Alzheimer’s Disease: Understanding Risk Factors and Early Signs

Alzheimer’s disease is a neurodegenerative disorder that gradually affects memory, thinking, and the ability to perform daily tasks. Although the exact causes of the disease are not fully understood, numerous studies have identified risk factors that may contribute to its onset and progression.

At the Center for Neuroregenerative Medicine, we study Alzheimer’s risk factors and aim to explain which ones matter most, which are the most significant, and what early warning signs to watch for.

What Are the Risk Factors for Alzheimer’s Disease?

There are several factors that increase the likelihood of developing Alzheimer’s. Some cannot be changed, but others can be influenced by leading a healthy lifestyle.

Non-modifiable risk factors:

  • Age: The primary risk factor. After the age of 65, the likelihood of developing Alzheimer’s doubles every five years.
  • Genetics: A family history of the disease increases risk. In some cases, certain genetic mutations play a role in its development.
  • Sex: Women are at higher risk, possibly due to hormonal factors and longer life expectancy.

Modifiable risk factors:

  • Hypertension and cardiovascular disease: A healthy heart protects the brain. High blood pressure, elevated cholesterol, and diabetes increase the risk of cognitive decline.
  • Sedentary lifestyle: Lack of physical activity reduces oxygen supply to the brain and contributes to neuronal depletion.
  • Unhealthy diet: Diets high in saturated fats and sugar can harm the brain. The Mediterranean diet, rich in antioxidants and healthy fats, is recommended.
  • Stress and depression: Chronic emotional stress can accelerate cognitive decline.
  • Smoking and alcohol: Both habits negatively affect neurons and the vascular system.

Understanding Alzheimer’s risk factors is crucial because it allows for timely preventive measures.

Which Risk Factor Is the Most Significant in Alzheimer’s Development?

The most significant risk factor is age. After 65, the risk increases sharply. Although Alzheimer’s is not a natural part of aging, age-related changes in the brain may contribute to its development.

Other important factors include:

  • The accumulation of beta-amyloid and tau proteins, which form plaques and tangles in the brain.
  • Cardiovascular diseases that impair blood supply to the brain and accelerate neuronal damage.
  • Mild Cognitive Impairment (MCI): A condition where memory worsens more than normal aging and can precede Alzheimer’s disease.

At the Center for Neuroregenerative Medicine, we offer an alternative approach to supporting such patients — permanent auricular implantation, which stimulates the nervous system and helps improve quality of life in neurodegenerative conditions.

What Is Forgotten First in Alzheimer’s Disease?

Alzheimer’s develops gradually, and symptoms may appear in a different sequence for each individual.

The most typical early signs include:

  • Recent memory loss: Difficulty recalling what was eaten for breakfast or the content of a recent conversation.
  • Losing items: Misplacing keys, phones, or glasses.
  • Forgetting appointments and events: Failing to remember scheduled activities.
  • Forgetting names of acquaintances: A person may remember relatives but forget the names of friends.
  • Loss of everyday skills: Struggling with cooking, managing finances, or other routine activities.

For people at higher risk, these symptoms may appear earlier or be more pronounced. In the early stages, they are often attributed to stress or “just aging,” but if forgetfulness becomes systematic and interferes with daily life, it’s important to consult a specialist.

Healthy Habits and New Approaches

Although Alzheimer’s cannot be completely prevented, knowing the risk factors can help influence its course. An active lifestyle, balanced diet, and cardiovascular health monitoring can significantly reduce risks.

Lifestyle changes are key to prevention. Introducing healthy habits can substantially lower the likelihood of developing the disease.

At the Center for Neuroregenerative Medicine, we use innovative approaches such as permanent auricular implantation to help relieve symptoms and improve patients’ overall condition.
