Frégoli Delusion

Other Known Aliasesdelusion of doubles

Definitionmistaken belief that some person currently present in the deluded person’s environment (typically a stranger) is a familiar person in disguise.

Clinical Significance to the patient, the stranger is believed to be psychologically identical to this known person (who is not present) even though the deluded person perceives the physical appearance of the stranger as being different from the known person’s typical appearance. There are 4 subtypes:

Historythis syndrome was first published in 1927 by Courbon and Fail who describe a case of a young woman who believed she was being pursued by two Parisian actresses in disguise. They named this delusional syndrome after Leopoldo Frégoli, who was an Italian stage actor with an extraordinary ability to impersonate and mimic others on stage.

Purpose Behind Screening

  • Many of the more common conditions in psychiatry are often “silent”
    • Meaning that it can be difficult to objectively diagnosis
    • Some patient also don’t like talking about their illness with other clinical staff
  • These screening tools can be given to any patient to complete without having to talk about it out loud and then reviewed by you to see if there needs to be any further discussion
  • Some of these (GAD-7, PHQ-9) can also be used to track changes in the scores during therapy or treatment to see how well it is working

PAINE #PANCE Pearl – Psychiatry



Question

A 20yo man, with no significant past medical history, is brought in by his parents for evaluation of concerning behaviors. They state he often feels he “needs” to arrange the items in his room in a certain way and becomes very agitated if they are moved. He also must make sure that there is no dirt on his shoes before he walks in his room and is meticulous in his cleaning endeavors every day. His parents are worried about his level of functioning and ability to move out and maintain his own apartment. He denies any thoughts of self-harm, homicidal ideations, or audio-visual hallucinations. On physical examination, he seems composed, non-distracted, and answers all questions appropriately. When asked about these behaviors, he recognizes that they are a problem, but states he can’t relax and has severe anxiety unless these are taken care of.

  1. What is the most likely diagnosis based on this presentation?
  2. What criteria must be met per the DSM-V for diagnosis?


Answer

The most likely diagnosis is obsessive compulsive disorder and is defined by the DSM-V using the below criteria:

A. Presence of obsessions, compulsions, or both

  • Obsessions as defined by:
    • Recurrent and persistent thoughts, urges, or images that are experienced, at some time during the disturbance, as intrusive and unwanted, and that in most individuals cause marked anxiety or distress.
    • The individual attempts to ignore or suppress such thoughts, urges, or images, or to neutralize them with some other thought or action (ie, by performing a compulsion).
  • Compulsions as defined by:
    • Repetitive behaviors (eg, hand washing, ordering, checking) or mental acts (eg, praying, counting, repeating words silently) that the individual feels driven to perform in response to an obsession, or according to rules that must be applied rigidly.
    • The behaviors or mental acts are aimed at preventing or reducing anxiety or distress or preventing some dreaded event or situation; however, these behaviors or mental acts either are not connected in a realistic way with what they are designed to neutralize or prevent, or are clearly excessive.

B. The obsessions or compulsions are time-consuming (eg, take more than one hour per day) or cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

C. The obsessive-compulsive symptoms are not attributable to the physiological effects of a substance (eg, a drug of abuse, a medication) or another medical condition.

D. The disturbance is not better explained by the symptoms of another mental disorder.

DSM-V Specifiers

  • Patient’s degree of insight into the illness
    • With good or fair insight
      • The individual recognizes that obsessive-compulsive disorder beliefs are definitely or probably not true or that they may or may not be true.
    • With poor insight
      • The individual thinks obsessive-compulsive disorder beliefs are probably true.
    • With absent insight/delusional beliefs
      • The individual is completely convinced that obsessive-compulsive disorder beliefs are true.
  • Tic-Related – The individual has a current or past history of a tic disorder.

Charles Bonnet Syndrome

Other Known Aliasesvisual release hallucinations

Definitionsymptoms of visual hallucinations that occur in patients with visual loss

Clinical Significance these release hallucinations can be simple, non-formed images (such as lines, flashes, shapes, etc.) or the can be formed images (such as people, animals, scenes, etc.). These patients can often be missed diagnosed as psychosis or early dementia. Diagnosis is made in the absence of other psychiatric illness or other causes of hallucinations.

