Almost definitely yes! Whilst it can develop in young children, this is quite rare. It seems to peak around adolescence and adulthood and often fluctuates, both between and within people – so some develop depression later or earlier than others and some develop depression a few times in their lifetime at various stages.
The biggest single factor for developing depression (and a lot of other conditions too!) is stress. So if we think about the lifespan, the first real encounter of significant stress is in young people with school pressure, puberty and finding their independence. When stress creeps up on us, particularly if we have a genetic predisposition to depression, or any mental illness really it can effect us at any age in developing symptoms.
We also need to think what we mean by depression – almost all of us will have symptoms of low mood, poor sleep and poor eating etc. Without receiving or even being at a level of clinical depression. And again, both types of depression can develop at any age.
