When changes in the EEG occur in the form of slow waves, what can this imply?

When slow waves appear in the EEG, it is often indicative of possible cerebral dysfunction or injury. These slow waves, which are typically characterized by lower frequency and higher amplitude compared to faster brainwaves, can signify various underlying issues in the brain. For instance, they may reflect altered neuronal excitability, decreased cerebral metabolism, or impaired function of cortical regions. Conditions such as encephalopathy, brain injury, or tumors may lead to these abnormal slow-wave patterns.

The presence of slow waves can provide critical clinical information, prompting further investigation into the patient’s neurological status. Essentially, this pattern suggests that something is affecting the normal functioning of the brain, warranting a closer examination to determine the underlying cause and potential treatment strategies.
