Herein, we report on a patient with presenile dementia, intracranial calcification, and M-proteinaemia, which may play some part in the development of intracranial calcification with dementia. Plain brain CT and 123I-IMP SPECT. Brain CT showed severe calcification in the basal ganglia, floor of cerebral cortices, subcortical white matter, and cerebellum. 123I-IMP SPECT showed hypoperfusion in the frontotemporal lobes. A 66 year old man was admitted with dementia, which had been apparent since about 60 years of age. At the age of 62 he started to lose spontaneity and at the age of 66 gait disturbance occurred. In addition he showed slurred dysarthria, mild muscle rigidity, bilateral pyramidal signs, and mild … ER -
