Dogs and Schizophrenia
- Ever since we domesticated dogs, it has provided us with companionship and emotional well-being. A study suggests that being around dogs from an early age may lessen the chances of developing schizophrenia.
- The relationship between exposure to a pet cat or dog during the first 12 years of life and a later diagnosis of schizophrenia or bipolar disorder was investigated.
- Earlier studies have said that exposure to these pets may alter the immune system by changing a home’s microbiome and pet-induced stress reduction effects on human brain chemistry.
- Eg: “immune modulation” may reduce the risk of developing psychiatric disorders.
- Explanations for this possible ‘protective’ effect from contact with dogs say that something in the canine microbiome gets passed to humans and bolsters the immune system against or subdues a genetic predisposition to schizophrenia.
- A better understanding of mechanisms would aid in developing appropriate prevention and treatment strategies.
