Answers are grounded in this paper and cite their sources.
Acetazolamide may be effective in preventing attacks and improving myotonia in sporadic cases of hyperkalemic periodic paralysis.
Sporadic cases of hyperkalemic periodic paralysis are rare. We studied a 2-year-old girl with clinically typical hyperkalemic periodic paralysis except for a negative family history. Results of genetic and provocative testing in immediate family members suggest that hyperkalemic periodic paralysis may be genetically heterogeneous. Acetazolamide prevented attacks and improved myotonia in this sporadic case.
