- Abstract
- (en) [Cognitive impairments and dementia in elderly diabetic patients] Type 2 diabetes can induce cognitive impairment in the elderly through different mechanisms which may be interrelated. Alongside cerebrovascular damage and Alzheimer’s-type neurodegeneration, there is also a form of diabetes-related dementia in which cognitive impairment essentially concerns executive and attentional abilities, rather than short-term memory abilities. Systematic cognitive screening is indicated in elderly diabetic patients, especially if they are responsible for their blood sugar monitoring and drug treatment. Among the various tests validated for screening cognitive deficiencies, the Mini-Cog (or Codex, its French version) examines the cognitive functions (executive, attentional, visuospatial) that diabetes preferentially alters. It is simple and quick, and therefore usable for consultation. An abnormal result (class C or D), found in approximately a third of elderly diabetic patients, must lead to a thorough cognitive evaluation in order to refute or confirm the diagnosis of cognitive impairment, and to determine its severity. There is no recognized benefit of primary prevention at present. Secondary prevention therefore makes perfect sense. It consists of identifying cognitive deficiencies to adapt patients’ daily lives by organizing the necessary assistance, in order, among other things, to prevent medication errors and the complications that follow.
