ADHD diagnosis for Adults in Pune. Case?

Where can I get diagnosis for ADHD in Adults In Pune? And what is the general cost of such test? I've been recently diagnosed with depression and it's been recurrent since 2019. I have a lot of trouble focusing and have no motivation to do tasks even though they are very important and I know they need to be done. I have been taking Nexito since past 8 months, and it has stabilized my mood to a limit however when it comes to motivating myself to do tasks however important or important I find myself unable to do it. The dosage for Nexito has been increased twice in four months from 10 mg to 15 mg and now 20 mg. I was prescribed modalert during exam periods but after first few days my body got accustomed to it and the symptoms were back in full force. What can be done in such a case?
