Did my other suggestion not work?

It's true that the documentation of amsthm isn't very clear.  Here's  
an example of making your own theorem style:

\documentclass{article}
\usepackage{amsthm}

\newtheoremstyle{mytheorem}%
{3pt}% ⟨Space above⟩
{3pt}% ⟨Space below⟩
{\itshape}% ⟨Body font⟩
{\parindent}% ⟨Indent amount⟩
{\bfseries}% ⟨Theorem head font⟩
{.}% ⟨Punctuation after theorem head⟩
{.5em}% ⟨Space after theorem head⟩
{Theorem \thetheorem\quad\normalfont(\thmnote{#3})}% ⟨Theorem head  
spec (can be left empty, meaning ‘normal’)⟩
\theoremstyle{mytheorem}
\newtheorem{theorem}{Theorem}

\begin{document}

\section{A section}

\begin{theorem}[Some text]
\[ \pi
\]
\end{theorem}

\end{document}
