Anxiety itself is not a mental illness. It鈥檚 a normal, adaptive emotion that helps us respond to perceived threats.
Anxiety is the automatic reaction that makes you jump back when you think you鈥檝e seen a snake while bushwalking 鈥 before realising it鈥檚 a stick.
It鈥檚 also (inconveniently) the sweaty palms and shaky voice you notice before a presentation or a first date, or the circling thoughts that keep you awake at 3am.
Most of us have ways to cope with anxious thoughts and feelings that can give us more of a sense of control. This could be checking and double-checking we鈥檝e got the room right for our presentation, or seeking reassurance from someone we love.
But when might these behaviours fit a diagnosis of an anxiety disorder? And when could they actually be a sign of obsessive compulsive disorder (OCD)?
As clinical psychologists, we find these questions come up a lot, perhaps spurred by a recent surge of interest in OCD on . So what鈥檚 the difference between anxiety and OCD? And how are they treated?
When is anxiety something more serious?
鈥淣ormal鈥 anxiety can become an anxiety disorder when fears or worry are persistent, intense and start interfering with everyday life.
About people will experience an anxiety disorder at some point in their lifetime.
Among the most common are (fear in social situations), (frequent panic attacks, and fears you鈥檒l have another) and (persistent and excessive worry).
These disorders have slightly different symptoms. But all share excessive and persistent fear or worry that causes distress or leads people to avoid important parts of life including work, study or social activities.
So, what about OCD?
Although OCD involves anxiety, it is actually considered a separate disorder in the used by mental health professionals.
It is possible to have both 鈥 around of individuals with OCD also meet criteria for one or more anxiety disorders as well.
OCD involves obsessions, compulsions, or both. These cause significant distress or interfere with daily functioning.
Obsessions are intrusive, unwanted thoughts, images or urges. This could mean an intense fear your food is contaminated, suddenly visualising hurting someone, or a feeling that keeps entering your mind that you鈥檝e made a serious mistake.
Compulsions are the repetitive behaviours (or mental rituals) people feel driven to perform to ease that distress, such as checking, repeating phrases, excessive hand-washing or seeking reassurance.
Many of us will unwanted thoughts or go back to check the oven is actually off. Keeping things tidy or being particular about routines can simply be habits that don鈥檛 cause distress.
But what makes OCD different is its severity and impact.
If obsessions or compulsions take up large amounts of time, cause you significant distress, or interfere with daily life, it may be a sign of OCD.
You can鈥檛 鈥渟pot鈥 OCD from behaviour alone. OCD can also be invisible because many compulsions happen mentally, such as repeating phrases or counting. People with OCD may also try to hide their symptoms out of shame.
Are OCD and anxiety treated differently?
While anxiety disorders and OCD share some similarities, including repetitive distressing thoughts, the patterns and beliefs driving them are different. This means the way they鈥檙e treated will also differ.
Cognitive behavioural therapy (CBT) is one of the most effective treatments for both and .
For OCD, treatment often involves a specialised form of CBT called (ERP). It involves gradually facing situations that trigger distressing thoughts while resisting the urge to perform compulsions.
For example, someone with contamination fears might gradually reduce the number of times they wash their hands before eating. Over time, people learn the feared outcome does not occur, that they can tolerate their discomfort without the ritual, and that the anxiety passes on its own.
Treatment for anxiety disorders focuses on the specific . For generalised anxiety, for example, it involves understanding patterns of worry, challenging beliefs that keep worries going, and developing more helpful ways to respond to problems, such as brainstorming solutions and taking small actions.
Antidepressant medication (particularly selective serotonin re-uptake inhibitors, or SSRIs) can be an effective component of treatment for both and . A combined treatment approach of medication (SSRIs) and therapy (CBT) often leads to the , especially for severe OCD.
A final note
