1. Introduction

In this comprehensive exploration, we delve into the intricate realm of somatoform disorders, a category of conditions that perplex both individuals and healthcare professionals. Somatoform disorders manifest as physical symptoms without an apparent medical cause, challenging the conventional understanding of illness [1]. Despite advancements in medical science, these disorders persist, underscoring the need for a nuanced and comprehensive understanding of their nature and treatment [2]. As we embark on this journey, our primary aim is to demystify the complexities surrounding somatoform disorders, offering valuable insights that contribute to the broader comprehension of these conditions [3].

Somatoform disorders are disorders in which patients present with a myriad of clinically significant but unexplained symptoms. They are frequent more so in non-psychiatric medical consultations and the absence of an Identifiable organic cause makes clinicians underestimate their harmful consequences or challenge their validity as disease [4]. Findings suggest that somatoform disorders are linked to a diminished capacity to consciously experience and differentiate affects, and express them in an adequate or healthy way [5]. The unexplained symptoms of SDs often cause general health anxiety, frequent or recurrent and excessive preoccupation with unexplained physical symptoms, inaccurate or exaggerated beliefs about somatic symptoms, difficult encounters with the health care systems, disproportionate disability, displays of strong, often negative emotions toward the physician or office staff, unrealistic expectations and occasionally, resistance to or noncompliance with diagnostic or treatment efforts. These behaviors lead to frequent office visits, unnecessary laboratory or imaging tests or costly and potentially dangerous invasive procedures [6].

Somatoform disorders are very frequent with a worldwide prevalence of up to 40% in general practice service [7]. De Waal et al. [8] estimated a prevalence of somatoform disorders among the Dutch general practice consulting population to be 16.1% and the most common was undifferentiated somatoform disorder with a prevalence of 13.1%.

The American Psychiatry Association (APA), in 2013, introduced somatic symptom disorder (SSD) as a new diagnosis in DSM-5. The DSM-5 diagnosis also received new diagnostic criteria that radically differed from that of somatization disorder which it replaced [9]. There are three diagnostic criteria: the A-criterion requires one or more distressing or disabling somatic symptoms. The B-criterion requires disproportionate and persistent thoughts about the seriousness of one’s symptoms (cognitive dimension), high levels of anxiety about health or symptoms (affective dimension) or excessive energy or time devoted to these symptoms or health concerns (behavioral dimension). The C-criterion specifies that somatic symptoms should persist for over 6 months [9]. SSD also replaced DSM IV’s undifferentiated somatoform disorder, hypochondriasis, and the pain disorders [6]. The DSM-5 allows SSD to be diagnosed in addition to any comorbid somatic disease thereby avoiding both mind-body dualism and equating medically unexplained with psychogenic [9].

With the release of DSM-5, the diagnostic category previously known as somatoform disorders is now called somatic symptom and related disorders (SSD) [10, 11, 12]. The key feature of SSD is patient’s concern of physical symptoms that he or she attributes to a non-psychiatric disease and such patients are subjected to unnecessary testing and procedures, therefore, appropriate diagnosis is essential [10].

In mental health care settings and in psychosomatic and psychiatric consultation liaison services, patients are usually referred with a differential diagnosis of SSD in mind [12]. Valid self-report questionnaires exist to aid in screening and diagnosis for example; Patient Health Questionnaire-15 (PHQ-15) for somatic symptom burden and Whiteley Index for health anxiety [12]. Its recommended that for patients with persistent physical symptoms, consider the possibility of SSD as early as possible other than equating them to malingering, avoid repetitive, more so risky investigations that serve only to calm the patient or yourself, attend to clues from the patient indicating bodily or emotional distress beyond the current main symptom and outside the specialist field and assess the patient’s experiences, expectations, functioning, beliefs and illness behavior more so with regard to catastrophizing, body checking, avoidance and dysfunctional health utilization [12]. Other physical symptoms, anxiety and depression should be screened for and substance use plus suicidal ideations should be screened too [12]. Incase SSD is diagnosed, the health care provider is ought to decide whether it is mild, moderate or severe according to specifiers [12].

The best-suited approach in the management of SSDs is stepped care with close cooperation of primary care, a somatic specialist, and mental health care professionals operating on the basis of a bio psychosocial model of integrating somatic as well as psychosocial determinants of distress and therapeutic factors [12]. A somatic symptom disorder is considered mild when only one of the psycho-behavioral symptoms is fulfilled; moderate, when two or more of these symptoms are fulfilled; severe, when two or more of the psycho-behavioral symptoms are fulfilled, plus when there are multiple somatic complains/one very severe somatic symptom [12].

The objective of this chapter is to provide a clear and accessible pathway for comprehending and addressing somatoform disorders. By unraveling the intricacies inherent in these conditions, we hope to empower not only healthcare professionals but also individuals seeking knowledge and understanding [13]. This exploration goes beyond the clinical perspective, encompassing the psychological and social dimensions that contribute to the complexity of somatoform disorders [14].

