Neurologists Explain Brain Fog Symptoms, Causes, and When to Seek Medical Evaluation

Neurologists clarify that brain fog is a subjective symptom of mental slowness and concentration difficulty rather than a medical diagnosis or cognitive disorder.

Contributing factors include poor sleep, sleep apnoea, stress, anxiety, depression, thyroid disorders, nutritional deficiencies, and certain medications.

Doctors advise medical evaluation when cognitive difficulties persist despite adequate sleep, recur frequently, worsen gradually, or impair daily functioning.
