Description
INTRODUCTION: Senile degeneration of the brain refers to a progressive decline in cognitive function, memory, and behavior associated with aging and neurodegenerative processes. These changes may arise from normal aging, pathologic conditions such as Alzheimer’s disease, or metabolic disturbances that affect neuronal function. Degenerative changes within the brain are often observed in the hippocampus, a structure located in the temporal lobe that plays a critical role in memory formation and consolidation. Due to its involvement in cognitive processing and vulnerability to neuronal damage, the hippocampus is frequently examined when evaluating neurodegenerative changes in brain tissue. This study will examine histologic features of hippocampal tissue obtained from postmortem brain samples of a Caucasian male and female of similar age in order to identify, compare, and contrast degenerative changes present within the hippocampus.
METHODS: This is a comparative cadaver study using left and right hippocampal tissue obtained from postmortem brain specimens of an 86-year-old male and an 87-year-old female. The hippocampal tissue was carefully dissected and submitted to Colquitt Regional Medical Center’s (CRMC) pathology laboratory for histologic slide preparation and microscopic evaluation using standard histologic staining techniques by a pathologist to assess potential degenerative changes within the hippocampus. We will also use the current research on hippocampal degeneration and compare that to the results we find from the samples sent to the CRMC pathology laboratory.
RESULTS: Previous studies have shown correlations between estrogen levels and hippocampal degeneration. The hippocampus has a high density of estrogen receptors, which play a role in the neuroprotective effects. When comparing the samples of the male and female, we anticipate that the female will have more hippocampal degeneration, which can be compared to the literature. This research is ongoing, and results are pending.
DISCUSSION: Due to a great decrease in estrogen in postmenopausal women, we expect that there will be higher rates of degeneration in women compared to men of similar age. Literature has shown that typically, the vascular degeneration of the brain affects men more than women, but hippocampal degeneration has a greater effect on women due to the estrogen receptors. Estrogen has also been linked to synaptic plasticity for learning and memory. This leads to another conclusion that we are considering about how postmenopausal women may suffer from increased brain fog and memory issues.