2. Diagnostic methods for somatoform disorders

To navigate the intricacies of somatoform disorders, an essential step involves understanding the various diagnostic methods employed by healthcare professionals [15]. This section serves as a comprehensive guide, shedding light on the diverse tools, techniques, and approaches utilized to identify and classify somatoform disorders. From thorough patient interviews that delve into the psychosocial aspects to specialized diagnostic tests designed to rule out underlying medical conditions, the aim is to provide a holistic understanding of the diagnostic process [13].

By elucidating the methodologies employed by healthcare professionals, we bridge the gap between the technical intricacies of diagnosis and the diverse comprehension levels of our readership [16]. This section seeks to empower readers, allowing them to appreciate the intricacies involved in identifying somatoform disorders in clinical settings [17]. It emphasizes the collaborative nature of the diagnostic process, involving open communication and trust-building between healthcare providers and patients [18].

3. Diagnostic advances in somatoform disorders

Recent studies have contributed to the understanding and diagnosis of somatic symptom disorders (SSD). Löwe et al. [9] conducted a scoping review synthesizing evidence on SSD, emphasizing diagnostic criteria, prevalence, and associated factors. While supporting the reliability and validity of SSD diagnosis, they identified the need for further specification, particularly in psychological criteria [9]. Another study by Zou et al. [19] explored the clinical value of infrared thermography (IRT) for diagnosing persistent somatoform pain disorder (PSPD). Despite limitations, the study concluded that IRT analysis is a valuable objective method for PSPD diagnosis, offering insights into its pathogenesis [19]. These findings underscore the importance of a multidimensional diagnostic approach to enhance accuracy and effectiveness in somatoform disorder diagnosis.

4. Management approaches for somatoform disorders

4.1 Cognitive-behavioral therapy (CBT) for symptom management

Within the expansive treatment landscape for somatoform disorders, a focal point of discussion is the efficacy of cognitive-behavioral therapy (CBT) in aiding individuals to manage the array of symptoms associated with these disorders [20]. CBT is a well-established therapeutic approach that addresses the intricate interplay between thoughts, emotions, and behaviors [21]. This section endeavors to convey CBT principles in a user-friendly manner, emphasizing its practical applications in the context of somatoform disorders.

Through clear explanations, real-world case studies, and practical examples, we aim to demystify CBT, showcasing its relevance as a therapeutic approach for individuals grappling with the challenges posed by somatoform disorders [22]. The goal is to equip readers with the knowledge needed to comprehend and appreciate the role of CBT in the holistic management of these conditions, emphasizing the importance of a patient-centered and collaborative therapeutic alliance [23].

In the expansive landscape of treating somatoform disorders, a pivotal approach highlighted in this chapter is the effectiveness of cognitive-behavioral therapy (CBT). CBT stands out as a well-established therapeutic modality that has demonstrated significant success in aiding individuals to manage the array of symptoms associated with somatoform disorders [20].

CBT operates on the premise that our thoughts, feelings, and behaviors are interconnected, influencing our overall well-being. In the context of somatoform disorders, CBT becomes a powerful tool in identifying and altering maladaptive thought patterns and behaviors that contribute to the manifestation and persistence of physical symptoms [21]. By addressing distorted thought processes, individuals are equipped with coping mechanisms to navigate the complex interplay between psychological and physical experiences [24].

4.1.2 Practical applications of CBT for somatoform disorders

This chapter takes strides to explain CBT in a straightforward manner, ensuring accessibility for a diverse readership. By demystifying the theoretical underpinnings of CBT, readers gain insights into its practical applications specific to somatoform disorders [25]. Real-world examples and case studies are integrated to illustrate how CBT interventions can be tailored to address the unique challenges presented by somatoform symptoms.

CBT operates on the principle of collaborative empiricism, wherein therapists work closely with individuals to identify and challenge distorted beliefs and perceptions contributing to their physical symptoms. Through a structured and goal-oriented approach, CBT empowers individuals to recognize and modify negative thought patterns, fostering adaptive coping mechanisms [26].

4.2 Psychoeducation: empowering through understanding

An integral component emphasized in the treatment paradigm is psychoeducation. Beyond the therapeutic sessions, empowering individuals to understand the intricate relationship between emotions and physical sensations is paramount [27]. Psychoeducation serves as a cornerstone, arming patients with knowledge about the psychosomatic nature of somatoform disorders.

This chapter places special emphasis on the importance of psychoeducation in the context of somatoform disorders. By enhancing patients’ awareness of the interconnectedness between emotional states and physical symptoms, they are better equipped to navigate and comprehend their experiences [28]. Psychoeducation acts as a catalyst for self-empowerment, enabling individuals to play an active role in their healing process.

4.3 Conclusion of the treatment landscape

In conclusion, the chapter illuminates the treatment landscape for somatoform disorders, centering on the potency of cognitive-behavioral therapy and the transformative impact of psychoeducation. By equipping individuals with the tools to recognize and modify maladaptive cognitive patterns, and by fostering an understanding of the intricate link between emotions and physical sensations, the treatment paradigm presented in this chapter seeks to not only alleviate symptoms but also empower individuals on their journey toward holistic well-being [29].
