During maintenance treatment to prevent relapses, patients are monitored for at least six months after the symptoms of the disorder have regressed. Longterm therapy is all the more important the more frequent the depressive phases in the past and the more severe they have been. In other words, patients are therapeutically monitored beyond the maintenance treatment period. This guide is based on the latest research findings and should improve your understanding of the illness “depression”. It is aimed at those affected, their family members and friends and interested parties in equal measure. This guide is not a substitute for personalised medical advice and diagnosis, but may help to stimulate more indepth discussion. Depressive disorders are amongst the most severe and important illnesses globally. Up to 20 of people are affected by them in their various forms. They affect a person’s thoughts, feelings, body, and social relationships their entire being in effect. In spite of its enormous importance, depression often goes undetected or is not suitably treated. This results in great suffering and a lower quality of life for those affected and their family members. It has become increasingly clear over recent years that depression is a chronic stressinduced disorder. Hence, it is also referred to as “stress depression”. It is a risk factor in the development of other widespread serious Best regards, illnesses, including heart attacks, strokes, osteoporosis and diabetes. Left untreated, depression can reduce life expectancy. PD Dr. med. Dr. rer. nat. Martin E. Keck Depression is a serious illness, but it can be cured.

Sustained overactivation as quickly as possible. of the stress hormone system is usually the cause of this. Left untreated, this overactivation can also lead to possible secondary diseases such as high blood pressure, heart attack, stroke, diabetes and osteoporosis. Therefore, careful sustained treatment is very important.What do we mean by depression episode. As the number of episodes increases, so does the risk of yet another episode. Therefore, careful treatment of each individual disorder is all the more important. Symptoms of depression Depression can have many symptoms and some will be more pronounced than others. Typically, there is a noticeable variation in complaints from person to person. According to the criteria of the World Health Organisation (ICD10), a depressive episode is characterised by a persistent low mood for at least two weeks. This is accompanied by a lack of ability to feel joy and a loss of drive and interest as well as reduced concentration and general capacity. There are also characteristic physical symptoms, such as Depression: a common and important illness sleep disorders, loss of appetite and weight and the restriction of thoughts to the perceived hopelessness of the situation. These can even lead to As depressive disorders are so common, it is very important that doctors thoughts of death and actual suicidal intentions. Thinking is slowed and of all specialties and the public in general know how they can be treated mostly revolves around a single topic, usually how bad things are, how and alleviated. Some 15 of the population is affected, with women futile the situation is and how hopeless the future looks. twice as likely to suffer from depression as men (men: 10, women: 20). This means that all of us are bound to have a relative, associate or friend with this illness. Unfortunately, the disorder is still too commonly hushed up or goes undetected. As “depression” is often used in everyday Sleep disorders conversation to indicate just feeling a bit down, this is one reason why Sleep disorders can make it difficult for sufferers to fall asleep, cause disturbed sleep with repeated waking and depression is underestimated. early waking. The sufferer feels as if he is not getting enough sleep and that what sleep he is getting is neither restorative nor deep. Even a long sleep can bring little tangible recuperation if there is no deep sleep or sleep The disorder can affect anyone of any age – from children to the elderly. where we dream or if the individual sleep stages are not run through in sequence.This is what happens with It can become chronic in approximately 1520 of cases, particularly if depression.

Physical symptoms, vegetative disorders and A relatively small trigger (such as a change of job) may often be enough to trigger the illness after many years organ problems are prominent with this. Another subtype – “melancholic of the stress building up. Many times there is also vague physical pain, such as increased sweating, dizziness, depression” – is characterised by pronounced morning lows, weight loss, headaches, problems in the gastrointestinal tract and muscle pain. Sleep disorders are very common with this joylessness and loss of libido and interest. Depression can manifest itself type of depression also.

Men are more prone to these kinds common as a whole in later life. However, depression is often overlooked in the elderly and may go untreated for of symptoms. years. Older patients are more likely to keep quiet about depressive symptoms and complain instead about other physical disorders. Therefore, different physical symptoms are more often to the fore in the elderly than younger patients. Vague pains in the elderly may often indicate an underlying depression, for example. Latelife depression may also arise or be fostered by a lack of nutrition or incorrect diet or through insufficient fluid intake. Headaches Back pain Dizziness Neck pain Postpartum depression Drowsiness particularly with women Postpartum depressive episodes affect around 1015 of women and usually start in the r fi st or second week.

