Diagnosis And Definition of Treatment-Resistant Depression

Dr. Zaheer Aslam • January 27, 2024

In today's society, the topic of mental health has become increasingly prevalent. However, one aspect that is often overlooked and not fully understood is treatment-resistant depression.


This condition affects millions of individuals worldwide and can be incredibly debilitating for those who suffer from it. Despite its impact on people's lives, there is still much confusion surrounding its diagnosis and available treatments.


In this blog post, we will delve into the definition of treatment-resistant depression and explore the various methods used to diagnose this complex disorder. By gaining a better understanding of this condition, we hope to bring awareness and educate our readers on how to identify it in themselves or their loved ones.

Understanding Depression and Its Prevalence

Depression, classified as a mood disorder, is marked by persistent feelings of sadness, loss of interest, and a lack of enthusiasm for activities once enjoyed. It is a common mental health issue, with the World Health Organization (WHO) reporting around 264 million individuals being affected globally.


Depression ranges in severity from mild to severe, with severe cases sometimes leading to self-harm or suicide. The ubiquity and severity of depression underscore the importance of understanding this condition, particularly its treatment-resistant form.


Despite its prevalence, the stigma around mental health often hinders individuals from seeking support and treatment. Bringing awareness to this disorder aims to counter this stigma and promote mental wellness.

Treatment-Resistant Depression: Definition and Diagnosis

Treatment-Resistant Depression (TRD) is a specific form of depression characterized by the lack of adequate response to at least two different antidepressants from different classes, each taken for a sufficient duration at an

adequate dose.


It is considered a severe and complex form of depression that is particularly challenging to treat. Despite numerous attempts with various medications and therapies, individuals with TRD may find little to no relief, leading to a significant impact on their quality of life.


Diagnosing TRD involves a comprehensive evaluation. Firstly, a psychiatrist or mental health professional will ensure that the diagnosis of depression is correct and that the individual has adhered to a full course of treatment at the appropriate dose.


They will then explore the possibility of other factors contributing to the resistance to treatment, such as co-existing mental health disorders, chronic health conditions, or substance abuse.


The individual's personal life, including their relationships, employment situation, and overall lifestyle, may also be examined to ascertain any potential external factors influencing the depression's resistance to treatment.

Factors Contributing to Treatment-Resistant Depression

Several factors may contribute to Treatment-Resistant Depression (TRD),

making it a multifaceted problem.

Genetic predisposition plays a significant role in the development of TRD. Certain individuals may have a genetic makeup that makes them less responsive to the antidepressant medications typically used to

treat depression.

Another critical factor is the presence of additional mental or physical health disorders. For instance, anxiety disorders, personality disorders, and chronic physical illnesses can complicate the treatment of depression and make it more resistant to treatment.

Lifestyle factors can also contribute to TRD. This includes substance abuse, poor nutrition, lack of physical activity, and inadequate sleep, which can all increase the severity of depression and reduce the effectiveness of treatment.

Lastly, environmental factors such as chronic stress, traumatic events, and

exposure to physical, sexual, or emotional abuse can significantly influence the

development and treatment resistance of depression. Understanding these

contributing factors is crucial in devising an effective treatment plan for TRD.

Medications Commonly Used to Treat Depression

Antidepressant medications are generally the first line of treatment for depression. They come in various classes, including Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin and Norepinephrine Reuptake Inhibitors

(SNRIs), Tricyclic Antidepressants (TCAs), and Monoamine Oxidase Inhibitors (MAOIs).

  1. Selective Serotonin Reuptake Inhibitors (SSRIs): SSRIs, such as Fluoxetine, Sertraline, and Citalopram, are among the most commonly prescribed antidepressants. They work by increasing the level of serotonin, a neurotransmitter associated with mood, in the brain.
  2. Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs): SNRIs, including Venlafaxine and Duloxetine, act on both serotonin and norepinephrine neurotransmitters and are often used when SSRIs are ineffective.
  3. Tricyclic Antidepressants (TCAs): Although not commonly used as a first-line treatment due to their side effects, TCAs like Amitriptyline and Nortriptyline can be effective in treating certain cases of depression.
  4. Monoamine Oxidase Inhibitors (MAOIs): MAOIs, such as Phenelzine and Moclobemide, are typically used when other antidepressants don't work. They can have serious side effects and require a strict diet due to dangerous food interactions.


