When to consult a doctor for brain fog?

If brain fog lasts longer than usual

If you feel sluggish, forgetful, or unfocused for several days or weeks without improvement, it may be more than just tiredness. Persistent brain fog could point to a health concern that needs medical attention.

If brain fog is severe or has other symptoms

If your brain fog affects your memory, focus, or work performance, or if it comes with other symptoms like severe headaches, dizziness, vision changes, or mood swings, you need to consult a doctor immediately.

If brain fog occurs after injury or illness

If brain fog appears after a viral infection such as COVID-19, a head injury, or starting a new medication, it could be linked to certain conditions. It’s best to seek medical advice from a doctor.

Causes and symptoms

Brain fog causes

Treatment and prevention

Brain fog isn’t just feeling a little scattered. It can affect memory, concentration, and your ability to make decisions, often leaving you anxious, frustrated, or emotionally drained. Many people with brain fog also experience dips in their mood and motivation, which can impact daily life and mental well-being. Some prevention steps, after a GP consultation, can include:

Get quality sleep of 7–9 hours nightly.
Stay physically active through regular exercise.
Eat brain-friendly foods. Include omega-3-rich fish, berries, leafy greens, nuts, whole grains, and plenty of water.
Challenge your mind using puzzles, reading, learning new skills or languages, and memory games.
Practise mindfulness or meditation as it reduces stress.
Stay socially connected through engaging conversations and social activities
Chronic stress impairs memory; use relaxation techniques or hobbies you enjoy.
Limit alcohol and avoid smoking.
