In the 1960´s a psychologist by the name of Kazimierz Dabrowski claimed that people with high intelligence have something known as over excitability, which basically meant that their brains are almost hyper active. This leads to diverse mental health issues but also problems with physical health, such as allergies or autoimmune disorders.
People who have over excitability are almost too sensitive to the world around them both emotionally but also intellectually. They also tend to be very imaginative but are at the same time more sensitive to criticisms and rudeness. Some with over excitability reacts differently to being yelled at than someone who does not have over excitability.
Children who actually have over excitability can sometimes be misdiagnosed with ADHD. The child does in fact have a good ability to focus but needs more challenges and demands, which when they´re sadly not given in the school environment they appear to be unable to concentrate. Growing up like this is actually quite painful and the child is led to feel like an outsider when all they really need is a changed school environment.
Children with over excitability often also have a lot of energy and tend to be able to work for long hours as adults without tiring. They are sensitive to smells, touch and certain kinds of food but highly appreciative of beauty and comfort. Intellectually they read a lot, enjoy problem solving and analyzing and are also very curious. They have a good sense of humor and love fantasy, whether it is books, movies or to simply daydream about it.
Those were the positive traits but negatively speaking, people with over excitability are more inclined to suffer from anxiety, depression, and problems with adjusting to change, shame, guilt and extreme need for security as well as shyness and feelings of inferiority. They also tend to have physical issues such as stomach problems or headaches due to their anxieties. As children they need a lot more support then perhaps they are given. A child with over excitability doesn´t just get over things as quickly but needs help with working through his/her emotions.
Unfortunately if the child is not being given an optimal environment chances are that his/her talents will never fully rise to surface. They may linger and take a peek but they won´t reach their potential. Coping with over excitability is not always easy but it is encouraged that emotions are let out by for example tightly holding a pillow while rocking back and forth. It is good for people with over excitability to get out of their heads and drop down into the bodies.
People who are highly intelligent tend to have over excitability which leads to difficulties in life but not all highly intelligent suffer from mental disorders. People with over excitability tend to worry and stress more than people with high intelligence that don´t have it. This could be because those without over excitability may focus more on social interactions and physical exercise which both benefit mental health immensely.
If you have over excitability then you would probably benefit form mindful mediations as well as yoga; anything that has to do with connecting with the self, such as breathing or even being creative is helpful. Finding your tribe would be a move in the positive direction because living with heightened senses can make you feel like you don´t belong.
You also need to try to challenge yourself, meaning pressuring yourself in a positive way to do good, intellectually stimulating work as well as giving yourself time to relax in a beautiful and calming environment. Don´t discard your ability for imagination but use it, do something creative with it and remember to keep up your physical exercise and meditation practices.
