Sometimes an injury damages the part of the brain that controls balance, sight, or hearing. Or memory loss may keep a person from remembering certain sights, sounds, smells, or tastes. Some people have trouble handling abstract ideas, like time, or they may simply lose track of what they are doing.

After a brain injury, a person may be less able to coordinate sequential activities, process thought, and use language. At first, therapy may be provided by medical professionals and therapists. But often longer-term support by family and friends is needed. Read on to learn more.

An electroencephalogram (EEG) is a test to find problems in the electrical activity of the brain. Read on to learn what happens before, during, and after the test.

Electroencephalography (EEG) is a test that measures your brain wave activity. Learn why it's used and how to prepare for the test.

From start to finish, your procedure will take about 30 to 60 minutes. The test may be done in a medical office. Sometimes the procedure is done in a radiology suite with X-rays as a guide.

A lumbar puncture is also called a spinal tap. It may be used to look for problems in your brain, spinal cord, and related structures.

Evoked potential tests measure the electrical activity in the brain as nerve pathways are stimulated.

Your healthcare provider may order evoked potential tests. These check the signals your brain and spinal cord (parts of your nervous system) receive from other parts of your body. They are also used to check for vision, hearing, and sensory or motor problems.

You will be having electromyography (EMG) and nerve conduction studies (NCS) to measure muscle and nerve function. In most cases, both tests are done.
