Anhedonia, When "Nothing Feels Good" Isn't Just One Thing
If depression has taken the enjoyment out of your life, you already know it's one of the hardest parts to describe. Sadness has words. This doesn't. Food isn’t as interesting. Friends text and you don't answer, not because you're upset with them but because you can't imagine the visit being worth it. The hobby that used to absorb you sits untouched in a closet.
Clinicians have a name for it anhedonia and for a long time we've treated it as a single thing you either have or don't. A new study suggests that's a mistake, and that the details of what you've stopped enjoying may carry useful information.
Four different kinds of "nothing"
Researchers in Canada followed 187 adults going through a major depressive episode. Before anyone started treatment, each person filled out questionnaires about enjoyment in four separate areas: hobbies and activities, food, being around other people, and sensory experiences, a hot shower, a good smell, music, the look of a sunset.
Everyone took escitalopram, a common antidepressant, for eight weeks. For the 90 people who hadn't improved enough, a second medication called aripiprazole, which works on dopamine, was added for another eight weeks.
The four areas didn't behave the same way. People who'd lost sensory pleasure going in tended to respond less well to the first medication. People who'd lost pleasure in food and in other people tended to respond less well when the second one was added. A single overall score for "how much enjoyment have you lost" predicted less than the four separate areas did which is really the finding. Averaging it all into one number throws away something.
How much should you make of this?
Honestly, not a lot yet, and the researchers would agree. Everyone in the study got the same two medications in the same order, with no comparison group receiving something different. So the study can show that certain symptoms come with tougher outcomes, but it can't tell us that a different drug would have worked better. The differences were also small, a point or two on a 60-point depression scale. Part of the finding didn't survive the researchers' own statistical checks, and one of the measurements they relied on had never been tested before.
What to do with it
Nothing here is a test to ask for, and nothing here is a reason to change the medication you're on. What it is, is a reason to be specific at your next visit.
If enjoyment has gone flat, try to say where. Is it food? People? Music, texture, being outside? Doing things at all? It's a small distinction that's easy to skip when an appointment is short and it may turn out to matter more than a number ever could.
