what is brain fog

Brain fog is a term used to describe a range of symptoms that can affect a person's ability to think, including confusion, forgetfulness, and a lack of focus and mental clarity. It is not a medical condition but a symptom of other medical conditions such as stress, lack of sleep, hormonal changes, and poor diet. Brain fog can also be a symptom of long COVID, depression, anxiety, or stress. It can interfere with work or school, but it does not have to be a permanent fixture in one's life. Treatment for the underlying condition causing brain fog can help alleviate the symptoms.