HistoryNamed after Charles Bonnet (1720-1793), who was a Genevan naturalist who was a lawyer by trade, but fascinated by the natural sciences. He spent the majority of career observing and studying insects, germ theory, and philosophy. He described the eponym that bears his name in 1760 in his book “Essai analytique sur les facultés de l’âme“, where he described the hallucinations of his 87yo grandfather who was nearly blind from cataracts

Münchausen Syndrome

Other Known Aliasesfactitious disorder imposed on self

Definitionintentional falsification of physical and/or mental signs and symptoms in oneself, or in another individual, for no obvious external gain or reward

Clinical SignificanceFalling under the factitious disorders section of the DSM-V 300.19 (ICD-10 – F68.10), patients deceptively misrepresent, simulate, or cause symptoms of an illness or injury in themselves, even in the absence of obvious external rewards such as financial gain, housing, or medications.

HistoryNamed after Hieronymus Karl Friedrich von Münchhausen (1720-1797), who was a German aristocrat and military veteran. He was best known for telling elaborate stories at aristocratic dinner parties where he would embellish his tales of being a soldier and huntsman. It was during these dinner parties that he met Rudolf Erich Raspe, who was a German writer, scientist, and con artist. He found these stories so alluring and entertaining that he used them (almost verbatim) in a series of publications describing these adventures of the titular character Baron von Munchausen. Münchhausen took offense to his noble name being used to entertain commoners and attempted litigious retribution against Raspe for many years to no avail. This story did not reach eponymous notoriety until 1951 when Dr. Richard Asher published an article in The Lancet entitled “Munchausen’s Syndrome” did the eponym stick.

Kübler-Ross Model

Other Known Aliases – 5 stages of grief

Definition – chronological progression of emotional states after experiencing profound personal loss

Clinical SignificanceThe five distinct phases of this model include denial, anger, bargaining, depression, and acceptance. Although widely used, it is not based on any empirical research or evidence and can be affected by cultural norms. In fact, many mental health professionals put this in the “myth” file and say that grief/loss is not a staged event, but rather a spectrum that a person can go backwards and forwards through at any point after the event.

HistoryNamed after Elisabeth Kübler-Ross (1926-2004), who was a Swiss-American psychiatrist and recieved her medical doctorate from the University of Colorado in 1963. It was during this training that she was appalled by the treatment and management of terminally ill patients and began what would be her life’s work and passion. In 1965, she accepted an instructor position at the University of Chicago Pritzker School of Medicine and began given seminars using medical students to conduct interviews with terminally ill patients. These seminars drew both appraise and criticism, as she called into question many traditionally accepted practices of psychiatry at the time. This all culminated in 1969 where she proposed her 5 stages of grief model in her book entitled On Death and Dying. In her later career, she embraced holistic medicine and spiritulism and founded a spiritual healing center called “Shanti Nilaya” in California. Dr. Kübler-Ross suffered a series of strokes in 1995, which left her paralyzed on left side, and died in a nursing home in Scottsdale, AZ in 2004.

Asperger Syndrome

Other Known AliasesHigh-functioning autism

DefinitionThis syndrome is part of the Autism Spectrum Disorder (ASD) classification in DSM-V, but still is a distinct entity in the WHO International Classification of Disease. It is characterized by persistent impairment in reciprocal social communication and social interaction with restricted, repetitive patterns of behavior, interests, or activities.

DSM-IV Diagnostic Criteria

Clinical SignificanceChildren diagnosed with Asperger syndrome, or high-functioning ASD, have varying degree of social and/or behavioral impairments. It is on the lower end of the ASD spectrum and these children often have normal to higher level of measured intelligence at school, but struggle with social interactions, following specific directions, and meeting deadlines, which then negatively impact their progression through school. Early identification by school and medical staff can mitigate these deficiencies and help these children flourish in their formative years.

