DMDD is marked by frequent, intense temper tantrums that interfere with a child's ability to function at home, in school or with friends. Some of the kids now diagnosed with DMDD have previously been diagnosed as bipolar, even though they usually don't have all of the traditional signs and symptoms of that disorder.
Kids with DMDD usually don't develop bipolar disorder in adulthood. They're more likely to acquire problems with depression and/or anxiety, though.
Here's a list of the symptoms of DMDD:
- Severe temper outbursts at least three times a week
- Sad, irritable or angry mood almost every day
- Reaction is bigger than expected
- Child must be at least six years old
- Symptoms begin before age ten
- Symptoms are present for at least a year
- Child has trouble functioning in more than one place (e.g., home, school and/or with friends)
So, that's what it is.
