| Boilerpipe Text | A list of mental illnesses is a valuable tool. After all, the
term
mental illness
is incredibly broad and encompasses a great many
examples of mental illnesses
 and disorders. Having a list of mental illnesses to refer to when exploring what you or someone close to you might be experiencing can help you tame the jungle of information (
How Do You Know If You Have A Mental Illness?
).
The Officially Accepted List of Mental Illnesses
The recognized authority on mental illness types, descriptions, and criteria is the
Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)
,
published by the American Psychiatric Association (2013). It contains 20 chapters that delineate and describe all of the known mental disorders, well over 200. The chapters are organized logically, and each disorder within a chapter shares features in common with the others.
Below is a list of each mental illness disorder chapter in the DSM-5; it's a general list of mental illnesses. The list contains broad types of mental illnesses by category, but of course, each category contains multiple, more specific, mental illnesses.
Mental Illnesses List
Neurodevelopmental Disorders
These disorders involve problems, specifically with the brain, during development. The problems negatively impact life functioning. Typically, they begin in early childhood. They include:
attention deficit hyperactivity disorder (ADHD)
,
autism spectrum disorder (ASD)
,
communication disorders
,
intellectual developmental disorder
,
motor disorders
, and specific learning disorders. It’s not unusual for these disorders to co-exist.
Schizophrenia Spectrum and Other Psychotic Disorders
Disorders in this category involve
psychosis
, which is an episodic break from reality. Hallucinations (sensing things that aren't there) or delusions (believing things that aren't true or real) are the hallmarks of psychotic disorders (
Schizophrenia and Psychosis: Hallucinations and Delusions
). Other characteristics are present, too, depending on the specific disorder.
Bipolar and Related Disorders
These mood disorders involve extremes in affect (outward manifestation of emotions). The swings range from depression to
mania
, and they vary in severity according to the specific disorder (take the
Mood Disorder Questionnaire - MDQ
).
Depressive Disorders
Another type of mood disorder,
depressive disorders
 are characterized, among other symptoms, by prolonged depressed mood and loss of interest in activities.
Anxiety Disorders
Anxiety disorders
share in common intense worry and fear that affect thoughts, feelings, and behaviors, and physiology (digestive troubles, etc.)
Obsessive-Compulsive and Related Disorders
Obsessive-compulsive and related disorders
involve extreme recurrent thoughts or preoccupations connected to behaviors, mental or behavioral, done to alleviate the obsessions.
Trauma- and Stressor-Related Disorders
Trauma- and stressor-related disorders, such as
posttraumatic stress disorder
, are mental disorders resulting from outside forces. While they result from various types of injury, they significantly impact and/or alter the brain itself, thus qualifying as mental disorders.
Dissociative Disorders
With
dissociative disorders
, there's a disruption in the functioning of consciousness, memory, identity, or perception. Amnesia, senses of being unreal (depersonalization), or of the world being unreal (derealization) are some of the symptoms of these disorders.
Somatic Symptom and Related Disorders
Disorders in this category relate to physical symptoms that resemble a medical condition despite the fact that there is no medical evidence that the condition is present. This doesn't include
physical symptoms associated with anxiety disorders
.
Feeding and Eating Disorders
Extreme disturbances in eating behavior and nutrition are the hallmarks of
eating disorders
.
Sleep-Wake Disorders
These disorders involve disruptions somewhere in the
sleep-wake cycle
. Included features involve changes in the length/amount of sleep.
Elimination Disorders
Elimination disorders are those in which urine or feces is voided in inappropriate places, either voluntarily or involuntarily.
Sexual Dysfunctions
Disorders involving
sexual dysfunctions
 are those that relate to disturbances in sexual desire and response.
Gender Dysphoria
Gender dysphoria is a significant difference in the gender someone was born into and his/her experienced gender (
Multi-Dimensionality of Gender
).
Disruptive, Impulse-Control, and Conduct Disorders
Children with
conduct disorders
 present with irritable, angry, and/or disruptive behavior. Disobedience and other clashes with authority figures are common, and law-breaking behavior can also be present in this category.
Substance-Related and Addictive Disorders
This category includes the use or abuse of 10 separate classes of drugs.Â
Gambling
 behavior is also included here.
Neurocognitive Disorders
This category encompasses disorders/diseases of the brain that contribute to decline in cognitive functioning and processing.
Personality Disorders
The 10 main disorders in this category involve deeply ingrained behavior patterns and inflexible responses to various personal and social situations.
These aren't included in the same section of the DSM-5 as mental illnesses. Not every professional agrees on whether or not
personality disorders
 are mental illnesses due to the nature of the disorders and historical lack of evidence of brain dysfunction. As more becomes known about the brain, this may (or may not) change (
Difference Between Mental Illness and Mental Disorder
).
Paraphilic Disorders
Paraphilic disorders are ones that involve recurrent and
intense sexual urges, fantasies, or behaviors
. They involve unusual objects, activities, or situations.
Other Mental Disorders
This broad category is reserved for mental disorders that share symptoms with another mental disorder(s), are problematic, but don't meet the full diagnostic criteria of the disorder.
