Having a close family member, such as an uncle, with schizophrenia does increase the risk of developing the condition compared to the general population. Schizophrenia has a complex and multifactorial etiology, involving a combination of genetic, environmental, and neurobiological factors.
The exact genetic risk varies depending on the specific relationship to the affected individual. While the risk is higher for first-degree relatives (parents, siblings, and children), the risk for nieces/nephews (such as your case with your uncle) is still higher than the general population but lower than that of first-degree relatives.
Keep in mind that having an increased risk does not mean a definite outcome. Many individuals with a family history of schizophrenia never develop the condition, and it's not entirely deterministic. On the other hand, some people without a family history of schizophrenia may develop the disorder.
If you are concerned about your risk or have noticed any symptoms that cause you distress, it's important to talk to a healthcare professional or mental health specialist. They can provide you with more personalized information about your risk factors and can offer guidance on managing your mental health.
Early intervention and awareness of risk factors can be valuable in promoting mental health and well-being. Additionally, leading a healthy lifestyle, managing stress, and seeking support when needed can positively influence mental health outcomes.
