Study Notes

  • The session introduces major research topics in 21st-century academic examination of affective disorders.
  • Research aims for a comprehensive, mechanistic understanding of affective disorders.
  • Research is moving towards translational implications for people affected by affective disorders.

Recent Calls to Action and 21st Century Tools:

  • Discusses recent calls to action in researching unipolar depression and bipolar disorders.
  • Explores how the 21st century provides new tools to progress the field.
  • Covers hot topics in understanding mechanisms of illness and new treatments.
  • Discusses approaches to improving treatment outcomes for people with affective disorders.
  • There's increasing evidence and action to progress research related to affective disorders for patient benefit and reduced burden.
  • In February 2022, The Lancet issued a call to action for unipolar depression, needing united action from various sectors.

Key Messages from Call to Action:

  • High prevalence and poor detection of depression in health services needs addressing
  • Depression is heterogenous, unique, and complex, needing specific attention
  • Culture and prevention of illness are important factors.
  • Early detection, understanding patient needs, collaborative stepped care using guidelines, and person-centered/long-term care are essential.
  • Bipolar disorders have similar needs in collaborative care, complexity, severity, uniqueness, and improved diagnosis
  • There's a lack of quality care, especially in low to middle income countries.
  • Burden focuses on high heritability and premature mortality, greater in bipolar disorder but with lower prevalence.
  • Focus required on real world care, avoiding underuse of effective therapies like lithium and overuse of problematic treatments like antidepressants.
  • Emerging focuses or hot topics are common between bipolar and unipolar affective disorders.

Progress in Depression Research:

  • Publications on depression have increased annually for at least the last decade, as per academics in China.
  • Key themes include pathogenesis and mechanisms of depression, biological factors, and management including prevention and acute treatment.

Technology in Affective Disorder Research - 21st Century Players:

  • Technology is progressing understanding of affective disorders in all life aspects.
  • Smartphones, smart watches, etc., aid data collection using new measures like activity monitoring.
  • Activity monitoring tracks physical activity and sleep quality/amount/timings via accelerometers.
  • Passive smartphone data includes time, duration, app usage, and call/text information.
  • Actimetry and passive phone data can detect relapse in bipolar disorder, such as increased activity and reduced sleep during manic relapse or erratic phone use.
  • Passive monitoring can use microphone data, but it's less researched due to privacy concerns.
  • Speech and text data aids diagnostic accuracy and differentiation with patient consent.
  • EMA (Ecological Momentary Assessment) prompts participants for snapshot mood data and can identify risk factors for mood changes.
  • Smartphone applications are developed for various types of tailored data collection.
  • Technology enhanced data collection yields large amounts of deep, high frequency data for well powered, sensitive, high quality analysis.

Machine Learning:

  • Machine learning is increasingly used with high computing power for complex analyses in affective disorders.
  • It is a type of artificial intelligence with algorithms applied to data for predictions, delineating relationships between variables.
  • It can be thought of as a big regression analysis where variables predicting an outcome can be ascertained from input data.
  • Sufficient data is needed to train a model properly and avoid overfitting.
  • Overfitting is when the model fits the input data well but doesn't translate to new datasets.
  • Findings must be reliably replicated in subsequent studies.

Uses of Approaches:

  • Diagnostic/subgroup differentiation
  • Predicting outcomes (good/bad)
  • Picking up relapse or illness risk
  • Machine learning can identify factors indicating unrecognized bipolar disorder in depressed patients.
  • Gather data from patients, input data into a model based on available data and existing knowledge, train the model, test on new data, validate, use for early diagnosis.

Social Media:

  • Social media's relationship with mental health, especially suicide, is well-publicized.
  • Social media provides benefits/networks for individuals with social anxiety or severe mental illnesses.
  • It provides a platform for peer/public support and awareness.
  • Online text monitoring can show changing attitudes related to stigma and social support related to depression.
  • Potential harms are also present in, especially for young people, problematic smartphone use which sometime is regarded as addiction, needs to still be researched.
  • Increased social media use is linked to increased depression symptoms.
  • Internet based suicide interventions are in their infancy and developing still.

Pandemic:

  • There were widespread concerns in 2020 about potential impacts of lockdown, isolation, and COVID-19 illness on affective disorders.
  • Despite psychological distress, diagnosable mental illness prevalence may not have changed much, pending updates.
  • Those infected with Covid have been shown as having the same rate as the general population for clinically significant anxiety and depression.
  • High rates of distress were identified during lockdowns.
  • Diagnosed affective disorders didn't differ much from before the pandemic/previous pandemics
  • Lockdowns may have decreased social anxiety but increased health anxiety.
  • There is a lack of clarity surrounding the impact on healthcare service use/provision and well being of bipolar patients, with mixed findings
  • Evidence suggests bipolar patients exercise more virus safety, possibly due to anxiety/high comorbidity with physical health conditions.

Access to Adequate Care:

  • Access to adequate care regardless of economic/cultural factors is crucial, even for common illnesses like depression.
  • Challenges are pronounced in lower income areas, compounded by lack of cultural consideration in evidence-based interventions.
  • Straightforward interventions by lesser trained individuals are being prioritised globally, like psycho education
  • It is feasible in low-resource settings, requires less training/expertise, and is effective in groups, reducing cost per patient.
  • There is a need for culture and equanimity of people from diverse cultures.
  • Cultural adaptation of interventions is increasing The Friendship Bench started in Zimbabwe, adapts problem solving therapy, and is now cheap/quick, and is properly evidenced.
  • Those receiving the Friendship Bench intervention showed benefits related to depression severity and mental health symptoms.
