PA is helpful in treating severely impaired patients in the postacute phase, but the effect is restricted to ego-centered neglect. Lesions in the postcentral cortex (middle occipito-temporal, middle temporal, and posterior parietal areas) seem to limit the effect of PA.

Background: Fatigue is a common symptom in Multiple Sclerosis (MS) and body cooling may be an important non-pharmacological treatment strategy for fatigue by, for instance, reducing the loss of axonal conduction efficiency due to Uhthoff's phenomenon. However, up to now, no studies have demonstrated such a treatment effect for mentally induced fatigue.
