Paranoid Schizophrenia, classified under ICD-10 code F20.0, is a type of schizophrenia marked by intense delusions and hallucinations, particularly auditory ones, while cognitive abilities and emotional responses remain relatively preserved. Schizophrenia, in general, is a chronic mental disorder affecting how individuals think, feel, and perceive reality, often leading to psychosis.
This specific type, of paranoid schizophrenia, involves severe paranoia, such as believing someone is trying to harm them or having grandiose ideas about themselves. Although no longer recognized as a separate subtype in modern psychiatry, it remains an important classification under ICD-10 for medical purposes.

Former Subtype | Characteristics |
---|---|

Causes of Paranoid Schizophrenia
- Genetic Predisposition
- Family History: Having close relatives with schizophrenia increases your risk of developing the condition.
- Multiple Genes: Many genes, not just one, may contribute to causing schizophrenia.
- Brain Structure and Function
- Brain Differences: People with schizophrenia may have differences in brain structure or function, affecting how the brain communicates.
- Neurotransmitter Imbalance
- Dopamine Imbalance: An imbalance in dopamine, a brain chemical, is thought to contribute to schizophrenia. Both too much and too little dopamine can impact thinking and behavior.
- Prenatal Complications
- Pregnancy Issues: Complications during pregnancy, such as low oxygen at birth, infections, or exposure to toxins, can increase the risk of schizophrenia later in life.
- Childhood Trauma
- Abuse or Neglect: Experiencing abuse, neglect, or trauma in childhood may increase the likelihood of developing schizophrenia as an adult.
- Stressful Life Events
- High Stress Levels: Significant stress or traumatic events (e.g., the death of a loved one) can trigger schizophrenia symptoms in people who are already vulnerable.
- Drug Use
- Cannabis Use: Using certain drugs, especially cannabis, has been linked to a higher risk of schizophrenia. It’s unclear if drug use directly causes the condition or worsens it in those at risk.
- Environmental Factors
- Poverty and Discrimination: Living in poverty or experiencing social discrimination may contribute to the development of schizophrenia, especially alongside other risk factors.
- Social Isolation
- Limited Social Support: Lack of social connections or support can increase the risk of schizophrenia, with isolation negatively impacting mental health.
- Psychosocial Stressors
- Difficult Life Circumstances: Challenges like unemployment or family conflict can trigger schizophrenia in those who are predisposed to the condition.
- Brain Injury
- Brain Damage: Some individuals with schizophrenia may have minor brain injuries or abnormalities that could contribute to the onset of the disorder.
