Because they don't think too much, they don't think high-level ideas or deep meanings, they don't question.”** **Prof. Tarhan: “A mild intrusive thought is beneficial. This should not be called an obsession, but rather a thought repetition or rumination. This is a questioning and leads people to research and confirm." ** **Prof. Tarhan stated that they perform brain mapping in resistant cases and detect connectivity disorders between certain regions of the brain, saying, "We see that there is a disorder between the decision-making region and the image processing region of these individuals' brains. We plan the treatment for these regions."** ## İçerik ![](https://cdn.uha.com.tr/content/images/nt-260330105214.png) President of Üsküdar University, Psychiatrist Prof. Nevzat Tarhan evaluated the topic of intrusive thoughts and obsessions in the 'Akla Ziyan with Nevzat Tarhan' program broadcast on EKOTÜRK. ## **Intrusive thoughts are not Just thoughts** Prof. Tarhan stated that obsessions (compulsions), known as intrusive thoughts among the public, are situations where the human brain's natural thought-producing mechanism goes out of control, and that intrusive thoughts emerge not only as thoughts but also with unwanted emotions. Prof. Tarhan said, “In such obsessions, the person does not approve of the thoughts that come to mind. They wonder, 'How does this thought come to my mind?' This situation is also called 'mental chatter.' Just as we say 'they're talking nonsense' when someone constantly speaks unnecessarily, our brain can sometimes produce unnecessary thoughts on its own. This is a result of the brain's natural function, but if it gets out of control, it becomes an intrusive thought that bothers the person.” ## **Is every intrusive thought a disease?** Prof. Tarhan underlined that not every **intrusive **thought or compulsion should be considered a disease, stating, “If the liver's function is to produce bile, the brain's function is to produce emotions and thoughts and to decide on behavior. The human brain, unlike other living beings, has the ability for abstract thought. Thanks to this ability, humans question not only the present situation but also possibilities and meanings.” ## **Yalom's four fundamental fears!** Prof. Tarhan emphasized that humans, unlike other living beings, have four fundamental fears at an existential level, and that these are even referred to as Yalom's four fundamental anxieties. He said, “If the intensity of these exceeds a certain level, they become intrusive thoughts. One of these fears is the individual's search for meaning. For example, the feeling of loneliness... The fear and anxiety of being alone is one of the four fundamental anxieties. Another fundamental anxiety is the need for freedom. The suppression of the desire for freedom can also cause deep anxieties in people. The fourth fundamental fear is the awareness of death, that is, being aware of death and facing this reality. People must learn to recognize and manage these four fundamental fears.” ## **Obsessions feed on areas where individuals make emotional investments** Prof. Nevzat Tarhan stated that obsessions (compulsions) feed on areas where individuals make emotional investments, saying, "Whatever a person invests their emotions most in, that's where the obsession enters. If someone loves their child so much that they 'adore' them, the anxiety 'something will happen to my child' begins. This anxiety turns into a delusion, and the delusion turns into an obsession." Emphasizing that obsessions can manifest in various ways, Prof. Tarhan added, "If a person invests heavily in sexual matters, obsessions can develop from there; if in religious matters, from there. In individuals who do not prioritize meaning, obsessions can be seen in different areas such as cleanliness or order." ## **Doubt obsessions are also common…** Prof. Tarhan stated that doubt obsessions are also common, saying, "A person with doubt obsession, if they see two or three people looking at something from afar, starts creating scenarios like, 'Are they talking about me?' This situation can lead to them fearing people, becoming anxious, withdrawn, and avoidant." Prof. Tarhan stated that the feeling of "uncertainty" usually underlies such obsessions, giving an example: "They lock the car door, 'Is it done or not?' and turn to check, and turn again. This is related to being unable to be sure." ## **Intrusive thoughts are a kind of "thought tic"…** Prof. Tarhan noted that intrusive thoughts (obsessions) are a kind of "thought tic," stating, "When a person with tics struggles to perform an action, they divert their attention to another subject, short-circuiting