Even after recovering from COVID-19, some health risks may still remain — especially related to the brain. Recent research suggests that inflammation in a specific part of the brain may increase the risk of developing Alzheimer’s disease later in life.
🧩 Which Part of the Brain Is Affected?
The inflammation is mainly seen in the Hippocampus, a small but very important part of the brain.
👉 The hippocampus helps with:
- Memory formation
- Learning new things
- Emotional control
Damage or inflammation in this area is strongly linked to Alzheimer’s disease.
🦠 How Does COVID-19 Affect the Brain?
Even after recovery, COVID-19 can:
- Trigger long-term inflammation in brain tissues
- Reduce oxygen supply during infection
- Cause immune system overreaction (cytokine storm)
- Lead to brain fog and memory problems
Persistent inflammation may slowly damage brain cells over time.
🧠 Why Does This Increase Alzheimer’s Risk?
Alzheimer’s disease develops due to:
- Build-up of abnormal proteins (amyloid & tau)
- Loss of brain cells
- Chronic inflammation
If COVID-19 increases inflammation in the hippocampus, it may:
- Speed up brain cell damage
- Worsen memory decline
- Increase the chances of early cognitive problems
⚠️ Symptoms to Watch After COVID-19
- Memory problems
- Difficulty concentrating
- Brain fog
- Mood changes
- Trouble finding words
If these symptoms last for months, medical advice is important.
✅ How to Protect Your Brain
- Regular exercise
- Healthy diet (Mediterranean-style)
- Proper sleep
- Mental activities (reading, puzzles)
- Manage blood pressure & diabetes
- Regular health check-ups
