Hi Alphabet
There is some evidence that industrialization might increase mental illness. Some suggest that industrialization contributes to the breakdown of the family unit (so social support decreases). Others argue however that it’s not prevalence increasing, but knowledge that has increased. So people are more likely to be diagnosed because they are aware of the mental illness and there are more psychologists/psychiatrists to diagnose these individuals. There is evidence for both.

Hello Laura,
If someone is suffering from anxiety/depression, you can’t force that person. I would recommend that 1. You encourage the person to seek help from a mental health professional (counsellor, psychologist, psychiatrist). 2. Keep inviting but not forcing. There is research that shows doing activities that are usually pleasurable is helpful for a depressed person. If a person is anxious, being forced to do something may increase the anxiety. Either way, the person needs to be willing to do it.
Distraction is a short-term solution, so for a long term solution the cause of the anxiety/depression needs to be dealt with head on.

Dementia is more than just cases of forgetfulness. There are rare cases of early dementia (40 – 50 years old) but most cases happen after 65. If you are concerned about someone, take note if there are other symptoms e.g. language difficulties,confusion with time and place.
