What a concussion looks like inside your 🧠

After sustaining a , the brain looks like a temporary metabolic chaos where brain cells stretch, release too many chemicals, and get deprived of fuel, disrupting neural connections. This is causing axons to shear, and leading to inflammation as the brain tries to fix itself.

Here are examples of what you don’t see and what you do:
•Invisible Damage: This microscopic damage and chemical imbalance usually doesn't show up on standard CT or MRI scans, which are better for structural issues like bleeding or fractures.
•Signs of Injury: Researchers use advanced techniques like diffusion imaging or animal models to see these changes, revealing disrupted white matter and cellular chaos.

Here are some examples of the cellular cascade:
•Shearing & Stretching: The sudden jolt makes the brain slam against the skull, causing neurons (brain cells) and their axons (nerve fibers) to stretch, twist, or tear, disrupting electrical signals.
•Chemical Dump: A "metabolic cascade" starts, dumping neurotransmitters (brain chemicals) everywhere, overwhelming the cells.
•Energy Crisis: Brain cells rapidly use up energy (glucose) trying to restore balance, while blood flow might decrease, making it hard to get fuel.
Inflammation: The brain's immune cells (microglia) rush in, swelling and causing inflammation as they try to patch up damaged barriers, further disrupting function.

Overall, everyone’s 🧠 is different so the damages to change. Plus there are NO mild injuries. However, understanding what happens in the brain during a concussion is the first step toward recognizing the signs, seeking help sooner , and making informed decisions as the brain recovers.

Rare Disease Day reminds us that behind every rare diagnosis is a person, a child, a parent, a friend, who deserves timely care, understanding, and opportunity. At NBI, we are proud to deliver essential plasma-derived medicines, including immunoglobulins used to treat primary immunodeficiencies and clotting factor products used to treat haemophilia, and other rare bleeding disorders.

This year’s theme, Equity, is a call to action: to strive for faster diagnoses, improved access to specialist care and life-saving therapies, and meaningful inclusion of patients in the decisions that shape lives.
Equity starts with awareness, it grows through action and it becomes real when we stand together. Let’s make equity visible wherever we live, learn, and work.

🌍 Why Blood Donation Matters
1. Saving Lives
One unit of blood can save up to three lives.

Blood is critical in emergencies, surgeries, childbirth complications, cancer treatments, and chronic illnesses.

In South Africa, blood shortages are common during festive seasons and school holidays, making donations especially vital.

2. Supporting the Healthcare System
Hospitals rely on regular donors to maintain a safe, stable supply.

Blood cannot be manufactured — voluntary donations are the only source.

Donors help ensure that patients in Potchefstroom and beyond have access to lifesaving transfusions.
