporary episode of memory loss isn’t understood well but is thought to be triggered by physical exertion or emotional stress.
- Wernicke-Korsakoff Syndrome: This severe vitamin B1 deficiency, often associated with long-term alcohol use disorder, can cause memory problems.
- Psychological Trauma: Severe psychological trauma, such as post-traumatic stress disorder (PTSD), can result in episodic amnesia. Traumatic experiences can disrupt the encoding and retrieval of episodic memories.
- Stroke: In some cases, a stroke can damage brain areas involved in memory formation and retrieval, leading to episodic amnesia.
- Excessive Alcohol Consumption: Chronic alcoholism can lead to a condition known as Wernicke-Korsakoff syndrome, characterized by severe episodic amnesia.

Conclusion
The term ‘episodic amnesia’ refers to a condition that significantly impacts an individual’s ability to recall personal experiences and events. Understanding the symptoms and causes of amnesia is essential for both individuals experiencing it and their loved ones.
If you or someone you know is struggling with episodic amnesia, it is crucial to seek professional help and support.
Advances in neuroscience and psychology continue to shed light on this condition, offering hope for improved diagnosis and treatment options in the future.
