Neurological Symptoms: When to Seek Further Testing - Neurology

More Info

---

Hello! It sounds like you've been experiencing some distressing neurological symptoms, and I appreciate you reaching out for guidance. Based on your description, it seems you have had a series of concerning episodes, including dizziness, a sensation of near-death, and feelings of floating while walking. These symptoms can indeed be alarming and warrant further investigation, especially since they have persisted despite previous evaluations.


Understanding Your Symptoms
1. Dizziness and Near-Death Sensation: The sudden onset of dizziness, especially if accompanied by feelings of impending doom or near-death experiences, can be indicative of several underlying issues. These could range from anxiety and panic attacks to more serious neurological conditions. The fact that you were evaluated in the emergency department and underwent various tests (EEG, auditory evoked potentials, echocardiogram, X-ray, ECG, and lower limb nerve conduction studies) without any abnormalities is reassuring but does not completely rule out all potential causes.

2. Floating Sensation: The sensation of floating while walking, which you describe as intermittent and uncomfortable, can be linked to several factors. It may be related to vestibular dysfunction, which affects balance and spatial orientation, or it could be a manifestation of anxiety or a dissociative episode.

When to Seek Further Testing
Given your ongoing symptoms and the fact that you are currently on serotonin medication, it is essential to consider the following:
- Neurological Evaluation: Since you have already undergone some neurological tests, it may be beneficial to consult a neurologist for a comprehensive evaluation. They may recommend additional tests such as MRI or CT scans of the brain to rule out any structural abnormalities or lesions that could be contributing to your symptoms.

- Autonomic Nervous System Assessment: If your symptoms are suspected to be related to autonomic dysfunction, tests such as a tilt table test or heart rate variability analysis may be helpful. These tests can assess how your body regulates blood pressure and heart rate, which can be affected in conditions like dysautonomia.

- Psychiatric Evaluation: Since anxiety can manifest with physical symptoms, it might be worthwhile to have a psychiatric evaluation if you haven't already. Cognitive-behavioral therapy (CBT) or other therapeutic interventions may help manage anxiety symptoms, which could, in turn, alleviate some of the physical sensations you are experiencing.


Recommendations
1. Follow-Up with a Neurologist: Schedule an appointment with a neurologist to discuss your symptoms in detail and consider further imaging or testing as needed.

2. Monitor Symptoms: Keep a diary of your symptoms, noting when they occur, their duration, and any potential triggers. This information can be invaluable for your healthcare provider.

3. Consider Therapy: If anxiety is a significant component of your experience, consider seeking therapy or counseling. Techniques such as mindfulness and relaxation exercises can also be beneficial.

4. Lifestyle Modifications: Ensure you are maintaining a healthy lifestyle, including regular exercise, a balanced diet, and adequate sleep, as these can significantly impact both physical and mental health.

5. Stay Informed: Continue to educate yourself about your symptoms and potential conditions, but be cautious of self-diagnosing. Always consult with healthcare professionals for accurate assessments.

In conclusion, while your previous tests have returned normal results, your ongoing symptoms warrant further investigation. A multidisciplinary approach involving both neurological and psychological evaluations may provide the best pathway to understanding and alleviating your symptoms. Please take care, and I hope you find relief soon!
