Late infantile Krabbe leukodystrophy: MRI and evoked potentials in a Japanese girl

T KurokawaT Kitaguchi


A Japanese girl showed deterioration in development from the age of 13 months. At the age of 16 months, there were mild spastic diplegia, increase in cerebrospinal fluid protein to 61.5 mg/dl and deficient galactosylceramidase I. Magnetic resonance imaging (MRI) demonstrated a high signal intensity with increased T2 in the centrum semiovale. Short latency somatosensory evoked potentials (SSEPs) showed a prolonged N13-N20 interpeak latency followed by abolition of N20. Brainstem auditory evoked potentials (BAEPs) were normally followed by prolonged interpeak latencies of wave I-V. This may be the first report of what we consider to be the late infantile form of Krabbe disease with MRI and evoked potential examinations.

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
