More than a passing low mood

Depression can affect mood, motivation, sleep, concentration, relationships, and physical well-being. It is a medical condition, not a failure of willpower. People experience it differently; some notice irritability or loss of interest more than sadness.

When to seek an evaluation

Symptoms present much of the time for two weeks or longer deserve attention, especially when they affect daily activities. You can seek help sooner if symptoms are distressing. A qualified clinician considers your history and other explanations, including medical conditions, medications, and bipolar mood episodes.

Understanding your treatment options

Psychotherapy, medication, and supportive daily routines can all play a role. When depression has not improved sufficiently, further evaluation may include medication adjustments, augmentation, TMS, or other treatments. The plan should reflect your diagnosis, preferences, prior response, and safety considerations.

Screening helps start a conversation

The PHQ-9 measures depressive symptoms over the previous two weeks. Its score helps describe severity and track change, but does not independently diagnose depression or determine TMS eligibility.
