L3 depressive, substance use disorders Flashcards
distress
Distress refers to a person and/or their groups emotional experience – often
characterised by feelings of sadness, stress, frustration, guilt, agitation, anger etc.
dysfunction
Dysfunction occurs when a persons ability to maintain their normal behaviour in relationship with their group/relational norms. I.e. behaviour in daily activities, occupation and relationships becomes altered for a sustained period of time.
disability
Disability describes a loss of capacity to continue living a satisfying life as defined in relationship within a group. What is deemed to be ‘disability’ is highly dependent on the persons social and cultural environment.
problems with classification of mental disorders
In physical healthcare diagnosis is normally defined as, “the identification of a disease or condition by a scientific evaluation of physical signs, symptoms, history, laboratory test results and procedures.”
This approach is dependent on identifying illnesses based on objective data.
This approach is problematic in mental health because unlike physical illness, objective data such as pathology tests and x-rays cannot be used to identify any of the mental disorders.
Classification categories in mental health therefore rely on social constructs inferred from social expectations, norms and interests (business, political etc).
Throughout history there has been a lack of consistency and reliability in mental health diagnosis and classification (see lecture 1).
In the past 50 years there has been an exponential increase in the number of diagnostic categories of mental illness along with the removal of other categories since the first publication of diagnostic manuals in the 1950’s.
For example DSM-III listed 205 mental illnesses. In 2013 DSM-5 identified over 300 mental illnesses.
Both diagnostic manuals are intimately linked to the administration of private health insurance schemes and the administration of business and legal frameworks United States, UK, Australia etc (Susceptible to being influenced by money and power).
Cultural and gender bias, conflict of interest, medicalizing ‘normal’ behaviour (homosexuality removed in 1970’s).
Two main classification systems in mental health.
- International Classification of Diseases (ICD) - WHO.
- Diagnostic and Statistical Manual of Mental Disorders (DSM) – USA.
The value of classification of mental disorders
It is important not to throw the baby out with the bath water because mental distress, dysfunction and disability is experienced by a large proportion of people worldwide.
Classification systems of mental disorders within the ICD (since 1946) and DSM (since 1952) are not as objective as ICD classifications of physical healthcare but they are the best we have.
These systems have assisted society to move towards more humanistic approaches that are understandable and accessible to wider groups of people rather than historical approaches which were often influenced by race, sexuality and religion.
Based on similarity, problems and patterns can be identified.
These similarities contribute to the ongoing development of better healthcare, analysis, critic and development of novel approaches.
While these classification systems are useful we need to be cognizant that our actions as nurses will be highly influenced by the classification system and theoretical perspective we employ.
In this talk we will be referring to the ICD 11 Beta. (the latest version of ICD 11)
Successive national mental health surveys since 1997 have suggested that the most commonly experienced mental disorders in Australia are mood disorders, anxiety disorders and substance use disorders.
what is mood
A useful and important subjective emotional state, that influences personality and life functioning.
For example: sadness; happiness; elation.
Variations in mood are natural.
Mood is useful in a wide range of ways ie social interaction, physiological arousal, lethargy, art, music, love, intimacy, fear and anger.
Subjective awareness.
Psychodynamic defense.
Extremes in mood can be linked with extremes in human experience e.g. Creativity, despair, ecstasy.
mood flutuation
Mood fluctuations considered normal occur within socially accepted and personally manageable boundaries.
what r mood disorders
Disturbance of mood that has a sustained negative effect on a persons ability to maintain their normal activities (work/study) and relationships.
Several conditions and disorders of varying degrees of intensity (mild, moderate, severe) and duration.
Two common mood disorders are:
Depression
Bipolar disorder
depression
The word depression is often used to mean “feeling down” or “feeling blue.”
Most people experience feeling down every now and again, usually in response to life events/circumstances but are brief in duration.
When someone feels persistently sad and their mood begins to negatively effect their normal activities and relationships, they may be diagnosed as a depressive disorder.
When does ‘depression’ become a problem?
Depressive disorders are characterized by depressive mood (e.g., sad, irritable, empty) or loss of pleasure accompanied by other cognitive, behavioural, or neurovegetative symptoms that significantly affect the individual’s ability to function.
A depressive disorder should not be diagnosed in individuals who have ever experienced a manic, hypomanic episode or mixed episode, which would indicate the presence of a bipolar disorder.
Clustered symptoms of depression
- last more than 2 weeks
types of depression - single episode depressive disorder
Single episode depressive disorder is characterized by the presence or history of one depressive episode when there is no history of prior depressive episodes. A depressive episode is characterized by a period of almost daily depressed mood or diminished interest in activities lasting at least two weeks accompanied by other symptoms such as difficulty concentrating, feelings of worthlessness or excessive or inappropriate guilt, hopelessness, recurrent thoughts of death or suicide, changes in appetite or sleep, psychomotor agitation or retardation, and reduced energy or fatigue. There have never been any prior manic, hypomanic, or mixed episodes, which would indicate the presence of a bipolar disorder.
Depressive disorders according to intensity, mild, moderate and severe.
6A50.1Single episode depressive disorder, mild: None of the symptoms of the Depressive episode are present to an intense degree. An person with Mild depressive episode has some, but not considerable, difficulty in continuing with ordinary work, social, or domestic activities.
6A50.2 Single episode depressive disorder, moderate: In a moderate depressive episode, several symptoms of a depressive episode are present to a marked degree, and the person has considerable difficulty in continuing with work, social, or domestic activities, but is still able to function in at least some areas.
6A50.4 Single episode depressive disorder, severe: Either many symptoms are present to a marked degree or a smaller number of severe symptoms that include a significant risk of suicide are present. The individual is unable to continue with work, social, or domestic activities, except to a very limited degree.
Depressive disorders according to duration
6A51 Recurrent depressive disorder: Characterized by a history or at least two depressive episodes separated by at least several months without significant mood disturbance. There have never been any prior manic, hypomanic, or mixed episodes, which would indicate the presence of a bipolar disorder.
6A52 Dysthymic disorder: Characterized by a persistent depressive mood as reported by the individual (feeling down, sad) or manifested as a sign (i.e., tearful, downtrodden appearance) during more of the time than not over a period of at least 2 years. Most of the time, the number or duration of symptoms is not sufficient to meet the definitional requirements of a depressive episode. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning. There have never been any prior manic, hypomanic, or mixed episodes, which would indicate the presence of a bipolar disorder.
6A53 Mixed depressive and anxiety disorder: Mixed depressive and anxiety disorder is characterized by symptoms of both anxiety and depression more days than not for a period of two weeks or more. Neither set of symptoms, considered separately, is sufficiently severe, numerous, or persistent to justify a diagnosis of a depressive episode, dysthymia or an anxiety and fear-related disorder. Depressed mood or diminished interest in activities must be present accompanied by additional depressive symptoms as well as multiple symptoms of anxiety. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning. There have never been any prior manic, hypomanic, or mixed episodes, which would indicate the presence of a bipolar disorder.

what is mania
Mania differentiates depressive disorders from bipolar and related disorders. Mania is a mood state characterised by abnormally and persistently elevated or irritable mood, increased activity, and poor judgment.
e.g. pressure speech, skipping topics in conversation
