Q

Q

define heterogeneity

A
  • individuals with the same diagnosis may have very different symptoms and present differently (wide variety of symptoms for each disorder)
  • DSM criteria usually require only some of the noted criteria (Major Depressive Disorder diagnosis based on 5 of 9 potential markers)

Q

What are the implications of the symptom-based classification, heterogeneity?

A
  • Makes it difficult to explain behaviours and determine the best treatments
  • diagnoses are short-hand and sometimes approximate: given range of symptoms and variation, are these two cases or individuals experiencing the same disorder? is it a subtype or an entirely different disorder?

  • similar treatments (CBT and exposure-based therapies)
21
Q

What are some differences between OCd and PTSD

A
  • obsessions and compulsions are very different experiences than flashbacks
  • ocd is not always triggered by a traumatic incident
22
Q

One such group of disorders are referred to as somatic symptom and related disorders, several diagnoses that involve concerns about one’s health

Historically, individuals who presented with mysterious symptoms (ex. unexplained paralysis or sudden blindness) were classified as having conversion disorder and deemed to have distress or internal conflict that had been “converted” into physical dysfunction

Meanwhile those who were intensely preoccupied with the possibility of being or becoming ill were said to be suffering from hypochondriasis

In DSM-5, these terms have been replaced with what new categories?

A
  • somatic symptom disorder and illness anxiety disorder
23
Q

define somatic symptom disorder (textbook)

A
  • used to describe individuals who exhibit significant anxiety and fixation on somatic (physical) symptoms, such as pain, headaches, or exhaustion
  • unlike hysteria and conversion disorder, which assumed that individuals were not in fact ill, people diagnosed with somatic symptom disorder may or may not have a diagnosed medical condition
  • what makes them mentally ill, if they have a recognized medical condition, is that their reaction to their physical symptoms is excessive and abnormal
24
Q

in other cases, individuals who do not exhibit any somatic symptoms worry excessively about what?

A
  • the possibility of becoming ill
  • this is a condition described by DSM-5 as illness anxiety disorder
25
Q

people diagnosed with illness anxiety disorder are said to be what?

A
  • “easily alarmed about personal health status” and to perform excessive health-related behaviours, such as checking for signs of illness

such individuals might read a newspaper story about someone falling ill and immediately begin to sense the symptoms themselves, conducting extensive internet searches to learn as much about the illness as possible

26
Q

review about somatic symptoms and related disorders

A
  • while people diagnosed with somatic symptom disorder and illness anxiety disorder may make excessive use of the healthcare system, the DSM notes that their concerns are rarely alleviated by visits to physicians
  • such individuals may be extra-sensitive to their bodily sensations, and the DSM suggests that they are more likely than others to report feeling side effects to medications
  • moreover, “some feel that their medical assessment and treatment have been inadequate”
  • somatic symptom disorder and illness anxiety disorder highlight the complexity of the relationship between mental and physical health. In doing so, they also encourage us to consider difficult questions. ex. who gets to determine whether concerns over a person’s health status are excessive should a clinician, who obviously has less at stake in the matter than the patient themselves, be able to determine whether anxieties about a symptom of a medically explained illness are excessive? Could such diagnose, while likely warranted much of the time, inadvertently pathologize those with medically unexplained illness simply because medical science has not yet found a cause>
27
Q

define somatic symptom disorder (lecture)

A
  • describes individuals who have anxiety and/or a fixation on somatic symptoms such as headache and pain
  • replaced the term “conversion disorder”
  • people may or may not have a diagnosis for a physical illness that is causing their symptoms
  • the diagnosis of this disorder is related to an “excessive and abnormal” psychological reaction tot he physical symptoms
28
Q

Define illness anxiety disorer

A
  • this disorder is characerised by excessive worry about the possibility of becoming ill, previously known as “hypochondriasis”
  • for both disorders, individuals may extensively and excessively utilize the healthcare system but this doe snot lessen concerns
29
Q

what are the 4 common symptom dimensions

A
  • cleanin/contamination
  • symmetry
  • forbidden/taboo thoughts
  • harm
30
Q

What is body dysmorphic disorder characterized by?

A
  • preoccupation with one or more perceived defects or flaws in physical appearance that are not observable or appear only slight to others, and by repetitive behaviours (ex. mirror checking, excessive grooming, skin picking, or reassurance seeking) or mental acts (ex. comparing one’s appearance with that of other people) in response to the appearance concerns
  • the appearance preoccupation are not better explained by concerns with body fat or weight
  • muscle dysmorphia is a form of body dysmorphic disorder that is characterized by the belief that one’s body build is to small or is insufficiently muscular
31
Q

What is hoarding disorder characterized by?

A
  • persistent difficulty discarding or parting with possessions, regardless of their actual value, as a result of a strong perceived need to save the items and to distress associated with discarding them
  • differs from normal collection

ex. symptoms result in the accumulation of a large number of possessions that contest and clutter active living areas to the extent that their intended use is substantially compromised

  • the excessive acquisition form of heading disorder, which characterized most but not all individuals with hoarding disorder, consists of excessive collecting, buying, or stealing of items that are not needed or for which there is no available space
32
Q

What is Trichotillomania (hair-pulling disorder_ characterized by?

A
  • recurrent pulling out of one’s hair resulting in hair loss, and repeating attempts to decrease or stop hair pulling
  • excoriaation (skin-picking) disorder is characterized by recurrent picking of one’s skin results in skin lesions and repeating attempts to decrease or stop skin picking.
  • these two are not triggered by obsessions or preoccupations
  • however may be preceded or accompanied by various emotion states such as anxiety or boredom
  • sensation may lead to gratification, pleasure, or a sense of relief when the hair or skin is pulled or picked
  • varying degrees of conscious awareness of the behaviour while engaging in it
33
Q

What do substance/medication-induced obsessive-compulsive and related disorder consist of?