HistoryNamed after Johann Friedrich Karl Asperger (1906-1980), who was an Austrian pediatrician and received his medical doctorate from the University of Vienna in 1931. He published extensively on behavioral disorders in children and termed the phrase “autistic psychopathy” in 1944 based on earlier work by Russian neurologist Grunya Sukhareva. His work garnered little contemporary acclaim and it wasn’t until Lorna Wing, an English researched, proposed the condition as Asperger’s syndrome in 1981. This caused a resurgence in translating Asperger’s work in the early 1990’s and inclusion in the DSM-IV in 1994. As a result of this increased fervor into his work, it was also discovered that Asperger was a eugenicist during the Nazi campaign, believed that “in the majority of the cases the positive aspects of autism do not outweigh the negative ones”, and even sent children from his center to the Spiegelgrund clinic, which participated in euthanasia program of the Nazi regime.

Personal Side NoteI have been struggling recently on whether to include eponyms that were named after individuals that achieved historical and medical notoriety through abhorrent means. I had originally planned NOT to give any of these individuals further recognition on the podcast, but I feel I would be doing a disservice to the patients that were affected by these individuals. As a result, I will publish this disclaimer on these episodes and a statement that this eponym will no longer be used on the blog or podcast after the ep-pain-nym segment and ask that you do the same.

Cotard’s Syndrome

 

Other Known Aliases – Cotard delusion, Walking Corpse Syndrome

 

DefinitionRare mental illness in which a person feels they are dead, do not exist, parts of them are decaying or rotting, or they have lost internal organs, blood, or extremities.

Image result for cotard's syndrome

Clinical SignificanceThe pathophysiology is not well understood and the two thoughts are that it is due to lesions or atrophy in the parietal and/or frontal lobes, or due to neural misfiring in the fusiform gyrus that is responsible for facial recognition.

The core concept of Cotard’s syndrome is a delusion of negation and classically progresses through three stages:

  • Germination Stage – symptoms of psychotic depression and hypochondria
  • Blooming Stage – full development of the syndrome and the appearance of the delusions of negation
  • Chronic Stage – severe delusions with chronic depressive symptoms

It is most common in patients with underlying schizophrenia and psychosis and patients often withdraw from society and the outside world.  Partly because of the delusions and partly due to personal neglect of appearance and hygiene.  There is no DSM-V diagnosis for Cotard’s syndrome, so it falls under the category of somatic delusions.

Image result for cotard's syndrome

History – Named after Jules Cotard (1840-1889), a Parisian neurologist, psychiatrist, and surgeon who received his medical doctorate in 1868 from the University of Paris and worked at the Hospice de la Salpétriére  under Jean Martin Charcot.  In June 1880, he read a report on “Du délire hypochondriaque dans une forme grave de la mélancolie anxieuse” where he described a case of a 43yo woman who believed she had no brain, nerves, or entrails and that she did not need food, for she was eternal and would live forever.  Emil Régis was the first to coin the eponym in 1893.  In 1889, his daughter contracted diptheria and for 15 days he refused to leave her bedside until she recovered.  Unfortunately, he contracted the same illness and succumbed to disease later that year.

Clinical SignificanceThis condition affects 4-15 in 100,000 peoples of European descent and is extremely rare in non-European lineage.  The classic manifestations of the disease include chorea, psychiatric illness, and dementia.  These symptoms begin very slow and are often missed for a period of time, but always progress to severe deterioration of neuromuscular function.  It is uncurable and treatment is directed towards support and planning of care.  Average length of survival after symptoms onset is 10-20 years

History – Named after George Huntington (1850-1916), an American physician who received his medical doctorate from Columbia University in 1871 at the age of 21.  He came from a long line of physicians dating back to 1797, when his grandfather opened the family practice in East Hampton.  He took meticulous notes on the disease that bears his name from going on house calls with his father early in his childhood, as well as reading and transcribing notes from his father and grandfather.  He only published two papers in his career, the first of which was on this disease.  He read this manuscript before the Meigs and Mason Academy of Medicine in Middleport, Ohio in 1872 (just 1 year after graduating medical school) and received such acclaim that it was published in the Medical and Surgical Reporter of Philadelphia just 2 months later.  This paper was published in the German literature later that year and his name was forever attached to this disease.  Even William Osler read and commented on this paper in 1908 saying ” In the history of medicine there are few instances in which a disease has been more accurately, more graphically, or more briefly described.”
