Serum creatinine phosphokinase activity in psychiatric patients receiving electroconvulsive therapy
The Journal of Clinical Psychiatry
|March 1, 1981
Summary
Electroconvulsive therapy (ECT) did not elevate brain creatine phosphokinase (CPK) levels, suggesting it does not cause brain damage. A minor increase in skeletal muscle CPK was observed post-treatment, remaining within normal limits.
Area of Science:
- Neuroscience
- Biochemistry
- Clinical Medicine
Background:
- Serum creatine phosphokinase (CPK) elevation is linked to organic brain pathology.
- Electroconvulsive therapy (ECT) has been questioned for potentially causing brain damage.
Purpose of the Study:
- To investigate whether electroconvulsive therapy (ECT) causes an elevation in brain-specific creatine phosphokinase (CPK) levels.
- To assess the impact of ECT on serum CPK levels and determine if brain damage occurs.
Main Methods:
- Patients undergoing ECT were monitored for serum CPK levels.
- CPK levels were analyzed to differentiate between brain and skeletal muscle types.
Main Results:
- Serum CPK levels in patients receiving ECT remained within normal limits.
- A slight increase in skeletal muscle type CPK was observed after ECT.
- No instances of brain type CPK isolation were detected.
Conclusions:
- ECT does not appear to cause significant brain damage as indicated by normal brain-type CPK levels.
- The observed minor rise in skeletal muscle CPK post-ECT is not indicative of brain injury.
