Psychogenic non epileptic seizures: why is your memory so bad if this is all psychological?

An almost universal cognitive complaint in persons with PNES is that their memory is bad and it is not unusual after going through neuropsychological testing of memory (verbal, visual, etc.), that these complaints are officially confirmed.  Although we are not sure, these memory problems are probably due to more than one reason.   

The most obvious answer is that if you are clinically depressed or anxious (which co-occur in PNES at high rates) your thinking takes a hit.  A depressed or anxious person may think slower or faster, as well as having problems with sustained attention, mental efficiency and memory.  Note, if you tend to dissociate (split yourself off from consciousness), you miss things and may seem to have “poor memory.”

But there is also some newer research with imaging techniques (i.e. fMRI) in patients with post-traumatic stress disorder (PTSD) that has reported that persons with childhood sexual abuse and/or PTSD have observable differences in their brain structures.  How come?  It is known that when someone experiences a traumatic event, the body releases cortisol, neurotransmitters in the brain react, and primitive lower brain mechanisms take over.   In a child who is not yet speaking, visually may be the only way this information can be processed.  In a brain that is still forming, these processes may have a lifelong effect and change brain development. 

As a clinical psychologist, I have many times been impressed by the minute visual details patients can recall of their trauma; as if it were “seared” in the mind.  But also in everyday life, these patients seem to have better visual memory while verbal weaknesses and poor verbal memory is not unusual. 

At our center we tested 49 PNES patients with visual and verbal memory tests; those with a history of sexual abuse showed a significant strength on visual memory on the Continuous Visual Memory Test as compared to others.

So, for those who dismiss PNES as something that is “just psychological,” don’t be so hasty.  The fact that it is psychological does not mean it does not have some very real consequences.

    My son says he loses YEARS in a time line after his “Black-out” seizures. He now thinks it’s 1989… the year he graduated from H.S. Doesn’t remember his 4 children, 3 wives, or his mission to East Germany. Ive never read anything of this type of loss or his blackouts with PNES. What’s with this kind of PNES ???

      It’s been quite some time since this article but I felt I had to respond. My SO has PNES and he frequently loses years! I’ve researched this condition off and on for 9years now and had yet to find another that lost such large amounts of time! What a relief it was to read this. It made me cry. I can now tell him he’s not the only one. I wish I had to tell him, but that is something anyway. Where we live, at the time he was diagnosed, it was myself that suggested that was his problem and when he started seeing a general practicioner regularly he only heard about it and not taught about it. It’s 9 years later and he’s still receiving no help. I am the his caregiver and companion, I am at my wits end and have fallen apart so many times but yet I never give up hope! I know someday someone will say “wth?” Why hasn’t anyone helped this man?
      Thank you!

    I have been having PNES for ten years. The first eight years were under a Cardiologist and a Neurologist who performed numerous EEGs there was no diagnosis. Following a series of seizures I scored a pacemaker due to a misdiagnosis; as for eight years it hasn’t recorded any cardiac events.
    After a seizure that hospitalised me due to resultant physical injuries. More EEGs were performed and then my Neurologist referred me to another Neurologist who specialized in Epilepsy. Upon her questioning a person who witnessed my seizure, she exclaimed, this is not Epilepsy, it’s STRESS! From there it wasn’t difficult to join the dots to PNES.
    Following a series of seizures I scored a pacemaker. the onset possibly being a high achiever working in an organisation where I had difficulty respecting my peers.
    For the last 2.5 years I have not been able to work but I’m still experiencing PNES and apart from the occasional collapse, by far the greatest impact is the loss of recent memory following each attack. A little of the lost memory returns but the most of it is gone… sadly gone forever.
    I’m being treated under a psychiatrist taking 75mg of Venlafaxine daily which having reduced the dose to avoid grogginess apparently does nothing.
    An effective treatment would be able to put my life back in order, but unfortunately I’m yet to find a solution.
