Question: I had an episode about a year where I had flashing lights, shakiness, incontinence of urine, and then had a LOC. They put me in hospital and did tests, EEG, MRI, CT and nothing really showed and diagnosed it as serotonin overload. I stopped latuda. I had another episode Friday. Where the flashing lights and vision loss occurred again, got up and was very shaky laid on floor, my husband said I didn't pass out but my had some memory loss, sweaty and felt unstable. I didn't feel stable enough to get up so I crawled to the bed. Felt very weak and then fell asleep.

Brief Answer:
I would recommend as follows

Detailed Answer:

Hello,

Your symptoms are not typical of any cardiac disorders. Although the EEG has resulted normal, your symptoms raise suspicions of focal epilepsy seizures.

For this reason, I would recommend performing a prolonged EEG with sleep deprivation, or an EEG during sleep, in order to give more information on your brain function.

I would also recommend performing some other tests to investigate for possible metabolic causes that may lead to this clinical situation:

- a glucose tolerance test for glucose intolerance
- blood electrolytes for possible electrolyte imbalance
- thyroid hormone levels for possible thyroid hormone imbalance.

I would also recommend performing an ambulatory 24-48 hours ECG monitoring in order to investigate possible cardiac arrhythmia, that may trigger this clinical situation.

A Doppler ultrasound of the carotid arteries is also necessary to examine the blood flow to the brain and investigate possible vessel narrowing that may cause TIA (transient ischemic attacks), mimicking these episodes.

You should discuss with your doctor on the above tests.

Hope I have been helpful to you. Wishing you all the best.
