Somatic Symptom and Related Disorders
- What is is characterised by?
- Symptoms?
- Changes from DSM-IV Criteria?
Somatic Symptom and Related Disorders
- SSRD characterised by distressed physical symptoms without clear medical explanation.
- Symptoms not intentionally produced and not fully explained by medical conditions.
- Overview of SSRD’s impact and classification under DSM-5.
- Is a new diagnosis in DSM-5.
- It involves physical symptoms with excessive thoughts, emotions, or behaviours related to the symptom.
- Symptoms may or may not have a medical explanation.
- Changes from DSM-IV criteria include eliminating the need for unexplained symptoms and adding psychobehavioral features.
- Previous disorders likely Somatization Disorder, Undifferentiated Somatoform Disorder, Hypochondriasis, and Pain Disorder are eliminated.
- These changes aim to make SSD more relevant and applicable in primary care settings.
Somatic Symptoms and Related Disorders
- Aetiology?
- Epidemiology?
SSD - Aetiology
- SSD stems from heightened awareness of bodily sensations.
- Individuals interpret these sensations as signs of medical illness.
- Unclear aetiology, but risk factors include childhood neglect, sexual abuse, chaotic lifestyle, alcohol/substance abuse.
- Severe somatisation linked to axis II personality disorders like avoidant, paranoid, self-defeating, and obsessive-compulsive disorder.
- Psychosocial stressors.
Somatic Symptoms and Related Disorders
- Pathophysiology?
- Differentials?
SSD - Pathophysiology
- Pathophysiology of SSD is unclear.
- Autonomic arousal from noradrenergic compounds may cause symptoms like tachycardia, gastric hypermotility, heightened arousal, muscle tension, and pain.
- Genetic component suggested by twin studies, with 7-21% contribution from genetic factors.
- Environmental factors also play a role in SSD. Single nucleotide polymorphisms associated with somatic symptoms in some studies.
Somatic Symptoms and Related Disorders
- Prognosis?
- Complications?
SSD - Prognosis
- Longitudinal studies indicate high chronicity, with up to 90% of SSD cases lasting over 5 years.
- Therapeutic interventions show small to moderate effect sizes based on systematic reviews and meta-analyses.
- Commonly observed outcomes include chronic limitation of general function, significant psychological disability and decreased quality of life.
Somatic Symptoms and Related Disorders
- What does the DSM-5 say?
- 3 Criteria?
- 3 things to specify?
- Mild, Moderate, Severe?
In DSM-5
- Focus on distressing somatic symptoms’ impact on daily functioning in SSD.
- Emphasis on symptoms and their effects rather than absence of medical explanations.
- Changes in duration requirement for SSD diagnosis in DSM-5.
- Reduction in duration criterion for adults and children.
- Removal of specific number of symptoms requirement, focusing on severity.
Illness Anxiety Disorder
- Formerly known as?
- 6 Criteria?
- 2 things to specify - 2 types?
= Formerly “Hypochondriasis”
What is the difference between Illness Anxiety Disorder (IAD) and Somatic Symptom Disorder (SSD)?
- The distinction between Illness Anxiety Disorder (IAD) and Somatic Symptom Disorder (SSD) lies in the source of distress.
- SSD individuals are distressed about their physical complaints.
- IAD individuals are primarily distressed by their anxiety about the meaning, significance, or cause of their physical complaints, not the complaints themselves.

- Effect on the Hippocampus?
- Trauma is also a “physioneurosis”.
- This is based on the persistence of biological emergency responses.
- The fight of flight stress response does not return to baseline.
- Trauma also has a significant impact on the development and functioning of the limbic system.
6 Differential diagnoses of trauma and stressor related disorders:
- Symptoms?
- Triggers?
- Features?
- Duration of symptoms?
- Social functioning?
Management of PTSD
- Approach?
- Psychotherapy?
- Pharmacological treatment?
