Severely Deficient Autobiographical Memory
If you’ve recently discovered the term SDAM (Severely Deficient Autobiographical Memory), you may finally have an explanation for something you’ve experienced throughout your life.
Many people with SDAM describe knowing that events happened, but struggling to mentally relive them. Rather than replaying memories as vivid experiences, they remember them more as facts than as personal recollections.
Although SDAM is still being researched, many people find that simply understanding how their mind works can be reassuring.
The first thing to understand is that SDAM is not the same as aphantasia.
Some people have both.
Many people have only one.

Ask a Question
What Is SDAM?
SDAM stands for Severely Deficient Autobiographical Memory.
People with SDAM may find it difficult to mentally revisit experiences from their own lives.
For example, they may know:
- They went on holiday.
- They attended a particular school.
- They got married.
- They met someone important.
- They passed an exam.
However, they may struggle to mentally re-experience those events in the way many other people can.
That doesn’t mean the memories are gone.
It means the experience of mentally reliving them appears to be different.
SDAM Is Not the Same as Aphantasia
This is one of the biggest misconceptions.
Although SDAM and aphantasia sometimes occur together, they are different.
Aphantasia primarily affects voluntary mental imagery.
People with aphantasia usually cannot create mental pictures.
Many still remember their lives extremely well.
SDAM primarily affects autobiographical memory.
People with SDAM may know what happened but find it difficult to mentally relive personal experiences.
Some people have:
- Aphantasia only.
- SDAM only.
- Both conditions.
- Neither condition.
One condition does not automatically mean you have the other.
Does SDAM Mean You Have a Poor Memory?
Not necessarily.
Memory is made up of many different systems.
People with SDAM often have perfectly good:
- General knowledge
- Learning ability
- Language skills
- Professional expertise
- Practical skills
- Problem-solving abilities
The difference lies mainly in the ability to mentally revisit personal experiences.
Can Hypnotherapy Help with SDAM?
At present, there is no reliable scientific evidence that hypnotherapy or NLP can restore autobiographical memory or enable someone to mentally relive experiences if they naturally cannot.
However, therapy may still be extremely helpful.
Many people benefit from:
- Better understanding how their own mind works.
- Reducing frustration or self-doubt.
- Improving confidence.
- Managing anxiety.
- Developing personalised memory strategies.
- Learning to work with their strengths rather than focusing on perceived weaknesses.
- Improving emotional wellbeing.
For many people, the goal is not to become someone else.
The goal is to understand and make the very best use of the mind they already have.
NLP and Different Ways of Thinking
Neuro-Linguistic Programming (NLP) recognises that people process information differently.
Some people naturally think through:
- Pictures
- Inner speech
- Feelings
- Sounds
- Concepts
- Intuition
- A combination of several of these
Understanding your preferred way of processing information can often make learning, communication and personal development easier.
Working With Your Mind Instead of Against It
Many people spend years believing something is wrong with them.
Often, nothing is wrong at all.
Their brain simply processes information differently.
Understanding that difference can reduce years of unnecessary frustration.
Whether you have SDAM, aphantasia, anendophasia, ADHD, or simply a unique way of thinking, therapy can help you develop strategies that work with your mind—not against it.
