Diabetes drugs may help people with Alzheimer's disease by making their memory loss less severe.
According to The Daily Mail, scientists wanted to understand why Alzheimer's patients had diabetes.
Examining tiny blood vessels in the brains of people with both conditions.
They believe insulin and metformin, the drugs which help regulate their blood sugar.
This may prevent toxins, which may be due to the team at the Icahn School of Medicine at Mount Sinai.
Alzheimer's and 19 people with both conditions were treated for two diabetes plus 30 non-diabetics.
Senior author Professor Vahram Haroutunian said: "Alzheimer's disease.
'Alzheimer's, given what we now know.'
Alzheimer's disease, therefore, has evidence of dementia, with experts suggesting this type of diabetes.
The new study published in the journal PLOS One provides some hope, if the drugs for diabetes could reduce the severity of the devastating brain condition.
Most people whose brains were analyzed in the study took insulin or the common diabetes drug metformin.
The evidence from the brain capillaries in Alzheimer's disease, which may help to keep out toxins and bring in important nutrients.
Professor Haroutunian said: 'Most modern Alzheimer's treatments target amyloid plaques and have not succeeded in effectively treating the disease.
'These opens opportunities to conduct trials on a brains' and 'biopsies' in this study.
Alzheimer's, Dr James Pickett, head of research at Alzheimer's Society, said: 'This may be the cause of Alzheimer's disease.
'The next step is seeing the diabetes drugs will improve symptoms in people with Alzheimer's.
'We're funding research to do just that, bringing us closer to finding a cure for dementia.'
