adolescensen

Adolescensen is a term sometimes used to denote the developmental period between childhood and adulthood. While not widely used in English, it appears in some languages and scholarly texts as a variant of adolescence. The concept encompasses biological, psychological, and social changes that typically begin with puberty and extend into the late teens or early twenties.

The onset of adolescence usually begins in early adolescence, around ages 10 to 13 for many individuals, and ends in the late teens or early twenties, depending on the framework. Biologically, it involves pubertal development driven by hormonal changes, including growth spurts, development of secondary sexual characteristics, and changes in body composition. Neurologically, the adolescent brain undergoes continued maturation, notably in the prefrontal cortex and limbic system, affecting decision-making, emotion regulation, and risk assessment. Sleep patterns often shift, contributing to changes in mood and performance.

Psychologically and socially, adolescence is a time of identity formation, autonomy seeking, and expanded social networks, particularly with peers. Mood fluctuations, self-esteem challenges, and experimentation with values and roles are common. Mental health concerns, such as anxiety and depression, may emerge or intensify during this period, highlighting the importance of supportive relationships, education, and access to care.

Health, education, and policy contexts influence adolescent development. Adequate sleep, nutrition, physical activity, and safe sexual and reproductive health information support well-being. Cultural norms and legal frameworks shape expectations for schooling, work, and independence. Research on adolescents informs programs in schools, health care, and youth services aimed at promoting healthy transitions into adulthood.
