Head injuries are a risk factor for Alzheimer’s disease. Wearing a helmet when riding a bike or playing contact sports and taking steps to prevent falls can help reduce this risk.
Head injury is the act of suffering trauma or damage to the head, skull, or brain, usually as a result of an accident, fall, violence, or sports. Head injury can have many harmful effects on our health, such as:
Causing bleeding, swelling, or bruising in the brain
Damaging the neurons, synapses, or blood vessels in the brain
Impairing the function of the brain regions that are responsible for memory and cognition
Increasing the risk of infections, seizures, or strokes
Affecting the mood, personality, or behavior
These effects may also increase the risk of developing Alzheimer’s disease or worsen its symptoms. According to some studies, people who have a history of head injury have a higher risk of developing Alzheimer’s or a related dementia than those who do not have a history of head injury . The exact mechanism of how head injury causes or exacerbates Alzheimer’s is not fully understood, but some possible explanations are:
Head injury increases the production of amyloid beta, a protein that accumulates in the brain and forms amyloid plaques, which are the hallmarks of Alzheimer’s disease.
Head injury triggers an inflammatory response in the brain, which may contribute to the development and progression of Alzheimer’s disease.
Head injury disrupts the function of tau protein, which stabilizes the microtubules that transport nutrients and molecules within the neurons. This may lead to the formation of tau tangles, which are another hallmark of Alzheimer’s disease.
Head injury alters the expression of genes and molecules that are involved in the development and progression of Alzheimer’s disease.
Therefore, protecting your head from injury may be a simple and effective way to prevent or delay Alzheimer’s disease. There are many ways to protect your head from injury, such as:
Wearing a helmet when riding a bike, motorcycle, skateboard, or scooter
Wearing a seat belt when driving or riding in a car
Avoiding alcohol or drugs that may impair your judgment or coordination
Following safety rules and precautions when playing sports or doing physical activities
Seeking medical attention immediately if you experience any symptoms of head injury, such as headache, nausea, dizziness, confusion, or loss of consciousness
The key is to be aware of the potential risks and hazards that may cause head injury and take preventive measures to avoid them. You can also combine head injury prevention with other healthy habits, such as diet, exercise, sleep, mental activity, or social interaction, to maximize your brain health and well-being.
