From the Guidelines
It is highly unlikely to have depression without experiencing any of the common symptoms such as numbness, anhedonia, low libido, fatigue, guilt, shame, low self-worth, boredom, family history, sleep issues, or childhood trauma, as these are key diagnostic criteria for depression. According to the American Psychiatric Association, depression is defined as depressed mood or loss of pleasure or interest along with other symptoms, including significant change in weight or appetite, insomnia or hypersomnia, psychomotor agitation or retardation nearly every day, fatigue or loss of energy, feelings of worthlessness or excessive or inappropriate guilt, indecisiveness or decreased ability to concentrate, and recurrent thoughts of death or suicide, that last for at least 2 weeks and affect normal functioning 1. The Patient Health Questionnaire-9 (PHQ-9) is a commonly used tool to screen for depression, and it assesses symptoms such as sleep problems, low energy, appetite, low self-view, concentration difficulties, motor retardation or agitation, and thoughts of self-harm 1.
Some key points to consider in the diagnosis of depression include:
- The presence of at least five symptoms for at least two weeks, including either depressed mood or loss of interest/pleasure (anhedonia) 1
- The impact of symptoms on daily functioning and overall well-being 1
- The use of screening tools such as the PHQ-9 to assess symptom severity and monitor treatment response 1
- The importance of consulting with a mental health professional for an accurate diagnosis and treatment plan, as depression exists on a spectrum and presentations can vary significantly between individuals 1
In the absence of many core symptoms, it is possible that the individual may be experiencing a different mental health condition, such as adjustment disorder, grief, or a specific type of depression like atypical depression. A comprehensive diagnostic evaluation by a mental health professional is necessary to determine the underlying condition and develop an effective treatment plan.
From the Research
Depression Symptoms and Treatment
- Depression is a complex condition with various symptoms, and it is possible for individuals to experience depression without exhibiting all common symptoms such as numbness, anhedonia, low libido, fatigue, guilt, shame, low self-worth, boredom, family history, sleep issues, or childhood trauma 2.
- The symptoms of depression can vary widely among individuals, and treatment should be tailored to each person's specific needs 3, 4.
- Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used to treat depression, and they have different pharmacological characteristics and side effect profiles 5, 6.
Treatment Options
- SSRIs are a group of structurally unrelated molecules that share a similar mechanism of action, but each has unique pharmacokinetics, pharmacodynamics, and side effects 4.
- SNRIs, such as venlafaxine, duloxetine, and milnacipran, block the reuptake of both serotonin and norepinephrine with differing selectivity, and they have been shown to be efficacious in treating depression and anxiety disorders 3, 5.
- The choice of treatment should be based on a risk-benefit analysis, taking into account the potential treatment effects, adverse effects, and dangers of the illness to be treated 4.
Individual Variability
- Individuals may respond differently to various treatments, and it is essential to monitor their response and adjust the treatment plan as needed 2, 3.
- The dosage and administration of SSRIs and SNRIs can vary depending on the specific medication and the individual's needs, and it is crucial to follow the recommended guidelines to minimize adverse effects 5, 6.
