How Your Brain Type Affects Your Relationships

Written by Dr. Daniel Amen | January 13, 2020

Did you know that the way you think, act and interact with others can be dependent on how your brain functions? This has been determined by the largest database of brain scans related to behavior in the world at Amen Clinics. Through the evaluation of thousands of brain scans, we are now able to attribute certain brain patterns to how you relate to others, which can affect relationships.

In our brain imaging work at Amen Clinics, we began by looking for patterns that could help us diagnose and treat mental health conditions. After studying more than 150,000 brain SPECT scans that measure blood flow and activity, we also realized that certain brain patterns corresponded to personality types. Based on our research, we have identified five primary brain types that influence who you are, how you behave, and how you relate to others.

Brain Type 1 — Balanced

Personality: You're likely to be focused, flexible, and emotionally stable. You're one of those people who gets things done on time, shows up on time, follows through on promises, and copes well with life's ups and downs. In general, you aren't much of a risk taker and you prefer to follow the rules.

Relationships: You tend to play well with others and have drama-free relationships.


Brain Type 2 — Spontaneous

Personality: You love trying new things, have a wide range of interests, and would rather do things on the spur of the moment than have a set schedule. You think outside the box, don't believe that rules apply to you, and are typically late for appointments. Organization isn't your strong point, and you're such a risk taker that your behavior might get you into trouble.

Relationships: Because you like excitement in your life, you may have a tendency to create drama in your relationships.

Brain Type 3 — Persistent

Personality: You like to get things done. You tend to be strong-willed. You like routines and have trouble going with the flow. You may be a worrier who has trouble letting go of past hurts, and you tend to be argumentative.

Relationships: You can be stubborn and tend to remember every fight you and your partner ever had.

Brain Type 4 — Sensitive

Personality: You tend to have great empathy for your those you are surrounded by. You can be deeply moved by art. You may shy away from violent films, hateful social media posts, and the nightly news. You may struggle with moods, can feel overwhelmed, and are likely to have lots of automatic negative thoughts (ANTs).

Relationships: You're so tuned in to others that it's easy for you to tell when your partner needs a hug or needs some space. Because you're so sensitive to external stimuli, you sometimes need alone time to recharge, which your significant other may take personally.

Brain Type 5 — Cautious

Personality: You're likely to feel anxious, which typically makes you more prepared. If you are of this type, you'll tend to have such a busy mind that it's hard to relax. You may tend to expect the worst and have a fear of failure that prevents you from going for your dreams.

Relationships: You may have a fear of rejection and seek constant reassurance from your partner, which can come off as being needy or clingy.
