5 Ways to Ask About Hypomania

Hypomania is critical to rule out, but hard to pin down. In part 1 of this 2-part series, Dr. Aiken shares his top pearls for making the diagnosis.



"Have fun, and don’t worry about your work. As long as you don’t give an antidepressant to a patient with hypomania, you can’t go wrong.” It sounded easy at the time, as the attending welcomed us to the outpatient module of psychiatric residency. Fifteen years and over 10,000 structured interviews later, I can only attest to how hard it is to diagnose hypomania. Here are the top pearls I’ve learned along the way.

1 Calibrate your index of suspicion

Expert interviews suggest that hypomania is common among patients with depression. The rates range from 20% to 30% in primary care, 30% to 40% in psychiatric clinics, and, in those with treatment-resistant depression, 40% to 60%.1-4 Those numbers might suggest you need to raise your index of suspicion, or they may just trigger disbelief. My first reaction was the later, but when I started applying structured interviews to my work in a general adult private practice, I arrived at the same frequency: 40%.


2 Use a structured interview

Instruments like the MINI and the SCID are the closest we have to a gold standard in psychiatric diagnosis. Their hypomania sections, however, tend to suffer low reliability,5,6 so it’s helpful to augment them with paper-and-pencil screens that both the patient and a relative can complete. There are links to the SCID, MINI, and 3 screening tests (see http://www.moodtreatmentcenter.com/measurement).


3 Follow the clues

Psychologically, hypomania has a lot in common with addictions. Denial, lack of insight, and a tendency to minimize or forget these altered states get in the way of diagnosing them. When asking structured questions such as, “Have you ever had a period of time when you felt high, hyper, or full of energy?”, pay attention to vague answers like “not really,” “only when I’m excited,” or “not in a long time.” If your index of suspicion is high, those answers should prompt you to dig further.

4 Don’t explain away symptoms

Patients tend to experience mood symptoms as natural responses to life, whether depressive or hypomanic. Their explanations can leave us wondering: Was it the normal glow of romance, or did a hypomanic drive prompt that new relationship? Was it just an all-nighter during final exams in May, or springtime hypomania? Was it youthful folly, or did bipolar strike at the usual age of onset (15 to 20)? I have never found definitive answers to those questions, but ambiguous answers remind me to keep looking for clues as I get to know the patient better.


5 Comorbidities are a soft sign of bipolar, not a reason to dismiss it

All the symptoms of hypomania are common in other disorders:

ADHD: hyper, distracted, racing thoughts, talkative, impulsive

Borderline personality disorder: labile, impulsive, irritable

PTSD: irritable, reckless behavior

OCD: hyperactive around compulsions

GAD: racing thoughts, distracted, irritable

Addictions: impulsive, euphoric, decreased need for sleep


The problem is that 60% of patients with bipolar disorder have at least one of the comorbidities I just listed, so their presence should raise-not lower-the index of suspicion.7

Uncertainty is the rule with hypomania. I’ve followed some patients for 10 years before recognizing it. It’s humbling work, not unlike the type of dilemma Hippocrates wrestled with when he wrote that “Life is short; the art is long; opportunity fleeting; experience perilous; and decision difficult.”8 Tune in next month for part two of this guide, and never stop looking for clues.
