Bipolar disorder in men and women: what’s the difference?


Did you know that 46 million people worldwide are living with bipolar disorder?

This breaks down to a slightly uneven split of 48% male 52% female, and this pattern is seen in almost all countries1.

But are there other ways in which bipolar disorder differs between males and females, and do they really change how males should be treated?

Before we continue, here’s a quick reminder on the main subtypes of bipolar disorder:

Bipolar I is characterized by at least one episode of mania that affects functioning.

Bipolar II is characterized by at least one episode of hypomania (a briefer and less severe form of mania) plus at least one episode of major depression.

Rapid cycling is characterized by at least four episodes of mania, hypomania, depressive or mixed episodes in any 12-month period.

Which subtypes of bipolar disorder are men more likely to have?

Many papers have been written on this controversial topic, but this article (based on various studies) should help to clarify some of the data.

  • Bipolar I is seen more in men than women
  • Bipolar II is seen less often in men than women2

Do men present with different symptoms compared to women?

According to the results of multiple studies:

What’s the relevance of conduct disorder and substance abuse in men?

Conduct disorder is a clinical definition, which can be characterized as “a repetitive and persistent pattern of behavior in which the basic rights of others or major age-appropriate societal norms or rules are violated.” The person diagnosed with conduct disorder has to have met at least three criteria in the past 12 months, which may include bullying or threatening behaviour, use of a weapon, stealing from someone’s person and so on6.

There can be a misperception in the general public and media that people with bipolar disorder, especially men, are physically aggressive and dangerous. The real story is that although there is an increased risk of aggression in men with bipolar disorder this generally only applies to those who have substance abuse problems, that is, those who have addiction problems with tobacco, alcohol or other drugs7.

As well as affecting behavior towards others, we can also see from research that substance abuse, as well as male gender, and younger age of onset are also associated with not sticking with a treatment plan4.

Suicide risk

Worryingly, researchers in 2011 suggested that 8% of men and 5% of women with bipolar disorder died from suicide8.

The next logical question is why is there a difference between the figures for men and women? If we could understand the story behind these figures, then surely we can save lives. Here are some points we could consider as relevant:

  • We know substance abuse is more common in men. Substance abuse means a slower recovery from bipolar disorder episodes and increased suicidal ideation.
  • Substance abuse means the person is less likely to stick with taking medications9
  • Being male is a risk factor by itself10. Research continues to find out why
  • A Spanish study showed men to be less adherent to treatment than women, possibly related to higher substance abuse rates in men4
  • In a New Zealand study of people with bipolar disorder under specialist care, researchers found that men were more likely than women to have substance use disorder, were more likely to be convicted for crimes when unwell, and were also more likely to receive compulsory treatment orders and inpatient treatment11
  • Another study based in Sweden showed that women were as likely as men to take the initiative to stop lithium, but twice as likely to consult a doctor before taking action12 (reasons might include perceived lack of effectiveness or side effects). This is a particularly concerning finding when lithium is just as effective for men as it is for women2, and because lithium is still the gold standard treatment for bipolar disorder and the only medication proven to reduce the risk of suicide13

Take-home messages

Let’s work with what we can have some control over.

  1. Substance abuse is seen more frequently in men than women. It reduces speed of recovery, reduces ability to stick to a medication regime, and increases suicide risk. Not only that, but stimulants (like amphetamines and cocaine) may induce mania and consequent risky, dangerous behaviours; and depressants like alcohol and benzodiazepines can trigger or exacerbate depression14. If substances might be affecting your mental health, get help.
  2. Thinking about stopping medication is not unusual in anyone taking long-term treatment, but if you feel that you no longer need to take a drug, see your doctor first to discuss things further.
  3. Learn more about what the warning signs are when you are starting to head towards a relapse. [LINK HERE TO OTHER ARTICLE ON “WARNING SIGNS”?]
  4. Seek help and support from trusted people when you need it. Stigma is a complex and strange beast, whether it comes from society or our culture, or even ourselves. Not having compassion for ourselves can get in the way of seeking help, worsening mental health, and then we could get caught in a vicious cycle. Don’t let stigma be a barrier to living life well15,16
  5. Follow a healthy lifestyle, including a good routine and sleep pattern; reduce stressors where you can. Do things that make you happy
