Brain fog / concentration
Brain fog is a description of difficulties with thinking, concentration or memory, rather than a single diagnosis.
Anthony William’s proposed explanation; not an established medical cause
This department is a course in understanding, not a clinic. Nothing here is medical advice, diagnosis, or a treatment plan. If you are ill, pregnant, feeding a child, or taking medicine, speak with a clinician who knows your case. Emergency symptoms need emergency care.
William’s account
William attributes brain fog chiefly to viral neurotoxins and toxic metals, often involving the liver. His books and website elaborate this proposed mechanism.
Medical context
These symptoms do not establish metal poisoning or a chronic viral cause. Sleep, medicines, infections and other health conditions can be relevant. A smoothie has not been established here as a treatment for metal poisoning.
Read the medical reference for assessment and established care. William’s food and supplement recommendations are recorded as his approach, not a personalised treatment plan.
Foods named in the source

Care
Sudden confusion or new weakness, facial droop or speech difficulty needs emergency assessment. Persistent cognitive changes deserve a medical review.
