Kenan undergoing an ABR (Auditory Brainstem Response) which records brainwave activity in response to sound.
The NCV (Nerve Conduction Velocity) where an electrical impulse is measured as it is transmitted through the nerve. A delay in the speed of transmission indicates nerve disease. In relation to Krabbe, Kenan did much better on this test last year than expected.
Waiting for Kenan to come out of sedation, post MRI. The images will show the demyelination as it has progressed through his brain. The results of all tests will be compared with those from last year tracking the course of the disease up to this point.
