Cerebrovascular pathology in diabetic patients is associated with focal and diffuse cerebral lesions. Though structural brain abnormalities are not diabetes-specific, they are indicative of prognostication of developing cerebral blood circulation impairment in diabetics. Since pathogenesis of diabetic encephalopathy and its clinical-diagnostic manifestation depends on the type of diabetes mellitus, present investigation concerns differential peculiarities of diffuse and focal brain

Influenced by the type of basic disease, neuroimaging data of focal brain abnormalities in patients with diabetic encephalopathy require differential diagnostic and therapeutic approach. The prevalence of diabetes mellitus (DM) worldwide amounts to 240 million patients and it is expected to rise to 330 or even 500 million by the year 2030 [4]. Diabetic encephalopathy (DE), remaining the least studied chronic complication of DM, is considered to be cerebrovascular pathology, associated with focal and diffuse cerebral lesions [1, 2, 5]. Accompanied with metabolic derangements, cerebrovascular abnormalities and repeated severe hypoglycaemic episodes, kethoacidotic conditions have been implicated to create a unique clinical-diagnostic manifestation of DE [7, 9]. Being not diabetes-specific, structural brain abnormalities are indicative of detection of diabetic angiopathy and prognostication of developing cerebral blood circulation impairment [3]. Neuroimaging studies commonly reveal multiple small focal lesions, generally of periventricular localization, frequently followed by cortical atrophy and enlargement of the cerebral ventricles [3, 6, 8, 10-13]. Recent studies have reported an association between these changes and the patients' age [12, 13], severity of diabetes [3], neurological performance [6], and those neurovisual indices correlated with cognitive deficiency degree in DE patients [8, 10, 13]. Furthermore, due to the difference in pathogenesis of DE in various types of DM, further additional investigation is necessary concerning diffuse and focal brain abnormalities depending on diabetes type.
