Concerningly, 35.7% of patients were incorrectly classified by at least one of the three screening procedures that were examined. The researchers looked at the well known Mini-Mental State Examination (MMSE), the Memory Impairment Screen (MIS) and animal naming…

Could Alzheimer’s disease (AD) be due to a viral cause? This idea links to the importance of olfactory impairment in the early stages of neurodegenerative diseases, such as Alzheimer’s. A few years ago an editorial was published in the Journal of Alzheimer’s Disease. Many luminaries in the field co-authored the paper. They discussed multiple studies…
Impaired sense of smell (anosmia) is an early warning sign of neurodegenerative diseases, such as Alzheimer’s dementia, Parkinson’s disease, Korsakoff’s syndrome, Lewy-body dementia, HIV-related dementia, and multiple sclerosis. Anosmia may occur in other conditions, too, such as diabetes. Anosmia does not affect all patients with neurodegenerative illnesses, but it is nonetheless frequent enough to be…

Recently, researchers were amazed to find a seven-fold increase in bacterial counts in the brains of patients with Alzheimer’s disease. The increase was mainly due to the presence of oral bacteria, the bugs that make up the microflora of the mouth. A number of…
