Defining anxiety and anxiety disorders

Anxiety can be defined as a state of tension, nervousness and apprehension. It may be related to external events, or there can be no obvious cause at all. It can manifest in many forms and can affect people in different ways.

It has been pointed out (such as in this paper from Oxford University Press) that anxiety, as related to fear, may a normal evolutionary reaction that can help keep us safe.

If tension, nervousness and apprehension persist for prolonged periods, or if your feelings and responses interfere in some way with your normal life, it may be considered an “anxiety disorder”, which has more specific definitions.

What are the different types of anxiety disorders?

Anxiety can manifest in different forms and affect people in different ways. The National Institute of Mental Health lists a number of distinct (but related) forms of anxiety disorder:

  • Generalised anxiety disorder
  • Panic disorder
  • Social anxiety disorder
  • Phobias
  • Separation Anxiety Disorder
  • Obsessive-compulsive disorder

We will go into more detail about the meanings of each, describing their particular traits and symptoms, in the next section.

Does anxiety cause panic attacks? What is the connection?

Panic and anxiety are closely related. The NHS describes panic as “the most severe form of anxiety”. Not everyone who suffers from anxiety will suffer from panic or panic attacks. For those that do, it can be very distressing, with an attack developing rapidly and without warning.

Why do we develop anxiety disorders? What are the root causes?

There are many causes for anxiety disorders. Anxiety disorders could occur in those with a family history of mental health difficulties. Those with a personality prone to worrying could be at risk of developing a full-blown anxiety disorder at some point in their life. Being subjected to constant stress and worry regularly could contribute to the development of anxiety disorders. The repeated use of illicit drugs and stimulants like caffeine can also increase the risk of developing anxiety. Certain medical conditions are known to be associated with the symptoms of anxiety and this should be ruled out by your doctor before proceeding with a treatment plan.

What can I do to avoid anxiety disorders?

There are certain things that we can all do reduce our risk of developing an anxiety disorder:

  • Finding time to relax and meditate
  • Reduce stress levels by managing workload and breaking down tasks
  • Avoid constant and unsustainable stress-provoking environments and situations
  • Optimise nutrition by eating healthy and drinking adequate amounts of water
  • Avoid unhealthy foods and drinks
  • Minimise intake of caffeine, nicotine and energy drinks
  • Adequate sleep and exercise
  • Spending time doing the things you enjoy and keeping the right company
  • Avoid news channels

How are anxiety disorders treated? Where can I go to get treatment?



There are different treatments for anxiety disorders depending on the nature and severity of the condition.

Mild to moderate anxiety:

These symptoms respond well to psychotherapeutic and behavioural therapies and this is usually the first-line treatment.

All of these treatments can be administered by an appropriately trained therapist.

Severe forms of anxiety:
Where the above symptoms may require medication, which we talk about in more detail below.

Are there medications that help with anxiety?


More severe forms of anxiety may require medications such as anti-depressants or benzodiazepines.

Your doctor or therapist will perform tests and investigations to rule out a medical reason for your anxiety and will devise a treatment plan based on the nature and severity of your symptoms.

Often, the first medication a doctor will prescribe will be one that slows the reabsorption of the hormone serotonin. Serotonin helps stabilise mood. By blocking serotonin from being reabsorbed by the cell that created it, more serotonin will remain at work for longer in the brain. For this reason, these drugs are called Selective Serotonin Reuptake Inhibitors, or SSRIs.

Though often effective, if the SSRI is not having the desired effect other drugs may be prescribed by the patient’s GP.
