Understanding the transition from depression to schizophrenia is a complex topic that requires a nuanced approach. Let's break down your questions one by one.

1. Transition from Depression to Schizophrenia: It is true that negative symptoms of schizophrenia can sometimes be misdiagnosed as depression, especially in the early stages. However, if a patient has been diagnosed with major depressive disorder for over five years without any signs of schizophrenia, the likelihood of developing schizophrenia later is relatively low. Research indicates that while individuals with a history of depression may have a slightly increased risk of developing schizophrenia, this risk is not significant if there are no psychotic symptoms (like hallucinations or delusions) present during the depressive episodes. The exact probability can vary based on individual factors, including family history and other risk factors.

2. Symptoms Described: The symptoms you describe, such as repeating phrases and creating new ones, along with an excessive focus on appearance, may not necessarily indicate schizophrenia, especially in the absence of hallucinations or delusions. These behaviors could be indicative of anxiety or obsessive-compulsive tendencies rather than schizophrenia. Schizophrenia typically involves more severe symptoms, including significant disorganization in thought processes, hallucinations, and delusions. The concern about appearance might suggest body dysmorphic disorder rather than schizophrenia.

3. Side Effects of Medications: Regarding the side effects of specific medications like "帝拔顛" (likely referring to a medication such as Olanzapine) and "憂必晴" (possibly referring to Mirtazapine), both can have various side effects. Common side effects of Olanzapine include weight gain, sedation, and metabolic changes, while Mirtazapine can cause sedation, increased appetite, and weight gain as well. It's crucial to discuss any side effects with a healthcare provider, as they can help manage these issues effectively.

4. Impact of Untreated Depression: Untreated depression can indeed worsen over time and lead to more severe mood disorders, including bipolar disorder or even psychotic disorders in some cases. However, not every individual with untreated depression will develop these conditions. The progression depends on various factors, including genetic predisposition, environmental stressors, and individual resilience.

5. Age and Risk of Schizophrenia: Schizophrenia typically manifests in late adolescence to early adulthood, with most cases appearing before the age of 30. If an individual has not shown any signs of schizophrenia by the age of 30, the risk of developing the disorder decreases significantly. While it is not zero, the likelihood of onset after this age is considerably lower.

In conclusion, while there are connections between depression and schizophrenia, they are distinct disorders with different treatment approaches. If you or someone you know is experiencing concerning symptoms, it is essential to seek professional help. Mental health professionals can provide accurate diagnoses and appropriate treatment plans tailored to individual needs. Early intervention is key in managing mental health conditions effectively.
