Health Association, has recently carefully summarized the rôle of
syphilis in the production of insanity, and the cost of the disease to
the State from the standpoint of mental disease alone. He estimates
that 10 per cent of the patients who enter the Massachusetts State
hospitals for the insane are suffering from syphilitic insanity. Fifteen
per cent of those at the Boston Psychopathic Hospital have syphilis. In
New York State hospitals, 12.7 per cent of those admitted have
syphilitic mental diseases. In Ohio, 12 per cent were admitted to
hospitals for the same reason. An economic study undertaken by Williams
of 100 men who died at the Boston State Hospital of syphilitic mental
disease, the cases being taken at random, showed that the shortening of
life in the individual cases ranged from eight to thirty-eight years,
and the total life loss was 2259 years. Of ten of these men the earning
capacity was definitely known, and through their premature death there
was an estimated financial loss of $212,248. It cost the State of
Massachusetts $39,312 to care for the 100 men until their death.
Seventy-eight were married and left dependent wives at the time of their
commission to the hospital. In addition to the 100 men who became public
charges, 109 children were thrown upon society without the protection of
a wage-earner. Williams estimates, on the basis of published admission
figures to Massachusetts hospitals, that there are now in active life,
in that state alone, 1500 persons who will, within the next five years,
be taken to state hospitals with syphilitic insanity.
