Writing Homework Help

I’m working on a writing multi-part question and need guidance to help me learn.

Depression in later life is usually diagnosed on the basis of two clusters of symptoms: feelings and physical changes. In a 3-page paper, written in APA format using proper spelling/grammar, research the topic of depression in the elderly and address the following:

1. How would one know if an elderly relative had clinical depression or was sad because of specific life changes and losses?
2. What are the consequences of depression in the elderly?
3. Which behaviors would indicate a person going through depression needs therapy?
4. What kind of therapy would a professional recommend and why?
