The scientists got down to discover if infants with SIDS had any measurable variations in butyrylcholinesterase ranges based mostly on the enzyme’s function within the computerized bodily capabilities. 

Butyrylcholinesterase is likely one of the enzymes which play a task within the physique’s cholinergic system, a reputation for varied mind capabilities that regulate issues like consideration, sleeping, and waking.

In search of solutions on the tragedy she discovered no ample rationalization for SIDS and went again to school to grow to be an professional in baby sleep to assist discover attainable therapies.
