[Maximal motor nerve conduction rate with lithium]

We examined the nerve conduction velocity (NCV) of 10 patients under long-term lithium therapy and 10 patients after a 3-month lithium therapy. In accordance with the literature concerning patients and normals under experimental treatment with lithium, we also found reduced NCV values. There were no significant changes in NCV during the first 3 months of lithium treatment. This could be due to the relative low lithium levels as well as to symptoms of manic-depressive Illness and the nerve examined.
