One of the biggest fears of ageing and getting old is to lose one's mind. It is a well known fact that our mind does not perform as effectively and efficiently during old age as it used to do during our youth years. Old age is more often than not accompanied by certain signs of mental decline and dementia such as frequent forgetfulness, loss of focus, difficulty in learning and grasping new skills and things, and an overall decline in energy and drive.
However, the trouble arises when these above mentioned signs of mental decline or brain ageing become too rapid and frequent leading to premature mental decline. This premature mental decline rather than being a general sign of brain ageing signals something different and serious. Most of the times the rapid brain ageing and mental decline is a sign of some major mental illness or brain disorder like Alzhiemer's disease, senile dementia or Parkinson's disease.
