[Basic symptoms in schizophrenia, their clinical study and relevance in research]

Area of Science:

• Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• Basic symptoms are subtle, subjective disturbances in schizophrenia, impacting drive, affect, cognition, perception, and stress tolerance.
• First described by Huber, these symptoms are early indicators of schizophrenia and can evolve over time.
• Their assessment, alongside ultra-high risk criteria, is crucial for defining clinical risk states for psychosis.

Purpose of the Study:

• To provide an updated review of the concept of basic symptoms in schizophrenia.
• To highlight the potential of basic symptoms in identifying neurobiological correlates for etiological research.

Main Methods:

• Phenomenological approach.
• Review of existing literature on basic symptoms and their role in psychosis risk assessment.
• Exploration of the link between basic symptoms and neurobiological research.

Main Results:

• Basic symptoms represent early, subjective experiences in schizophrenia.
• Assessment of basic symptoms is a key strategy for identifying individuals at clinical risk for psychosis.
• Basic symptoms offer a promising avenue for investigating the neurobiological underpinnings of schizophrenia.

Conclusions:

• Basic symptoms are valuable early indicators in schizophrenia, aiding in psychosis risk prediction.
• Further research into basic symptoms can illuminate the neurobiological basis of schizophrenia.
• Integrating basic symptom assessment into clinical practice may improve early intervention strategies.
