Which of the following describes the onset age profile for Rasmussen's encephalitis?

Rasmussen's encephalitis is a rare neurological disorder that is characterized by chronic inflammation of one hemisphere of the brain, leading to severe seizures and neurological deficits. The condition typically presents during childhood, with the majority of cases occurring in children between the ages of 1 and 14. This early onset is a critical aspect of Rasmussen's encephalitis, as it distinguishes the condition from other types of epilepsy that may present later in life.

Children who develop Rasmussen's encephalitis often show symptoms such as frequent seizures, progressive motor weakness, and cognitive decline, making early diagnosis and intervention crucial. The nature of the disorder, including its inflammatory basis and the impact on neurological function, showcases why the onset in childhood is a defining feature.

Options that suggest commonality in adolescents, adults, or the elderly do not align with the typical age profile of the disease, highlighting the importance of recognizing that Rasmussen's encephalitis primarily manifests in young children. This understanding is vital for healthcare providers in order to promptly identify and manage the condition.
