Sleepwalking and night terrors are common in the ages of?

Sleepwalking and night terrors are indeed most common in children aged 3 to 12 years old. During this developmental stage, children experience a significant amount of non-REM sleep, which is where sleepwalking and night terrors typically occur. These phenomena are often linked to the brain's maturation process and the cycles of sleep that children undergo as they grow.

In young children, the neural pathways associated with sleep and arousal are still developing, which can contribute to episodes of sleepwalking and night terrors. As children progress through their early adolescence, the incidence of these behaviors tends to decrease as the nervous system matures and sleep patterns stabilize.

In contrast, the other age ranges provided are less relevant to these sleep disturbances. Although sleepwalking and night terrors can happen outside the primary age range of 3 to 12, they are significantly less common in older individuals, such as teenagers and young adults. Thus, the option related to children aged 3 to 12 years is the most accurate choice regarding the prevalence of sleepwalking and night terrors.
