EPP0015 - Cognitive Conversion Disorder (Functional Cognitive Disorder) – what´s new?
ABSTRACT
Introduction
Some patients present with significant subjective cognitive symptoms, sometimes interfering with day-to-day live, that are not compatible with any recognizable psychiatric, neurodegenerative or systemic condition. Recent studies have proposed that these patients can be diagnosed with Conversion Disorder (Subtype Cognitive), also known as Functional Cognitive Disorder (FCD). This is a relatively recent concept, that still lacks consensus.
Objectives
Review the current state of knowledge regarding prevalence, diagnosis criteria, core clinical features and proposed treatment of Functional Cognitive Disorder.
Methods
Bibliographic review of the literature published in English in the last 5 years, in the databases Pubmed, PsycINFO and Cochrane. The keywords used were: Functional Cognitive Disorder; Cognition; Conversion Disorder. A review of the titles and abstracts of the resulting articles was made, and selected according to their relevance to the study.
Results
Ten articles related to prevalence, diagnosis, clinical associations and treatment of Functional Cognitive Disorder were selected, of which two were systematic reviews, three descriptive studies, three cross sectional clinical studies of memory clinics attendants, one cohort prospective study and one article was a case series report.
Conclusions
The prevalence of FCD is estimated between 11.6% and 56% of patients presenting to memory clinics. However, the prevalence of FCD is hindered by the lack of consensus regarding its definition. Recently, Ball et al proposed a definition in line with the DSM-5 definition of Conversion Disorder with emphasis on positive criteria with the identification of positive evidence of internal inconsistency. Treatment discussion is still limited, and the approach is similar to other conversion disorders.
EPP0618 - Transcranial Magnetic Stimulation and Eating Disorders, any efficacy?
ABSTRACT
Introduction
Eating Disorders (ED) tend to evolve chronically, with resistance to different therapeutic strategies. Chronicity is associated with high mortality rates, so it is necessary to study new therapeutic strategies. Transcranial Magnetic Stimulation (TMS) is a non-invasive, safe treatment method, whose application has been studied in several pathologies.
Objectives
Determine the therapeutic potential of Transcranial Magnetic Stimulation in the treatment of Eating Disorders.
Methods
Bibliographic review of the literature published in English in the last 10 years, in the databases Pubmed, PsycINFO and Cochrane. The keywords used were: TMS, Transcranial Magnetic Stimulation, Eating Disorder, Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder. A review of the titles and abstracts of the resulting articles was made, and selected according to their relevance to the study.
Results
Eighteen articles related to the treatment of ED with TMS were selected ,either as primary or secondary outcome, of which six were review articles, ten were randomized controlled trials (RCT), one article was an oral communication and another article was a case report. Three RCTs showed improvement in bulimia nervosa, specifically in symptoms of “food craving”. Four RCT and one case report showed improvement in the symptoms of anorexia nervosa, one RCT showed no improvement in anorexia nervosa.
Conclusions
TMS appears to have some therapeutic potential for the treatment of ED, particularly in reducing food craving, despite some contradictory results. This work reinforces the need for more robust studies to evaluate the effectiveness of TMS, preferably randomized, with a longer follow-up and a cost-benefit analysis.
