Signs of mild depression may also include a gloomy mood, an inability to feel joy, a sorrowful facial expression, and often downturned corners of the mouth. The head may be tilted forward with a downward gaze, and there might be fewer changes in posture. Patients may experience sleep disturbances, commonly having trouble falling asleep, waking repeatedly at night, and still being in the sleep process when waking up in the morning. Appetite reduction may not be very noticeable. Mood variations occur during the day, often with a worse mood in the evening compared to the morning. There is no significant slowing down of movement, but the emotional state of the patient is often poor. Some patients may experience symptoms of autonomic nervous system dysfunction, such as dizziness, headaches, and bodily discomfort, which are indicative of mild depression.
