Doctors will carry out "brain stem function" test on Awami League Leader Mohammed Nasim to take final decision on whether they will remove his life support system.

"After several tests of brain stem function, we will be able to know whether he is brain dead. Then, we will decide on his life support system," Dr Raziul Haque, a neurosurgeon at the Bangladesh Specialized Hospital where the AL MP is being treated, told The Daily Star.

"But before removing the life support system, we will have to take consent from Mohammed Nasim's family members," Dr Raziul said.

Infected with Covid-19 and later suffering a stroke, the former health minister and Awami League Presidium Member Nasim is in deep coma with life support since June 6.

A thirteen-member medical board led by Kanak Kanti Barua, a renowned neurosurgeon and Vice Chancellor of Bangabandhu Sheikh Mujib Medical University, on Sunday said Mohammad Nasim's condition is very critical and he remains unconscious.

Dr Kanak Kanti Barua further said Mohammed Nasim's blood pressure is also unstable.

Nasim's son Tanvir Shakil Joy, also a former Awami League MP, told the media on May 5 that his father had undergone a successful surgery after suffering a stroke on June 5.

On June 1, Nasim was admitted to Bangladesh Specialized Hospital as he was feeling unwell. Later, he tested positive for coronavirus.