It's important to bear in mind that the effectiveness of antidepressants varies from person to person, and what works best will depend on the individual's specific symptoms, overall health, the presence of co-occurring mental or physical health disorders, and their response to medication. As such, it may take time and patience to find the most effective medication and dosage for each person.

Exploring Alternative Therapies for Treatment-Resistant Depression

For those who find little relief from traditional antidepressant medications, alternative therapies may present a viable option. A holistic approach to managing depression can encompass various strategies, from lifestyle changes

to novel treatments.

Psychotherapy: In some instances, combining medication with psychotherapy can be more effective than medication alone. Cognitive-behavioral therapy (CBT) and interpersonal therapy (IPT) are commonly used psychotherapeutic approaches.

Electroconvulsive Therapy (ECT): Often reserved for severe, life-threatening cases of depression or when all other treatment options have failed, ECT involves passing electric currents through the brain to impact the function and effect of neurotransmitters in your brain to relieve depression.

Transcranial Magnetic Stimulation (TMS): TMS is a noninvasive procedure involving a magnetic field to stimulate brain nerve cells. It's often considered when standard treatments are ineffective.

Vagus Nerve Stimulation (VNS): VNS is a surgical procedure where a device is implanted under the skin that sends electrical signals to the brain via the vagus nerve. It's primarily used for treatment-resistant cases.

Lifestyle Modifications: Incorporating regular physical activity, a balanced diet, adequate sleep, and mindfulness practices like meditation and yoga can have a beneficial impact on mental health.

Complementary Therapies: These can include acupuncture, massage, and herbal supplements. However, it's essential to discuss these with a healthcare provider before starting, as some can interact with existing medications.

Remember, everyone is different, and what works for one person may not work for another. Always consult with a healthcare professional or a mental health expert when considering alternative therapies.

Seeking Support from Loved Ones and Professionals

Reaching out to loved ones and professional mental health providers can be incredibly beneficial for individuals dealing with Treatment-Resistant Depression (TRD).


The support of family and friends provides a vital network of understanding, empathy, and encouragement. Open communication about the struggles experienced can help reduce feelings of isolation and loneliness often associated with depression.


On the other hand, professional mental health support is crucial in managing TRD. Mental health professionals, such as psychologists, psychiatrists, and counselors, can provide a range of services including but not limited to diagnosis, therapy sessions, medication management, and alternative treatment options. They can also provide education about TRD and tools for coping with this challenging condition.


Support groups, both in-person and online, can also be a valuable resource for those living with TRD. These groups offer a safe space to share experiences, gain advice, and receive reassurance from individuals going through similar

experiences.


Remember, seeking help is not a sign of weakness but a step towards recovery. No one has to face Treatment-Resistant Depression alone, and there are many available options for assistance. It's important to reach out and seek the support needed to manage this condition effectively.

Conclusion

Understanding and managing Treatment-Resistant Depression (TRD) can be an arduous journey, filled with trials and challenges.


However, with the right information, support, and healthcare guidance, it's possible to navigate this terrain and improve one's quality of life. In essence, TRD is not a dead-end, but rather a call for a comprehensive, personalized

treatment approach.


From conventional medications to alternative therapies, lifestyle modifications, and support networks — there are multiple avenues to explore. And while the stigma surrounding mental health issues like TRD can seem to heighten the struggle, remember that seeking help is an act of strength.


By bringing discussions on TRD into the open, we can gradually chip away at this stigma, fostering a culture of understanding and compassion. Remember, no one is alone on this journey, and help is always available.

