Depression in old age
In old age, there are certain peculiarities in terms of symptoms. Old-age depression is characterized by the same symptoms as depression in younger people. However, comorbidities (concomitant diseases) such as diabetes mellitus, apoplexy (stroke), Parkinson’s disease, or psychiatric disorders such as anxiety disorders or dementia complicate the diagnosis of depression in old age. In general, it can be said that in old age, especially in the presence of a need for care, existing physical complaints increase the risk of depression. In contrast to young people, however, older people often do not dare to admit their worsened mood or even to evaluate it as a symptom of illness. Older people, however, are more willing to talk about their anxiety. In addition, older depressives complain more about physical complaints. The following physical complaints are most frequently mentioned:
- Rapid fatigue
- Lack of strength
- Shortness of breath
- Palpitations
- Dizziness
- Headache
- Pain
