How is Brain Fog diagnosed?

Share

See your doctor if you have a persistent lack of clarity that worsens or doesn't improve. A single test can't diagnose brain fog. 

Brain fog may signal an underlying issue, so your doctor will conduct a physical examination and ask about your: 

  • Mental health 
  • Diet 
  • Level of physical activity 
  • Current medications or supplements 

You should let your doctor know about other symptoms you might have. For example, someone with hypothyroidism may have brain fog along with hair loss, dry skin, weight gain, or brittle nails. 

Blood work can help your doctor identify the cause of brain fog. A blood test can detect the following: 

  • Abnormal glucose Ievels 
  • Poor liver, kidney, and thyroid function 
  • Nutritional deficiencies 
  • Infections 
  • Inflammatory diseases 

Based on the results, your doctor will determine whether to investigate further. Other diagnostic tools may include imaging tests to look inside the body, such as X-rays, MRI, or CT scans. The doctor may also conduct allergy testing or a sleep study to check for a sleep disorder. 

Keeping a food journal can help you determine if your diet contributes to brain fog.
