Hi,
Brain fog and poor concentration are quite common symptoms and can occur due to several reasons, such as poor sleep, stress or anxiety, excessive screen time,
vitamin deficiencies (especially iron or
vitamin B12),
thyroid problems, or other medical conditions.
Since you've been experiencing these symptoms, it's important to understand whether they're affecting your daily activities, and if you have any other symptoms like fatigue, headaches, or weight changes
Meanwhile, try to maintain a regular sleep schedule, eat balanced meals, stay hydrated, and take short breaks from screens.
If the symptoms persist for more than a couple of weeks or are significantly affecting your studies or work, please consult a physician for a detailed evaluation. Basic tests such as a CBC, vitamin B12, iron studies, thyroid function tests, and blood
sugar may be advised based on your history and examination.
Wishing you good health.
