What it is

A group of disorders defined by recurrent, intense sexually arousing fantasies, urges or behaviours involving atypical objects, situations or targets, lasting at least 6 months, that either cause distress or impairment or have been acted on with non-consenting people. Having an unusual sexual interest (a paraphilia) is not by itself a disorder.

Who gets it

Exact prevalence is unknown because of underreporting. Most people diagnosed are men, and onset is usually around puberty or early adulthood. Several paraphilias often coexist in the same person. Paraphilic disorders that involve non-consenting people overlap with sexual violence, a serious public health problem in Colombia, especially against children and adolescents.

Causes

Unclear; probably an interaction of neurodevelopmental, psychological and social factors
Early conditioning of sexual arousal to atypical stimuli
Altered brain function in some cases (for example in pedophilic disorder)
New-onset disinhibited sexual behaviour may result from frontal or temporal brain lesions

Risk factors

Male sex
History of childhood sexual abuse or adversity
Coexisting personality disorders, substance use, ADHD or mood disorders
Hypersexuality and social isolation

Pathophysiology

The mechanism is not well understood. Sexual arousal depends on hypothalamic and limbic circuits under hormonal influence (testosterone), while the prefrontal cortex inhibits urges. In paraphilic disorders the arousal pattern becomes fixed on atypical targets, and weak inhibitory control or impulsivity increases the chance of acting on it. This is the rationale for treatments that lower testosterone or reduce sexual drive.

Classification

Courtship disorders: voyeuristic, exhibitionistic and frotteuristic disorders
Algolagnic disorders: sexual masochism and sexual sadism disorders
Anomalous target preferences: pedophilic, fetishistic and transvestic disorders
Other specified paraphilic disorders

Symptoms and signs

Recurrent intense fantasies, urges or behaviours focused on the atypical target for at least 6 months
Distress, guilt or impairment in relationships and work
Acting on the urges with non-consenting people (exposing, watching, touching)
Pedophilic disorder: urges involving prepubertal children, in a person at least 16 years old and at least 5 years older than the child
Coexisting depression, anxiety or substance use

Diagnosis

Clinical: Clinical diagnosis by a mental health professional through a detailed, non-judgemental sexual history and DSM-5-TR criteria (at least 6 months plus distress, impairment or acting on non-consenting people). Assess risk to others, comorbidity and legal duties. Health staff must follow mandatory reporting rules when a child is at risk.
Tests: No test diagnoses it. Before medicines that lower testosterone: baseline testosterone and other hormones, liver function and bone health assessment.
Imaging: Brain MRI when behaviour begins late in life or there are neurological signs, to look for frontal or temporal lesions or dementia.

Differential diagnosis

Paraphilic interests without distress, impairment or harm (not a disorder)
Consensual sexual practices between adults
Manic episode with hypersexuality
Frontotemporal dementia or other brain lesions causing disinhibition
Antisocial personality disorder or substance intoxication
Obsessive-compulsive disorder with unwanted sexual thoughts (the thoughts are distressing, not arousing)

Goal of treatment

Prevent harm to others and reoffending, reduce distress and the intensity of urges, and treat coexisting disorders.

Treatment

Conservative: Cognitive behavioural therapy focused on relapse prevention, control of urges and empathy; group therapy
Conservative: Treatment of coexisting depression, substance use and ADHD
Medical: SSRIs for mild cases or to reduce sexual preoccupation
Medical: Testosterone-lowering medicines (antiandrogens or GnRH analogues) for high-risk cases, with consent and specialist supervision
Follow-up: Long-term follow-up of risk, adherence and adverse effects such as bone loss

Complications

Sexual abuse of children and other victims
Legal consequences and imprisonment
Relationship breakdown, isolation and depression
Bone loss and metabolic effects of testosterone-lowering treatment

Prognosis

Usually chronic, although the intensity of urges often declines with age. Combined psychotherapy and medicine reduce urges and reoffending in many treated patients; the outlook is worse with antisocial traits and substance use.

Prevention

Early help for people who recognise unwanted urges before any offence
Protection of children and prevention of child sexual abuse

What distinguishes a paraphilic disorder from a paraphilia?

The disorder causes distress or impairment, or has been acted on with non-consenting people; an unusual interest alone is not a disorder.

What is the minimum duration of symptoms for a paraphilic disorder?

At least 6 months.

For pedophilic disorder, what age criteria does DSM-5-TR set for the person?

At least 16 years old and at least 5 years older than the prepubertal child.

Which medicine classes reduce sexual drive in high-risk paraphilic disorders?

Antiandrogens and GnRH analogues that lower testosterone; SSRIs in milder cases.
