Experts Link Post-Flu Brain Fog to H1N1 Recovery

Neurologists report that post-H1N1 'brain fog'—characterized by forgetfulness and difficulty concentrating—is often caused by systemic inflammation and disrupted sleep patterns during illness.

Dr. Ravindra Shrivastava noted that symptoms are more pronounced in severe cases involving hospitalization or low oxygen levels, though they do not necessarily indicate permanent brain damage.

Patients experiencing persistent cognitive issues for several weeks are advised to seek clinical assessment to rule out serious neurological complications beyond post-viral fatigue.
