4 Types Of Mental Health Disorders In Adolescence

Although many adolescents have good mental health, it is estimated that 49.5% of them have experienced mental health problems at some point in their lives. The good news is that encouraging strong mental health can help to avoid some issues. Early intervention through therapy can help with mental health disorders in adolescence and ease the burden they have on their lives. In this article, we’ll cover some of the most common mental health issues they may go through. 

Is Poor Mental Health Common in Adolescence?

Adolescents commonly go through a wide variety of emotions as part of the normal developmental process. Teenagers may experience anxiety over their schoolwork and friendships, as well as depression following the loss of a close friend or family member. However, persistent symptoms that have an impact on a young person’s feelings, thoughts, and behavior are a hallmark of serious mental health issues.

Signs of Mental Health Disorder in Adolescence

In addition to interfering with daily routines and day-to-day functioning, mental health illnesses can also affect relationships, academic performance, sleep, and eating habits in adolescents. 

Here are some common signs that an adolescent may be suffering from a mental health disorder:

  • losing interest in hobbies they once loved
  • having little energy
  • having issues eating or sleeping
  • Spending more time alone and avoiding social events
  • Excessive diet, exercise, or binge-eating
  • Inflicting harm on themself (e.g., burning or cutting their skin)

Adolescents frequently suffer from anxiety, depression, attention deficit hyperactivity disorder, and eating disorders. Here’s a brief overview of each condition.
