Searching for Nephew... Male/PA/ born mid 1990s

I am actually here hoping to find my nephew. He belonged to my brother and was given up as a baby in An open adoption in the middle to late 1990s. I started looking for him when I became an adult. I ran into his biological mother whom told me he might have the same condition as me. I know he doesn’t know me, but I still worry about him. I know my brother’s full name, his mother’s first name, and what she told me was my nephew’s first name.
