Diagnosis Depression: Differences in Women and Men

Artefact theory explains that the differences in results are artificial rather than real. They are the results of multiple disparities in the measurement process.


 Artefact Theory 

The biological functions that differ between men and women, such as the status of hormones, may have an impact on mental health. Women who have premenstrual syndrome, postpartum depression, or depressive disorders throughout menopause may experience depressive moods as a result of hormonal variations related to reproductive body processes or reactivity to certain hormone levels.

Biological Impacts

- Socioeconomic conditions, family and relationships, social networks, and influencing variables related to the working world are significant elements in this regard. 
- Results show that lower social status and employment status of "unemployed/not working" are associated with a higher risk of depression diagnosis in males of working age compared to women of working age. 
- The influence of social support is more important for women than for males. - - It is also worth mentioning that special situations like living alone or being a single parent of one or more children can be mentally taxing for both men and women.

Effects of social living conditions

Based on the provided case study and your understanding of why certain mood disorders are more prevalent in women, analyze the combination of factors that are likely contributing to Maria's symptoms. Distinguish between the different categories of influence present in her situation.

Analyzing Contributing Factors to Depressive Symptoms

Research suggests that the higher prevalence of major depressive disorder among women compared to men is not merely a result of differences in reporting symptoms or seeking help. Evidence indicates that the gender disparity likely originates from a combination of biological factors and distinct environmental experiences related to gender.

Treatment resistant depression is generally acknowledged as depression which has not responded to a minimum of two different antidepressant medications. It is fairly common, with 60-75% of depressed patients meeting this criteria with a high severity and duration and increased exhibition of physical and mental symptoms that lead to higher dysfunction.

Treatment Resistant Depression

A depression relapse is another episode of depressive symptoms that happens fewer than six months  after symptoms have alleviated and remission was achieved.

Depression Relapse

Sleep disturbances are symptoms of depression that can persist during an episode or after an episode concludes. These disturbances can be seen in increased sleep onset latency (insomnia), frequent awakenings or arousals, increased wake after sleep onset, increased light sleep (stage 1), less deep sleep (slow wave sleep, sleep stages 3 or 4), subjective restlessness or feeling of being unrefreshed upon waking

Sleep Disturbances in Depression

Stressors can induce depression and depressive-like behaviors in mouse models, and this is associated with changes in microglia, particularly in the frontal cortex and the hippocampus. Furthermore, in post-mortem analysis of suicides, imaging reveals abnormal densities (both increased and decreased) of microglia in both MDD patients and in other psychiatric patients relative to healthy controls.

Microglia in Major Depressive Disorder

When a person is diagnosed with a physical chronic illness, due to the limitations caused as a result of pain, work absences, activity reduction, and temporary disabilities, there can be a co-morbid presentation of mental illnesses such as Major Depressive Disorder (MDD). 

Chronic Illness and Major Depressive Disorder

Different from a relapse, a recurrence is a new episode of depression that comes after six months of being treated and symptoms have been alleviated.

Exercise has widely been reported to enhance positive mood and reduce negative mood, based on self-reported questionnaires. The effects of exercise on mood is immediate and continues for about one day. Its benefits are maximized when subjects find the type of physical activity enjoyable.

Exercise and mood

Physical symptoms commonly presented in children diagnosed with Major Depressive Disorder include; achy stomaches, headaches, generalized pain, and gastrointestinal issues.

Common Physical Symptoms of MDD in Children

A significant comorbidity exists between obsessive-compulsive disorder (OCD) and major depressive disorder. Data shows that 41% of individuals with OCD also meet the diagnostic criteria for major depressive disorder. This relationship is often depicted in a Venn diagram, where the overlapping section of the two disorders' circles represents the percentage of co-occurrence.

Comorbidity of Obsessive-Compulsive Disorder and Major Depressive Disorder

The development of major depressive disorder is understood to be multifactorial, involving a combination of genetic, biological, and psychological explanations. Genetic research points to a heritable component, biological models often focus on neurotransmitter systems and brain structures, while psychological theories examine factors like cognitive patterns, life stressors, and learned behaviors.

Etiology of Major Depressive Disorder

An individual named Blake illustrates symptoms of a potential major depressive disorder. He experiences persistent crying, feelings of worthlessness and hopelessness, and a lack of energy so severe that he is unable to get out of bed.

Example of Major Depressive Disorder Symptoms

According to the DSM-5, Major Depressive Disorder is characterized by two primary symptoms. The first is a persistently depressed mood that is present for most of the day, almost every day, often manifesting as feelings of sadness, emptiness, or hopelessness. The second key symptom is a marked loss of interest and pleasure in activities that were previously considered enjoyable, such as hobbies, social events, or sports.

