For the past year I have had what I can only assume is brain fog. I have significant trouble processing information, reaching conclusions, thinking abstractly, and recently reading. This has caused me to become apathetic and depressed. I cannot do my homework, and have problems remembering things. I miss extremely obvious things, such as jokes and do not pick up on many things anymore. I literaly feel that I have a fog in my head, and feel like I am behind the world looking at it, with a fog in front of my eyes. I used to be fatigued as well, however I started taking B vitamins and they helped a bit. I took anti-depressants for a while, however while my mood improved the brain fog did not go away. I have come up with several ideas as to what this may be: b-vitamin deficiency, hypoglycemia, diabetes, potassium deficiency, candida overgrowth. I was hoping that someone would be able to provide an idea on what they think this may be. I have been to a neurologist, and gotten an EEG and MRI which were normal. I am taking a blood test soon. I cannot think the way I used to, and find it hard to compete in college. This has impacted my life significantly, and I hope that someone will answer accordingly.
