Sacked Commonwealth Games Organising Committee chief Suresh Kalmadi was discharged on Thursday evening from the All India Institute of Medical Sciences, where he underwent several tests for memory-related disorder dementia.
Lodged in Tihar jail for nearly three months in connection with the multi-crore Commonwealth Games scam, 67-year-old Kalmadi was admitted to AIIMS for a medical check-up on August 1.
"He was discharged at 5.45 pm from the hospital and reached in New Delhi inside the prison premises at 7 pm," Deputy Inspector General of Prisons R N Sharma said.
"He has undergone cardiac, neuro and endrocrinology testing in the past three days of his stay in the hospital. The test reports have been sent to the jail authorities," said Dr Y K Gupta, spokesperson and head of the department of pharmacology, AIIMS.
Sources said doctors have carried out positron emission tomography scan of his brain to assess a wide range of conditions including the determination of dementia or any brain lesion.
He has undergone a number of blood chemistry tests so that a clear picture of his ailments could emerge, sources said.
A three-member team of doctors including neurologist Dr M V Padma, cardiologist Dr Rakesh Yadav and Dr Aarti Vij was formed to conduct the investigations.
