Our state of mind constantly changes and is an indicator of how we feel and how we interact with the other people. In general, we usually describe our states of mind using al lot of adjectives, popular metaphors or symbols which express the different and abstract ways in which they are felt by each person: "I feel concerned", "I feel down" and so on. In this section, we will present a brief list and description of the disorders related with states of mind.
Depression: it is the best known disorder, and is unfortunately is increasingly spreading and prevailing. There are many factors which make depression more or less serious for the person suffering from it — personal, cultural, genetic, and gender features, among others. We talk of Major depression disorder when referring to a depression episode during which the patient feels dejection and sadness most of the time, without being able to enjoy doing activities, and which is characterised by low self-esteem and recurring insomnia. On the other hand, we talk of dysthymic disorder when depression extends over time and becomes chronic. Moreover, it generates serious sleeping alterations, and irritability and dejection increase to such a point that the depressed person is never able to "feel whole". Recurring thoughts about wanting to disappear and suicide attempts are also very frequent.
Manias: people suffering from this disorder are constantly very nervous and excessively euphoric. They are very expansive and feel almost invincible, even if they must carry out normal, ordinary actions. This state may become so extreme to provoke delirium or hallucinations.
Bipolar disorder: as its very name indicates – bi means double – this disorder implies switching from one state to another very easily, the one being a serious depressive state and the other being a maniacal state, both brought to an extreme level. People who suffer from this disorder tend not to be able to control their feelings, so as to find themselves in situations which might be very dangerous both for themselves and for the people around them. The disorder is divided into Bipolar disorder I and II, according to the frequency of the bipolar episodes.
