The Role of White Matter Disconnection in the Symptoms Relating to the Anarchic Hand Syndrome: A Single Case Study

Valentina Pacella, Giuseppe Kenneth Ricciardi, Silvia Bonadiman, Elisabetta Verzini, Federica Faraoni, Michele Scandola, Valentina Moro
2021 Brain Sciences  
The anarchic hand syndrome refers to an inability to control the movements of one's own hand, which acts as if it has a will of its own.  ...  Furthermore, an analysis of the neuroimaging regarding structural connectivity allowed us to investigate the grey matter lesions and white matter disconnections.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...
