Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Neuroscience

Background:

• Borderline schizophrenia is considered a distinct diagnostic entity.
• This condition is characterized by perceptual-cognitive abnormalities.
• It exhibits familial distribution and genetic links to schizophrenia.

Purpose of the Study:

• To advocate for the inclusion of borderline schizophrenia in the DSM-III.
• To characterize the core features of borderline schizophrenia.
• To discuss the relationship between borderline schizophrenia and schizotypal personality.

Main Methods:

• Clinical observation and diagnostic criteria analysis.
• Review of familial and genetic studies.
• Comparative analysis with schizotypal personality disorder.

Main Results:

• Borderline schizophrenia is a chronic illness with distinct perceptual-cognitive abnormalities.
• A familial distribution and genetic relationship with schizophrenia are evident.
• The term borderline schizophrenia is preferred over schizotypal personality.

Conclusions:

• Borderline schizophrenia is a valid diagnostic entity.
• Its inclusion in the DSM-III is recommended.
• The term better reflects the underlying genetic vulnerability and episodic nature of symptoms.
