Cyclothymia
Cyclothymia, or cyclothymic disorder, causes mood changes – from feeling low to emotional highs.
Cyclothymia is a mild form of bipolar disorder.
Most people's symptoms are mild enough that they do not seek mental health treatment, or the emotional highs feel nice, so they do not realise there's anything wrong or want to seek help.
This means cyclothymia often goes undiagnosed and untreated.
But the mood swings can affect daily life, and cause problems with personal and work relationships.
If you think you have cyclothymia, it's important to seek help from a GP.
People with cyclothymia are at risk of developing full bipolar disorder, so it's important to get help before reaching this stage.
People can get cyclothymia at any age.
Symptoms of cyclothymia
If you have cyclothymia, you'll have periods of feeling low followed by periods of feeling very happy and excited (called hypomania) when you do not need much sleep, are more sociable and impulsive and feel that you have a lot of energy.
The periods of low mood do not last long enough and are not severe enough to be diagnosed as depression.
You might feel sluggish and lose interest in things during these periods, but this should not stop you going about your day-to-day life.
Mood swings will be fairly frequent – you will not go for longer than 2 months without experiencing low mood or an emotional high.
Doctors may diagnose cyclothymia if you've had symptoms for at least 2 years, or 1 year for children and teenagers.
Symptoms of cyclothymia are not severe enough for you to be diagnosed with full bipolar disorder, and your mood swings will be broken up by periods of normal mood.
Treatment for cyclothymia
Treatment usually involves some kind of talking therapy (psychotherapy). You may also need medicines.
The aim is to:
- stop the cyclothymia developing into full bipolar disorder
- reduce your symptoms
- stop your symptoms coming back
Psychotherapy
Psychotherapy, such as cognitive behavioural therapy (CBT), may help with cyclothymia.
CBT involves talking to a trained therapist to find ways to help you manage your symptoms by changing the way you think and behave.
You'll be given practical ways to improve your state of mind on a daily basis.
Medicines
You may be prescribed medicines to level out your mood (mood stabilisers).
Mood stabilisers include:
- lithium – commonly used to treat bipolar disorder
- epilepsy medicines – such as carbamazepine, oxcarbazepine or sodium valproate
Some antipsychotics such as quetiapine are also sometimes used as mood stabilisers.
But not all people with cyclothymia need or respond to medicine.
The charity Mind has more information on lithium and other mood stabilisers.
Further support for cyclothymia

Living with cyclothymia
It's not known how many people with cyclothymia will go on to develop full bipolar disorder.
But some people with cyclothymia see their elevated or depressed moods become more severe.
Other people will find their cyclothymia continues and they need to manage this as a lifelong condition.
Causes of cyclothymia
The causes of cyclothymia are not known, but there's probably a genetic link because cyclothymia, depression and bipolar disorder all tend to run in families.
In some people, traumatic events or experiences may act as a trigger for the condition, such as severe illness or long periods of stress.
