The Third Reich at War, 1939-1945

by Richard J. Evans

But he was unable to deal effectively with Hitler’s physical deterioration under the strain to which he was now subjecting himself. From 1941 onwards electrocardiograms began to show progressive heart disease, probably caused by sclerosis of the coronary arteries. Beginning in the spring of 1943 Hitler suffered from chronic indigestion, with periodic stomach cramps (at least twenty-four bouts by the end of 1944), which may have been made worse by Morell’s treatment. A tremor began in his left hand, becoming markedly worse from the end of 1942, and accompanied by a growing stoop and jerking movements in his left leg. By 1944 he was shuffling rather than walking, and the symptoms of a mild but generally worsening case of Parkinson’s disease were becoming clear for all medically informed observers to note.
