Agogo suffered stroke in December 2014 two years after hanging his boots on his football career.
The debilitating illness caused the striker to develop difficulty in moving and controlling his right hand.
Agogo in 2017 told the BBC Four documentary titled Speechless that he had troubles with speech following the illness which he said left him lacking confidence and socially isolated.
The immediate cause of his death has not been established.
The forward began his career with the Owls, playing three games for the then Premier League side between 1997 and 2000.
He went on to score over 100 career goals, his most notable spell coming with Bristol Rovers, for whom Agogo scored 45 goals in 140 games between 2003 and 2006.
He also helped Nottingham Forest to promotion from League One in 2007/2008, finishing as the club’s top goalscorer as they finished runners-up in the division.
The name Agogo became a household name in Ghana during his 27-game stint with the Black Stars of Ghana scoring 12 goals.
