Abstract:

The study investigated implicit memory function in fibromyalgia syndrome (FMS) and its association with clinical parameters. Implicit memory refers to the influence of past experience on current behavior without conscious awareness of these experiences. [as opposed to explicit memory, which involves conscious recollection of past events.]

Eighteen FMS patients and 25 healthy individuals accomplished a word-stem completion task. As possible factors mediating the expected impairment, pain severity, emotional disorders, and medication were taken into account.

The patients displayed markedly reduced task performance and higher levels of depression and anxiety.

Among the clinical features, pain severity was most closely associated with performance, whereas depression, anxiety, and medication showed only a minor impact.

The study documented reduced implicit memory function in FMS. In contrast to former findings on impaired performance of FMS patients on classical memory tests, lower implicit memory function cannot be ascribed to motivational deficits. Instead, the aberrances may relate to functional inference between central nervous nociceptive activity and cognitive processing.

    thanks for telling us all what we already know – that yes we have reduced memory function – this has been known for over 10 years.

  2. IanH says:

    that the implicit memory function (which can be more emotionally loaded) is more caused by increased pain than it is from other psychological factors such as anxiety and depression. That is a helpful confirmation. This is in contradiction to studies which try to associate FM with childhood trauma.
