ANNOUNCER: Today sleeping medications may fall into several categories. One is benzodiazepines.
ARTHUR SPIELMAN, PhD: They're very effective. They don't lose their effectiveness over time; they're a very good class of drugs.
The side effects for benzodiazepines are grogginess in the morning, memory problems.
ANNOUNCER: Another solution is non-benzodiazepines.
ARTHUR SPIELMAN, PhD: Some are very short-acting, and so you can wake up in the morning not feel that hangover. But then again, some patients feel that they don't get enough sleep on them because they're not long enough-acting. If you take enough of these non-benzodiazepines, it'll affect memory.
And then the antidepressants. There are some sedating antidepressant drugs that are useful for sleep and are used commonly.
ANNOUNCER: But even when the depression starts lifting, the insomnia may remain.
ARTHUR SPIELMAN, PhD: Insomnia can take on a life of its own once it's started. So you may have to address insomnia independently, even after you're not depressed.
ANNOUNCER: So while depression is serious, experts suggest that solving sleep problems is also important. Good sleep can contribute not only to a restful night, but also to a much better day.
JAMES O'BRIEN, MD: It's extremely important for patients who have depression to handle and address any underlying sleep problem that may be occurring.
