Hi – Came across this question looking for same information as posed here. This web page provides some helpful responses on this: http://www.jamesmorrisonmd.org/number-of-dsm-diagnoses.html – Official count of disorders in DSM-5 seems to be 157.

• 1.2.1 Neurodevelopmental disorders.
• 1.2.2 Schizophrenia spectrum and other psychotic disorders.
• 1.2.3 Bipolar and related disorders.
• 1.2.4 Depressive disorders.
• 1.2.5 Anxiety disorders.
• 1.2.6 Obsessive-compulsive and related disorders.
• 1.2.7 Trauma- and stressor-related disorders.
• 1.2.8 Dissociative disorders.

A mental disorder is a syndrome characterized by clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or developmental processes underlying mental functioning.

While it may be confusing that there are two systems for diagnosing mental health disorders, the important thing to remember is that the DSM-5 is primarily used in the United States while the ICD is used internationally and for insurance coding purposes.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) is the handbook used by health care professionals in the United States and much of the world as the authoritative guide to the diagnosis of mental disorders. DSM contains descriptions, symptoms, and other criteria for diagnosing mental disorders.

a ICD is more comprehensive than DSM. b DSM is more accurate than ICD. c ICD is the official international classification in psychiatry. d DSM is the only classification used in the USA.

The ICD is produced by a global health agency with a constitutional public health mission, while the DSM is produced by a single national professional association. WHO’s primary focus for the mental and behavioral disorders classification is to help countries to reduce the disease burden of mental disorders.

The DSM-5 gives clinicians with criteria and definitions to classify diseases symptomatically through a common language. Not only does it help in quick classification and diagnosis, but also streamlines patient care.

Thirty years ago the Institute of Medicine (IOM) analyzed the reliability of diagnoses coding from hospital discharge abstracts with the 8th Revision of the International Classification of Diseases (ICD) [1]. An independent re-coding of the principal diagnoses confirmed 65.2% of the original codes.

Summary: A new study has concluded that psychiatric diagnoses are scientifically worthless as tools to identify discrete mental health disorders. A new study, published in Psychiatry Research, has concluded that psychiatric diagnoses are scientifically worthless as tools to identify discrete mental health disorders.

The most common diagnostic system for psychiatric disorders is the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), currently in its fifth edition. While the last DSM, DSM-IV, used multiaxial diagnosis, DSM-5 did away with this system.

That is, the DSM is a medical-model manual that is nonetheless atheoretical about the causes of the mental disorders it catalogs. This may be confusing but important to keep in mind.

Today, the two most widely established systems of psychiatric classification are the Diagnostic and Statistical Manuel of Mental Disorders (DSM) and the International Classification for Diseases (ICD).

ICD-10

1. F0: Organic, including symptomatic, mental disorders.
2. F1: Mental and behavioural disorders due to use of psychoactive substances.
3. F2: Schizophrenia, schizotypal and delusional disorders.
4. F3: Mood [affective] disorders.
5. F4: Neurotic, stress-related and somatoform disorders.

The latest edition, DSM-5, published in 2013, provides a classification system that attempts to separate mental illnesses into diagnostic categories based on descriptions of symptoms (that is, what people say and do as a reflection of how they think and feel) and on the course of the illness.

What are some types of mental disorders?

• Anxiety disorders, including panic disorder, obsessive-compulsive disorder, and phobias.
• Depression, bipolar disorder, and other mood disorders.
• Eating disorders.
• Personality disorders.
• Post-traumatic stress disorder.
• Psychotic disorders, including schizophrenia.

Classification of Mental Disorders: Principles and Concepts In addition, researchers use mental disorder classifications to identify homogeneous groups of patient populations so as to explore their characteristics and possible determinants of mental illness such as the cause, treatment response, and outcome.

Mental and behavioural disorders are not just variations within the range of “normal”, but are clearly abnormal or pathological phenomena. One incidence of abnormal behaviour or a short period of ab- normal mood does not, of itself, signify the presence of a mental or behavioural disorder.

Mental Health & Behavioral Disorders

• Attention-Deficit / Hyperactivity Disorder (ADHD) ADHD, also called attention-deficit disorder, is a behavior disorder, usually first diagnosed in childhood.
• Autism Spectrum Disorder.
• Dysthymic Disorder.
• Eating Disorders.
• Generalized Anxiety Disorder.
• Learning Disorders.
• Obsessive-Compulsive Disorder.
• Obstructive Sleep Apnea.

Causes. No one knows the actual cause or causes of emotional disturbance, although several factors—heredity, brain disorder, diet, stress, and family functioning—have been suggested and vigorously researched.

These may include:

• attention deficit hyperactivity disorder (ADHD)
• oppositional defiant disorder (ODD)
• autism spectrum disorder (ASD)
• anxiety disorder.
• depression.
• bipolar disorder.
• learning disorders.
• conduct disorders.

Here are five effective strategies you can use to help EBD kids work well in an inclusive classroom.

1. Keep class rules/activities simple and clear.
2. Reward positive behaviors.
3. Allow for mini-breaks.
4. Fair treatment for all.
5. Use motivational strategies.

Students with emotional and behavioral disorders (EBD) are at greater risk for academic failure and negative postschool outcomes when compared to other disability categories. It is important to learn how to promote protective factors for students with EBD to foster resilience.

According to Gallaudet University, symptoms of an emotional behavioral disorder include:

1. Inappropriate actions or emotions under normal circumstances.
2. Learning difficulties that are not caused by another health factor.
3. Difficulty with interpersonal relationships, including relationships with teachers and peers.

Some of these immature, irritating, or thoughtless behaviors or “classroom incivilities” include:

• lateness or leaving early.
• inappropriate cellphone and laptop usage in class.
• side conversations.
• disregard for deadlines.
• grade grubbing.
• sniping remarks.
• cheating.
