Schizophrenia doesn't have a single cause. Instead, it develops from a complex combination of different factors. The three main contributing factors are:
• Genetics - Having a family member with schizophrenia can increase risk, though many people with schizophrenia don't have a family history
• Environment - Where and how you live can play a role
• Brain Chemistry - Differences in brain structure and chemical balances may contribute Some specific risk factors that may increase the likelihood of developing schizophrenia include:
• Being born in winter or early spring
• Living in urban areas
• Moving to a different country
• Experiencing long-term stress
• Complications before or during birth
• Using recreational drugs, especially during teenage years
• Having a parent or sibling with schizophrenia
It's important to understand that having these risk factors doesn't mean someone will definitely develop schizophrenia.
