Depression is a medical condition - not a personal failing, a character weakness, or a temporary mood that passes with time. It is one of the most prevalent psychiatric disorders in India, affecting an estimated 56 million people. The National Mental Health Survey (2015-16) found a current prevalence of 2.7% and a lifetime prevalence of 5.6%, with significantly higher rates in urban areas. Despite this, the treatment gap in India remains among the largest in the world - the majority of people with depression receive no clinical care.
At Athena Behavioral Health, depression treatment is psychiatry-led, evidence-based, and personalised across our NABH-accredited centres in Gurgaon, Delhi, and Noida. This page covers what depression is, how it is clinically assessed and diagnosed, what treatment involves across its full spectrum, and when residential care is the appropriate level of support.
What is Depression?
Major Depressive Disorder (MDD) - the clinical name for what is commonly called depression - is defined by the DSM-5 as the presence of five or more of nine specified Symptoms during the same two-week period, with at least one being depressed mood or loss of interest. Symptoms must represent a change from previous functioning and cause significant impairment in daily life.
Depression is episodic - a person may experience one episode in their lifetime, or multiple recurring episodes across years. Between episodes, the person may return to their baseline functioning. But untreated depression does not simply resolve - it tends to worsen, recur more frequently, and become progressively harder to treat with each successive episode. This is one of the strongest clinical arguments for early treatment.
Depression is not sadness. Sadness is a normal emotional response to loss or difficulty, is proportionate to its cause, and resolves as circumstances change. Depression is a persistent neurobiological state that is present regardless of external circumstances, does not respond to positive events, and cannot be overcome through willpower or attitude adjustment.
Signs and Symptoms of Depression
Emotional Symptoms
Persistent low mood-sadness, emptiness, or hopelessness present most of the day, most days, for at least two weeks
Anhedonia - loss of interest or pleasure in activities that previously brought enjoyment. This includes hobbies, socialising, food, and sex
Feelings of worthlessness, inadequacy, or excessive and disproportionate guilt
Hopelessness - the persistent belief that nothing will improve, that treatment will not work, that the future holds nothing worthwhile
In severe depression - thoughts of death, passive suicidal ideation ('I wish I wasn't here'), or active suicidal planning with intent
Physical Symptoms
Fatigue and loss of energy that does not improve with rest or sleep
Psychomotor retardation - noticeably slowed physical movements and speech, visible to others in the person's walking pace, response time, and facial expression
Or psychomotor agitation - inability to sit still, restlessness, and repetitive purposeless movement
Sleep disturbance - most commonly early morning waking (waking at 3–4am and being unable to return to sleep), though some experience hypersomnia
Appetite changes - reduced appetite with weight loss, or in atypical depression, increased appetite and weight gain
Cognitive Symptoms
Difficulty concentrating on tasks that previously felt effortless
Slowed thinking - thoughts feel heavy and effortful rather than flowing naturally
Impaired memory, particularly for recent events and new information
Negative cognitive bias - systematically interpreting neutral events negatively, catastrophising, and seeing only what is wrong
Difficulty making decisions, even minor ones
Behavioural Symptoms
Withdrawal from social life, family, and all non-essential activities
Neglect of personal hygiene, home environment, and responsibilities
In men: irritability, anger, and risk-taking behaviour are often more prominent than visible sadness - a presentation that delays recognition and treatment
Increased alcohol or substance use as self-medication
Depression in India - The Somatic Presentation
A clinically important feature of depression in India is the high frequency of somatic presentation - patients experiencing persistent headaches, body pain, fatigue, chest tightness, or gastrointestinal Symptoms as their primary complaint, without identifying low mood as the central problem. This reflects both genuine neurobiological changes (depression affects pain processing and physical functioning) and cultural patterns of emotional expression
Many people with depression in India first present to a GP, cardiologist, or neurologist with physical complaints, where the underlying depression is not identified. If you or someone you care about has unexplained physical Symptoms that have not responded to standard medical treatment, a psychiatric assessment may be warranted.