These categories, in the list of mental illnesses, provide an overview of the many different mental illnesses that people live with. Knowing the specifics of each category and each disorder within the categories creates understanding. Understanding brings empathy for individuals living with mental illness as well as hope that treatment and management are possible.

A list of mental illnesses is a valuable tool. After all, the [term *mental illness*](https://www.healthyplace.com/other-info/mental-illness-overview/mental-illness-definition-what-is-mental-illness "Mental Illness Definition: What is Mental Illness?") is incredibly broad and encompasses a great many [examples of mental illnesses](https://www.healthyplace.com/other-info/mental-illness-overview/examples-of-mental-illness "Examples of Mental Illness") and disorders. Having a list of mental illnesses to refer to when exploring what you or someone close to you might be experiencing can help you tame the jungle of information ([How Do You Know If You Have A Mental Illness?](https://www.healthyplace.com/other-info/mental-illness-overview/how-do-you-know-if-you-have-a-mental-illness "How Do You Know If You Have A Mental Illness?")).
## The Officially Accepted List of Mental Illnesses
The recognized authority on mental illness types, descriptions, and criteria is the *[Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)](https://www.healthyplace.com/other-info/mental-illness-overview/the-dsm-5-the-encyclopedia-of-mental-disorders "The DSM-5: The Encyclopedia of Mental Disorders"),* published by the American Psychiatric Association (2013). It contains 20 chapters that delineate and describe all of the known mental disorders, well over 200. The chapters are organized logically, and each disorder within a chapter shares features in common with the others.
Below is a list of each mental illness disorder chapter in the DSM-5; it's a general list of mental illnesses. The list contains broad types of mental illnesses by category, but of course, each category contains multiple, more specific, mental illnesses.
## Mental Illnesses List
### Neurodevelopmental Disorders
These disorders involve problems, specifically with the brain, during development. The problems negatively impact life functioning. Typically, they begin in early childhood. They include: [attention deficit hyperactivity disorder (ADHD)](https://www.healthyplace.com/adhd/adhd-children/what-is-add-and-adhd-add-adhd-definition "What Is ADD and ADHD? ADD, ADHD Definition"), [autism spectrum disorder (ASD)](https://www.healthyplace.com/neurodevelopmental-disorders/autism-spectrum-disorder/what-is-autism-spectrum-disorder-symptoms-causes-treatment "What is Autism Spectrum Disorder? Symptoms, Causes, Treatment"), [communication disorders](https://www.healthyplace.com/neurodevelopmental-disorders/communication-disorders/communication-disorders-articles "Communication Disorders Articles"), [intellectual developmental disorder](https://www.healthyplace.com/neurodevelopmental-disorders/intellectual-disability/mild-moderate-severe-intellectual-disability-differences "Mild, Moderate, Severe Intellectual Disability Differences"), [motor disorders](https://www.healthyplace.com/neurodevelopmental-disorders/motor-disorders/what-are-motor-disorders-signs-symptoms-causes-treatments "What are Motor Disorders? Signs, Symptoms, Causes, Treatments"), and specific learning disorders. It’s not unusual for these disorders to co-exist.
### Schizophrenia Spectrum and Other Psychotic Disorders
Disorders in this category involve [psychosis](https://www.healthyplace.com/bipolar-disorder/psychosis/a-technical-definition-of-psychosis "Technical Definition of Psychosis"), which is an episodic break from reality. Hallucinations (sensing things that aren't there) or delusions (believing things that aren't true or real) are the hallmarks of psychotic disorders ([*Schizophrenia and Psychosis: Hallucinations and Delusions*](https://www.healthyplace.com/thought-disorders/schizophrenia-symptoms/schizophrenia-and-psychosis-hallucinations-and-delusions "Schizophrenia and Psychosis: Hallucinations and Delusions")). Other characteristics are present, too, depending on the specific disorder.
### Bipolar and Related Disorders
These mood disorders involve extremes in affect (outward manifestation of emotions). The swings range from depression to [mania](https://www.healthyplace.com/bipolar-disorder/bipolar-symptoms/bipolar-mania-and-the-impact-of-manic-symptoms "Bipolar Mania and the Impact of Manic Symptoms"), and they vary in severity according to the specific disorder (take the [Mood Disorder Questionnaire - MDQ](https://www.healthyplace.com/depression/bipolar/mood-disorders-questionnaire "Mood Disorder Questionnaire - MDQ")).
### Depressive Disorders
Another type of mood disorder, [depressive disorders](https://www.healthyplace.com/depression/depression-information/types-of-depression-different-types-of-depression "Types of Depression") are characterized, among other symptoms, by prolonged depressed mood and loss of interest in activities.
### Anxiety Disorders
[Anxiety disorders](https://www.healthyplace.com/anxiety-panic/anxiety-disorders/what-is-an-anxiety-disorder-anxiety-disorder-definition "What Is an Anxiety Disorder? Anxiety Disorder Definition") share in common intense worry and fear that affect thoughts, feelings, and behaviors, and physiology (digestive troubles, etc.)
