Treatment/Management of Brain Fog

Initially, you should speak to your GP regarding any health worries and/or potential side effects of medications which could be contributing to feelings of brain fog or cognitive dysfunction to rule out any medical causes. Blood tests, hormone levels and/or other investigations may be necessary to rule out any other underlying medical causes. You can also discuss medications with your GP to weigh up the risks and benefits and to discuss non-prescription alternatives. If your assessments show any significant cognitive deficits, you may be referred to one of the following services for further assessments and/or medical investigations:  

  • General Practitioner;
  •  Rehabilitation Services;
  • Memory Assessment Services;
  • Psychological Therapies
  • Neurology/ Neuro-psychology/ Neuro-Rehabilitation Services.

If your assessments do not show any significant cognitive deficits and your brain fog is felt to be related to non-medical reasons, current NICE Guidelines (NG188 – Managing the Long Term Effects of Covid-19) recommend education on managing Brain Fog for those experiencing the long-term side effects of Covid-19.


Post-Covid Brain Fog is thought, by researchers, to resemble Post-Concussive Syndrome (also inflammation) and treatment recommendations are similar (Weintraub, 2021).


As of now, the best treatment for brain fog caused by COVID-19 is fatigue management; cognitive rehabilitation and/or remediation; use of compensatory aids and strategies; and adopting healthy lifestyle habits of both body and mind.
