Chronic stress has been linked to an increased risk of developing Alzheimer’s disease. Find healthy ways to manage stress such as meditation or yoga.
Stress is the act of experiencing physical or emotional pressure, challenge, or threat, that triggers a response from the body and brain. Stress can have both positive and negative effects on our health, depending on its type, intensity, duration, and frequency. Some examples of stressors are:
Work-related stress, such as deadlines, workload, conflicts, or demands
Personal stress, such as family issues, financial problems, health concerns, or life events
Environmental stress, such as noise, pollution, traffic, or weather
Psychological stress, such as anxiety, fear, anger, or sadness
Stress can affect our brain health in various ways, such as:
Disrupting the balance of neurotransmitters and hormones that regulate mood, memory, and cognition
Increasing inflammation and oxidative stress in the brain, which may contribute to the development and progression of Alzheimer’s disease
Impairing the function of the blood-brain barrier, which protects the brain from harmful substances and pathogens
Reducing the production of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and survival of neurons and synapses
Interfering with the processes of neurogenesis and neuroplasticity, which are essential for the formation and maintenance of new memories
These effects may also increase the risk of developing Alzheimer’s disease or accelerate its onset. According to some studies, people who experience chronic or severe stress have a higher risk of developing Alzheimer’s or a related dementia than those who cope well with stress . The exact mechanism of how stress causes or worsens Alzheimer’s is not fully understood, but some possible explanations are:
Stress enhances the production of amyloid beta, a protein that accumulates in the brain and forms amyloid plaques, which are the hallmarks of Alzheimer’s disease.
Stress damages the hippocampus, a brain region that is involved in memory formation and consolidation, and is one of the first areas to be affected by Alzheimer’s disease.
Stress impairs the clearance of amyloid beta from the brain by reducing the activity of glymphatic system, a network of vessels that drains waste products from the brain.
Stress alters the expression of genes and molecules that are involved in the development and progression of Alzheimer’s disease.
Therefore, managing stress may be a simple and effective way to prevent or delay Alzheimer’s disease. There are many ways to manage stress, such as:
Practicing relaxation techniques or meditation
Engaging in physical exercise or hobbies
Seeking social support or professional help
Adopting a positive attitude or mindset
Setting realistic goals and priorities
The key is to find stress management strategies that suit your preferences, needs, and goals. You can also combine stress management with other healthy habits, such as diet, sleep, mental activity, or social interaction, to maximize your brain health and well-being.
