How to diagnose Dementia
MRI scans determined a shrinkage in the mid-brain due to Alzheimer's disease diagnosed as neurodegenerative disease. The number reason for dementia is Alzheimer disease. Signs that characterize the disease are memory loss, disorientation, difficulty with reasoning with the decline of language and thinking skills. In the past an autopsy was the only conclusive diagnoses. Florida researches have acquired diagnoses with the MRI with the findings of shrinkage and atrophy of the medial temporal lobe. Narrowing to the three structures that are vital for the conscious memory of facts and events. The research compared 260 people with probable Alzheimer's disease divided by two groups one with degrees of cognitive loss and mild memory loss and the other group with no memory loss. The research found that the people that didn't have memory loss did have atrophy of the brain with the onset of memory loss within a year or two later. The MRI can detect who will get the disease before the onset of dementia. "Researchers at Miami's Wien Center and USF's Byrd Institute are developing drugs that attack mechanism that lead to death of nerve cells associated with the diseases." Accurate diagnoses will allow for the use of these drugs earlier and stop the progression of the disease.

Loss of smell is an early sign of Alzheimer's disease (AD) a study in the Journal of Neuroscience. A protein amyloid that is accumulated in the brain affects the smell senses. The formation of amyloid plaques and neurofibrillary tangles are found in MRI scans are contributed to the death of neurons in the brain. The test were on genetically created mice that developed amyloids in the brain showed signs of a human form of AD. The mice were unable to differentiate between smells. Even the smallest presence of a amyloid effected the mice's ability to smell.
