Common and severe mental illness

Mental health is a high public health priority area.

Common mental health disorders are conditions that cause marked emotional distress and interfere with daily function, but do not usually affect a person's cognition, insight and perception of reality. They comprise different types of depression and anxiety, and include obsessive compulsive disorders. Severe mental illness includes schizophrenia, bipolar affective disorder and other psychoses.

The Covid-19 pandemic has been a difficult and stressful time for many people. While the majority of people remained mentally well, studies have reported increases in levels of anxiety, depression, loneliness, sleep issues and stress.  Evidence has shown it exacerbated existing mental health issues. 

Later presentations to GPs, cancellation of appointments and longer waits to see specialists or access specialist services will have had an impact. Some people may also be reluctant to address concerns or attend GP practices due to fear of catching Covid-19. These missed diagnoses mean that treatment may be delayed or doesn't happen, which may lead to worsening mental health. The legacy of the pandemic and the current cost-of-living crisis will mean that monitoring mental health is of vital importance.
