The doctor can look for potential underlying causes, including dementia, medication effects, or environmental factors, Elhelou says. From there, they can suggest effective ways to help you manage ...
Stress, hypometabolism, and oxidative damage may decrease physiologic reserve in the elderly and can lead to a decrease in neuron energy production and an increase in neuron damage. [12] Thioredoxin reductase is an antioxidant that neutralizes oxidative free radicals that can cause cell death. The brain is vulnerable to oxidative free radicals ...
Mild cognitive impairment (MCI) is a diagnosis that reflects an intermediate stage of cognitive impairment that is often, but not always, a transitional phase from cognitive changes in normal aging to those typically found in dementia, [1] especially dementia due to Alzheimer's disease (Alzheimer's dementia).
