Step 1: TESCA

At Brain Gain we evaluate a client’s cognitive ability in detail before and after training. This is essential because it helps to identify attention problems and determine the success of training by comparing results before and after training. Our clients complete the TESCA test that was specifically developed in South Africa. This comprehensive test measures 6 attention abilities, and screens for emotional and specific cognitive developmental issues that may hold someone back from reaching their full potential. The test takes 30 minutes to complete and the results are analyzed and recommendations are made.



Using the flow of healthy, oxygenated blood to the frontal lobe of the brain while a client participates in a cognitive activity (watching a program or playing a game), a feedback mechanism is created which indicates – in real time – how much attention the brain is paying to the task at hand. As long as the client remains focused on the activity, blood flow is naturally maintained or increased (through a clever physiological mechanism known as Neurovascular Coupling) and the program continues to play. The moment that the client becomes distracted and attention wanders, activity in the frontal lobe decreases, followed almost instantly by a drop in the blood flow and the program comes to a halt, alerting the client to their loss of focus. Only once they have regained their concentration and restored blood flow, does the program re-start.


Step 3: The EXCITING part!

Each client now does a second TESCA to compare post training results to pre-training results.
