Palm-chin reflex in acute ischaemic stroke.

The majority of 71 cases with acute cerebrovascular ischaemic stroke displayed an absence of the palm-chin (palmomental) reflex in the affected part of the body, during the first three weeks, poststroke. After this period the reflex is present again. In our opinion, the absence of the palm-chin reflex in the acute ischaemic stroke shows a more important semiologic value than its presence.
