[Neuroimaging investigation in psychiatry]

Area of Science:

• Neuroscience
• Psychiatry

Context:

• Schizophrenia is a prevalent mental disorder affecting 1% of the global population.
• Onset typically occurs during early adulthood (18-25 years), impacting individuals during their most productive life stages.
• Characterized by positive symptoms (hallucinations, delusions) and negative symptoms (social deficits, poor self-care).

Purpose:

• To review and synthesize findings from magnetic resonance imaging (MRI) studies in patients diagnosed with schizophrenia.
• To highlight the neuroanatomical changes associated with schizophrenia as revealed by MRI.

Summary:

• Recent MRI studies indicate schizophrenia is characterized by a loss of brain gray matter (neuropil).
• This gray matter reduction is evident in specific neocortical regions.
• The loss occurs both before the full onset of symptoms and progresses in the initial years post-onset, correlating with symptom worsening.

Impact:

• MRI findings provide crucial insights into the neurobiological underpinnings of schizophrenia.
• Understanding these structural brain changes is vital for developing targeted therapeutic strategies.
• Further neuroscience research and interdisciplinary collaboration are essential for elucidating the pathophysiology of schizophrenia.
