Obviously the authorities have information to suggest this event was possibly related to mental health issues.
Not long before the Germanwings accident, I raised the mental health topic within pilots to a few work colleagues (I won't state who I was working for at the time). The response was, ahh the company's SMS will pick the issue up in conjunction with HF/NTS. I also raised the question again, this time in writing to a broader group of work colleagues after the Germanwings accident, what response did I get? nil, zilch.
This issue is a real threat to aviation, as the negative effects of this terrible illness can potentially have very widespread effects on a large amount of people.
Regardless off what the root cause of this accident was, mental health within aviation must be addressed a lot better than it currently is.
