Mental illness, suicide and creativity: 40-year prospective total population study

Area of Science:

• Psychiatry
• Genetics
• Sociology

Background:

• Previous research indicated an overrepresentation of individuals with schizophrenia or bipolar disorder and their relatives in creative occupations.
• A larger sample size is needed to explore associations between creativity and a wider range of psychiatric diagnoses.

Purpose of the Study:

• To investigate if creativity is associated with all psychiatric disorders or only those with psychotic features.
• To examine the relationship between authorship and psychopathology.
• To validate previous findings on creativity and psychiatric diagnoses in a larger population.

Main Methods:

• A nested case-control study utilizing Swedish total population registries.
• Comparison of creative occupations in patients and their relatives against matched population controls.
• Inclusion of diagnoses: schizophrenia, bipolar disorder, unipolar depression, anxiety disorders, substance abuse, autism, ADHD, anorexia nervosa, and suicide.

Main Results:

• Creative professions were not significantly associated with most investigated psychiatric disorders, except for bipolar disorder.
• Authorship demonstrated a specific association with increased likelihood of schizophrenia, bipolar disorder, unipolar depression, anxiety disorders, substance abuse, and suicide.
• Creative professions were associated with first-degree relatives of patients with schizophrenia, bipolar disorder, anorexia nervosa, and siblings of patients with autism.

Conclusions:

• The link between creativity and mental health appears specific, particularly for authorship, which is associated with a spectrum of psychiatric conditions.
• Findings suggest a complex interplay between genetic predispositions, environmental factors, and creative pursuits.
• Further research is warranted to elucidate the underlying mechanisms connecting creativity and psychopathology.