Types of Depression
| Type | Key Features | Typical Duration |
|---|---|---|
| Major Depressive Disorder (MDD) | Severe episodes of low mood, affecting all areas of life | Episodes last weeks to months |
| Persistent Depressive Disorder (Dysthymia) | Chronic, lower-grade depression lasting years | 2+ years continuous |
| Postpartum Depression | Onset after childbirth; affects bonding, daily function | Weeks to months post-delivery |
| Seasonal Affective Disorder (SAD) | Episodes linked to seasonal change, most often winter | Recurs annually |
| Treatment-Resistant Depression | Depression not adequately responding to 2+ medication trials | Ongoing; needs specialist care |
| Depression with Psychosis | Severe depression accompanied by hallucinations or delusions | Requires inpatient management |
Major Depressive Disorder (MDD)
The most common form. Involves one or more major depressive episodes meeting full DSM-5 criteria. Maybe a single episode or recurrent. Severity is classified as mild, moderate, or severe. Severe depression may include psychotic features - delusions or hallucinations with depressive content.
Persistent Depressive Disorder (Dysthymia)
A chronic, lower-grade depression lasting at least two years (one year in adolescents). The person is never symptom-free for more than two months at a time. Often described as 'always feeling like this - I thought it was just my personality.' Dysthymia responds to the same treatments as MDD but typically requires longer engagement.
Bipolar Depression
The depressive phase of bipolar disorder is clinically indistinguishable from MDD when assessed in isolation. Distinguishing bipolar depression from unipolar depression is clinically critical because the treatment differs - antidepressants given without a mood stabiliser in bipolar depression carry a documented risk of triggering a manic episode. If there is any possibility that depression may be part of a bipolar picture, this must be explored before antidepressant treatment is initiated. See the separate page on Depression vs Bipolar Disorder.
Postpartum Depression
Depression occurring during pregnancy or in the first year following childbirth. Affects approximately 1 in 5 women in India. Often dismissed as normal adjustment difficulties or hormonal changes, leading to significant under-recognition. Postpartum depression responds to the same treatments as MDD, with additional considerations around breastfeeding and infant care.
Treatment-Resistant Depression (TRD)
Approximately 30% of people with MDD do not respond adequately to two or more adequate antidepressant trials. This is clinically defined as treatment-resistant depression. TRD does not mean permanently resistant - it means resistant to the treatments tried so far. Specialist assessment frequently identifies either diagnostic issues, inadequate previous treatment, or concurrent conditions that explain the non-response. See Athena's dedicated page on Treatment-Resistant Depression.
How Depression is Diagnosed
Psychiatric Assessment
Diagnosis requires a qualified psychiatrist and a structured assessment - not a questionnaire or a brief GP consultation. The Athena assessment covers the full symptom picture, onset and duration, previous episodes and treatment history, family psychiatric history, current medications, physical health, substance use, and current level of functioning and safety. It typically takes 60–90 minutes.
Ruling Out Medical Causes
Several medical conditions produce depressive symptoms: hypothyroidism, anaemia, vitamin B12 and D deficiency, certain neurological conditions, and some medications. These must be excluded before a primary depressive disorder diagnosis is made. The psychiatrist reviews physical health and may request blood investigations where a medical contributor is suspected.
Assessing for Bipolar Spectrum
A critical part of the depression assessment is specifically enquiring about any history of manic or hypomanic episodes - periods of elevated energy, reduced need for sleep with sustained functioning, or uncharacteristic impulsive behaviour. This is not asked as a formality - it is a clinical safety check, because prescribing antidepressants in undiagnosed bipolar disorder carries specific documented risks.
Severity Assessment
Standardised rating scales - including the PHQ-9 (Patient Health Questionnaire-9) and Hamilton Rating Scale for Depression (HAM-D) - are used alongside clinical judgement to establish baseline severity and track treatment response. These tools are not diagnostic in themselves but provide objective anchors for monitoring change over time.
Depression Treatment - The Full Evidence-Based Pathway
Depression treatment is not one-size-fits-all. The appropriate combination and sequence of treatments depends on severity, episode history, response to previous treatment, co-occurring conditions, and individual clinical factors. Below is the full clinical pathway as practised at Athena Behavioral Health.
Mild depression - psychological treatment first
For mild depression, NICE guidelines recommend a structured psychological intervention - primarily Cognitive Behavioural Therapy (CBT) - as first-line treatment, with medication reserved if the psychological intervention does not produce adequate response. This reflects evidence that CBT is as effective as antidepressants for mild to moderate depression and carries no medication side effects.
Moderate to severe depression - combined treatment
For moderate to severe depression, the combination of antidepressant medication and psychological therapy produces significantly better outcomes than either alone. The APA and NICE guidelines both recommend this combined approach as standard of care. Starting both simultaneously rather than sequentially produces faster response.
