T. Matsuishi et al., DECREASED CEREBROSPINAL-FLUID LEVELS OF BETA-ENDORPHIN IN JAPANESE PATIENTS WITH JOSEPH DISEASE, Annals of neurology, 36(3), 1994, pp. 441-443
We measured the cerebrospinal fluid (CSF) levels of beta-endorphin in
7 Japanese patients with Joseph disease and compared them with control
values. The 7 patients included 4 with type I and 3 with type II dise
ase; their mean age was 45.7 +/- 12.09 years. Diseased controls were m
atched in age to the patients studied. In these patients, CSF beta-end
orphin level was significantly lower than in the controls (40% of norm
al values). An alteration in CSF beta-endorphin level may explain some
of the neurological impairment found in Joseph disease.
