This is a very pragmatic book, going over a detailed review in different aspects of the epidemiology, current nomenclature and symptomatic treatment of idiopathic basal ganglia calcification (IBGC), discussing also the fascinating questions raised by the basic research studies about the molecular basis of familial forms. This book guides the most focused readers into the intriguing puzzle of IBGC and the potential of such lesions to work as a model to explain the wide variety of symptoms manifested by its carriers. In addition, it is also a guide for neuropsychiatrists or neuroscientists who are seeking a "one source reference" to start basic or clinical research on this topic.
