A qEEG brain map measures electrical activity in the brain. It is known as a quantitative electroencephalogram (qEEG). This test measures brain wave patterns and electrical activity that may be linked to some psychological symptoms or disorders, such as depression or anxiety. It can also be used to measure brain function and electrical abnormalities.

During the test, a cap with electrodes is fixed to the scalp, which then detects and measures electrical activity in the brain. These measurements are then recorded and analyzed to assess the activity in different brain areas. This information can help treat and manage certain conditions.

The qEEG brain map can measure different aspects of brain function, such as concentration and memory. It can also reveal differences in the activity of other brain regions, which may help understand certain psychological symptoms.

By measuring and analyzing the electrical activity in the brain, qEEG brain maps can provide valuable insights into how a person's brain functions and how they experience life. This information can be used to help identify, treat, and manage various psychological symptoms. Also, it can be used to assess the effectiveness of medications or other treatments.
