About Anxiety and Depression
Approximately 25% of people in the UK will suffer from a mental health problem each year. The majority of these cases are anxiety or depression. The World Health Organisation estimates that by 2030 depression will be the leading cause of disability in the world. Anxiety and depression can be vary dramatically in effects and duration with some getting debilitating of not dealt with. They can come with a mix of other symptoms including; insomnia, irritability, poor concentration, sweating, nausea, diarrhoea, palpitations, aches and pains, shortness of breath, lassitude, low self-esteem, irritable bowel syndrome, headaches and migraines and even suicidal thoughts.
Stressful events often trigger anxiety and depression, such as; bereavement, illness, relationship problems or financial difficulties. Anxiety and depression can also come secondary to another to chronic illness, such as cancer, or other conditions, including, insomnia and chronic pain.
There tend to be two types of treatment approaches for anxiety and depression, namely drugs or therapy. The former has mixed results in both the short-term and long-term and can result in a variety of side-effects including; drowsiness, dizziness, slurred speech, trouble concentrating. Long term use can lead to addiction and neurotoxicity. The later, therapy can have good results in the long term if the condition is a result of psychological trauma, however, it can take a while to build up such effects and is not always as useful if the anxiety or depression is secondary to physical conditions such as chronic pain or chronic illnesses.
Acupuncture for anxiety and depression
Acupuncture has no long-term risks associated with it and has been shown, in a range of studies, to be safe. Acupuncture has also been shown to be beneficial for anxiety and depression. The World Health Organisation recommends acupuncture for depression and the more up to date, comprehensive review of acupuncture, from The Acupuncture Evidence Project recommends acupuncture for anxiety.
A systematic review for anxiety stated, ‘that acupuncture was an effective alternative therapy for generalized anxiety’ (Rui et al. 2016). It also noted acupuncture was as effective as drugs and safe. In the largest ever study conducted into acupuncture, The York study, acupuncture was found to clinically effective, safe and cost-effective for depression.
There are also preliminary positive findings for treating chronic anxiety associated with post-traumatic stress disorder, substance misuse, eating disorders, hyperventilation, asthma, insomnia, post-stroke, musculo-skeletal pain and various other conditions where anxiety has been measured as a secondary rather than primary issue.
How does acupuncture benefit anxiety and depression?
Research has shown that acupuncture treatment may benefit anxiety and depression by:
- Acting on areas of the brain known to reduce sensitivity to pain and stress, as well as promoting relaxation and deactivating the ‘analytical’ brain, which is responsible for anxiety and worry (Hui, 2010)
- Regulating levels of neurotransmitters (or their modulators) and hormones such as serotonin, noradrenaline, dopamine, GABA, neuropeptide Y and ACTH; hence altering the brain’s mood chemistry to help to combat negative affective states (Lee 2009; Samuels 2008; Zhou 2008; Yuan 2007)
- Stimulating production of endogenous opioids that affect the autonomic nervous system. Stress activates the sympathetic nervous system, while acupuncture can activate the opposing parasympathetic nervous system, which initiates the relaxation response. (Arranz 2007)
- Reversing pathological changes in levels of inflammatory cytokines that are associated with anxiety and depression (Arranz 2007)
- Reversing stress-induced changes in behaviour and biochemistry (Kim 2009)
- Some of the most recent research suggests that depression is associated with dysfunction in the way that parts of the resting brain interact with each other; acupuncture has been shown to be capable of changing the ‘default mode network’ (Dhond 2007)
Acupuncture can be safely combined with conventional treatments such as medication or psycho-educational therapy, possibly enhancing their beneficial effects and reducing unwanted side-effects. (Courbasson 2007 and Yuan 2007).
