A 50-year-old woman presents with mood swings, irritability, and feelings of sadness. She also reports hot flashes and irregular periods. What is the likely diagnosis and treatment approach?
The patient's symptoms suggest that she is in the perimenopause phase and might be experiencing mood changes related to hormonal fluctuations. Lifestyle changes, cognitive-behavioral therapy, and, in some cases, medication such as SSRIs or hormone therapy may be effective.
