The blood pressure and pulse rate were measured in supine position, immediately after standing up and after 1, 3, 5 and 10 min of standing. OH was defined as a reduction of systolic blood pressure (SBP) of at least 20\u2009mm Hg or a reduction of diastolic blood pressure (DBP) of at least 10\u2009mm Hg.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>OH occurred in 69% of the DLB patients and in 42% of the AD patients, but only in 13% of the controls (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001 controls <jats:italic>vs<\/jats:italic> AD and controls <jats:italic>vs<\/jats:italic> DLB, <jats:italic>p<\/jats:italic>\u2009=\u20090.001 AD <jats:italic>vs<\/jats:italic> DLB) The DLB patients had a greater drop in SBP than the other study groups during orthostatic challenge and had a more prolonged period of orthostasis. The pulse drive on orthostatic challenge was similar in between groups. However, in the DLB group it was not adequate to restore the blood pressure to supine values.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Patients with DLB react different to orthostatic challenge than patients with AD or controls, with important clinical implications for key disease symptoms and treatment.
