Gordon Holmes syndrome – first time diagnosed in Croatia
We present a 38-year-old woman with clinical presentation of ataxia, cognitive impairment, and secondary amenorrhea with remarkable brain hyperintensities on brain magnetic resonance imaging (MRI). Clinical symptoms began at the age of 20 years with the development of secondary amenorrhea, instabili...
