Rare clinical disturbances of the brain stem mechanism as cerebellar fits and drop attacks

Cerebellar Fits (CF) and Drop Attacks (DA) are rare pathophysiological disorders of the Brain Stem (BS) and of the Cerebellar System (CS). Both have various etiologies (traumatic, vascular of tumoural). Both manifestations have an individual character. In this respect I would like to make 5 clinical observations (3 CF and 2 DA). These cases were verified clinically as well as by such methods as NMR (Nuclear-Magnetic-Resonance) CT-scan (Computer-Tomography-scan examination), BAEP (Brainstem-Auditive-Evoked-Potential), CCG (Cranio-Corpo-Graphy-based on a modified Unterberg's Test) and TDS (Transcranial-Doppler-Sound-examination), etc. In this short paper I wish to present some particular clinical aspects of the CF and DA.
