Also, the older you are the more protective (against depression) it is to have children.

Patients need to know that depression fluctuates over time and can be treated effectively with medicine and/or psychotherapy. If they can be persuaded to give it time, they may find that they choose differently when making the decision clear of depression symptoms. That's all we want: for doctors and patients to make the best decisions on a case-by-case basis.

Our findings do not support these beliefs. In the present study, we found no relationship between brain shrinkage and education level.

We found that, on average, men aged 64 years have smaller brains than men aged 60. However, despite this shrinkage, cognitive functions -- like memory, attention and speed of processing -- are unaffected.

It is known that the brain shrinks over the course of a person's life, although the exact trajectory is not well understood, and there are huge individual differences.

When children start putting together in their minds that Santa Claus may not be real, they'll ask questions -- and that's an opening for parents to get them talking about what's logical or not to them.
