ResumoMany psychiatric symptoms have been described in pernicious anaemia, including depression, manic excitement, paranoid states, confusional episodes, and dementia. Although vitamin B 12 deficiency is known to produce neurological symptoms there is much less certainty about its role in producing mental symptoms. Despite this uncertainty, it has been asserted that carrying out vitamin B 12 assays on psychiatric patients will enable doctors to cure for good severe disabling disease which otherwise may end in chronicity (Edwin et al. , 1966). Routine examinations to exclude pernicious anaemia have been advocated for all psychiatric patients (Strachan and Henderson, 1965; Hunter and Matthews, 1965). A prudent preliminary is a critical evaluation of the causal relationship between vitamin B 12 deficiency and individual psychiatric syndromes.
