If your teen is having trouble concentrating, a therapist may want to rule out ADHD or PTSD. Or, if your teen seems depressed, a mental health professional may want to rule out bipolar disorder before making a depressive disorder diagnosis. 

Figuring Out the Right Diagnosis

Finding an accurate diagnosis for troubled teens can be difficult and initially several possible mental health disorders may seem to explain your teen’s emotional or behavioral problems. Because of this, the process of finding a correct diagnosis is conducted in a logical, step-by-step manner that considers all the possibilities, and then narrows them down to the diagnosis or diagnoses (sometimes more than one) that most closely match your teen’s symptoms. Getting the right diagnosis is extremely important in order to be able to successfully treat your teen’s symptoms. It’s a mental health professional’s job to use different methods to figure out exactly which disorder in the Diagnostic and Statistical Manual (DSM-5) fits your teen best.

An Example of the Difficulty of Diagnosis

Defiant behavior may be a symptom of several conditions, such as oppositional defiant disorder, depression, or substance abuse. But a little defiance may not necessarily signal a mental health issue. Oppositional behavior may also stem from past trauma or learned behavior from an unhealthy group of friends. The mental health professional evaluating this teen is likely to say, “First we will rule out depression, then we will consider other possibilities.”

Steps Mental Health Professionals Use to Rule Out Diagnoses

Mental illnesses aren’t always cut and dried. Professionals don’t simply use a checklist to arrive at a diagnosis. Instead, most conditions are diagnosed after a series of interviews where a clinician considers an individual’s background and environment. This is important because symptoms need to be taken in context. For example, a teen who is misbehaving at school may be acting out because they have a learning disability or because they are bullied, not necessarily because they have a primary behavior disorder.

How to Get Help For Your Teen

If you suspect your teen may have a mental health condition, seek professional help. Start by talking to your teen’s physician. Express any concerns you have about your teen’s mood or behavior. Your teen’s physician may make a referral to a therapist, psychiatrist, or other mental health professional. A thorough assessment and evaluation can help a clinician rule out specific mental health conditions while also arriving at an accurate diagnosis if a diagnosis is warranted.
