In the 1950s, the population aged over 65 years continued to increase, and older people occupied mental hospital beds disproportionately. A few psychiatrists and geriatricians demonstrated what could be done to improve the wellbeing of mentally unwell older people, who were usually labelled as having irreversible 'senile dementia'. Martin Roth demonstrated that 'senile dementia' comprised five different disorders, some of which were reversible. These findings challenged established teaching and were doubted by colleagues. Despite diagnostic improvements and therapeutic successes, clinical practice changed little. Official reports highlighted the needs, but government commitment to increase and improve services did not materialize.
