Hello there!

Hope you are doing fine.

Dr. title is given to any candidate who have completed Ph.D in any of the discipline.

But if you are asking for Doctor who treats people from various diseases, you need to do any of the courses like MBBS, BAMS, BHMS, BDS, Psychology, physiotherapy, etc.

Out of these courses, admission in physiotherapy and Psychology can be taken without clearing NEET.

Hope it helps.

Stay safe.

Good luck.
