Symptoms and Assessment
Symptoms and assessment
Understand common depressive symptoms, diagnostic limits, bipolar screening and medical look-alikes.
Symptoms
Apathy and Depression
Apathy involves reduced motivation or initiative and can occur with depression, neurological illness, medication effects or other conditions. It is related to, but distinct from, sadness and loss of pleasure.
SymptomsDepression and Brain Fog
Depression can make thinking, memory, attention and decision-making feel slow or effortful. Sudden confusion, neurological signs or rapidly worsening cognition need urgent medical assessment.
SymptomsHypersomnia and Depression
Sleeping excessively or struggling to stay awake can accompany depression, but sleep disorders, medicines, substances and medical conditions can look similar and should be considered.
SymptomsInsomnia and Depression
Insomnia can be a symptom, risk factor and maintaining factor for depression. Treating sleep directly may help, while reduced need for sleep with high energy can signal hypomania or mania.
SymptomsDepression and Overeating
Appetite can increase during depression, sometimes alongside emotional eating, shame or loss of routine. Assessment should avoid blame and consider eating disorders, medicines, sleep and metabolic health.
SymptomsLoss of Appetite and Depression
Depression may reduce appetite and weight, but significant or unexplained changes need medical review. Hydration, nutrition, medication effects and physical illness may require attention.
SymptomsLibido and Depression
Depression can reduce sexual desire through mood, fatigue, relationship strain and changes in reward. Antidepressants and physical conditions can also contribute, so treatment decisions should be individualized.
SymptomsDepression and Erectile Dysfunction
Depression and erectile difficulties can influence each other. Cardiovascular, hormonal, medication, substance and relationship factors should be assessed alongside mental health.
SymptomsDepression and Procrastination
What looks like procrastination may reflect low energy, hopelessness, impaired concentration or tasks that feel overwhelming. Small behavioral steps can help, but persistent impairment is not a moral failure.
SymptomsIrritability and Depression
Depression can appear as irritability, anger or low frustration tolerance, particularly in young people and some adults. Bipolar symptoms, trauma, substance use and safety still require assessment.
SymptomsGuilt, Worthlessness and Depression
Excessive guilt and worthlessness can be central depressive symptoms and may distort how a person interprets responsibility. Severe self-condemnation or suicidal thoughts require prompt support.
SymptomsFatigue and Depression
Depression-related fatigue can affect physical energy, motivation and thinking. Anaemia, thyroid disease, infection, sleep disorders, medicines and other medical causes can overlap.
SymptomsEmotional Numbness and Depression
Emotional numbness may occur in depression, trauma-related conditions, dissociation or as a medication effect. Its timing and broader symptom pattern help guide assessment.
SymptomsDepression and Suicidal Thoughts
Suicidal thoughts can occur with depression but should never be treated as an inevitable symptom. Immediate danger requires emergency help; any suicidal thinking deserves direct, compassionate assessment.
SymptomsPassive Suicidal Ideation
Wishing not to wake up or feeling life is not worth living is clinically important even without a current plan. Support should assess intent, access to means, protective factors and changes over time.
Assessment
Depression Screening and What Comes Next
Questionnaires such as the PHQ-9 can organize symptoms and track change, but a score alone cannot establish diagnosis, rule out bipolar disorder or replace a safety assessment.
AssessmentHow Depression Is Diagnosed
Diagnosis considers the pattern, duration and impact of symptoms, suicide risk, physical health, medicines, substances, bereavement, trauma and any history of mania or hypomania.
AssessmentMild, Moderate and Severe Depression
Severity is not defined by a single symptom count. Clinicians also consider intensity, functional impairment, psychotic symptoms, self-neglect, suicide risk and available support.
AssessmentBipolar Depression vs Unipolar Depression
Bipolar depression can resemble major depression. A history of elevated or unusually irritable mood, reduced need for sleep, increased activity or impulsivity can change diagnosis and medication choices.
AssessmentBurnout vs Depression
Burnout is an occupational concept, while depression affects mood and functioning across contexts. They can overlap, and persistent loss of pleasure, hopelessness or suicidal thinking needs clinical assessment.
AssessmentBorderline Personality Disorder vs Depression
BPD and depression can overlap in low mood, emptiness, self-harm and relationship distress. The time course, triggers, identity pattern and broader history help clinicians distinguish and treat both.
AssessmentGrief vs Depression
Grief and depression can coexist. Grief often comes in waves tied to loss, while depression may involve pervasive loss of pleasure, worthlessness and impairment; context and safety matter.
AssessmentAdjustment Disorder vs Depression
Distress after a stressor may meet criteria for adjustment disorder or a depressive episode depending on symptom pattern, duration, severity and impairment. Labels should follow assessment, not assumptions.
AssessmentMedical Conditions That Can Resemble Depression
Thyroid disorders, anaemia, sleep disorders, neurological illness, infections and medication effects can contribute to depressive symptoms. New or unexplained symptoms warrant medical review.
AssessmentSerotonin and Depression
Depression is not adequately explained as a simple serotonin deficiency. Neurobiology is complex, and medication decisions should rest on overall evidence, likely benefit, harms and preference.
AssessmentRespiratory Depression Is a Medical Emergency
Respiratory depression means dangerously slowed or ineffective breathing and is not a form of depressive illness. It may be caused by opioids, sedatives or medical problems and can require emergency care.
