The Electroencephalogram, Psychological Testing, And other Investigations in Abstinent Alcoholics: a Longitudinal Study
Sixty-seven abstinent alcoholics were examined two weeks after admission by electroencephalography and psychometry. Fifty-two returned for retesting one month after withdrawal, twenty-three at two months and thirteen at six months. Over half showed some E.E.G. abnormality at first testing, paroxysmal disturbances being the predominant finding. There was a positive relationship between abnormality in the E.E.G. and severity of psychometric impairment at each assessment. Psychometric improvement was not related to initial E.E.G. findings.
A possible relationship between E.E.G. abnormality and clinical malnutrition and folate deficiency was demonstrated. In the serial studies some reversal of E.E.G. abnormality occurred between the first and second tracing which also appeared to be related to malnutrition.
