You’ve recognized the pattern—winter after winter of the same exhaustion, low mood, and difficulty functioning. You’ve decided to seek professional help. Now comes the uncertainty: What will they ask? What tests will they run? How do you prepare? A comprehensive seasonal affective disorder evaluation typically includes a physical exam with in-depth health questions, laboratory tests to rule out conditions that mimic depression such as thyroid dysfunction or vitamin D deficiency, and a psychological evaluation exploring your symptoms, thought patterns, and behavior changes across seasons. The diagnostic process requires documenting at least two consecutive years of winter depressive episodes with full remission in spring or summer, plus evidence that seasonal episodes significantly outnumber any non-seasonal mood episodes throughout your lifetime (Melrose, 2015).
Understanding what happens during your first appointment reduces anxiety and helps you prepare effectively. While specific evaluation approaches vary between providers, the core elements remain consistent: gathering a detailed history, ruling out medical causes, and determining whether your experience meets criteria for seasonal affective disorder versus other conditions.
Before Your Appointment: What to Prepare
Symptom timeline documentation. Create a simple timeline of the past 2-3 years noting when symptoms began each fall/winter, how severe they became, and when they resolved in spring/summer. Include specific symptoms you experienced: changes in sleep, appetite, energy, mood, concentration, and social withdrawal. The more specific you can be—”typically starts mid-November, improves by late March”—the more useful this information becomes.
Previous treatment history. List any treatments you’ve tried for seasonal depression or depression generally: medications (names and doses), therapy (type and duration), light therapy (device specifications and usage pattern), supplements. Note what helped, what didn’t, and any side effects you experienced. If you stopped treatments, explain why—did symptoms improve, did side effects become intolerable, or did the treatment simply not work?
Current medications and supplements. Bring a complete list including prescription medications, over-the-counter drugs, vitamins, and herbal supplements with dosages. Some medications can affect mood or interact with depression treatments. Seemingly unrelated medications sometimes provide important diagnostic clues.
Family history information. Document any family members who’ve experienced depression, bipolar disorder, seasonal affective disorder, or other mental health conditions. Genetic factors play a role in mood disorders, and family history influences treatment considerations, particularly the choice between antidepressants and other approaches.
Questions you want answered. Write down your questions beforehand. When you’re anxious during an appointment, it’s easy to forget what you wanted to ask. Common questions include: What’s causing my symptoms? What treatment options exist? How long until treatment works? What are the costs? How often will I need appointments?
The Physical Examination Component
Even though seasonal depression is a psychiatric condition, a physical exam remains essential. Several medical conditions can cause or worsen symptoms that look like seasonal depression.
General health assessment. Your provider will check vital signs—blood pressure, heart rate, temperature—and perform a basic physical exam. They’re looking for signs of medical conditions that might contribute to depression: thyroid enlargement suggesting thyroid dysfunction, pallor indicating possible anemia, or other physical findings that warrant further investigation.
Questions about your health history. Expect detailed questions about medical conditions, surgeries, hospitalizations, allergies, and current physical symptoms. Be honest about substance use—alcohol, recreational drugs, tobacco—as these significantly affect treatment planning. Your provider needs accurate information to recommend safe, effective treatment.
Laboratory testing. Most providers order blood tests before starting depression treatment. A complete blood count checks for anemia. Thyroid function tests (TSH, potentially T3 and T4) rule out hypothyroidism, which commonly causes fatigue and low mood. Vitamin D levels are often checked, as deficiency is common in Idaho winters and contributes to depression symptoms. Some providers also check vitamin B12, folate, or comprehensive metabolic panels.
These tests serve two purposes: identifying treatable medical causes of your symptoms and establishing baseline values before starting medications. For example, some antidepressants can affect thyroid function or liver enzymes, so baseline values provide comparison points if questions arise during treatment.
At Boise Ketamine Clinic, our evaluation process begins with a 15-minute phone consultation at (208) 427-8596 where we discuss your history and determine whether our specialized treatment approach might be appropriate. If ketamine therapy seems suitable, we conduct comprehensive medical screening to ensure safety. Our founder, Nykol Bailey Rice, brings both CRNA and PMHNP credentials with over eight years of specialized experience evaluating complex, treatment-resistant depression cases.
