Practical Tips to Clear Brain Fog

9. An effect of allergies

Some argue that a clear link exists between brain fog and various allergies. Supporters of this theory explain how allergies to certain substances and food cause inflammations and they can produce symptoms associated with brain fog. For example, allergies may be behind the memory problems that are one of its most common and disturbing signs. They are also associated with the depression and anxiety that interfere with normal brain functioning.
