Which early sign indicates increased intracranial pressure (ICP) in a child?

The early sign indicating increased intracranial pressure (ICP) in a child is a change in behavior. This is often one of the first observable symptoms, as it can manifest as increased irritability, lethargy, or other alterations in their usual behavior and responsiveness.

Observing alterations in behavior typically indicates that the brain is under stress, which can be due to rising ICP. As the condition progresses, more severe symptoms may develop, but the subtlety of behavioral changes makes it a particularly important sign for parents and healthcare providers to monitor. Identifying these early shifts allows for timely intervention, which is crucial in managing ICP effectively.

In this context, while symptoms like vomiting, severe headache, and unresponsiveness are indeed associated with increased ICP, they tend to present at later stages or with more pronounced pressure changes. Recognizing behavior modifications first provides an opportunity for earlier diagnosis and treatment before progression to more serious complications occurs.