The Psychological Evaluation Process
This portion explores your emotional experience, thought patterns, and behavioral changes in detail. Providers need specific information to distinguish seasonal affective disorder from other conditions and determine appropriate treatment.
Depression symptom inventory. Your provider will ask about the nine core depression symptoms: depressed mood, loss of interest or pleasure, significant weight or appetite changes, sleep disturbances, psychomotor agitation or retardation, fatigue, feelings of worthlessness or guilt, difficulty concentrating, and thoughts of death or suicide. For each symptom, they’ll want to know severity, duration, and seasonal pattern.
Seasonal affective disorder involves specific symptom patterns—the “atypical” features like increased sleep rather than insomnia, increased appetite rather than loss of appetite, carbohydrate craving, and weight gain. Your provider will specifically ask about these seasonal patterns.
Seasonal pattern documentation. This is the crucial diagnostic element for SAD. Your provider needs to establish that your depressive episodes occur at specific times of year with full remission at other times. They’ll ask: When do symptoms typically begin? When do they end? Has this pattern repeated for at least two consecutive years? Do you experience depression during other times of year, or only during fall/winter?
The Seasonal Pattern Assessment Questionnaire (SPAQ) is sometimes used, though it’s more common in research settings than clinical practice. This self-report measure asks about seasonal variations in sleep, appetite, weight, energy, mood, and social activity. However, diagnosis relies primarily on clinical interview and DSM-5 criteria rather than screening tools alone (Galima et al., 2020).
Functional impairment assessment. How does seasonal depression affect your life? Your provider needs to understand whether symptoms merely cause discomfort or actually impair your ability to work, maintain relationships, or care for yourself. This information influences treatment intensity—mild symptoms might warrant light therapy alone, while severe impairment suggests more aggressive intervention.
Suicide risk evaluation. Every depression evaluation includes questions about suicidal thoughts, plans, or past attempts. These questions aren’t asked because your provider thinks you’re imminently suicidal—they’re standard protocol for anyone experiencing depression. Answer honestly. If you’re having thoughts of self-harm, your provider needs to know to ensure you receive appropriate, immediate care.
Co-occurring conditions. Your provider will ask about anxiety, panic attacks, obsessive thoughts, trauma history, eating patterns, and substance use. Seasonal depression often co-occurs with anxiety disorders, and treatment planning must address all relevant conditions. Trauma history is particularly important because it influences both diagnosis and treatment selection.
Distinguishing SAD from Similar Conditions
Several conditions can be confused with seasonal affective disorder, and part of your evaluation involves ruling these out.
Bipolar disorder with seasonal pattern. Some people with bipolar disorder experience depressive episodes primarily in winter and hypomanic or manic episodes in summer. This isn’t seasonal affective disorder—it’s bipolar disorder with a seasonal pattern. The distinction matters enormously because treatment differs. Antidepressants can trigger manic episodes in people with bipolar disorder, while mood stabilizers or atypical antipsychotics might be needed. Your provider will ask about any history of unusually elevated mood, decreased need for sleep while feeling energetic, impulsive behavior, or racing thoughts.
Hypothyroidism. Low thyroid function causes fatigue, weight gain, cold intolerance, dry skin, hair loss, constipation, and depression—a symptom cluster that can look remarkably like seasonal affective disorder. Blood tests distinguish the two conditions. If hypothyroidism is present, treating it often resolves the depressive symptoms without requiring depression-specific treatment.
Vitamin D deficiency. Living in Boise at 43°N latitude means your skin can’t synthesize vitamin D from November through February regardless of sun exposure. Severe vitamin D deficiency causes fatigue, bone pain, muscle weakness, and mood changes. While the relationship between vitamin D and depression is complex, checking levels and treating deficiency is standard practice.
Chronic fatigue syndrome or fibromyalgia. These conditions involve severe fatigue, cognitive difficulties, and often worsen in winter. Your provider will ask about pain patterns, post-exertional malaise, and other features that distinguish these conditions from seasonal depression.