Antidepressant medication - classes and selection
There are several classes of antidepressants used in India:
- SSRIs (Selective Serotonin Reuptake Inhibitors) - first-line for most people. Sertraline and escitalopram are the most commonly prescribed in India. Generally well tolerated, low overdose risk, suitable for long-term use. Typical therapeutic effect takes 4–8 weeks.
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) - venlafaxine and duloxetine. Useful when depression coexists with anxiety, chronic pain, or fatigue. Require dose tapering when stopping.
- Mirtazapine - particularly useful when depression is accompanied by severe insomnia and poor appetite. Works via a different mechanism. Often used as augmentation.
- TCAs (Tricyclic Antidepressants) - older class, still used in India in specific situations. Higher side effect burden than SSRIs/SNRIs. Require caution in overdose risk.
- Bupropion - useful when depression is accompanied by fatigue, hypersomnia, and lack of motivation. Also used for comorbid ADHD or smoking cessation.
Medication selection at Athena is based on the specific features of the depression, previous medication history, co-occurring conditions, side effect considerations, and individual factors - not on which medication is most familiar or most advertised.
Cognitive Behavioural Therapy (CBT)
CBT is the most extensively evidenced psychological treatment for depression and is recommended as first-line by both the APA and NICE guidelines. It works by identifying and modifying the negative automatic thoughts and cognitive patterns that sustain depression - the catastrophising, the personalisation of negative events, the filtering out of positive experiences, and the global negative self-assessment ('I am a failure') that depression produces.
CBT for depression also incorporates Behavioural Activation - structured re-engagement with rewarding activities, starting from a level that is achievable within the current state of depression and building progressively. This is particularly important because depression produces withdrawal, which reduces the positive input the brain receives, which worsens depression. Behavioural Activation interrupts this cycle from the behavioural end.
A full course of CBT for depression typically involves 12–20 sessions. At Athena, CBT is delivered by qualified clinical psychologists as part of the integrated treatment plan, in combination with psychiatric management.
Interpersonal Therapy (IPT)
IPT is particularly effective for depression that developed in the context of grief, relationship transition, interpersonal conflict, or role change - which is common. IPT helps the person address these specific life areas that are contributing to and maintaining the depression. NICE guidelines recommend IPT as a first-line option alongside CBT for moderate to severe depression.
Mindfulness-Based Cognitive Therapy (MBCT)
MBCT is specifically evidenced for preventing relapse in people with three or more previous depressive episodes. It combines mindfulness meditation practice with cognitive therapy principles to help people recognise early signs of depressive relapse and respond differently - with acceptance and disengagement rather than the ruminative engagement that tends to pull a person into a full episode. At Athena, MBCT is offered as part of the maintenance and relapse prevention programme.
When medication is not working - escalation strategies
If the first antidepressant does not produce adequate response after 4–8 weeks at an adequate dose:
- Dose optimisation - ensuring the person is on a therapeutic dose before switching.
- Medication switch - to a different antidepressant, potentially from a different class.
- Augmentation - adding a second medication to the primary antidepressant. Evidence-based augmentation agents include lithium (one of the most strongly evidenced approaches), atypical antipsychotics (quetiapine, aripiprazole), and mirtazapine.
- Referral to specialist - if two adequate antidepressant trials have failed, meeting TRD criteria, specialist assessment and advanced treatments should be considered.
For Treatment-Resistant Depression - Advanced Treatments
Where two or more adequate antidepressant trials have not produced adequate response:
- Electroconvulsive Therapy (ECT) - carries the highest response rate of any intervention for severe or treatment-resistant depression (60–80% response rate). Delivered under general anaesthesia. Primary side effect is short-term memory disturbance, which typically resolves.
- Repetitive Transcranial Magnetic Stimulation (rTMS) - non-invasive brain stimulation. No anaesthesia required. Response rates lower than ECT but well tolerated. Growing availability in India.
- Ketamine infusion - produces rapid antidepressant effect through NMDA receptor antagonism. Particularly useful when rapid response is urgent (severe suicidal ideation). Effects from single infusion last approximately 5–7 days.
Lifestyle and wellbeing as clinical tools
Sleep, physical activity, nutrition, and social connection all have direct, measurable effects on depression severity - not as alternatives to clinical treatment but as evidence-based adjuncts that significantly improve treatment outcomes:
- Sleep - disrupted sleep is both a symptom and a maintaining factor of depression. Structured sleep hygiene intervention is part of the clinical plan at Athena from the first appointment.
