At what life stage can mental illness be diagnosed?

Mental illness can be diagnosed at any life stage, which reflects the complex nature of mental health issues that can affect individuals from infancy through older adulthood. Various mental health conditions may present themselves at different ages, and recognizing this allows for timely intervention and support regardless of when symptoms emerge.

For instance, conditions like anxiety or depression can appear early in childhood, while other disorders, such as schizophrenia, might typically present in late adolescence or early adulthood. Furthermore, situational factors and life transitions, which are common throughout all stages of life, can impact mental well-being at any age. Therefore, mental health professionals consider the entire lifespan when diagnosing and treating mental health issues, emphasizing the importance of awareness and understanding across all ages.