In the case of people susceptible to this, it can cause a metabolic disorder in the brain and thus depression. Possible physical symptoms of depression. The physical complaints may be so pronounced that detection of the underlying mental complaints becomes difficult. We refer to this as masked depression.Risk of suicide It’s important to know how great the risk of suicide is for each person with depression. This is best identified by directly discussing it with the person affected, and finding out how intensively and how often he finds himself thinking about suicide. It is often supposed that this should never be discussed with a depressed person as it may just “give them ideas”. This isn’t the case. In their despair, every depressed person has already at least thought of this possibility and usually finds it a relief to finally talk about it. Suicidal tendencies represent an emergency People at risk of suicide must be seen by a doctor as quickly as possible. Depression: a life‑threatening illness Depression is a serious illness that can even be lifethreatening in some cases. It can end in death if left untreated. Death from depressionrelated suicide is the second most common cause of death amongst people of up to 40 years of age after accidental death. Almost all patients with severe depression have at least suicidal thoughts. If depression is recognised and treated, the often overwhelming wish to die also disappears. “ The man, who, in a fit of melancholy, kills himself today, would have wished to live had he waited a week ” Voltaire, author and philosopher, 1694–1778What causes depression Depression affects the entire body What triggers “stress depression” Depression is a risk factor for vascular complaints such as heart disease There is rarely just one cause of depression. Usually there are a number of interlinked factors and an innate and stroke. Therefore, it is probably as important as the classic risk factors susceptibility to the illness. Acute stresses such as the loss or death of an important person to whom we are close of smoking, being overweight and lack of exercise, although the general or chronic pressure situations can trigger a depressive disorder. There are often social factors requiring us to public is far more aware of these and they feature much more prominently adapt to new circumstances (such as a marriage, unemployment, retirement) before a depression. However, not in preventive health policy strategies. Depressive disorders can also lead all patients have these kinds of triggers. Many depressions can affect people out of the blue. Therefore, one to osteoporosis and adult onset diabetes. Therefore, depression is now should be very careful about viewing depression simply as a traceable, understandable response to difficult life considered a “systemic” illness as it not only affects the brain but also circumstances. Serious strokes of fate do cause sorrow, a depressed mood and general feelings of being unwell, many other organ systems. All of this emphasises the huge importance of but these may not necessarily be depression. However, if a depressive disorder exists it must be treated rigorously. early, careful and sustained treatment. A person may often have been under stress for many years without being ill. However, a relatively small event in itself may be the straw which breaks the camel’s back and triggers the illness. The brain’s metabolism is disturbed during depression, with the neurotransmitters serotonin, noradrenalin and dopamine out of kilter with one another. The disturbed control system for stress hormones is the cause as persistent overactivation of the stress hormone system can disturb nerve cell metabolism to such a degree that the production Joylessness Energy and degradation of the transmitters is derailed. They are either present in too low of a concentration or transmission Changes Vegetative Irritability Drive Feeling empty inside in mood disorders Appetite is no longer working correctly. If transmission between the nerve cells is disturbed as a result, this also gradually Feelings of guilt Sleep Hopelessness Libido Stroke lowers how we feel and our thoughts resulting in a lack of drive, loss of appetite, sleep disorders, difficulty Suicidal tendencies Heart rate Heart attack concentrating and other symptoms of depression.

Treatment concept A holistic concept is required to effectively treat depressed patients. This may include various psychotherapeutic approaches, such as cognitive behavioural therapy, depth psychological therapies and conversational therapy, The three stages of effective treatment of depression selected or individually combined according to the needs of the respective patient. Besides drug therapy, individual and group therapies may also be applied along with additional bodyoriented or creative therapeutic procedures, Acute treatment: relaxation therapies and stress management sessions (such as biofeedback, progressive muscle relaxation as per Improves and eases complaints.