- Exercise - the most robustly evidenced lifestyle intervention for depression. Studies show aerobic exercise 3 times per week produces effect sizes comparable to antidepressants in mild to moderate depression.
- Social connection - depression produces withdrawal, which maintains depression. Structured social re-engagement - even in the absence of genuine desire to socialise - is part of Behavioural Activation.
- Alcohol reduction - alcohol is a CNS depressant and directly worsens depression; alcohol-depression co-occurrence requires concurrent management.
Residential Depression Treatment - When It Is Needed
Most depression is effectively managed in outpatient settings. Residential care becomes appropriate when:
Suicidal ideation is present with intent or plan - 24-hour clinical monitoring cannot be provided in outpatient settings
Depression is so severe the person cannot maintain basic self-care or take medication without supervision
Multiple outpatient treatment attempts have not produced adequate response
Depression co-occurs with substance use disorder requiring concurrent residential management
The home environment is not safe or therapeutically supportive
Athena Gurgaon provides psychiatry-led residential depression treatment with 24-hour medical monitoring, daily psychiatric review, individual and group therapy, structured daily programming, and family involvement. See the dedicated Residential Depression Treatment page for full detail.
The Role of Family in Depression Recovery
Family members are not bystanders in depression - they are integral to recovery. Research consistently shows that social support from close family is one of the strongest predictors of recovery and relapse prevention in depression.
What helps
- Consistent, non-pressuring presence - being available without demanding engagement or positive affect
- Practical support - managing medications, attending appointments, helping with meals and hygiene where the person cannot
- Recognising early signs of returning depression and prompting clinical contact before a full episode develops
- Understanding that 'pull yourself together' and 'think positive' are not only unhelpful but reinforce the person's sense of failure
What family members need too
Living with someone with depression is emotionally demanding. Family members of people with depression have significantly elevated rates of depression and anxiety themselves. Athena provides family counselling that is available to family members independently - you do not need to wait for the person to accept treatment before accessing support for yourself.

Frequently Asked Questions
How long does depression treatment take?
This varies significantly. An acute episode of moderate depression typically responds to 6–12 weeks of combined medication and therapy. However, treatment guidelines recommend continuing antidepressant medication for at least 6–12 months after remission to reduce relapse risk - longer in people with recurrent or severe episodes. Therapy may continue beyond this. For chronic or recurrent depression, long-term maintenance treatment is standard.
Can depression be cured permanently?
A single depressive episode can remit completely with treatment, and some people never experience a recurrence. However, for people with recurrent episodes, depression is a condition that requires ongoing management - including maintenance medication and monitoring. The goal is sustained remission and quality of life, not cure in the sense of eliminating all future risk.
Do antidepressants change your personality?
No. Antidepressants do not create a new personality or artificially elevate mood. They work to restore neurochemical functioning toward the person's baseline - the way they functioned before depression disrupted it. Most people describe feeling more like themselves on effective antidepressant treatment, not different.
Can depression be treated without medication?
Mild depression can respond to structured psychological treatment alone. Moderate to severe depression typically responds better to the combination of medication and therapy than to either alone. The decision about whether medication is needed is made individually following psychiatric assessment - it is not appropriate for every presentation but is clinically important for many.
What is the difference between depression and normal sadness?
Sadness is a normal emotional response to loss, disappointment, or difficulty. It is proportionate to its cause and resolves as circumstances change. Depression is a persistent neurobiological state that is present regardless of external circumstances, does not respond to positive events, lasts weeks to months rather than days, and causes significant functional impairment. The clinical threshold - two weeks of qualifying Symptoms with significant impact on daily functioning - provides a practical guideline.
Is depression hereditary?
Genetics contribute significantly to depression risk. First-degree relatives of someone with MDD have approximately 2–3 times the general population risk of developing depression. However, genetics establishes vulnerability, not destiny - environmental factors, treatment, and lifestyle all substantially influence whether that vulnerability produces a clinical episode.
Can depression cause physical Symptoms?
Yes. Depression commonly causes or worsens physical Symptoms including fatigue, headaches, body pain, gastrointestinal disturbance, and chest tightness. In India particularly, somatic Symptoms are frequently the primary presenting complaint in people with depression who have not yet recognised the psychological dimension. Depression also increases vulnerability to physical health conditions, including cardiovascular disease and diabetes.
