Interneurons in the CA1 stratum oriens expressing αTTP may play a role in the delayed-ageing Pol μ mouse model.

Neurodegeneration associated with ageing is closely linked to oxidative stress (OS) and disrupted calcium homeostasis. Some areas of the brain, like the hippocampus - particularly the CA1 region - have shown a high susceptibility to age-related changes, displaying early signs of pathology and neuronal loss. Antioxidants such as α-tocopherol (αT) have been effective in mitigating the impact of OS during ageing.

Neurodegenerative Diseases: A Multidisciplinary Approach.

The rapid pattern of population ageing in recent years increases the risk of appearance of associated neurodegenerative diseases. Dementias are one of the most feared disorders, and although not necessarily all elderly people have dementia, the number of people with this disease is increasing rapidly. The causes of dementia are multiple, and the diagnosis of the different types of dementia is complicated since most patients display mixed dementias and symptoms overlapping.
