Common Types of Mental Disorders [Infographic]

Within a rehab facility, it’s quite common to find instances of dual diagnosis. When addiction occurs, a mental health disorder is usually present as well. Understanding the common types of mental disorders can help those find lasting recovery. So what are some types of mental disorders?

Understanding Types of Mental Disorders

While numerous mental health disorders exist, some are more present than others. Gaining knowledge about these issues can not only help those suffering but their families as well.


Depression can range over a wide variety of mental problems. While most of us will experience sadness and grief at some point in our lives, those suffering from depression are constantly sad. Depression means the absence of positive emotions or thoughts. Instead, the individual experiences a constant state of sadness or low moods. Symptoms can include:

  • Irritability
  • Social withdrawal
  • Ideas of self-harm
  • Loss of appetite
  • Muscle tension


Generalised anxiety disorder is when extreme feelings of uneasiness and worry occur over many days. While many of us will experience worry for one reason or another, those suffering from GAD have these feelings often and for long periods. They also find it hard to control these feelings. Symptoms can include:

  • Muscle tension
  • Irritability
  • Loss of sleep
  • Restlessness

Panic Disorder

A panic disorder can fall under GAD, but with an increase in feelings of fear and apprehension. Those suffering often experience panic attacks, which are short periods of intense panic. Attacks can occur randomly or because of a trigger. These triggers can be from an object, event, or thought.


Obsessive-compulsive disorder occurs when an individual is constantly experiencing obsessions and compulsions. Obsessions are thoughts that occur within the mind of the individual and are excessive or unreasonable. Common obsessions include:

  • Contamination
  • Fear of harm
  • Symmetry and order
  • Hoarding

Compulsions are repetitive mental behaviors or thoughts that the individual must perform. Common compulsions include:

  • Cleaning
  • Repeating words or prayers
  • Counting
  • Checking


Post-traumatic stress disorder occurs after one or more traumatic events take place. Individuals may distressingly re-experience the event. A reminder of the event can often cause flashbacks to occur. Those likely to suffer from this disorder include:

  • Members of the military
  • Survivors of natural disasters
  • Survivors of severe accidents
  • Victims of violence