Defining Symptoms of Major Depressive Disorder (DSM-5)

An illustration of the loss of interest (anhedonia) seen in major depressive disorder is when an individual abandons hobbies they were once passionate about. For example, a person who was an avid tennis player might completely stop playing or showing any interest in the sport after developing the disorder.

Example of Loss of Interest in Major Depressive Disorder

A diagnosis of major depressive disorder requires that an individual experiences either a depressed mood or a loss of interest/pleasure in most activities for a minimum of two weeks. In addition to one of these core symptoms, the diagnosis also requires the presence of several other signs, which can include: significant weight changes (either loss or gain), sleep disturbances like insomnia or hypersomnia, observable psychomotor changes such as agitation (e.g., fidgeting, pacing) or retardation (e.g., slowed speech and movement), persistent fatigue, feelings of worthlessness or guilt, diminished ability to concentrate or make decisions, and thoughts of suicide.

Diagnostic Criteria for Major Depressive Disorder

Beyond the core symptoms of depressed mood and loss of interest, a diagnosis of major depressive disorder considers several other indicators. These include: significant changes in weight or appetite, sleep disturbances (insomnia or hypersomnia), observable psychomotor changes (agitation or retardation), persistent fatigue, feelings of worthlessness or excessive guilt, difficulty with concentration or decision-making, and recurrent thoughts of suicide.

Additional Diagnostic Symptoms of Major Depressive Disorder

Major depressive disorder is characterized by its episodic course, where symptoms reach their full intensity for a period before subsiding. While these episodes may extend for several months, about 70% of individuals recover within one year. Nevertheless, the disorder can have long-term consequences, with approximately 12% of individuals still showing significant impairment after five years. Furthermore, even among those who recover, many continue to experience minor, fluctuating symptoms over the long term.

Episodic Nature and Prognosis of Major Depressive Disorder

Major depressive disorder is a profoundly serious condition that severely diminishes an individual's quality of life. It can be incapacitating, leading to significant functional impairments such as an inability to attend work or school, the abandonment of career paths, and financial losses from lost wages. In some cases, the severity of the disorder necessitates hospitalization.

Life Impact of Major Depressive Disorder

A significant social consequence of major depressive disorder is discrimination. The majority of individuals with the disorder report experiencing such treatment, which in turn creates barriers to forming close relationships and pursuing opportunities in employment and education for which they are qualified.

Social Discrimination in Major Depressive Disorder

There is a significant link between major depressive disorder and physical health, particularly cardiovascular wellness. The disorder acts as a risk factor, increasing the likelihood of developing heart disease in otherwise healthy individuals. Furthermore, for patients who already have heart conditions, depression can lead to worse health outcomes.

Major Depressive Disorder and Cardiovascular Health

Major depressive disorder is so common that it is often called the 'common cold' of psychiatric disorders. Statistics from the U.S. indicate that each year, approximately 6.6% of the population experiences the disorder, while the lifetime prevalence, or the proportion of the population that will experience it at some point, is 16.9%.

Prevalence of Major Depressive Disorder in the U.S.

Explaining Gender Differences in Major Depressive Disorder Prevalence

The lifetime prevalence of major depressive disorder shows significant variation across different parts of the world. The highest rates are typically found in North and South America, Europe, and Australia, whereas the rates are observed to be substantially lower in Asian nations.

Geographical Differences in Major Depressive Disorder Prevalence

Studies indicate that the prevalence rates for major depressive disorder are higher among younger age groups when compared to older ones. A possible reason for this trend is that individuals in younger cohorts may be more inclined to acknowledge and report their depressive symptoms.

Age-Related Differences in Major Depressive Disorder Prevalence

Several risk factors are linked to major depressive disorder. These include socioeconomic factors like unemployment (which also applies to homemakers) and earning an annual income below \$20,000. Other associated factors are demographic, such as living in an urban environment, or relational, like being separated, divorced, or widowed.

Risk Factors for Major Depressive Disorder

Major depressive disorder often co-occurs with other psychological conditions. Specifically, there is a high rate of comorbidity with both anxiety disorders and substance abuse disorders.

Comorbidity of Major Depressive Disorder with Anxiety and Substance Abuse Disorders

In the DSM-5, specifiers are not considered distinct disorders but are labels used to describe specific patterns of symptoms or the timing of their occurrence in major depressive disorder. They provide a more detailed clinical picture. Examples of these specifiers include patterns related to seasonal onset, postpartum onset, chronicity, and features that are atypical, melancholic, or catatonic.

DSM-5 Specifiers for Major Depressive Disorder

The association between major depressive disorder and suicide is exceptionally strong, to the extent that the presence of suicidal thoughts is a formal criterion for diagnosing the disorder. This inclusion highlights the inherent and significant risk of suicide associated with this condition.

Suicidal Thoughts as a Key Criterion for Major Depressive Disorder
