The Gist
- Even though those amongst type ii diabetes (T2DM) convey double the opportunity of dementia there’s a paucity of operate examining the association betwixt diabetes handling together with opportunity of dementia.
- This is of import inwards lite of ongoing clinical trials evaluating insulin sensitizers every bit a potential handling for mild cognitive impairment together with Alzheimer’s disease.
- The objective was to evaluate the deportment upon of initiating novel diabetes therapies on time-to-incident dementia inwards a novel user cohort written report of patients amongst T2DMs to suit for confounding yesteryear indication.

The Highlight
- Researchers studied a cohort of 14,891 T2DM patients aged 55+ inwards the Kaiser Permanente Diabetes Registry who initiated whatever diabetes pharmacotherapy betwixt Oct 1999 together with Nov 2001.
- Only patients initiating unmarried novel therapies (“new users”) were included to cut confounding together with exercise mutually exclusive exposure groups.
- Researchers constructed Cox proportional hazards models to evaluate the deportment upon of initiating novel diabetes therapies on fourth dimension to dementia defined yesteryear medical tape diagnoses made inwards visits to principal care, retention clinics together with neurology from 1/1/2002-12/31/2007.
- Models were adjusted for age, race, instruction together with diabetes duration.
- 1487 (9.9 percent) patients were diagnosed amongst dementia inwards the 5 yr follow-up period.
- Of these 1487 patients 55 per centum initiated Metformin, 25 per centum Sulfonylurea, fourteen per centum Thiazolidinediones (TZDs), together with half dozen per centum insulin.
- With sulfonylureas every bit the reference grouping those initiating metformin had a twenty per centum reduced opportunity of dementia (Hazards Ratio {HR},=0.79, 95 per centum Confidence Interval {CI}, .65, .95), spell those initiating TZD or insulin had no deviation inwards risk.
- In comparing to those initiating metformin, those initiating SU had a 24 per centum increased opportunity (HR=1.24, 95 per centum CI 1.1,1.4), TZDs an xviii per centum increased opportunity (HR=1.18, 95 per centum CI 1.1, 1.4) together with insulin a 28 per centum increased opportunity (HR=1.28, 1.1,1.6).
- Findings were like when models additionally adjusted for glycosylated hemoglobin.
Conclusion
- In diabetic patients those initiating metformin had a 5 yr reduced opportunity of dementia inwards comparing to patients initiating other therapies.
- Animal models advise metformin may contribute to neurogenesis together with trials are evaluating metformin every bit a potential therapeutic for mild cognitive impairment. These results are preliminary show that benefits of insulin sensitizers may extend beyond glycemic command to neurocognitive health.
