At age of 52 years ca course advisable or not

yes ofcourse i have one aunty (aged 56years ) who has cleared her cpt in first attemp and now going through ipcc exam so yes it is advisable if you have pasion to do it you can go for it.

age is not limit

Age doesn't matter to appear and pass CA examination, it is the will, passion and determination which matters. Classic example is S D Bala sir, the SFM Author.

Age dose not matter, being professional course, there is no retirement age. Anybody can practice till the last breath.If you have passion & firm determination than go ahead.
