A lot of research has been conducted to find out the absolute cause of OCD, but none has been successful till today to come out with the exact cause of OCD. But the following reasons can surely account for this problem;

• Neurobiological problems
• Genetic problems
• Pregnancy
• Learned behaviours
• Environmental factors

What is the contribution of the biological factors in making the person suffering from OCD?

When the brain experiences some sort of chemical imbalance or has some kind of fault in the brain circuitry and the genes, the person may behave in an unnatural way.

Important information

According to the research, the person suffering from OCD problems have some different structures of the parts of the brainsbas compared to the non-sufferers.

Genetic Factors

It has been observed with the many patients of the OCD that any member of their family has once experienced this problem and because of that, it has got inherited in the patient.

Learned behaviours

Not only the genetic causes and the biological factors are responsible for making the person suffer from the OCD problem. The person can experience this problem by learning the behaviours from an OCD afflicted problem. If we take the instance of the children, we may get a better understanding of the same:

The children tend to copy what their elders are doing. So if any of the elders are suffering from ICD, then the chances are high that the children may start following the same actions repeatedly.

Chemical imbalance

Psychiatrists usually take the biochemical imbalance as the primary cause of OCD.

So how does this chemical imbalance take place?

Serotonin is a chemical that is found in the brain and is responsible for handling the following:

• Anxiety
• Memory
• Sleep

What according to the psychological theories is the main cause of OCD?

According to the research the person suffers from OCD when he has started taking negative thoughts into account. These thoughts change the behaviour of the person to deal with the situations which previously were sounding neutral. These things happen when the person has some bad experiences in life.

What does behaviour therapy have to say in this regard?

Because of the successful treatment of the patient suffering from chronic obsessional neurosis with the behaviour treatment, the psychological models are being deemed as the ideal option for the obsessions.

Behaviour therapy has also been successful which was carried out through the desensitisation for phobic avoidance.

What does Cognitive therapy have to say for OCD?

According to several cognitive theories, people with OCD are having several beliefs which are not true as far as sense is concerned. Those intrusive thoughts lead the person to suffer from OCD.

What are the other causes which are accountable for making the person suffering from OCD?

if the individual is majorly stressed with something then there are 80% chances that he may suffer from OCD. If the person does not tackle the stress, then the symptoms of stress may get worsened.
