Understanding fatigue and changes in focus
Fatigue has many possible causes. Sleep, stress, medicines and medical conditions may contribute. Low energy or poor concentration alone does not establish a neurological condition.
Preparing for an assessment
Keep a short diary of sleep, daily activities, symptoms and medicines. Persistent or unexplained fatigue should be discussed with a healthcare professional; investigations and treatment depend on the suspected cause.
