Depression - diagnosis and treatment

Depression is more than just a bad mood or temporary apathy. It is a serious mental disorder characterized by persistent low mood, loss of interest in life, and loss of energy that persists for weeks or months. According to the WHO, depression is the leading cause of disability worldwide and remains one of the most under-recognized disorders: most people live with the disease for years without seeking professional help.

At the K+31 Clinic, psychotherapists, psychiatrists, and clinical psychologists with many years of experience provide consultations. Diagnosis is comprehensive, and treatment is strictly individualized, taking into account the cause of the disorder, its severity, and the patient's personality.

Depression is a disease, not a weakness

It's important to understand: depression is not a personality trait or a consequence of "insufficient willpower." It's a medical disorder with specific biochemical mechanisms in the brain—an imbalance of neurotransmitters (serotonin, dopamine, norepinephrine). Like any other illness, depression requires professional diagnosis and treatment.

Without qualified help, depression tends to worsen symptoms and become chronic. Attempts to "pull yourself together," alcohol, or self-medication not only fail to help but often worsen the situation.

Causes of depression

Causes of depression

Depressive disorders arise from a combination of biological, psychological, and social factors.

Biological causes:

  • Genetic predisposition (risk increases if close relatives have had depression)
  • Imbalance of brain neurotransmitters (serotonin, dopamine, norepinephrine)
  • Hormonal changes: menopause, postpartum period, thyroid and adrenal diseases
  • Chronic somatic diseases: oncology, cardiovascular pathologies, neurological disorders
  • Taking certain medications (corticosteroids, beta-blockers, oral contraceptives)

Psychological causes:

  • Chronic stress and emotional burnout
  • Traumatic events: loss of a loved one, divorce, severe Illness
  • Low self-esteem, self-criticism, perfectionism
  • Childhood psychological trauma

Social causes:

  • Isolation and lack of close relationships
  • Problems at work, financial difficulties, family conflicts
  • Change in lifestyle, moving, retirement
  • Information overload and lack of rest

There is also endogenous depression, in which the disorder develops without an obvious external cause, solely based on internal neurobiological processes.

Symptoms of depression

Depression is diagnosed when symptoms persist for more than two weeks and significantly disrupt normal activities such as work, social interactions, and self-care.

Emotional symptoms:

  • A persistently depressed, sad, or "empty" mood
  • Anxiety without cause, a feeling of inner tension
  • Loss of interest in activities that previously brought joy (anhedonia)
  • A feeling of hopelessness and meaninglessness
  • Loss of self-esteem, guilt, a sense of worthlessness
  • Thoughts about death, about not wanting to live

Cognitive symptoms:

  • Difficulty concentrating and remembering
  • Slowed thinking, difficulty making decisions
  • Intrusive negative thoughts

Physical symptoms:

  • Persistent fatigue, loss of energy even after rest
  • Sleep disturbances: insomnia or, conversely, excessive sleepiness
  • Changes in appetite and weight (decrease or increase)
  • Body aches and pains: head, back, chest, abdomen - without an organic cause
  • Decreased libido

Diagnostics at the K+31 clinic

Diagnostics at the K+31 clinic

A diagnosis of depression is made based on a comprehensive assessment, which includes:

  • Initial consultation with a psychiatrist or psychotherapist - collection of anamnesis, assessment of the nature, severity, and duration of symptoms, identification of comorbid disorders
  • Standardized diagnostic questionnaires - Hamilton Depression Inventory, Beck Depression Inventory, PHQ-9, and others
  • Pathopsychological examination - assessment of cognitive functions, personality traits, and psychological defense mechanisms
  • Laboratory tests - complete blood count and biochemistry, thyroid hormones, vitamin D and B12, ferritin, hormonal profile (to exclude somatic causes of depression)
  • Consultations with related specialists - neurologist, endocrinologist, gynecologist - if necessary

It is important to rule out bipolar disorder. anxiety disorders, organic brain pathology, and somatic diseases that mimic depression.

Depression treatment methods in K+31

Treatment is always selected individually and, as a rule, combines several approaches.

Psychotherapy

Evidence-based psychotherapy is the primary and most effective treatment for mild to moderate depression. K+31 uses:

  • Cognitive behavioral therapy (CBT) – helps identify and change destructive patterns of thinking and behavior; one of the most studied treatments for depression with proven effectiveness.
  • Psychodynamic psychotherapy – works with the underlying causes of the disorder, past conflicts, and unconscious experiences.
  • Interpersonal therapy (IPT) – focuses on relationship problems, loss, and role conflicts.
  • Schema therapy – effective for chronic depression associated with early dysfunctional patterns.
  • Mindfulness-based therapy (MBCT) – reduces the risk of depressive relapse.

Pharmacotherapy

For moderate to severe depression, medication therapy is a necessary component of treatment. Psychiatrists at K+31 prescribe:

  • Antidepressants — medications are selected strictly individually, taking into account the clinical picture, the presence of comorbidities, and tolerability (SSRIs, SNRIs, tricyclics, and other groups)
  • Anxiolytics — for severe anxiety
  • Mood stabilizers — for bipolar depression or high risk of bipolarity
  • Anticholics — for severe forms with psychotic symptoms

The first effect of antidepressants is usually noticeable within 2–4 weeks. Self-discontinuation of medications without consulting a doctor is unacceptable.

