Abstract

While amnesia and other cognitive disturbances are usually caused by structural brain damage, there are a few instances in which environmental stress may induce neuronal death in memory-sensitive brain regions such as the hippocampus. Here we report on a patient who, after a single brief exposure to an event reminding him of a similar stressful event from his childhood, deteriorated immediately and persistently without manifesting structural, but manifesting functional, brain damage as measured by position emission tomography. This patient probably represents the first case in which a direct relation between a single psychic event and the occurrence of brain malfunctioning in cognition is documented by dynamic neuroimaging methods. Psychic shock may cause lasting reductions in brain metabolism with the consequence of severe intellectual malfunctioning.

      Nevertheless, a number of patients fail to recover. Patient A.M.N. [2] developed amnesia after discovering a fire, yet did not recover despite remembering a traumatic childhood incident. However, the fact that some patients recover suggests there may be a ‘blocking’ of access to past memories, probably caused by a disturbance of control phenomena, although the underlying mechanism remains unknown.

      However, this suggests that the human brain has in some cases the ability for superior memory. Furthermore, cases of patients apparently experiencing involuntary resurgence of specific life periods have regularly been reported in retrograde, dissociative or transient global amnesia (Lucchelli et al., 1995; Kapur, 1996; Markowitsch et al., 1998; Laurent et al., 2012) or after removal of a tumour (Faber and Johnson, 2003). Though lacking a suitable review of the validity of these cases, they help maintain the idea that human memory may store much more of personal experiences than is usually believed.

      In patients with dissociative (conversion) amnesia heart rate variability is lower than in healthy participants (Tramoni et al., 2009; van der Kruijs et al., 2014). Furthermore, patients with dissociative amnesia frequently show signs of depression and alexithymia (Markowitsch et al., 1998, 1999c, 2000b; Maldano and Spiegel, 2008; Moriguchi et al., 2009; Staniloiu et al., 2010). All this impairs theory of mind functions and foresight, and reduces the patient to an extended noetic present (Suddendorf et al., 2009) with resignation and lack of concern.
