What can lead to the development of breach rhythm in EEG studies?

The development of breach rhythm in EEG studies is primarily associated with skull defects. Breach rhythm refers to a specific pattern observed on an EEG that indicates an abnormality in the brain's electrical activity, typically occurring in the presence of a bony defect in the skull, such as from previous surgery or trauma. This defect allows for abnormal electrical signaling in the brain to occur, leading to the characteristic EEG findings of breach rhythm.

When the skull is compromised, the electrical signals from the brain may escape more readily, resulting in unusual EEG patterns. This phenomenon is particularly noted in patients who have had surgeries, such as craniotomies, or those with congenital skull malformations. The identification of breach rhythm can help healthcare professionals in diagnosing the underlying conditions related to the skull's integrity and the brain's compensatory mechanisms.
