Hello! My name is Carolina , i m 29 years old, I m a healthy person, 1.70 and now my weight is 65kg. take vitamins, eat healthy, drink more than 2 liter of water every day, I don t train too much but I walk long trips instead. The only thing I ve been treated is that I have iron deficiency, nothing serious.This is not a question of urgency. But I wonder if this can be normal or it should be treated.There have been occasions (3 times actually) when I couldn t remember the word headache even in spanish, and this is my native language, or remember something like my age, but I have a very good memory. Few occasions I get a headache and i lose the vision in one eye, but I just have to sleep and then it goes away. Also it has happened to me few times that I m sleeping and awake but I can not wake up and after few seconds I can open my eyes and wake up, but it s a scary feeling.Thanks and greetings.

Hello Chat Doctor.  Too much frequent or recurrent memory loss patches either in short or long run needs a work up only then. Inability to get out of bed along with no energy is called apoplexy and its treatment is available.  (sodium oxalate, antidepressants,SSRI). Third problem you have mentioned can be a part of same spectrum of disease, but a workup is mandatory for root cause as it's highly debilitating to lose vision .get your carotid Doppler study, echocardiography with bubble study and an MRI brain, if advised by your neurologist.  Hope I have answered your query. Let me know if I can assist you further. Take Disregards.
