EEG and cerebral palsy.

Electroencephalography (EEG) and Cerebral palsy (CP).

The value of electroencephalography (EEG) in the diagnosis of cerebral palsy (CP).

Very free interpretation

The importance of this method shouldn’t be exaggerated. In fact, it is a record of the brain activity in the form of curves. It looks like this.


For most people and even for some doctors this is a set of obscure curves. Sometimes the printout of curves is given to you and sometimes not. Almost always a very thorough medical description, filled with narrowly-specialized terms, is attached. The climax of the document is its conclusion, which points to the certain changes in the brain activity.

So EEG cannot show the following:

  • The level of your child’s mental development.
  • When he starts to move independently.
  • When he starts talking.
  • How effective was the course of motor rehabilitation.
  • EEG can neither confirm nor confute the diagnosis of cerebral palsy (CP).

However EEG can:

  • Indicate whether your child has a tendency to epileptic seizures.
  • Show what brain region wasn’t working properly at the time of the examination.
  • Show what brain structure or brain region is the most affected by cerebral palsy (it can be seen by several examinations over a period of years).

How often should you do EEG? There are no certain criteria, but always in cases of the child re-examination; in the selection of anticonvulsant therapy or by the decision of the attending doctor.

How dangerous is electroencephalogram? EEG is absolutely safe. In fact, it is recording electrodes «small microphones» attached to the head and that’s all.

How important is it for the doctor? Many doctors begin to treat EEG, but not the child, and this is not always good.