Our feelings, thoughts and actions constantly affect each other and our physical functions. Feeling low can be accentuated further by negative thoughts, for example. Social withdrawal, which is often the natural consequence of feeling bad, further strengthens the unpleasant thoughts and feelings. This generates more stress which simply perpetuates the vicious circle in which the depressed person finds himself trapped. Psychotherapeutic treatment offers starting points for breaking depression‘s vicious cycle. It is often important to take up activities again which can improve one’s mood with therapeutic support. When depressed, a person just isn’t capable of doing this alone. It’s also important to recognise how certain situations can almost automatically trigger certain negative feelings and thoughts when a person is depressed. Typically depressed thoughts are onesided and negatively contorted. Depression causes us to see everything through a dark lens. Psychotherapy helps us to slowly rid ourselves of this lens.Interpersonal psychotherapy (IPT) Interpersonal psychotherapy is specifically tailored to the treatment of depression. It assumes that interpersonal relationships can significantly contribute to the development of depression. It is thought that a patient’s earlier interpersonal and mental experiences also manifest themselves in current behaviour. For example, stressful events (such as the death of a loved one or separation from a partner) and difficult life circumstances (such as bullying in the workplace, losing a job and retirement or permanent disputes with family members) can cause depressive symptoms to appear. For other patients, working through moments of loss (mourning) or managing transitions between particular social roles (such as when children leave home or a person enters retirement) can be important. The goal of interpersonal psychotherapy is to reduce depressive symptoms and improve interpersonal relationships in the private and/or professional spheres. Further elements of psychotherapy “Stress management” is another important component of psychotherapy. Psychoanalytic or depthpsychological Cognitive behavioural therapy therapy can also be very useful in individual cases. These attribute great significance to childhood development. All of us develop behavioural patterns, mindsets and emotional responses Psychoanalysis assumes that influences in our early years in particular can leave tracks in our psyche. In therapy, typical to us over our lifetime through personal experience and imitation. the patient works on recognising and processing hidden or suppressed conflicts. In respect of the development of depression, there are a range of typical thought and behavioural patterns which can lead to illness when In the case of „systemic (family) therapy”, the focus is on the group (= system) in which the individual lives. combined with high pressure situations and chronic stress. Problematic This system might be a married couple, a family, a group of friends or a team at work. It is assumed that the ill behaviours, thought patterns and mindsets are specifically tackled and person is simple a “bearer of symptoms” and the causes of his problems must be looked for and worked through examined during treatment. “Cognitive behavioural therapy” focuses on in the system as a whole. As with interpersonal psychotherapy, interpersonal and social aspects are also at the both negative thought patterns and on the behavioural level. Changing a centre of this. person’s behaviour, such as by getting them to take up pleasant occupations and social activities again, slowly leads to positive emotions and new experiences. This in turn fosters a changed mindset and vice versa. Amongst other things, the aim of cognitive behavioural therapy is to impart skills for successfully and satisfactorily constructing social relationships and dealing with one’s feelings. Another goal may be encouraging the patient to work through stressful experiences from the past, current crises and difficult life situations.Drug therapy While excellent treatment results can usually be achieved through Antidepressants do not increase the risk of suicide. psychotherapy alone in the case of minor forms of the illness, However, pharmacotherapy may worsen suicidal thoughts or actions in antidepressants are also used to treat moderate to severe depression. The the early phase of the treatment in some cases, as it may cause drugs are all based on the action principle of strengthening the nervousness and activation through the stimulation of the neural neurotransmitters (serotonin, noradrenalin, and dopamine) discovered in metabolism at this point in time, before the antidepressant effect is felt.

It was long thought that This underpins the existing need with depression to treat and support antidepressants only affect the level of concentration of these patients closely and to carefully check the need for temporary prescription neurotransmitters.

In severe cases, the new methods of “vagus nerve stimulation” (VNS) and “transcranial magnetic stimulation” (TMS) are being successfully applied in specialised centres by experts. Treatment can also be supplemented with suitable complementary medicine approaches, including naturopathic concepts such as phytotherapy (herbal medicine) and hydrotherapy (water applications, such as Kneipp therapy), traditional Chinese medicine (such as acupuncture, qigong), massages and aromatherapy. Wake therapy Sleep deprivation lifts our mood. This may sound strange at first, as many depressive patients are already suffering from sleep disorders. However, sleep deprivation, usually partial only, has proven excellent results in the treatment of depression. The patient goes to bed normally and is woken at around one in the morning. Relaxation techniques It’s important that the patient does not even take a nap during the wake therapy or the day after. This can destroy the overall moodenhancing effect. This therapy is usually conducted in a therapeutic support group as it’s very difficult to accomplish this alone.