Additional methods

  • Light therapy (phototherapy) is especially effective for seasonal depression.
  • Transcranial magnetic stimulation (TMS) is used for treatment-resistant forms of depression.
  • Physical therapy improves overall tone and reduces anxiety.
  • Physical therapy is proven to reduce the severity of depressive symptoms.
  • Lifestyle modification is recommended to normalize sleep patterns, nutrition, and social activity.

How is the treatment carried out?

  1. Initial consultation: The doctor collects the patient's medical history, assesses the condition, and rules out somatic causes.

  2. Diagnostics include testing, laboratory analysis if necessary, and consultations with related specialists.

  3. Development of an individualized plan—a combination of psychotherapy, medications, and supportive methods is determined.

  4. Treatment includes psychotherapy sessions, prescribed medications, and ongoing monitoring.

  5. Results evaluation and adjustments – the treatment plan is adjusted if necessary; drug tolerance is monitored.

  6. Relapse prevention – developing sustainable self-regulation skills, completing therapy

FAQ

How can you tell if it's depression and not just a bad mood?

A bad mood is a short-term reaction to a specific event that resolves within a few days. Depression is a persistent condition in which symptoms (depression, loss of interest in life, fatigue, sleep disturbances) persist for at least two weeks and interfere with normal functioning. Only a specialist can make an accurate diagnosis.

Which doctor should I see for depression?

Depending on the severity of the condition, see a psychotherapist or a psychiatrist. For mild to moderate depression, a psychotherapist is sufficient. For severe forms, suicidal thoughts, or the need for medication, see a psychiatrist. At K+31, the doctor will determine which specialist is needed in your specific case during your initial consultation.

Can I be registered?

No. Clinic K+31 is a private medical facility. A visit to a psychotherapist or psychiatrist here does not require registration, is not reflected on your driver's license, and is not transferred to your workplace. Doctor-patient confidentiality is strictly observed.

Is depression treated solely with medication?

No. Psychotherapy is the primary and independent treatment method for mild to moderate depression. For severe depression, a combination of psychotherapy and pharmacotherapy is most effective. The decision to prescribe antidepressants is made solely by a doctor.

How long does depression treatment last?

For mild cases, psychotherapy lasts from 8 to 20 sessions (2-5 months). For moderate and severe cases, treatment often lasts 6-12 months or more. Antidepressants are typically taken for at least 6 months after remission is achieved to consolidate the results and reduce the risk of relapse.

Can depression go away without treatment?

Some mild depressive episodes may resolve on their own, but without treatment, depression often becomes chronic or recurrs with greater intensity. Furthermore, the longer treatment is delayed, the more difficult it is to achieve lasting remission. If you are experiencing suicidal thoughts, delaying seeking professional help is unacceptable.

How should I prepare for my first appointment?

No special preparation is required. The doctor will be assisted by a rough description of how and when your symptoms began, a list of medications you're taking, and information about your medical history. There's no need to "invent" or "prepare" anything—the specialist will ask all the necessary questions.

The doctor helped me a lot. After being misdiagnosed and treated by other psychiatrists, I received the correct diagnosis and treatment, which is working and has made me a person with confidence in my psyche again.

Anna Konstantinovna! Thank you so much for your understanding, kindness, and help in analyzing my problems. We often approach psychotherapists with caution. This is wrong if you seek the RIGHT specialist. Anna Konstantinovna, despite her young age, possesses a gift that helps you understand from the very first session that you have met a true professional. Moreover, she possesses the human qualities necessary for this profession: empathy, sensitivity, respect, and a desire to understand and help. You simply talk, and in the process, you realize that she is simply helping you analyze the situation and find the methods that are right for you. She gave me tools that I can use on my own. I have been to her sessions six times, and I will definitely come back again.

Smolnikova Anna Olegovna

Dear Clinic! Thank you so much for your sensitivity and attentiveness to your clients. Your doctors are true healers and true professionals. I was amazed by the way I was examined by IV Sidorenko, Oksana Vladimirovna Baranova, VG Abalmasov, AA Medvedev, EN Malakhova, and SV Parinova – they were polite, courteous, and professional. I can say without laughing that after speaking with Anna Olegovna Smolnikova, Olga Viktorovna Kisel, and Anna Konstantinovna Eksel, I felt a huge improvement in my health, and they even gave me a lot of helpful advice. I also want to express my enormous gratitude to Natalia Gorelkova – she handled all the appointments so carefully, courteously, quickly, and politely in a short time – it was worth it. At the same time, you politely and persistently cared about how the client was feeling, whether they had eaten, whether there were any problems... - it touched my soul. ... I'm not afraid to say this - but in 8 hours of staying with you, I improved my health without any pills. A deep bow to all of you for your good deeds. I wish this were the case in all Moscow clinics. Thank you!
