Mind 167
thinker’ (Cross, 1973, p. 12). Lacking the restraint and self-doubt which true
education brings with it, he became perfectly positioned to make dire mistakes.
Hitler’s personality may have been subject to a series of more unusual
pathological influences. There is the matter of ill-health. From late 1942 he
experienced shaking limbs. This has been interpreted as a symptom of Parkinson’s
disease. The condition can be accompanied by mental changes including intellectual
deterioration, depression and paranoia. The onset of such a clinical state might help
explain the radicalisation of National Socialist policy during the war, but a diagnosis
of Parkinson’s disease remains uncertain. Hitler experienced trembling on just one
side of his body although the illness should afflict both sides. It is disputed whether
Hitler experienced the rigor in his limbs which also accompanies the disease (Eitner,
1994, pp. 204–5; Redlich, 1999, p. 234). The balanced judgement is that at most
Hitler suffered from a ‘low to moderate’ severity of the condition and that it
probably had no implications for the way his mind worked (Redlich, 1999, p. 234).
Another possibility involves Hitler’s heart. From 1932 he believed he had a
cardiac condition. His symptoms involved a strong heart beat, troubled breathing,
sweats, pressure in the chest and throat, and the sensation that the heart could stop
(Eitner, 1994, p. 194). From 1937 Hitler became particularly anxious about this. He
began to avoid exercise deliberately (Carr 1978, p. 144). In a meeting with senior
military men held in November 1937 (document 5.15) he raised the possibility of his
death (Maser, 1973, p. 213). An examination by his personal physician in 1940
indicated high blood pressure associated with some damage to the heart (Maser,
1973, p. 214). In July 1941 Hitler may have suffered a mild stroke during a vigorous
debate with Ribbentrop (Eitner, 1994, p. 199). The next month an
electrocardiograph indicated progressive arteriosclerosis. It is reasonable to assume
that fear of mortality related to worries about his heart must have intensified for
Hitler as time passed. From 1937 at least, his political actions were motivated in part
by a belief that his life expectancy might be limited.
Hitler’s personal physician, Dr Morell, prescribed Hitler a substantial array of
drugs. From 1937 to 1945 there were about thirty different medicines (Eitner, 1994,
pp. 208–10). These included a variety of stimulants, among them amphetamines.
Morell let Hitler take some of these as he required between 1939 and 1943, and it
is highly likely he abused them (including the amphetamines) (Redlich, 1999, p. 243).
Amphetamines reduce fatigue and provide a feeling of alertness, but they can be
associated with increased aggression, recklessness, anxiety, anger, transient
hallucinations, paranoid delusions, preoccupation with religious and philosophical
themes and a feeling of cleverness (Redlich, 1999, p. 239). It is possible that
amphetamine abuse increased Hitler’s recklessness in August 1939 as he geared up
to the invasion of Poland (Redlich, 1999, pp. 243–4). Either the direct consequences
of amphetamine misuse, or character change brought on by it, may also have had an
impact in Spring 1941 when he was planning Operation Barbarossa and thinking
about racial annihilation. A historian describes how Hitler presented himself at the
time.
