Brain Fog
Brain fog is the term used by hepatitis C patients to describe a mental condition when it is difficult for them to be alert and think well. They feel like their mind is shrouded in fog. It can be associated with other cognitive symptoms such as difficulty in concentrating and short-term memory loss.
Not every affected patient will have brain fog, and those who get usually have a wide range of experiences. You should consult your medical provider in any of these symptoms, so other causes of cognitive decline can be ruled out. Make sure to let you physician know if you have already diagnosed hepatitis C or other liver disease infection, taking some sort of medications, supplements, over-the-counter drugs, or recreational substances.
