Relatives said authorities had prevented Akhmedov from receiving medical treatment in the capital, Ashgabat.
Akhmedov was appointed prime minister of Soviet Turkmenistan in December 1989. He retained his job until May 1992, thus becoming the first head of government of the newly independent Turkmenistan.
After some time at the head of the Railways Ministry, he was appointed Turkmenistan's ambassador to Turkey.
Observers believe his transfer to Ankara heralded his downfall and eventual exile.
