Mangaluru: Mental illness can leave families with difficult questions: Why did this happen? Could we have prevented it? Will another family member develop the same condition?
Psychiatric genetics is helping doctors answer some of these questions, but experts caution that genes alone cannot predict who will develop a mental health disorder.
Genes explain vulnerability, not destiny
Conditions such as schizophrenia and bipolar disorder have significant genetic components. However, they generally involve many genes interacting with environmental and developmental factors. A person may carry genetic vulnerabilities without ever developing an illness.
This is particularly important for Indian families, where mental illness may still be associated with stigma, superstition or feelings of guilt.
Genetic understanding can help families recognise that schizophrenia or bipolar disorder is not caused simply by poor parenting, a lack of discipline or a moral failing.
Genetic tests have important limits
Psychiatric genetics cannot currently provide a simple test that tells a healthy person they will definitely develop schizophrenia or bipolar disorder.
Instead, family history remains an important part of psychiatric assessment. Doctors may consider patterns of illness within a family while also looking at stress, substance use, developmental experiences and other environmental influences.
This approach can help families understand risk without creating unnecessary fear.
Early help remains crucial
For someone experiencing psychosis or other serious psychiatric symptoms, professional assessment and timely treatment remain more important than searching for a single genetic explanation.
Early intervention can improve recovery and help people continue education, employment and relationships.
For Indian families, the greatest value of psychiatric genetics may therefore be simple but powerful: replacing blame with understanding, and fear with informed support.
