Former Delhi deputy chief minister Manish Sisodia's wife Seema Sisodia, who is suffering from an autoimmune disorder, was admitted to a hospital in Delhi on Tuesday, party sources told PTI.
She was hospitalised after her condition deteriorated, they said.
This is the third time in the past few weeks that Seema Sisodia, 49, who suffers from multiple sclerosis, has been hospitalised.
She was admitted to the neurology department of Indraprastha Apollo Hospital in late April.
It is generally agreed that the impact of the disease accelerates with time and other factors such as increased physical and emotional stress.
Manish Sisodia, who is currently in jail in connection with the Delhi excise policy case, had earlier sought bail from court citing his wife's ill health and his son being abroad.
After the AAP leader was arrested in February, Delhi Chief Minister Arvind Kejriwal and his Punjab counterpart Bhagwant Mann had met Seema Sisodia and assured her of all support.
