There are few scientifically proven facts about the causes of OCD. Medical researches suggested that this disorder could be caused by some biological factors, not by previous behavioral experiences or social problems of a person. Studies showed that this disorder could be related to some irregularities of nerve cells connections in certain structures of human brain, associated with a lack of serotonin.
Nevertheless, modern specialists cast doubt upon this theory, supposing that a lack of serotonin was not the cause but the reaction of human organism on OCD. Medical experiments of National Institutes of Health resulted with discovering of certain genetic mutation, affecting serotonin transporter. This mutation can probably be one of the causes of OCD, as well as certain failures on chemical level in those areas of human brain, where communication “intentions-actions” takes place (so called “Brain Lock”). Also, specialists suppose that the development of OCD is connected with the processes in the cingulated cortex and the striatum of human brain.
OCD can be treated in two different ways: medication treatment and psychological therapy. Both these types can be effective, but on the first stages it is better to consult a psychiatrist and choose a proper method of psychological therapy, which is less radical and harmful. Medicines like sertraline, fluvoxamine, paroxetine or fluoxetine, which stimulate activity of serotonin 5-HT in brain, are quite effective for decreasing occurrence and severity of OCD syndromes.
The mentioned medicines can be used along with some tricyclic antidepressants or hallucinogens. Besides, some positive effect can be received when using definite vitamins, mineral supplements and natural sugar Inositol. Unfortunately, as soon as the treatment is over, symptoms tend to appear again. That’s why it is better to continue such treatment with lower doses of medications.
