Khandakar Abdul Malek Shahidullah, a Language Movement veteran from Mymensingh, is undergoing treatment at Bangabandhu Sheikh Mujib Medical University (BSMMU).
The 85-year-old was admitted there for better treatment on Tuesday, family sources said.
Malek's right arm and leg became paralysed after he had a stroke in October last year. He has been bedridden since he had another stroke two months later, said his youngest son Khandakar Manzur Malek Sudipta.
Afterwards, the language hero was admitted to Mymensingh Medical College Hospital from where he was released 10 days later, said Sudipta.
At BSMMU, several tests have been conducted. After getting reports, a medical board will decide to start his treatment, Sudipta quoted doctors as saying.
"Following an initiative by former law minister Abdul Matin Khoshru, also presidium member of Awami League, we took him to the hospital," said Sudipta.
Suraiya Malek, wife of the Language Movement veteran, said, "The government should take the responsibility of my husband's treatment. In this regard, we appealed to them on various occasions."
Malek was only 17-year-old in 1952 when the Language Movement demanding Bangla as a state language broke out.
Malek, a ninth-grader at that time, and eight of his fellows were expelled from Cooperative High School in Jamalpur for taking part in a procession in Dewanganj.
