What will you say to convince the people who go to exorcists for treatment?

Will I would try to answer it in scientific way and non scientific way.

Explanation:

What happens when we die? there is surely a energy in our body that comes out, and as we know that energy cannot be destroyed or created so this energy goes back to a cycle from where it began.

Therefore we must say that the beginning is the end.

The beginning is the end.

Nothing is going to end, everything is moving on the same path in a cycle, the cycle of life and death. Now when we speak some words or mantras they gives an energy, they put a energy which is in a very complex form, i.e not the sound or vibration energy.

Here again we get the scientific way for it, the energy helps us the energy in our body to get out the system, there have been researches been conducted on this subject, and primary level results have been achieved successfully, you can check them out.

Now the religious rituals that happens before burial or cremation says the same thing there.

Science and Religion are interconnected, specially the Sanatan Dharma, because it's a way of life. You can search about this things. Going to a exorcist might sound funny rather than going to a Psychologist, but that's up to you if you know what is the power of your mind. That's a different thing, sometimes things are beyond the science and then it comes to religious beliefs, which are more mysterious than anything.
