Inflammation in psychiatric disorders: what comes first?

Area of Science:

• Neuroscience
• Psychiatry
• Immunology

Background:

• Neuropsychiatric disorders and inflammation share a complex bidirectional relationship.
• Patients with these disorders often display systemic inflammatory responses.

Purpose of the Study:

• To explore the intricate connection between inflammation and neuropsychiatric disorders.
• To identify potential triggers and mechanisms driving this inflammation.

Main Methods:

• Review of existing literature on inflammation and neuropsychiatric conditions.
• Analysis of the role of proinflammatory cytokines in brain function.
• Investigation of inflammation triggers such as neuroendocrine, metabolic, and lifestyle factors.

Main Results:

• Proinflammatory cytokines impact mood, cognition, and brain plasticity.
• Chronic inflammation is linked to neuroendocrine dysregulation, metabolic changes, and gut microbiota alterations.
• Early-life stress is associated with inflammation preceding neuropsychiatric disorder onset.

Conclusions:

• Inflammation is a significant factor in the pathophysiology and progression of neuropsychiatric disorders.
• Understanding inflammation's triggers is crucial for developing novel therapeutic strategies.
• Interventions targeting inflammation may offer new avenues for treating mood disorders and schizophrenia.
