Dr.Jaseja has worked as a faculty member in a Medical school for more than 33 years. His main research interest has been in epilepsy and epileptogenesis; in 2013, he was ranked Second in Epilepsy Research in India.
He has published papers on various aspects of epilepsy, especially association of epilepsy with sleep. He had advocated consideration of diagnosis of epilepsy even after the first epileptic attack (in 2009) long before the ILAE definition of epilepsy in 2014 that permits clinical diagnosis of epilepsy even after one epileptic attack associated with a 60% risk of a recurrent attack. Until this definition, clinicians usually waited for occurrence of a second attack thus delaying the initiation of anti-epileptic medication, causing anxiety and stress in the patients due to uncertainty and unpredictability of a second attack.His current work has been on Deep brain stimulation (DBS) in intractable epilepsy (IE). He has postulated a new target for DBS, namely Pedunculopontine nucleus (PPN), claiming that its stimulation is superior in therapeutic efficacy and success over the conventional DBS of anterior thalamic nucleus (ATN) in patients with IE.In 2005, Dr Jaseja initiated a debate on the epileptogenic potential of Meditation. He has published new guidelines for treatment of patients with cerebral palsy (CP), based on EEG. He has claimed that CP, contrary to popular belief, can change its course and progression with time and therefore, observation of new guidelines, quality of life of patients with CP may be improved.
He has studied the effects of vagal nerve stimulation and has shown and claimed its efficacy in patients with CP, post which, CP has been included in the list of indications of VNS, the links to which are: (http://www.aetna.com/cpb/medical/data/100_199/0191.html,http://www.anthem.com/medicalpolicies/policies/mp_pw_a053286.htm).
He has worked on interpretation of an EEG and shown how its misinterpretation can be prevented; further, he has also ideated how the yield of EEG-findings can be enhanced in patients with epilepsy. He has shown that the hallmarks of epileptiform activity namely ‘spike’ and ‘sharp’ waves (which hitherto were considered having same significance) posses differential clinical significance especially in patients with epilepsy.Interestingly, he has shown that the Indian traditional application of Shoe-smell in Epilepsy has a sound scientific basis. In a small study, shoe smell was reported to posses beneficial effect (reduction in duration and severity) during an epileptic attack.
