Serum creatine kinase (CK1) values were recorded while or soon after the diagnosis of amyotrophic lateral sclerosis (ALS) was established in 140 of 217 (65%) consecutive patients seen in the Motor Neuron Disease Clinic at this center during a 5-year period. Second creatine kinase (CK2) determinations were recorded on 48 of 140 (34%) ALS patients later in the course of the disease. The mean CK1 and CK2 values (unit, times the upper limit of normal) were 1.22 (range, 0.1 to 3.0; median, 0.80) and… CONTINUE READING
