Serum calcium levels were measured in 25 chronically ill psychotic inpatients with involuntary movements, in comparison with 25 otherwise indistinguishable patients without such a syndrome. Those with involuntary movements were significantly more likely to have a serum calcium level below the normal range. These results are discussed in terms of the role of calcium in neuronal dysfunction, and in broader aspects of the general biological disadvantage that appears to characterize older patients with this movement disorder.
