BACKGROUND AND PURPOSE We studied the value of clinical and electroencephalographic assessment in patients with acute first-ever supratentorial ischemia in predicting functional outcome after 1 year. METHODS In 55 consecutive patients admitted after a median interval of less than 24 hours, the degree of handicap was dichotomized as moderate (Rankin grade 1, 2, or 3) or severe (Rankin grade 4 ...

A particular game-theoretic model (Grafen, 1990) of the evolutionary stability of honest signalling, which attempts a formal proof of the validity of Zahavi's (1975, 1977) handicap principle, is generalised and rendered as an evolutionary simulation model. In addition to supporting new theoretical results, this allows the eeects of diiering initial conditions on the attainability of signalling ...

background: dizziness as a common symptom affecting many aspects of the patient’s life and it is hard to be fully evaluated. the dizziness handicap inventory (dhi) is a reliable self-perceived questionnaire in the evaluation of dizziness impacts. the purposes of this study are translation of the dhi to persian language and measuring its psychometric properties, including face, content, discrimi...

The Handicap Principle represents a central theory in the biological understanding of signaling. This paper presents a number of alternative theories to the Handicap Principle and argues that some of these theories may provide a better explanation for the evolution and stability of honest communication.
