The condition
Depression is common. It causes feelings of sadness, despair, hopelessness, and guilt or low self‑worth, as well as tiredness, lack of interest in life and difficulty concentrating. People with severe depression may be unable to eat or sleep, or to take part in social activities, may become completely withdrawn and may have suicidal thoughts. The condition can last from weeks to years, and can recur.
Treatments for depression include psychological (talking) therapies and antidepressant medicines. In severe depression that has not improved with other treatments, electroconvulsive therapy (ECT) is sometimes used. ECT is used with a general anaesthetic. It involves applying an electric current to the brain so strong that it causes seizures (fits) and sometimes memory loss.
NICE has looked at using transcranial direct current stimulation as another treatment option. NHS Choices (www.nhs.uk) and NICE's information for the public about depression.
