Depression and other mood disorders are common among older people and are often under-diagnosed. Depression later in life is more challenging to treat than depression in young individuals.

People with late-life depression may not respond as well to antidepressants as younger patients and may have other medical problems and take other medications that may complicate their treatment plan.