### Obsessive-Compulsive and Related Disorders
[Obsessive-compulsive and related disorders](https://www.healthyplace.com/ocd-related-disorders/ocd/what-is-obsessive-compulsive-and-related-disorders-in-dsm-5 "What is Obsessive-Compulsive and Related Disorders in DSM-5?") involve extreme recurrent thoughts or preoccupations connected to behaviors, mental or behavioral, done to alleviate the obsessions.
### Trauma- and Stressor-Related Disorders
Trauma- and stressor-related disorders, such as [posttraumatic stress disorder](https://www.healthyplace.com/ptsd-and-stress-disorders/ptsd/what-is-post-traumatic-stress-disorder-ptsd "What Is Posttraumatic Stress Disorder (PTSD)?"), are mental disorders resulting from outside forces. While they result from various types of injury, they significantly impact and/or alter the brain itself, thus qualifying as mental disorders.
### Dissociative Disorders
With [dissociative disorders](https://www.healthyplace.com/abuse/dissociative-identity-disorder/dissociative-disorders-types-list "Types of Dissociative Disorders, List of Dissociative Disorders"), there's a disruption in the functioning of consciousness, memory, identity, or perception. Amnesia, senses of being unreal (depersonalization), or of the world being unreal (derealization) are some of the symptoms of these disorders.
### Somatic Symptom and Related Disorders
Disorders in this category relate to physical symptoms that resemble a medical condition despite the fact that there is no medical evidence that the condition is present. This doesn't include [physical symptoms associated with anxiety disorders](https://www.healthyplace.com/anxiety-panic/anxiety-disorders/symptoms-of-severe-anxiety-feel-very-scary "Symptoms of Severe Anxiety Feel Very Scary").
### Feeding and Eating Disorders
Extreme disturbances in eating behavior and nutrition are the hallmarks of [eating disorders](https://www.healthyplace.com/eating-disorders/eating-disorders-overview/what-are-eating-disorders-eating-disorder-information "What are Eating Disorders? Eating Disorder Information").
### Sleep-Wake Disorders
These disorders involve disruptions somewhere in the [sleep-wake cycle](https://www.healthyplace.com/other-info/sleep-disorders/sleep-basics-why-we-sleep-and-how-sleeping-works "Sleep Basics: Why We Sleep and the Sleep Cycle"). Included features involve changes in the length/amount of sleep.
### Elimination Disorders
Elimination disorders are those in which urine or feces is voided in inappropriate places, either voluntarily or involuntarily.
### Sexual Dysfunctions
Disorders involving [sexual dysfunctions](https://www.healthyplace.com/sex/psychology-of-sex/types-of-male-and-female-sexual-problems "Types of Male and Female Sexual Problems") are those that relate to disturbances in sexual desire and response.
### Gender Dysphoria
Gender dysphoria is a significant difference in the gender someone was born into and his/her experienced gender ([*Multi-Dimensionality of Gender*](https://www.healthyplace.com/gender/inside-intersexuality/multi-dimensionality-of-gender "Multi-Dimensionality of Gender")).
### Disruptive, Impulse-Control, and Conduct Disorders
Children with [conduct disorders](https://www.healthyplace.com/other-info/psychiatric-disorder-definitions/conduct-disorder "Conduct Disorder") present with irritable, angry, and/or disruptive behavior. Disobedience and other clashes with authority figures are common, and law-breaking behavior can also be present in this category.
### Substance-Related and Addictive Disorders
This category includes the use or abuse of 10 separate classes of drugs. [Gambling](https://www.healthyplace.com/addictions/gambling-addiction/gambling-addiction-articles "Gambling Addiction Articles") behavior is also included here.
### Neurocognitive Disorders
This category encompasses disorders/diseases of the brain that contribute to decline in cognitive functioning and processing.
### Personality Disorders
The 10 main disorders in this category involve deeply ingrained behavior patterns and inflexible responses to various personal and social situations.
These aren't included in the same section of the DSM-5 as mental illnesses. Not every professional agrees on whether or not [personality disorders](https://www.healthyplace.com/personality-disorders/personality-disorders-information/what-is-a-personality-disorder-definition-causes-effects "What Is a Personality Disorder? Definition, Causes, Effects") are mental illnesses due to the nature of the disorders and historical lack of evidence of brain dysfunction. As more becomes known about the brain, this may (or may not) change ([*Difference Between Mental Illness and Mental Disorder*](https://www.healthyplace.com/other-info/mental-illness-overview/difference-between-mental-illness-and-mental-disorder "Difference Between Mental Illness and Mental Disorder")).
### Paraphilic Disorders
Paraphilic disorders are ones that involve recurrent and [intense sexual urges, fantasies, or behaviors](https://www.healthyplace.com/sex/psychology-of-sex/addictive-sexual-behaviors "Addictive Sexual Behaviors"). They involve unusual objects, activities, or situations.
### Other Mental Disorders
This broad category is reserved for mental disorders that share symptoms with another mental disorder(s), are problematic, but don't meet the full diagnostic criteria of the disorder.
These categories, in the list of mental illnesses, provide an overview of the many different mental illnesses that people live with. Knowing the specifics of each category and each disorder within the categories creates understanding. Understanding brings empathy for individuals living with mental illness as well as hope that treatment and management are possible.
