[Affective disorders, diabetes and carbohydrate metabolism]

Area of Science:

• Medical and Biological Sciences
• Psychiatry
• Endocrinology

Background:

• Diabetes mellitus is a complex metabolic disorder with significant implications for mental health.
• Affective disorders, such as depression and anxiety, are frequently comorbid with diabetes.
• Understanding the bidirectional relationship is crucial for comprehensive patient care.

Observation:

• The study reviews clinical, therapeutic, metabolic, neuro-endocrine, and epidemiological evidence linking diabetes and affective disorders.
• An original clinical case is presented to illustrate the observed connections.
• Existing literature data are critically analyzed.

Findings:

• Metabolic dysregulation in diabetes can influence neurotransmitter systems and mood regulation.
• Neuro-endocrine pathways, including the hypothalamic-pituitary-adrenal (HPA) axis, are implicated in both conditions.
• Shared genetic or environmental factors may contribute to the comorbidity.

Implications:

• Highlights the need for integrated treatment approaches addressing both physical and mental health in diabetes patients.
• Suggests potential therapeutic targets for managing affective disorders in individuals with diabetes.
• Identifies key areas for future research, including longitudinal studies and biomarker discovery.
