Mental health is defined as a state of well-being in which a person realizes their abilities, copes with the stresses of everyday life, works productively, and is able to contribute to society. Short-term fluctuations and difficulties are normal and are common to all of us. In general, a person is able to cope with these problems independently. When adopting a brain-healthy lifestyle, it is important to clearly distinguish between different risk factors for brain health and to focus on modifiable risk factors in practical work. However, when mental health problems persist over a longer period and/or difficulties in coping significantly interfere with daily functioning, professional help is often necessary.
