Psychogenic amnesia what are its causes types treatment and prevention methods

Psychogenic amnesia is one of the disorders that significantly affect a person's life, causing them to forget important personal events and experiences. This condition is not just ordinary forgetfulness but rather a response to a severe psychological trauma that leads the mind to block these memories from conscious awareness. In this article, we will explore all the details related to psychogenic amnesia, including its causes, types, and treatment methods, to gain a clearer understanding of the condition and learn how to manage it effectively

Psychogenic amnesia is a condition where a person is unable to recall certain periods of their life. This condition is sometimes referred to as autobiographical memory loss, which includes all the significant events a person has experienced. Psychogenic amnesia can manifest in different ways, with the five most common types being:

Localized Amnesia

This means the person cannot remember a specific period of their life. This duration can range from moments to years. Usually, these forgotten periods are linked to trauma or a distressing experience. This type of amnesia typically appears hours or days after the traumatic event and may recur multiple times throughout a person’s life.

Selective Amnesia

In this type, the person forgets specific parts of events that occurred during a certain period, rather than losing all memory of that time. Localized and selective amnesia can sometimes occur together.

Generalized Amnesia

This is a rare but severe form where the person forgets their entire history and identity. In some cases, they may even lose skills they previously knew and general knowledge about the world around them.

Systematized Amnesia

This type causes the person to lose memory related to a specific person or group of people while retaining other memories.

Continuous Amnesia

In this condition, the person is unable to form new memories, meaning they cannot remember anything that happens after the onset of amnesia.

Psychogenic amnesia is often a reaction to trauma or extreme stress, and its treatment requires psychological support and specialized therapy depending on each case.

Statistics: How Many People Suffer from Psychogenic Amnesia?

It's difficult to determine the exact number of people who suffer from psychogenic amnesia, as many cases go undetected. However, estimates suggest that around 2% of people may experience it. The prevalence is higher in women (2.6%) compared to men (around 1%).

Additionally, statistics indicate that about half of the adult population in the U.S. may experience some form of dissociative disorder at some point in their lives. This condition is more common in areas affected by wars or natural disasters, highlighting the impact of environmental factors.

What Factors Contribute to Psychogenic Amnesia?

Several factors can increase the risk of developing this condition, whether due to medical conditions or unhealthy lifestyle habits, including:

• Excessive alcohol consumption and addiction, which can impair memory.
• Taking certain medications in high doses, potentially leading to negative effects such as memory loss.
• Severe sleep disorders, which affect brain efficiency and cause neurological problems.
• Depression, which can lead to various symptoms, including memory issues.
• Experiencing a severe psychological trauma or suffering from post-traumatic stress disorder (PTSD).

Treatment usually involves psychotherapy sessions, support from family and friends, and sometimes medications if necessary.

The Difference Between Memory Loss Due to Psychological Trauma and Medical Amnesia

There is a significant difference between these two types of memory loss, including their causes, treatment approaches, and even the process of memory recovery. Here’s how they differ:

 

Psychogenic Amnesia (Due to Psychological Trauma)

• Occurs due to severe psychological stress, such as losing a loved one or experiencing a traumatic event like physical or sexual assault.
• The brain attempts to escape the trauma by forgetting as a psychological defense mechanism.
• Memory recovery can happen suddenly, within hours or months.
• The patient does not always feel anxious or stressed and may live normally without issues despite the memory loss.

Medical Amnesia (Due to Brain Injury)

• Caused by brain injuries, such as strokes, head trauma, or neurological diseases like Alzheimer’s.
• The condition results from physical damage to the brain, not just a psychological reaction.
• Memory recovery is usually gradual, taking years, and in some cases, not all memories return.
• Patients often experience anxiety and depression due to their inability to remember their past or interact normally with others.

Causes of Psychogenic Amnesia

Psychogenic amnesia is strongly linked to severe psychological trauma, particularly in individuals who have experienced distressing events either in childhood or later in life. Some key causes include:

1. Exposure to Traumatic Events

• Extreme stressors such as wars, natural disasters, violent accidents, abuse, or intense emotional trauma.
• Chronic stress and persistent anxiety affect brain function, making memory retrieval difficult as a defensive mechanism.

2. Genetic Factors

• A family history of psychogenic amnesia increases the likelihood of developing the condition, suggesting a genetic role in its occurrence.

It's important to note that psychogenic amnesia can be temporary or permanent, and an individual may experience multiple types of memory loss simultaneously.

 

Types of Psychogenic Amnesia

1. Anterograde Amnesia

• The person cannot form new memories after the traumatic event but can recall everything that happened before it.

2. Retrograde Amnesia

• The individual forgets events that occurred just before the trauma but can remember events that happened long before it.

3. Transient Global Amnesia (TGA)

• A complete but temporary loss of memory, usually resolving within 24 hours.
• The condition can last from an hour to 10 hours before memories gradually return.

4. Post-Traumatic Amnesia

• Occurs after a head injury or violent accident and is one of the most common causes of temporary memory loss.

