OBJECTIVES We addressed three questions: Have recent improvements in old-age disability been mirrored in changes in self-reported general health status? Are general health status trends similar for younger and older Americans? Have changes in general health status been uniform across demographic and socioeconomic groups? METHODS Using logistic regression, we analyzed data from the 1982-2003 N...

Mirror neurons, discovered by Rizzolatti et al. in the 1990s , have been the subject of much debate. There are many theories regarding their possible function, both evolutionarily as well as in day to day life. It has been proposed that mirror neurons are the single neuron substrates of the Common Code , which links perceptual and action representations to allow the brain to predict of the outc...

Mirror movements correspond to involuntary movements observed in the limb contralateral to the one performing voluntary movement. They can be observed in Parkinson's disease (PD) but their pathophysiology remains unclear. The present study aims at identifying their neural correlates in PD using functional magnetic resonance imaging. Ten control subjects and 14-off drug patients with asymmetrica...

BACKGROUND AND PURPOSE Our purpose was to investigate the association between cervicomedullary neuroschisis and mirror movements in patients with Klippel-Feil syndrome (KFS). METHODS We conducted a retrospective analysis of 23 patients with KFS who were seen at our institution during a 10-year period. Sixteen of the 23 patients had undergone adequate axial view cross-sectional imaging of the ...

In this report are described seven patients assessed clinically and neuropsychologically in whom mirror movements affecting predominantly the hands occurred as a congenital disorder. These mirror movements, representing a specific type of abnormal synkinesia, may arise as a hereditary condition, in the presence of a recognisable underlying neurological abnormality, and sporadically, and the sev...

E xamination of patients for the presence or absence of mirror movements does not normally form part of a routine neurological investigation nor is this simple part of the motor examination normally taught to medical students and trainee neurologists. The examination requires the examiner only to observe both hands during voluntary fine finger movements of each hand in turn; for example, sequen...

BACKGROUND Moebius syndrome is a rare disorder with minimum clinical criteria of congenital facial weakness in association with impairment in abduction of one or both eyes. Mirror movements are not known to be associated with Moebius syndrome. CASE REPORT We present three patients who meet minimum criteria for a diagnosis of Moebius syndrome and who also display mirror movements. DISCUSSION...
