[Tex/LaTex] Title of the theorem


in my paper the text inside theorem is italic while the word Theorem 1 is bold and not italic. I would like to have a title of the theorem also not italic. The example is here:

Theorem 1. (The title) Let the set…

How can I do it? I tried to type
\begin{theorem}{title here}
but it doesn't work.

\begin{theorem}[The title]
Some statement

should do what you want. The standard LaTeX setting prints in boldface also the title, which doesn't happen when amsthm is loaded.