the circuit in their brain and resuming their normal movement. The same rule applies to thought management." ## **IQ level and the relationship with intrusive thoughts** Prof. Tarhan stated that intrusive thoughts are less common in individuals with low IQs, saying, “In people with an IQ below 70, there are not many intrusive thoughts. Because they don't think too much, they don't think high-level ideas or deep meanings, they don't question. For them, eating, drinking, reproducing, and some basic information they've learned meet their needs and suffice. Individuals with an IQ below 70 are not even sent to the military. They are called 'dull normal'.” ## **Intelligent people's brains produce more thoughts** Prof. Tarhan stated that there is a direct correlation between intelligence level and the number of thoughts produced, saying, "Intelligent people's brains produce more thoughts. If an average person's brain produces a thousand thoughts a day, a person with a low IQ produces 300 thoughts, while someone with an IQ over 100 produces 2,000-3,000 thoughts a day. Managing 2,000-3,000 thoughts is certainly more difficult. Therefore, it is necessary to acquire a little more skill to manage these thoughts. Intrusive thoughts and obsessions can actually occur more frequently in people with high IQs." Prof. Tarhan interpreted this situation as, "If you have intelligence, you also have responsibility. Learn to manage it," stating that individuals with high IQs may be more prone to obsessions because they have more mental activity concerning existential anxiety, producing philosophical thoughts, and finding the truth. ## **A person with a goal can say ‘no’ to wrong thoughts…** Prof. Tarhan stated that perfectionist and detail-oriented individuals are also in the risk group for obsessions, saying, “If a person has a goal and has determined their importance and priorities for that goal, and lives by planning their day, they can say 'no' to a wrong thought that comes to mind while moving towards their goal. They immediately perceive a detail related to their goal, establish a meaningful connection between events, grasp differences, take a stand, and make the right decision." ## **Instrusive thoughts cause excessive stress hormone secretion in the brain** Prof. Tarhan stated that thoughts in the human brain flow like a river, saying, "If you put a dam in front of thoughts, they will burst and overflow. Within the flow of those thoughts, one must direct them purposefully, just as a farmer or engineer approaches a river." Prof. Tarhan stated that Intrusive thoughts cause excessive stress hormone secretion and an acceleration of energy flow in the brain, saying, "If you think about something for 15 minutes that should take 5 minutes, or if you grieve at a level of 10 for something that should cause grief at a level of 1, excessive stress hormones will be secreted in your brain." ## **Lifestyle and stress management play a critical role in genetic predisposition turning into disease** Prof. Tarhan noted that genetic predisposition plays a role in psychiatric disorders such as Obsessive-Compulsive Disorder (OCD), but stressed that this does not necessarily mean the person will definitely become ill. He emphasized that lifestyle and stress management play a critical role in genetic predisposition turning into disease. Prof. Tarhan stated that serotonin and dopamine genes function differently in individuals with OCD, saying, "These individuals have a short allele, which we call the 'SS allele,' in the serotonin gene. This situation causes the brain to be unable to produce enough serotonin under stress. Although it is not a problem under normal conditions, in situations of chronic stress, this genetic algorithm does not work well, and serotonin levels drop, making the person more prone to depression." ## **Genetic predisposition also exists in OCD** Prof. Tarhan stated that there is also a genetic predisposition in OCD, and that genetic differences and stress play an important role in psychiatric diseases, just as in physical illnesses. He said, "Under stress, one person may develop schizophrenia, another OCD, and yet another may experience depression. The reason for this is these genetic differences." Prof. Tarhan stated that mild and controllable Intrusive thoughts can help individuals make correct decisions by prompting them to question and look critically. He said, "A mild Intrusive thought is beneficial. This should not be called an obsession, but rather a thought repetition or rumination. This is a questioning and leads people to research and confirm." ## **Obsessions experienced during adolescence and "post-traumatic