Background:
The objective of this study is to evaluate the oxidative stress status in patients affected by Alzheimer's disease, considering the role played by the free radicals in the progression and determination of this disease.
Methods:
We have studied 13 patients aged between 65 and 84 years and diagnosed with Alzheimer's disease on the basis of Brain CT scan or MRI results, PTEA (uditive mapped slow potential waves), EEG analysis, evaluation questionnaire (MMSE, ADAS), free radicals levels.
Results:
This study proved the presence of an oxidative stress status in all patients studied, showing an interaction between the disease and oxidative status. A reduction of the free radicals levels after therapy with determinable anti radicals has also been observed.
Conclusions:
The existence between Alzheimer's disease and oxidative stress has already been demonstrated. This study is a contribution to this orientation. Further studies are suggested on the preventive effects, but particularly to demonstrate if the use of antioxidants may be able to decrease or stop the evolution of this disease.
