OCPD is also highly comorbid with Cluster A personality disorders,[4]
especially paranoid and schizotypal personality disorders.OCPD is also linked to hypochondriasis, with some studies estimating a rate of co-occurrence as high as 55.7%.Moreover, OCPD has been found to be very common among some medical conditions, including Parkinsons disease and the hypermobile subtype of Ehler-Danlos syndrome. The latter may be explained by the need for control that arises from musculoskeletal problems and the associated features that arise early in life, whilst the former can be explained by dysfunctions in the fronto-basal ganglia circuitry. Treatment
The best-validated treatment for OCPD is cognitive therapy (CT) or cognitive behavioral therapy (CBT), with studies showing an improvement in areas of personality impairment, and reduced levels of anxiety and depression. Group CBT is also associated with an increase in extraversion and agreeableness and reduced neuroticism. Interpersonal psychotherapy has been linked to even better results when it came to reducing depressive symptoms. Epidemiology
Estimates for the prevalence of OCPD in the general population are 3%, making it the most common personality disorder. Current evidence is inconclusive as to whether OCPD is more common in men than women, or in equal rates among sexes. It is estimated to occur in 8.7% of psychiatric outpatient settings.A study of data collected in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions looked specifically for seven personality disorders as defined by the DSM-IV. The study concluded the most prevalent personality disorder of the surveys population to be OCPD, at 7.88%.
Obsessive–compulsive personality disorder (OCPD) is a cluster C personality disorder marked by an excessive need for orderliness and neatness. Symptoms are usually present by the time a person reaches adulthood, and are visible in a variety of situations. The cause of OCPD is thought to involve a combination of genetic and environmental factors, namely problems with attachment.This is a distinct disorder from obsessive–compulsive disorder (OCD), and the relation between the two is contentious. Some studies have found high comorbidity rates between the two disorders but others have shown little comorbidity. Both disorders may share outside similarities, such as rigid and ritual-like behaviors. Attitudes toward these behaviors differ between people affected with either of the disorders: for people with OCD, these behaviors are egodystonic, unwanted and involuntary, being the product of anxiety-inducing and involuntary thoughts. On the other hand, for people with OCPD, they are egosyntonic; the person perceives them as rational and wanted, being the result of, for example, strong adherence to routines, a desire for control, or a need for perfection. OCPD is highly comorbid with other personality disorders, autism spectrum, eating disorders, anxiety, mood disorders, and substance use disorders.The disorder is the most common personality disorder in the United States, and is diagnosed twice as often in males as in females, however, there is evidence to suggest the prevalence between men and women is equal.