growth"…** Prof. Tarhan stated that obsessions experienced during adolescence, when managed correctly, can have an effect that strengthens an individual's psychological defenses, increases ego strength and psychological resilience, calling this situation "post-traumatic growth." Prof. Tarhan said, "If a person manages those Intrusive thoughts, the groundless thoughts that occur when the mind is chattering, well, this becomes a stress for them, and they emerge stronger from this difficulty. Therefore, when there are stressful thoughts, which we call obsession or anxiety, we recommend walking with them instead of running away from them or fighting them. Then these thoughts become tools that serve the individual's purpose." ## **Exam anxiety and obsession** Prof. Tarhan also offered practical solutions for obsessions that arise in situations like exams, saying, "In exams, a student might get stuck on a very simple detail and fail to solve many questions they know. In such cases, we recommend putting a mark next to the question they couldn't solve and first solving the ones they know very well. Then, in the remaining time, going back and marking the first correct answer that comes to mind usually yields more successful results. Because generally, the first thought that comes to mind is correct. In this case, the obsession can even lead to the person making fewer mistakes." ## **The influence of cultural and religious factors on obsessions** Prof. Tarhan stated that the types of obsessions can vary according to cultures, time, and circumstances, and that some cultures and rigid belief systems can support religious obsessions and make individuals dysfunctional by stimulating excessive feelings of guilt. He said, "Everything is beautiful in moderation. Everything adjusted in moderation is medicine. If you exceed the dose, even the most beautiful medicine can turn into poison. In obsession too, if you think in moderation, it can lead a person to their goal." ## **Developments in OCD treatment** Prof. Tarhan stated that significant developments have been recorded in OCD treatment in recent years, adding that they perform brain mapping in resistant cases and detect connectivity disorders between certain regions of the brain. Prof. Tarhan said, "We see that there is a disorder between the decision-making region and the image processing region of these individuals' brains. We plan the treatment for these regions." He stated that they apply treatment methods such as transcranial magnetic stimulation (TMS), by provoking the relevant regions of the brain and having the patient visualize their obsessions. Prof. Tarhan added, "During this treatment, we change the receptor sensitivity in that region of the brain. Ion channels, sodium, potassium, and calcium receptors in the brain work like pumps to regulate nerve transmission and energy flow. We can affect this system with magnetic stimulation.” ## **Successful results are being achieved with modern treatment methods** Prof. Tarhan emphasized that they are achieving much more successful results with modern treatment methods compared to 15-20 years ago, stating, "An intensive treatment process is required. Usually, a few weeks of clinical treatment followed by close monitoring are important. It takes at least 6 months for the brain pathways to return to normal. If the patient adheres to the treatment discipline, the severity of the disease can drop from 100 percent to 20-30 percent within 6 months. This is an acceptable limit, and even a 60-70 percent improvement is a great success." Prof. Tarhan stated that OCD used to be one of the most challenging areas for psychiatry, but today, with methods such as DNA analysis (genotyping) and triple treatment protocols (medication, magnetic stimulation, psychotherapy), they can offer much more effective treatments. ## **Social media triggers obsessions related to physical appearance** Prof. Tarhan pointed out that social media particularly triggers obsessions related to physical appearance, concluding his words by saying, "People look at fashion magazines and models and often compare themselves to manipulated, artificial visuals. This situation gives rise to the thought, 'Why am I not like this? I should be like this.' Popular culture also feeds this situation by glorifying pleasure, success, and physical appearance. Hollywood culture manipulates people by exploiting their vulnerabilities through social media.” ## Akademik Referans DOI: [https://doi.org/10.32739/uha.id.88333](https://doi.org/10.32739/uha.id.88333) --- *Kaynak: [Üsküdar Haber Ajansı](https://uha.com.tr) — https://uha.com.tr/prof-nevzat-tarhan-a-mild-obsession-is-beneficial*
