A new study has concluded that living alone is linked to common mental disorders. The authors have also identified the main driver of this worrying relationship, Medical News Today reports.

Some common mental disorders (CMDs) include mood disorders, anxiety, and substance use disorders.

According to some studies, almost one-third of people will experience a CMD in their lifetime.

These conditions can have a significant impact on the individual, of course, but due to their high prevalence, they also affect society at large.

Due to the widespread influence of CMDs, scientists are keen to understand the full range of risk factors that feed into mental health.

In recent years, scientists have investigated whether living alone might be one such risk factor.

A new study, the results of which now appear in the journal PLOS ONE, takes a fresh look at this question. The study authors conclude that there is a link between living alone and CMDs. They also find that it affects all age groups and sexes, and that primarily, loneliness is the driver.
