Yes, it is possible for someone to have schizophrenia and not know it until later in life. Schizophrenia is a complex and chronic mental disorder that typically emerges in late adolescence or early adulthood, but it can sometimes have a later onset. The age of onset for schizophrenia can range from late teens to mid-30s or even later, though it is less common in older adults.
The symptoms of schizophrenia can be subtle and develop gradually, which may lead to delayed recognition of the disorder. In some cases, individuals with schizophrenia may not fully understand or recognize their symptoms, or they may attribute them to other causes, such as stress, depression, or anxiety. Moreover, the stigma and misconceptions surrounding mental health issues can also prevent people from seeking help or acknowledging their symptoms.
It's important to note that schizophrenia is a treatable condition, and early intervention and proper treatment can significantly improve an individual's quality of life. If someone is experiencing symptoms that may be suggestive of schizophrenia or any other mental health concern, it is crucial to seek professional help from a qualified mental health specialist for assessment and appropriate care.
