Permanent brain damage following parasuicide with severe insulin-induced hypoglycaemia

The brain is continuously dependent on glucose as its energy substrate. When vulnerable areas (hippocampus, cerebral cortex, basal ganglia, caudoputamen) are exposed to protracted neuroglycopenia, irreversible neuronal necrosis with permanent cerebral damage or brain death may result [1, 2, 3].
We present a case of parasuicide with an overdose of insulin that caused protracted hypoglycaemia with permanent brain damage. We propose that the acute inflammatory and rheological response to hypoglycaemia with subsequent intravascular thrombosis provoked multi-territorial cerebral infarctions, therefore, representing an atypical pathogenesis of hypoglycaemic brain damage.
A 68-year-old woman with a 40-year history of type 1 diabetes and a history of depression and chronic alcohol abuse was found at home in a deeply comatose state. Her blood glucose concentration was too low to be estimated. Verifiably, approximately 6 h earlier, she was observed by her relatives to be conscious...
