Ocd why is it cause

Some effective options include:. This type of psychotherapy, sometimes called CBT , can help a person change the way that they think, feel, and behave. It may involve two different treatments : exposure and response prevention ERP and cognitive therapy. Cognitive therapy starts by encouraging the person to identify and reevaluate their beliefs about the consequences of engaging or refraining from engaging in compulsive behavior.

A doctor may prescribe a higher dosage to treat OCD, compared with depression. Still, a person may not notice results for up to 3 months. It may also help people with social anxiety. Here, find more strategies for managing OCD. If a person with mild OCD does not receive treatment, the symptoms may still improve. However, without treatment, symptoms of moderate or severe OCD do not improve and may worsen.

Treatment can be effective, but it is an ongoing process. In some people, OCD symptoms reappear later in life. Intrusive thoughts are a form of obsessive-compulsive disorder.

What is obsessive-compulsive disorder? The explanation was that some children begin to exhibit OCD symptoms after a severe strep throat infection. This mechanism may explain the subgroup of children in whom OCD develops after a streptococcal infection, and worsens with recurrent infections.

However, a later study found no link between subsequent infections and exacerbation of symptoms. What we do know is that if OCD results from a strep throat infection the symptoms will start quickly, probably within one or two weeks. So it could be that PANDAS whilst not a cause for OCD, triggers symptoms in children who are already predisposed to the disorder, perhaps through genetics or other causal explanations.

Overall, genetic studies indicate some tendency towards anxiety that runs in families, although this is probably only slight. In , a meta-analytic review reported that a person with OCD is 4 times more likely to have another family member with OCD than a person who does not have the disorder.

This and other studies have raised the possibility of familial prevalence of OCD and led to a search to identify specific genetic factors that may be involved. S However, despite a proliferation of studies, and dozens of potential gene candidates suggested, researchers have so far failed to identify a consistent candidate gene responsible for OCD. It also needs to be remembered that many sufferers do not identify OCD anywhere else in their family, or even other anxiety problems. This theory could be further questioned based on speaking to identical twins where one will have OCD and the other has no anxiety problem at all.

What this suggests is that genetics may not be the only cause of OCD if at all , and that family prevalence of OCD could be learned behaviours in some cases. In summary, there is no obvious benefit to offering biological explanations for the cause of OCD, especially if such suggestions lead those who suffer to dismiss existing psychological treatment methods.

These approaches have focused on one particular neurotransmitter, serotonin. Serotonin is the chemical in the brain that sends messages between brain cells and it is thought to be involved in regulating everything from anxiety, to memory, to sleep.

Through the accidental discovery in the late sixties of the effectiveness of the serotonin active tricyclic antidepressant clomipramine, which did not substantially impact on serotonin, led to the serotonin hypothesis. Initially, it was suggested that there was a gross deficit in serotonin; when this was not actually identified, increasingly subtle abnormalities were suggested, with the evidence overall remaining implausible at best.

In more recent years some researchers have argued that the most robust evidence for the serotonin hypothesis is the specificity of serotonin reuptake inhibitors SRI and selective serotonin reuptake inhibitor SSRI medication. However, given that this effect was the observation that generated the hypothesis, it cannot reasonably be considered as evidence for it. This could mean that serotonin is an important neurotransmitter involved in the maintenance of OCD, if not a specific cause.

Overall, there is a place for SSRIs in the treatment of OCD, especially where co-morbidity is present, provided that medication remains part of informed patient choice, and combined with psychological therapy like CBT. Other research has revealed that there may be a number of other factors that could play a role in the onset of OCD, including behavioural, cognitive, and environmental factors. For example, according to the Learning Theory , OCD symptoms are a result of a person developing learned negative thoughts and behaviour patterns, towards previously neutral situations which can result from life experiences.

Research has revealed a great deal about the psychological factors that maintain OCD, which in turn has led to effective psychological treatment in the form of Cognitive Behavioural Therapy CBT. During the 50s and 60s researchers reported the successful behaviour treatment of two cases of chronic obsessional neurosis a forerunner for the Obsessive-Compulsive Disorder name , followed by a series of successful case reports.

This discovery and research heralded the application of psychological models to obsessions and the development of effective behavioural treatments.

This research later proposed that ritualistic behaviours were a form of learned avoidance. Behaviour therapy for phobias had proved successful in the treatment of phobic avoidance through desensitisation, but attempts to generalise these methods to compulsions had been unsuccessful. Researchers argued that it was necessary to tackle avoidance behaviours directly by ensuring that compulsions did not take place within or between treatment sessions.