5. Dissociative Amnesia

• Triggered by severe psychological trauma, causing the person to forget large parts of their life or even their entire identity.
• Memory may return over time, but some painful memories may never resurface.

Diagnostic Criteria According to DSM-5

According to the DSM-5, the primary reference for diagnosing mental disorders, psychogenic amnesia must meet the following criteria:

• Inability to recall important autobiographical information, especially related to a traumatic or stressful event, in a way that cannot be explained by normal forgetfulness.
• The memory loss can be:
  • Localized or selective (forgetting specific events).
  • Generalized (forgetting identity and entire life history).
• Symptoms cause significant distress or impairment in social, occupational, or other important aspects of life.
• The condition is not due to substance use, medication effects, or neurological conditions such as:
  • Stroke
  • Transient Global Amnesia (TGA)
  • Traumatic Brain Injury (TBI)
• The disorder is not better explained by other psychological conditions, such as:
  • Dissociative Identity Disorder
  • Post-Traumatic Stress Disorder (PTSD)
  • Acute Stress Disorder
  • Neurocognitive Disorders

Symptoms of Psychogenic Amnesia

Psychogenic (or dissociative) amnesia differs from other types because it is not caused by brain damage but rather by severe stress or trauma. Common symptoms include:

1. Partial or Localized Memory Loss

• The person forgets specific periods of their life, particularly those linked to a traumatic event (e.g., assault or a tragic accident).
• Can involve forgetting childhood memories or a particular phase of early adulthood.

2. Generalized Memory Loss

• A complete loss of identity-related information, such as:
  • Forgetting one's name, job, family, or friends.
  • The person may not recognize their location or even their own age.

3. Dissociative Fugue (Wandering Amnesia)

• One of the most severe forms, where a person completely loses their memory and may travel to a new place without recalling their past identity.

4. Chronic Anxiety

• Most affected individuals experience persistent anxiety, even without an obvious reason for their fear or stress.

5. Sudden Memory Recovery

• Psychogenic amnesia is often temporary, and when memories return, they do so suddenly and completely.
• Memory restoration can be triggered by a specific event or through therapy sessions.

Prevention of Psychogenic Amnesia

To reduce the risk of developing psychogenic amnesia, healthy habits that enhance memory and mental well-being can be adopted, such as:

1. Engaging in Physical Activity

• Improves blood flow to the brain, which helps in memory retention.
• Regular exercise is recommended, ideally daily or at least consistently.
• Activities like walking, swimming, and yoga help reduce stress and improve mental health.

2. Keeping the Mind Active

• Engage in mental exercises, such as:
  • Solving crossword puzzles and brain teasers.
  • Playing a musical instrument or learning a new skill.
  • Participating in social activities or volunteering to stimulate the mind.

3. Maintaining Social Interaction

• Socializing reduces the risk of depression and anxiety, which contribute to memory loss.
• Attending social gatherings and community events helps maintain mental and emotional balance.

4. Organizing and Managing Time Effectively

• Disorganization increases forgetfulness, so it’s helpful to:
  • Write important notes in a journal or digital app.
  • Set priorities and reduce distractions.
  • Use to-do lists and daily schedules to stay organized.

5. Getting Sufficient Sleep

• Sleep is essential for memory consolidation and recall.
• 7 to 9 hours of sleep per night is recommended to support cognitive functions.

6. Following a Healthy Diet

A balanced diet directly impacts brain health and memory, so it's important to consume:

• Omega-3 fatty acids (found in fatty fish like salmon and tuna).
• Antioxidants (found in fruits and vegetables).
• Vitamins and minerals such as Vitamin B12, Vitamin D, and Magnesium.
• Avoid saturated fats, processed foods, smoking, alcohol, and drugs, as they negatively impact brain function and memory.

7. Managing Chronic Conditions

Certain chronic illnesses can increase the risk of psychogenic amnesia, including:

• Depression and anxiety disorders.
• High blood pressure and high cholesterol.
• Diabetes, which affects blood vessels in the brain.
• Obesity, which reduces blood flow to the brain.
• Hearing loss, which has been linked to cognitive decline.

Following medical guidelines and effectively managing these conditions can reduce their impact on memory. Additionally, patients should ensure that medications do not impair cognitive function, as some prescription drugs may cause forgetfulness or mental confusion.

Who Treats Psychogenic (Dissociative) Amnesia?

Psychogenic amnesia is typically treated by mental health professionals, and the appropriate specialists include:

• Psychiatrist – A medical doctor specializing in diagnosing and treating mental disorders. They can prescribe medications such as antidepressants or anti-anxiety drugs if needed.
• Psychologist – A specialist in psychotherapy who does not prescribe medication. They use treatments like cognitive behavioral therapy (CBT) or talk therapy.
• CBT Therapist – Focuses on modifying thought patterns and coping mechanisms to help patients deal with trauma.
• Clinical Hypnotherapist – May assist in safely retrieving lost memories through guided hypnosis.

If the memory loss is caused by a medical condition, such as brain injury, consulting a Neurologist (a specialist in brain and nervous system disorders) may be necessary.