Spravato (esketamine) is a groundbreaking treatment for individuals with treatment-resistant depression (TRD) and major depressive disorder with suicidal ideation (MDSI). Unlike traditional antidepressants, Spravato works rapidly, often providing symptom relief within hours. In this article, we’ll introduce Spravato, discuss how long it takes to work, and explore its short- and long-term effects. What is Spravato and How Does It Work? Spravato (esketamine) is an FDA-approved nasal spray derived from ketamine, specifically designed to treat individuals with TRD and MDSI. Like ketamine, Spravato works by inhibiting NMDA receptors —proteins involved in learning and memory. This inhibition leads to the release of glutamate, a key neurotransmitter, triggering several downstream effects in brain cells. Unlike standard antidepressants, Spravato has rapid-acting effects, sometimes appearing almost immediately after use. It also offers sustained benefits compared to conventional medications and doesn’t require daily use. Short- and Long-Term Effects of Spravato on the Brain Immediate Effects Spravato enhances activity in brain regions responsible for mood regulation, which are often underactive in depression. This effect can occur within hours, often within 24 hours, leading to symptom relief and an improved mood. Long-Term Effects Over time, repeated doses of Spravato strengthen connections between nerve cells through neuroplasticity . Spravato stimulates the production of proteins that support this process, reinforcing neural circuits linked to mood and emotional regulation. Neuroplasticity may explain Spravato’s prolonged improvements in depression. How Long Does It Take for Spravato to Work? Clinical trials have shown that Spravato can quickly reduce symptoms of depression, often within hours or days. In a study of adults with TRD, those who took Spravato along with an antidepressant experienced noticeable symptom relief within 24 hours—an improvement greater than those who took a placebo with an antidepressant. Both groups continued improving over the next 28 days, but the difference between them remained significant. For people with MDSI, clinical studies have shown that Spravato, combined with an antidepressant, significantly reduces symptoms within 24 hours compared to placebo groups. The greatest differences are seen within four hours of taking the medication. Factors That Affect How Long Spravato Takes to Work The time it takes for Spravato to start working varies from person to person. Some may feel relief within hours, while others may require several treatments over days or weeks to notice significant changes. Factors that influence how quickly Spravato works include: Severity of Depression – Those with more severe symptoms may take longer to notice improvement. Individual Brain Chemistry – Differences in neurotransmitter activity can affect response time. Previous Treatments – If someone has had multiple unsuccessful treatments, their response may be slower. Overall Health – Chronic illnesses or nutritional deficiencies may impact treatment effectiveness. Psychological and Environmental Factors – Stress levels, support systems, and therapy participation can all play a role. How Long Do the Effects of Spravato Last? A single dose of Spravato provides relief for up to 24 hours, but for sustained benefits, treatment follows a structured regimen: Induction Phase Twice-weekly doses for the first four weeks. Maintenance Phase Begins after Week 4, with dosing frequency gradually reduced based on clinical response—typically shifting to once weekly or every two weeks. A long-term study found that 35.6% of patients achieved remission after the induction phase , and 46.1% remained in remission during the maintenance phase . On average, patients in the maintenance phase had used Spravato for just over three years, indicating its continued benefits with long-term use. Spravato Short-Term Side Effects While Spravato is generally well tolerated, mild side effects are common, including: Dizziness Nausea Sedation or drowsiness Dissociation (feeling detached from one’s body or reality) Increased blood pressure Anxiety or restlessness Elevated mood or euphoria These side effects typically wear off within a few hours but can linger for up to 24 hours. Safety Considerations Monitoring : Spravato is administered in a certified healthcare setting under medical supervision. Patients are monitored for at least two hours post-dose for potential side effects. Driving Restrictions : Due to possible sedation and dissociation, patients should not drive or operate heavy machinery until the following day after a full night’s rest. Potential Long-Term Risks of Spravato Ketamine is a drug of abuse with addictive properties. Chronic misuse has been linked to long-term effects such as cognitive impairment and damage to the bladder, liver, and kidneys. However, Spravato is administered in a controlled clinical environment, significantly reducing the risk of misuse . While it has not been extensively studied in patients with pre-existing substance abuse disorders, those with addiction histories may be at higher risk. Physically, Spravato appears safe for long-term use , though some evidence suggests users may experience bladder-related symptoms. However, clinical trials have found no significant difference in bladder infections between Spravato and non-Spravato patients.
