Issues related to autonomic nervous system dysfunction?

I apologize for the inconvenience, but I would like to ask the doctor a few questions: Currently, I am experiencing symptoms of intermittent anxiety, which makes it difficult for me to concentrate.
I often change my mind and struggle to think clearly.
At times, I feel depressed to the point of feeling worthless and having suicidal thoughts; I have even attempted suicide in the past.
However, there are also times when my mood becomes excessively elevated, leading to insomnia or an urge to shop compulsively.
Additionally, I have become increasingly sensitive to changes in my external environment, such as mild smells or sounds, which can trigger anxiety, anger, or nausea (this was not the case in the past).
There was even an instance where I experienced extreme dizziness and nausea, resulting in vomiting.
The clinic doctor informed me that this is autonomic nervous system dysregulation and prescribed antidepressants to help regulate it.
However, after undergoing an examination in the neurology department, the neurologist stated that my neurological function is normal.
I returned to the clinic to discuss my condition with the doctor, who said that it cannot currently be diagnosed through instrumental testing and advised me not to focus too much on the cause of my illness.
Is this statement correct? It sounds a bit strange to me; how can treatment be provided without first identifying the cause? It seems the doctor implies that my symptoms are primarily caused by autonomic nervous system dysregulation, and that regulating the autonomic nervous system will lead to improvement.
But since the test results are normal, could there be other causes aside from the autonomic nervous system? Or is it true, as the doctor said, that this cannot be diagnosed through instruments? Is there a possibility of misdiagnosis? Should I consider seeking a second opinion from another clinic and discussing my condition with a different doctor?

Hello: The symptoms described in the text indeed align with what is commonly referred to as autonomic nervous system dysfunction.
I'm not sure if your clinic is a psychosomatic medicine clinic; generally, there is a distinction between neurology and the terminology used in clinics, which should be viewed from different perspectives, but it shouldn't reach the level of misdiagnosis.
However, based on your concerns, I personally recommend focusing on psychosomatic medicine for treatment.
Additionally, some facilities may offer a self-funded test known as "autonomic nervous system analysis," which can serve as an auxiliary reference for diagnosis.

Understanding autonomic nervous system (ANS) disorders can be quite complex, especially when symptoms overlap with various psychological and physiological conditions. The autonomic nervous system is responsible for regulating involuntary bodily functions, including heart rate, blood pressure, respiration, digestion, and sexual arousal. It is divided into the sympathetic and parasympathetic nervous systems, which work together to maintain homeostasis in the body.

Your symptoms, including anxiety, difficulty concentrating, mood swings, and heightened sensitivity to environmental stimuli, suggest a potential dysregulation of the autonomic nervous system. These symptoms can indeed be indicative of an ANS disorder, but they can also overlap with mood disorders such as anxiety and depression. The fact that you experience extreme emotional fluctuations, from feelings of worthlessness to episodes of heightened energy, may suggest a mood disorder that could coexist with ANS dysfunction.

It is important to note that diagnosing ANS disorders is not straightforward. Unlike conditions that can be easily identified through imaging or blood tests, ANS disorders often require a comprehensive evaluation that includes a detailed medical history, symptom assessment, and possibly autonomic function tests. These tests can measure how well your autonomic nervous system is functioning, but they may not always be available or conclusive.

Your concern about the doctor's statement that there is no reliance on instruments for diagnosis is valid. While it is true that many aspects of ANS function cannot be directly measured with standard diagnostic tools, there are specialized tests available, such as heart rate variability analysis, tilt table tests, and sweat tests, that can provide insights into autonomic function. If your symptoms persist and significantly impact your quality of life, it may be worthwhile to seek a second opinion from another neurologist or a specialist in autonomic disorders.

Moreover, the treatment approach suggested by your doctor—using antidepressants to help regulate the autonomic nervous system—can be effective for some patients. Antidepressants can help alleviate anxiety and depressive symptoms, which may, in turn, help stabilize autonomic function. However, it is crucial to monitor your response to medication closely and communicate any concerns or side effects to your healthcare provider.

In addition to medication, consider exploring other therapeutic options such as cognitive-behavioral therapy (CBT), mindfulness practices, or relaxation techniques. These approaches can help manage anxiety and improve emotional regulation, potentially leading to better overall functioning of the autonomic nervous system.

Lastly, if you feel that your concerns are not being adequately addressed or if you are uncomfortable with your current treatment plan, it is entirely reasonable to seek a second opinion. Finding a healthcare provider who listens to your concerns and collaborates with you on your treatment plan is essential for effective management of any health condition.

In summary, while your symptoms may suggest an autonomic nervous system disorder, they could also be related to mood disorders or other underlying issues. A thorough evaluation by a specialist, along with appropriate diagnostic tests, can help clarify the situation. It is essential to advocate for your health and seek the care that you feel is necessary for your well-being.