Approach
- Provide education about the broad range of expected reactions to traumatic situations, the natural course of the disorder, and treatment options.
- For patients with suicidal ideation or at risk of self-harm, refer to psychiatry and consider hospitalization.
- Early trauma-focused psychotherapy prevents progression to PTSD in patients with acute stress disorder.
- What are 2 behaviours that trauma may result in?
- What are the 2 aims of a consult when seeing a patient with PTSD?
- What are 9 reactions a patient may have once trauma is triggered?
- What are the 7 aims in good clinical interaction with patients with PTSD?
- What are 6 ways drs can respond to trauma reactions?
- How should trauma-informed care be delivered?
1 - Dissociation
- Dissociation is a protective defense at the time of trauma.
- It always indicates past trauma.
- It can continue to occur with even minor triggers.
- It can be very subtle.
2 - Episodes of High Arousal
- Trauma may also result in the loss of the ability to soothe and lead to episodes of high arousal.
- Lack of a secure attachment through trauma impedes the ability of the child to learn to self soothe, to settle their own distress, to be able to be alone and not panic.
Explain the dysregulation of the hypothalamic-pituitary-adrenal axis in PTSD vs. depression?
- Hypothalamic-pituitary-adrenal (HPA) axis in the physiological state, in major depression, and in post-traumatic stress disorder (PTSD).
- Left: Physiologically, further cortisol release is reduced via a negative feedback mechanism.
- Center: In patients with major depression, the HPA axis is typically hyperactive, with increased cortisol levels at reduced feedback sensitivity. A potential underlying mechanism is a decreased function or number of glucocorticoid receptors.
- Right: In patients with PTSD, cortisol levels are reduced, despite constantly elevated CRH levels. Persistently increased CRH stimulation in the pituitary gland leads to a downregulation of CRH receptors and thus to reduced ACTH production and cortisol release. Also, increased feedback sensitivity further leads to decreased ACTH production. In contrast to depression, the function or number of glucocorticoid receptors is increased.
What is a Personality Trait?
What are the Big 5 Dimensions of Personality? (OCEAN)
Personality trait: a stable, repetitive pattern of thoughts, feelings, and behaviors characteristics of a particular individual as expressed in a wide range of social and personal contexts.
The Big Five dimensions of personality
- The most widely recognized personality model that maps personality according to five distinct dimensions, namely the degree of conscientiousness, agreeableness, neuroticism, openness to experience, and extraversion expressed by an individual.
- The dimensions are equally determined by genetic and environmental factors and remain stable throughout adulthood.
- Each dimension is the sum of several factors or characteristics and should not be assessed in binary categories of presence and absence but rather as traits on a spectrum.
Personality Disorders
- Definition?
- Age of onset?
- Gender epidemiology?
- Classification as per DSM-5?
Personality disorders
- Definition: pervasive, inflexible, and maladaptive personality patterns that lead to significant distress and/or functional impairment
Epidemiology
- Age of onset: late childhood or adolescence
- Antisocial and narcissistic personality disorders are more commonly diagnosed in male individuals.
- Histrionic and borderline personality disorders are more commonly diagnosed in female individuals.
Aetiology
- Multifactorial
- Caused by a combination of hereditary (e.g., personality disorders in parents) and psychosocial factors (e.g., child neglect, abuse)
Classification:
- The DSM-5 divides personality disorders into three clusters (A, B, and C).
- For the general character of each cluster, remember WWW: Weird (A), Wild (B), Worried (C)

List 4 Factors Influencing Stress Responses?
Factors Influencing Stress Responses
1. Genetics: Some individuals may be more predisposed to developing abnormal stress responses due to genetic factors.
2. Environment: Exposure to chronic stressors, such as a high-stress job or a traumatic event, can influence how a person responds to stress.
3. Personality: Certain personality traits, such as resilience and optimism, can affect an individual’s ability to cope with stress.
4. Support System: Having a strong support system can buffer against the negative effects of stress.
