Overview

Paraphilias are characterized by severe deviant sexual desire resulting in actions that may cause significant impairment in functioning as well as distress. Paraphilic behavior may occur intermittently. Some individuals have this condition consistently for their entire life. To begin with paraphilia occurs in the form of a fantasy and at a later age, the paraphilic behavior starts. imely treatment is important to prevent sexual offenses like pedophilia or serial rapes. Patients may have more than one type of paraphilia and therefore, it is essential to evaluate them thoroughly to facilitate optimum management.

Historical Perspective

  • From biblical times, human societies all across the world, have placed restrictions over many types of sexual behaviors. The level of acceptability is based on cultural variations across the globe.
  • There is controversy in what should be called sexual deviation, mainly based on various factors like the degree of consent, age of the involved individuals, degree of distress caused, location of sexual behavior, degree of unacceptable by others, etc. [1]
  • Marquis de Sade (1740-1814) gave the term sadism. He was placed in a lunatic asylum multiple times and ultimately, he died there. His mental instability, is considered to heve resulted in his pattern of sexual behavior . [1]
  • The term masochism comes from Baron Leopold von Sacher Masoch (1835-1895), who was of European origin.[1]
  • At the end of the nineteenth century, sexual deviance was started to be considered a medical condition, with the publication of Psychopathia Sexualis. [1]

Classification

  • Earlier the non-reproductive sexual behaviors were considered pathological and criminalized. However, over years the boundaries of pathology has been defined to the absence of sexual consent. [2]
  • The inclusion of pathological classification of paraphilias in the DSM and ICD has been criticized for a long time. It is based on the thin line of difference between something that is a normal variation or just unusual, and something that is pathological.
  • According to DSM-III, a patient may have more than one paraphilias but the extent of the multiplicity was not described until later editions.[3]
  • Till DSM-IV-TR, the diagnostic category of paraphilia was scrutinized for logic, clarity, and consistency. It was criticized for the fulfillment of a clear-cut mental illness.[4]
  • There were proposals to remove paraphilias as a diagnostic category from DSM-5. Some considered the concept of paraphilic disorder as more ideological instead of scientific. [5][6]
  • Despite the on-going controversies, in DSM-5, the paraphilias have been assigned a separate chapter and are termed Paraphilic disorders. [7]
  • It has been found that DSM-5 diagnostic criteria for paraphilias can increase the false-positive diagnoses and attaining this diagnosis can produce many legal consequences. [8]
  • ICD-10 does not comprise a clear-cut definition of paraphilia. It refers to paraphilia as disorders of sexual preference. [9][10]

Pathophysiology

Mononamine Hypothesis

  • Norepinephrine, serotonin, and dopamine are the monoamines involved in the physiology of sexual behavior.[11]
  • Side effects of certain medications like antidepressants, and neuroleptics show that the alteration of monoamine levels can adversely affect sexuality.[11]
  • These neurotransmitters also modulate the impulsivity, anxiety, depression,and antisocial behavior. Disturbance of these neurotransmitters may cause these conditions in paraphilia patients. [11]
  • The medications that act by increasing the serotonergic function have been found to suppress the paraphilic behavior. [12]

Role of Testosterone

The antisocial traits, and sexual behavior have been noticed to be affected by sex-steroid associated genetic influence. This is evident by the clear relationship between testosterone and paraphilia as well as the positive response seen in thses patients with the antiandrogen therapy.[13]

Differential Diagnosis

It is important to differentiate paraphilias from other disorders like-[14]

  • Impulse disorder not otherwise specified (NOS)
  • Bipolar affective disorder
  • Cyclothymic disorder
  • Substance-induced anxiety disorder
  • Dissociative disorder
  • Delusional disorder (erotomania)
  • Gender identity disorder
  • Obsessive-compulsive disorder
  • Cognitive disorders like dementia
  • Delirium

Epidemiology and Demographics

The actual prevalence of Paraphilic disorders is difficult to estimate because of existence of the nonclinical subjects.[15]

Age

  • Although discrepancies in studies exist, on an average no specific age group has been predisposed to develop Paraphilia.
  • Mostly paraphilias begin in childhood and is manifested in adolescence or later. [16]

Gender

  • The paraphilic behavior is seen mostly in men. However, there are studies which show no prominent gender-differences.[10][15][17]

Race

There is no racial predilection to Paraphilias.

Risk Factors

  • Noxious child-rearing experiences, non-sexual and sexual both[16]

Screening

Natural History, Complications, and Prognosis

Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%.

Comorbidity

Various comorbid conditions exist with paraphilias like-[10]

  • Depression
  • Generalized Anxiety disorder
  • Substance abuse
  • Erotomania
  • Suicidality

Diagnosis

Treatment

  • A treatment plan comprising of psychotherapy, and/or pharmacotherapy is usually needed to suppress the paraphiliac fantasies and behaviors.
  • The treatment depends on the severity of paraphiliac sexual fantasies as well as the risk of sexual violence. [18]
  • Very severe condition may lead to sexual offenses, like rape and it is necessary to manage such patients aggressively with hormonal intervention.[18]
