Key takeaways:
Cognitive-behavioral therapy (CBT) has long been recognized as a powerful tool in managing mental health disorders, but its potential role in preventing dementia is only beginning to be appreciated1,2. There are two ways that CBT can help. First, CBT is a powerful tool which can combat anxiety, depression, and other mental health disorders, which increase the risk of dementia3,4. Second, CBT can be used to facilitate habit change - that is to say, help users adopt behaviors which promote brain health.
How does CBT work?
CBT is a structured form of psychotherapy that relies on the principle of identifying and changing certain thought patterns and behaviors. The underlying principle is that the brain is “plastic” or flexible throughout life, which means that we can shape the connections our brain makes. The therapy is collaborative, with the client and therapist working together to set goals and practice new skills. The specifics of a CBT session will vary depending on the needs of each individual, but sessions generally involve recognizing distorted thinking, challenging irrational beliefs, and developing healthier responses. CBT also encourages behavioral changes by gradually facing fears or engaging in positive activities.
CBT in Alzheimer’s prevention
Combating mental illness
Your mental health is closely linked to your brain health. Depression, anxiety, and other disorders can actually increase inflammatory stress in your brain and disrupt your cognitive function. There are several different approaches to treating mental illness, and CBT happens to be highly effective for some people.
Forming healthy habits
Much of dementia prevention relies on addressing known lifestyle risk factors, things like physical inactivity, poor diet, diabetes, and high blood pressure. Forming and maintaining healthy habits can feel challenging, but CBT can help facilitate behavior change and keep you on the right track.
Common CBT principles
Because CBT is a tool, many of its principles apply just as well to managing mental health as to improving lifestyle habits. Common techniques include:
- Awareness and Identification: CBT begins with helping individuals become more aware of their current state. What situations or thoughts trigger a negative cascade? Which of my habits aren’t the healthiest?
- Cognitive Restructuring: This is a fancy way of saying challenging negative thoughts. By examining negative emotions and thoughts, individuals can start to think about them objectively. For mental health, this can be changing “something catastrophic will happen” to “I can take on this challenge.” For habit formation, this may be replacing "changing my diet won’t make a difference" with "every healthy meal contributes to my resilience."
- Behavioral Experiments: CBT employs behavioral experiments to challenge negative beliefs and test out new behaviors in a controlled manner. This may look like gradually facing a feared situation, engaging in activities that carry a sense of accomplishment, or starting to exercise with 10-minute daily walks. The purpose here is to gain confidence and reinforce the challenge to negative thoughts with real-life actions.
- Goal Setting: Together with a therapist, individuals set specific, achievable goals related to their needs. These may be thing like developing problem-solving skills to improve their sense of control, or things like increasing weekly physical exertion. The most important thing is for these goals to feel realistic and manageable.
- Reinforcement: Positive changes are reinforced through self-monitoring and resilience techniques. Tracking change over time helps establish a feedback loop where improvement becomes a natural motivator, while practical skills for managing setbacks help sustain long-term behavior change.
By systematically working through these steps, CBT provides individuals with the tools and confidence to implement and sustain changes - many of which contribute to preventing dementia.
A strong tool for prevention
It’s important to recognize that CBT isn’t a silver bullet - it’s a tool that’s helped millions of people, and it requires conscious work to implement. With that said, the potential of CBT in preventing Alzheimer’s is vast. It not only helps address mental illness, but also incorporates lifestyle changes that tackle the physiological underpinnings of dementia. Implementing CBT strategies that promote healthy aging could be key in reducing the burden of dementia, emphasizing prevention over treatment and maintaining cognitive vitality well into the later years of life.
Resources on finding CBT providers
If you are interested in trying CBT, there’s several ways to get started.
- Online directories and telehealth platforms can help you find a professional to work with. You can often find therapists through your insurance plan or your employee benefits, or through listing websites like Zocdoc or Psychology Today. You can also look on telehealth platforms like Talkspace or Betterhelp, though not all of these accept insurance.
- Community health centers often also provide CBT services. These are typically available at reduced rates, and focus primarily on mental health.
- Books can help you learn more about CBT and its practice. Feeling Great: The revolutionary new treatment for depression and anxiety is a widely praised book by Dr. David Burns, a psychiatrist and professor of Psychiatry at Stanford.