What Happens After the Evaluation
At the end of your appointment, your provider should explain their diagnostic impression and recommend treatment options. For seasonal affective disorder, this typically involves discussing light therapy, cognitive-behavioral therapy, antidepressant medications, or some combination.
Treatment recommendations should be collaborative. Your provider presents options with evidence for effectiveness, potential benefits, risks, and practical considerations. You discuss your preferences, concerns about cost or time commitment, and previous treatment experiences. Together, you develop a treatment plan that makes sense for your situation.
Some providers prescribe treatment immediately at the first appointment. Others prefer waiting for laboratory results before starting medication. If you’re starting light therapy, you might receive specific instructions about timing, duration, and light box specifications.
Follow-up planning. Your provider should schedule follow-up to assess treatment response. For light therapy, this might be 2-4 weeks. For antidepressants, typically 4-6 weeks to allow time for medication to take effect. These follow-ups aren’t optional—they’re how your provider monitors whether treatment is working and adjusts the approach if needed.
Cost and Practical Considerations
What to ask about cost. Before leaving your appointment, clarify: What are the charges for the evaluation? What do follow-up visits cost? If medication is prescribed, what’s the typical monthly cost? Is the treatment covered by insurance? What are self-pay options?
At Boise Ketamine Clinic, we’re transparent about our hybrid cash-and-insurance model. While we accept some insurance plans (Spravato is often reimbursed), most ketamine infusions are private pay. We discuss costs clearly during the free consultation so there are no surprises. Our comprehensive treatment series includes preparation sessions, therapy-guided ketamine sessions with a prescriber, registered nurse, and therapist all present, and integration work spanning 5-7 hours total.
Scheduling flexibility matters. Ask about appointment availability. Do they offer evening or weekend appointments? This is particularly important if work schedule makes traditional business-hours appointments difficult. We offer Saturday appointments and flexible scheduling Monday through Saturday, typically 10am-6pm, at our West Overland Road location in Boise.
Timeline expectations. Ask how long until you should expect improvement and what to do if treatment isn’t working. Knowing that light therapy typically shows benefit within 1-2 weeks while antidepressants need 2-4 weeks helps you maintain realistic expectations rather than giving up prematurely.
Three Practical Steps You Can Take This Week
- Call to schedule rather than waiting. The hardest part of seeking treatment is often making the initial phone call. If you’ve recognized a pattern of winter depression for two or more years, call this week. Don’t wait until you’re already deeply depressed and struggling to function. Many practices have waiting lists, so calling when you’re still feeling okay ensures you can get an appointment before symptoms become severe.
- Gather your documentation. Spend 30 minutes this week creating that symptom timeline, listing previous treatments, compiling current medications, and writing down questions. Having this information organized makes your appointment more productive and ensures you don’t forget important details.
- Identify your support person. Consider bringing someone to your appointment—a partner, family member, or friend. They can help you remember information discussed, provide additional history if you forget details, and offer support. If that’s not possible, plan to take notes or ask if you can record the session (with permission) so you can review recommendations later.
What If You Feel Worse Before Your Appointment?
If you’ve scheduled an appointment for two weeks from now but your symptoms are rapidly worsening, don’t wait. Call the office to explain the situation and ask about earlier availability. If you’re experiencing thoughts of self-harm or suicide, call 988 (Suicide & Crisis Lifeline) or go to your nearest emergency room immediately—Boise has emergency psychiatric services at both St. Luke’s and Saint Alphonsus hospitals.
Seasonal depression evaluation shouldn’t feel like an interrogation or judgment. A good provider creates a collaborative atmosphere where you feel heard and understood. They should explain their diagnostic thinking, present treatment options clearly, and respect your input in treatment planning.
You’ve already taken the hardest step by recognizing you need help. The evaluation itself is simply gathering the information needed to provide that help effectively. Walking into an appointment prepared with documentation and questions transforms anxiety into productive collaboration. Your seasonal depression has a pattern, and patterns can be disrupted with the right treatment approach tailored to your specific situation.
