"Umar has got an appointment with the neurologist on Wednesday and is accompanied by Dr Sohail Saleem," a source in the board said.
"We are hopeful that once this check up is completed, a clear picture will emerge about Umar's medical condition as he has already undergone MRI scans and was examined by a Lahore based neurologist," the source added.
The incident also led the board pulling him out of the T20 and ODI series in Zimbabwe.
However, Umar on returning home had told reporters he was perfectly fine and was ready to join the team in Zimbabwe, adding to the confusion about his medical condition.
"The truth is that even the board medical panel got a bit confused when they saw the medical reports about Umar which were taken in the West Indies. The reports indicated he was facing a epilepsy condition in advanced stage but tests and consultations in Pakistan point otherwise," the source said.
