Posted 11-10-2020

What are the Most Common Mental Disorders?

Humans respond to stress, loss, and adversity in a variety of ways. And naturally, we experience low mood and high spirits, we may lose sleep and appetite and avoid social situations. For the average person, the symptoms go away in a few days. But when they last longer than two weeks, it is no longer a normal reaction, but could be one of the many types of mental disorders.

The 5 Most Common Mental Disorders

There are many mental health disorders out there, and each has varying degrees of severity. But the five most common are as follows:

Mood Disorders

Mood disorders are also relatively common. Major depressive disorder (MDD) affects more than 15 million adults in the US and is the leading cause of disability for 15-45 year-olds. Other mood disorders include bipolar disorder, seasonal affective disorder (SAD), premenstrual dysphoric disorder, persistent depressive disorder (dysthymia), depression related to medical illness, and depression induced by substance use or medication.

These disorders can cause significant mood swings, shortness of breath, loss of appetite and sleep, dysfunctional personal or professional relationships, loss of interest in activities, and suicidal thoughts. These disorders can be debilitating if not treated properly.

Anxiety Disorder

A type of mood disorder, the effects of anxiety can be crippling for those who suffer from the disorder. With anxiety, you tend to worry excessively, and that worry can manifest in your life in various ways. The most common anxiety variations are generalized anxiety disorder (GAD), social anxiety disorder (SAD), and specific phobias or panic disorder.

Schizophrenia

This mental disorder has many stigmas, and some may think it only involves seeing things and hearing voices. But more than that, it changes how a person feels, thinks, acts, and understands reality. There are varying degrees of severity of this disorder like many others, and the spectrum might include characteristics from schizophreniform disorder, schizoaffective disorder, and brief psychotic disorder.

Personality Disorders

This group of disorders is commonly associated with changing thoughts, relationships, and moods, with side effects that make it difficult for individuals to have normal relationships and function well in their jobs. Some examples of personality disorders are borderline personality disorder, antisocial personality disorder, narcissistic personality disorder, avoidant personality disorder, dependent personality disorder, and obsessive-compulsive personality disorder.

Eating Disorders

Lastly, eating disorders affect 30 million adults in the USA today. These mental health disorders might include anorexia nervosa, binge eating, or bulimia. They can be onset by many factors, including low self-esteem, culture, or genetic biology.

Anorexia has one of the highest mortality rates of any of the mental health disorders. These disorders can be characterized by binging and purging, excessive exercise, laxative and diuretic use, obsessive calorie counting, dieting, or weight loss pursuits.
