Human diabetes is associated with cognitive impairment and structural abnormalities in the brain such as cerebral atrophy. The aetiology of these abnormalities is not known. The BB/E rat is a well-established model of type 1 (insulin dependent) diabetes. A cohort of 34 BB/E rats with diabetes was divided into three sub-groups according to age (and duration of diabetes). Basal ganglia calcification (BGC) was present in the brains of more than 50% of diabetic animals, but not in any of 37 non-diabetic BB/E rats. BGC occurred more commonly in those animals which had the longest duration of diabetes (p=0.001), such that BGC was present in only 8% of animals with diabetes for 20 weeks, but in 100% of animals with diabetes for 60 weeks. There were no other significant light microscopic neuropathologic changes in diabetic animals. It will be important to investigate the mechanism of brain calcification, whether a similar process occurs in humans with diabetes, and its possible relationship to cognitive decline.

BACKGROUND Basal ganglia calcification (BGC) is a rare sporadic or hereditary central nervous system (CNS) abnormality, characterized by symmetric or asymmetric calcification of the basal ganglia. CASE REPORT We report the case of a 65-year-old Gypsy female who was admitted for a tetanic seizure, and who had a history of polyneuropathy, restless-leg syndrome, retinopathy, diabetes, hyperlipidemia, osteoporosis with consecutive hyperkyphosis, cervicalgia, lumbalgia, struma nodosa requiring thyroidectomy and consecutive hypothyroidism, adipositas, resection of a vocal chord polyp, arterial hypertension, coronary heart disease, atheromatosis of the aorta, peripheral artery disease, chronic obstructive pulmonary disease, steatosis hepatis, mild renal insufficiency, long-term hypocalcemia, hyperphosphatemia, impingement syndrome, spondylarthrosis of the lumbar spine, and hysterectomy. History and clinical presentation suggested a mitochondrial defect which also manifested as hypoparathyroidism or Fanconi syndrome resulting in BGC. After substitution of calcium, no further tetanic seizures occurred. CONCLUSIONS Patients with BGC should be investigated for a mitochondrial disorder. A mitochondrial disorder may also manifest as tetanic seizure.