This thinking anticipated cognitive approaches in that they emphasised the role of the expectations of harm in obsessions and the importance of invalidating these expectations during treatment, but this was subsequently regarded as peripheral to the major task of preventing compulsions. Around the same time in the early seventies other researchers developed treatment methods in which exposure to feared situations was the central feature.

These differing approaches were subsequently incorporated into a highly effective programme of behavioural treatment incorporating the principles of what we now refer to as exposure and response prevention ERP. Support for the use of this method came from a series of experiments in which it was demonstrated that, when a ritual is provoked, discomfort and the urge to ritualise spontaneously subside when no rituals compulsions take place.

These researchers elegantly specified the behavioural theory of OCD, that behavioural treatment of OCD is based on the hypothesis that obsessional thoughts have through conditioning, become associated with anxiety that has failed to extinguish. Sufferers have developed avoidance behaviours such as obsessional checking and washing , which prevent the extinction of anxiety.

This leads directly to the behavioural treatment known as ERP, in which the person is: a exposed to stimuli that provoke the obsessional response, and b helped to prevent avoidance and escape compulsive responses. An important contribution to the development of ERP was the observation that the occurrence of obsessions leads to an increase in anxiety, and that the compulsions lead to its subsequent attenuation.

When the compulsions were delayed or prevented, people with OCD experienced a spontaneous decay in anxiety and the urges to perform compulsions. Continued practice led to the extinction of anxiety. These early behavioural theories and experiments set the stage for later cognitive-behavioural theory and treatment.

Many cognitive theorists believe that individuals with OCD have faulty beliefs, and that it is their misinterpretation of intrusive thoughts that leads to OCD. According to the cognitive model of OCD , everyone experiences intrusive thoughts from time-to-time.

However, people with OCD often have an inflated sense of responsibility and misinterpret these thoughts as being very important and significant which could lead to catastrophic consequences.

The repeated misinterpretation of intrusive thoughts leads to the development of the obsessions and because the thoughts are so distressing, the individual engages in compulsive behaviour to try to resist, block, or neutralise the obsessive thoughts.

The cognitive-behavioural theory developed following a focus on the meaning attributed to internal or external events. The cognitive-behavioural theory builds on behavioural theory as it begins with an identical proposition that obsessional thinking has its origins in normal intrusive cognitions. If the appraisal is focused on harm or danger, then the emotional reaction is likely to be anxiety. Such evaluations of intrusive cognitions and consequent mood changes may become part of a mood-appraisal negative spiral but would not be expected to result in compulsive behaviour.

Cognitive-behavioural models therefore propose that normal obsessions become problematic when either their occurrence or content are interpreted as being personally meaningful and threatening, and it is this interpretation which mediates the distress caused. Thus, according to the cognitive hypothesis, researchers have hypothesised that OCD would occur if intrusive cognitions were interpreted as an indication that the person may be, may have been, or may come to be, responsible for harm or its prevention.

According to cognitive models, the interpretation of an intrusive thought results in a number of voluntary and involuntary reactions which each in their turn can have an impact on the strength of belief in the original interpretation.

Negative appraisals can therefore act as both causal and maintenance agents in OCD. Health Conditions Discover Plan Connect. Medically reviewed by Timothy J. Legg, Ph. What is OCD? What causes OCD?

Symptoms of OCD — obsessions Obsessions are usually exaggerated versions of concerns and worries that most people have at some time. Common obsessions include: fear of contamination from germs, dirt, poisons, and other physical and environmental substances fear of harm from illness, accidents or death that may occur to oneself or to others.

This may include an excessive sense of responsibility for preventing this harm intrusive thoughts and images about sex, violence, accidents and other issues excessive concern with symmetry, exactness and orderliness excessive concerns about illness, religious issues or morality needing to know and remember things. Symptoms of OCD — compulsions Compulsions can be behavioural actions or mental thoughts.

Causes of OCD The causes of OCD are not fully understood There are several theories about the causes of OCD, including: Compulsions are learned behaviours, which become repetitive and habitual when they are associated with relief from anxiety. OCD is due to genetic and hereditary factors. Chemical, structural and functional abnormalities in the brain are the cause.

Distorted beliefs reinforce and maintain symptoms associated with OCD. Cognitive behaviour therapy Cognitive behaviour therapy aims to change patterns of thinking, beliefs and behaviours that may trigger anxiety and obsessive compulsive symptoms. Anxiety management techniques for OCD Anxiety management techniques can help a person to manage their own symptoms.

OCD support groups and education Support groups allow people with OCD and their families to meet in comfort and safety, and give and receive support. Medication for OCD Some medications, especially antidepressants that affect the serotonin system, have been found to reduce the symptoms of OCD.
