This is the second time that Nan, who also writes under the name Nan Spowart, has featured in the group's journalism awards - she took the title in 2002 for a piece she wrote for the Daily Record.
This time around her article 'Epilepsy no barrier at work' in The Herald was selected as runner-up from 26 entries by the judging panel which included Scottish NUJ Secretary Paul Holleran, broadcaster Cathy MacDonald, BBC Scotland's head of news and current affairs, Atholl Duncan and patron Baroness Veronica Linklater.
Cathy MacDonald said of Nan's article: "This was clear concise writing, with the focus of two individuals who have two separate forms of the condition.
"Both are high profile and both highlight the reality of living with epilepsy.
"The article attempted to deal with issues of stigmatisation on a wider level.
Veronica Linklater commented: "This was a professionally told story."
