The Top 10 Most Common Mental Disorders

Now we are going to talk about top 10 most common mental disorders in our Top 10 List. Mental disorder is a very common problem among the people in the world.

Most of the time people can’t realize its symptoms. We think we choose the right topics for our Top 10 List.


1. Antisocial Personality Disorder

We keep this mental disorder in the top place of our top 10 most common mental disorders.

Antisocial Personality Disorder is an alteration in the perception or experience of the external world so that it seems strange or unreal. It is the name for the Diagnostic and Statistical Manual of Mental Disorders or DSM.

DPD or Dissocial personality disorder is another name defined by the ICD or International Statistical Classification of Diseases. Though psychopathy or sociopathy has similar symptoms but scientists and doctors made clear that there are distinctive differences between them.

Common Symptoms

People having this mental disorder don’t care about others right, morals, feelings or social norms.

They will do everything they can to get what they want done, even violence or manipulating others are methods for them. Some common symptoms of Antisocial Personality Disorder are listed below:

  • Don’t care about social rules and regulation
  • Don’t have any respect for others feelings and rights
  • Can do anything like violence or manipulation to get what they want
  • Have no remorse for their harmful actions

  • Can’t maintain stable employment and have problem with social and financial obligations
  • Reckless and Impulsive
  • Low to zero care for their own or others safety
  • Addiction and abuse mentality
  • Can’t maintain stable relationship with family, friends or acquaintances

Causes or Reasons

There are mainly three causes or reasons for Antisocial Personality Disorder and they are genetic, physiological or environmental.

There may be other causes but those causes can be listed within those three causes.


Genetic: Research about genetic behavior shows that Antisocial Personality Disorder can be genetically transferred from generation to generation.

If a person has Antisocial Personality Disorder then any or some of his/her future generation members can have this problem. This problem roots within the gene so it can happen.

Physiological: If any traumatic event happens in anyone’s life then the after effect of that event can be the cause of this mental disorder. Mental shock or continuous rough situations can cause this problem.

If anyone has accident, and have physical head injury then that can also cause this. Head injury can be cured but the effect it leaves on the nerves can cause this problem.

Environmental: Family environment is a strong catalyst for mental growth moderation. If someone faces continuous mental pressures and harassment within their family then that can cause or trigger the Antisocial Personality Disorder.

This can also happen if school environment or job environment causes too much harassment on the mental situation.


Antisocial Personality Disorder is a complex and most difficult mental disorder to cure because the victim has low or zero remorse for their behavior and others problems.

They have no motivation to change and their lie and dishonest and seductive behavior can manipulate others to do wrong. So, staff, doctors and other patients even their family members need to be extra cautious during their treatment.

There is no specific drug or medication or supplement for this personality disorder problem. Carefully created environment with best suitable place and good behavior can be good process to treat this but isn’t guaranteed solution.

Regular counseling can be included with the treatment and BetterHelp online counseling is a better option. All the treatments therapists think or invented so far are case oriented, there have been no fixed treatment yet, research still going on for a large scale.
