- Abstract
- The authors reviewed the medical records of 78 patients diagnosed as amyotrophic lateral sclerosis (ALS) at the Department of Neurology of Seoul National University Hospital from January 1980 to June 1986. The clinical features, serum CPK value, electromyographic findings and muscle biopsy findings were analysed.
Results obtained were as follows:
1. The mean age of onset was 44.4 (17-68) which was about 10 years earlier than that
in the reports from other countires. The sex ratio (male to female) was two to one
(52:26).
2. The most common from was conventional type (48.7%), followed by
pseudopolyneuritic type (30.8%) and bulbar type (20.5%).
3. Muscle weakness (100%), muscle atrophy (97%), hyperreflexia (94%), fasciculations
(82%), bulbar signs (67%), frontal release signs (31%), Babinski signs (27%) and
sensory deficits (5%) were observed. Four cases with sensory deficits proved that they
were accompanied with carpal tunnel syndromes.
4. The mean interval from onset to generalization of symptoms was shorter in bulbar
type (10.6 months) than in non-bulbar type (16.6 months), suggesting a more
progressive course in the former.
5. Serum CPK value was checked in 62 cases. An increase up to four times the
normal value was observed in 17 cases (27%).
6. EMG (N=73) revealed such abnormal findings in 70 cases (95.9%) as increased
insertional activities, fibrillations, positive sharp waves, reduced interfernece patterns,
fasciculations and giant motor unit potentials. No abnormal findings were found in three
cases, however.
7. Muscle biopsy (N=61) showed neurogenic atrophy with various changes in 56 cases
(92%), massive fatty infiltration in 4 cases and muscle fascia only in one case.
